Anyone use a CP/M machine for BBSing? What terminal program do you use? I've settled on QTerm as it has VT100 support built in. However screen clearing doesn't seem to work with Mystic's pipe CL. Once the last line (say row 24
for example) is reached then everything just gets written over on that last line and the screen never advances or clears.

Been a couple years since I last used it, but I recall it working on other
BBS software. I'll have to do more testing to know for sure.

With VT100 emulation off QTerm is working just fine, just no screen clearing etc.

Only other "issue" I have with this Kaypro 4 is that I can't use a baud
faster than 1200 without dropping characters. Kind of sucks lol, I much
prefer 2400 baud.

Here is a picture of my Kaypro 4 as set up and connected to my BBS (still in configuring/customizing phase):

I have to laugh. My VT100 issues were a PEBKAC error. VT100 is of course a predecessor of ANSI and so QTerm with VT100 enabled works very well with an ANSI theme. Mystic's auto detection was detecting it as ASCII. So now I have it configured to simply let the user choose which emulation and theme they
want ebfore they log in.

Even works well with the full screen editor. Though at 1200 baud it is
painful.

Doug

Beautiful machine, and I read your next post - glad you got it figured out by allowing user to select terminal settings. :P

Really fun - and your K4 looks great.

I have a Kaypro 4/83 and a Kaypro "1" (Kaypro 1 with a 2/84 ROM).

I use a WiModem232 for both and FastTerm.

FastTerm is pretty bare bones - basically just takes keys and sends them, then displays what comes back on the screen. No emulation.

Only other "issue" I have with this Kaypro 4 is that I can't use a baud faster than 1200 without dropping characters. Kind of sucks lol, I

I found that if you have any emulation, the computer can't keep up. That's why I went with FastTerm. I easily get 2400 BPS without any character drops.

I also use the Kaypro "baud" ("baudm" on my Kaypro "1") program to lock the serial port to the speed I want.

For file transfers, I use Kermit and a null-modem-to-USB cable. But sending to the Kaypro is limited to 300 BPS. I find that's mostly due to the delay in saving the data to disk. Otherwise, I would be able to get a much higher speed.

I wonder what kind of UART they used on old CP/M boxes? With DOS boxes they originally had a 8250 UART chip that wouldn't support speeds over 9600 (if
you were lucky). 16450 and 16550 UARTs added an on-chip buffer that allowed bits to "back up", so to speak, and higher rates were possible.

Based on the Kaypro manuals that I've been able to locate, they didn't have a modern-type UART.

The schmatic lists WD1943/SMC8116 and 3884/0 SIO chips.

I know in my RC2014, they use a Z80 SIO/2 chip with a 74HCT04 and 74LS138 for providing 2 serial ports. But that system supports speeds up to 115,200 BPS.

Like I said, it looks like my Kaypro can handle much higher speeds. But it's I/O for the other things that causes the problems. It's like there's no buffer on the serial port at all. Get the character when it's there because it will be overwritten soon.

First, sorry for the late reply.

My favourite activity on any retro computer that isn't game-focused is
BBSing. So I "need" VT100 emulation for that to satisfy my expectations for what a BBS session should be like.

I'll have to look around for FastTerm though just to give it a try. I really need to buy another HxC floppy drive emulator though. I'm supposed to be shrinking my retro computer collection but it started growing again. I'm currently working on resurrecting a COMPAQ 286 and I've got the floppy drive emulator there for the time being. 1st world problems!

For that, you'd probably be better off with something more powerful than the Z80era of computers. Anything 8088 and up should work fine.

Also, that era of computer will have a modern, dedicated UART which will allow higher serial port speeds. Even better if you can track down a Hayes ESP (Ehnanced Serial Port) card.

I'm limited by desk space. If I don't use my machines every so often, I feel like I'm wasting them. But I have to keep some of them in the shelves because I have no desk space for them. So that feeling of guilt keeps me from acquiring more.

No doubt. And while I never used to consider x86 DOS PC's as retro, enough
time has passed that I've started feeling nostalgic for them. So I've got a few lol. Working on a COMPAQ 286 now, waiting on a RTC chip replacement. Of course what I really want is an IBM XT but they're out of my price range
right now.

Considering the subject, I should give CP/M-86 a try.

Yup, me too. Not just Fido BBSes but there were a wide variety that would
let you choose between straight ASCII or ANSI/VT100. I've got a pre-login
menu on my own BBS for that but I haven't put enough time into the ASCII version as I should so its got plenty of glitches at the moment.

Ya, I had an idea of picking up just a XT case, then putting a RaspberryPi in itand running a DOS emulator to get that retro feel. But even just the case is pricy today.

Seriously, I've had in the back of my head to do something like that. I also wanted to try DR-DOS to see how that feels.

It's easier today to try those things out since most of us have replaced the hard drives with CF cards. Not to mention we don't have to pay for CP/M-86 or DR-DOS today.

There was MP/M, the multi-user CP/M OS. It supported different users
on terminals on a Z80.
AFAIR on x86, it was also available.
And there was Concurrent CP/M on x86, I guess it also supported
virtual terminals and multitasking.

But the bare CP/M did not support multitasking, neither on Z80 nor on
x86.

Sort of. Not multi-user like Linux (where multiple people can use the same box at the same time), but it had a "user" attribute that you could put on files as a way to group them or hide them.

CP/M didn't support subdirectories. Which wasn't a surprise in a day when the only storage media you had was single or double sided 5.25" floppies. So we are talking 180K or 360K. You basically had a floppy with the software you wanted to run in the A: drive, then your data disk in the B: drive.

I need to research the reason that the "user" attribute was created in the first place. I don't know off hand. But when hard drives started coming down in price, not supporting subdirectories was a big problem. Imaging doing a "dir" command and having to scroll through 100+ files - most unrelated to what you were doing.

So CP/M used the "user" attribute as sort of a way to handle subdirectories.

user 0 would be all the system utils, for example, and seen by all. Then you switched to user 1 when you wanted to program. Maybe switched to user 2 for writing that research paper. Switching to a different user would hide the files for the other users. Now your "dir" command only showed the files related to the user you had set.

Right now, my CP/M machines are Kaypros and my RC2014s - all running CP/M 2.2 on a Z80. So they may have addressed this in newer versions of CP/M. I have it on my list to play with CP/M-86 to see what that does. I think I can run that one my MS-DOS machines.

In my case, I got into vintage computing because of a real problem I had at work.

I grew up with personal computers (the first on I used was TRS-80 Model I Level II and it was NEW at the time) so I always have in the back of my mind as I develop software that resources are limited and I need to keep an eye on how I use them.

The problem at work was related to a new developer (who first started using computers that had far more resources than he could use). The tl;dr is that he pumped 1GB files through the system I was supporting that was designed to handle files only 10,000MB max. The idea that sending in a file 1000 larger than he originally told us he was going to send was going to be a problem didn't even enter his mind.

Working with these very limited resource machines and seeing how much you can really do with these old computers is really interesting. And reminds us that computers don't have infinite resources.

It would be fun to have a collection of x86 DOSes in the box with disk/manuals.

Everything's on line today. No disks and manuals, but disk images and PDF files of the original manuals.

I think I only have 1 computer that actually uses floppy disks today. This is mostly because I actually want to use these machines and floppies are getting harder and harder to locate (especially the 5.25" floppies).

The last batch of 5.25" floppies I could locate had a failure rate of 2 out of 3 disks.

Didn't DR-DOS become Caldera DOS and then FreeDOS? Not sure.

I think you are right about Caldera, but I thought FreeDOS was a complete rewrite.

I did give FreeDOS a try on my Compaq Portable 386 and I wasn't impressed with how it worked over the original DOS 3 that came with the machine.

I know that there was a program called Double Duty for the TRS-80 line. It let you load 2 programs into memory and swap between them. But I think that was the most the Z80 could do along the idea of "multitasking".

Sure, but a big part of my collecting had always been software (in boxes if possible), manuals, etc. I always like the big manuals in three ring binders
as you could easily refer to them while using the software or programming language. I have tons of such items for my TRS-80 Model 4, but not much for other systems like early PC's as I have essentially stopped collecting
(failing at that a bit lol).

floppies are getting harder and harder to locate (especially the 5.25" floppies).

That's because people like me are hoarding them. I have hundreds. Half are new. I do like using things like HxC floppy emulators for convenience, and
CF drives for their quietness, but all in all I prefer to use original
hardware where possible for (sadistic) realism.

Ya, I have limited space, so I need to pick and choose what's worthwhile to make the space for. I do have good number of computer books and manuals, but I don't have a set for all my systems. If I did that, I'd have to choose between the computer or the books and I'd rather have the computer.

I try really hard to NOT get new stuff, but sometimes something comes up on eBay that I really want (or no one wants, but I think it cool and I get it cheap).

That's because people like me are hoarding them.

I have a bunch too. But like I said, when I go to format them, they have a 2 out of 3 failure rate. They are just getting too old.

It would be fun to have a collection of x86 DOSes in the box with disk/manuals.

Back in the day there was a version of OS/2 Warp that was hacked to remove
the GUI and you were left with a 3-disk installer of just the CLI. It was
like having DOS 5 (or maybe 6?) without the 640k RAM barrier. It ran
absolutely great, but it didn't have emm386.sys so anything that specifically checked for that didn't run. I'd really like to find a copy of that again.

Interesting. Never heard of that one. I've used version 3 and 4. Great OS. Would have been a solid system to use back when it was current. I never did due to cost, and things in the OS world were moving so fast by the time I
could afford it Win95 was ubiquitous.

Thanks. I've been racking my brain as to what commercial machines would have run MP/M. I'm aware of the Kaypro-era (and many of the competitors during that time) all running CP/M.

My thinking right now is that the ascendancy of MS-DOS really overshadowed any enhancements of CP/M. Like any technology, you have companies who made the investment in that technology and don't want to spend the money to change that, so they create a demand for updates to the "old" technology. For a while, at least.

"Concurrent CP/M" is still from Digital Research, as I've read on Wikipedia (.de), Concurrent CP/M-86 is a later version of MP/M-86 + CP/M-86.

Ahh.. That's right. More CP/M history I'm forgot about.

Don't underestimate the Z80 :)

I don't. It's pushing 40 years old and still being manufacturered. They must have done something right.

The bulk eraser might fix the problem - for a time. But the fact is that, over time, the disks will simply no longer hold the data. Some of the poorer quality ones will actually flake and make your drive heads dirty (good luck buying a new 5.25" drive head cleaner today).

Like I said, I fully understand wanting to use the old disks in these old systems. I had my Kaypro "1" (actually a 2/84 in a 1 case) like that for a while. The 1/2 height drives were much more reliable than the full height ones that were in my Kaypro 4/83. But whenever I wanted to use it, I had to make room for the disk case. And I had some disk failures.

My TRS-80 4P still has its floppy drives and I still have a 1541 for my Commodore 64. But I never use them. Software mostly comes from the Internet as a disk image file, making the floppy emulators that I have for both even more convienent.

A far bigger problem I come across, is mouldy floppies. Who'd have thought they'd support mould growth... looks a bit like slightly green grey rings on the disc surface. Clags drive heads really badly really quickly. A fairly common problem on SS and DSDD discs.

ZX80/81 owners unite. Research is currently underway into a version
of UNIX for the stock standard ZX81, call ZUNIX. Using a new mega
super ultra data compression method (involves a hyrdraulic press) the
follow features have been implemented in ZUNIX -

* Runs in the standard 1.5K. No need to go for that wasteful
extra 4K or 16K RAM upgrade.
* Will be licensed in 100 and 200 user versions
* Efficient paging and swapping to cassette tape at 300 baud.
Later versions will support multiple cassette recorders for really
high performance IO.
* Includes all Unix tools, networking and X. Full source included.
* Able to fully use all expanded and extended memory (i.e above
the 1.5K limit)
* Includes software to emulate a PC running MSDOS (similar to VPIX
and DOS MERGE).
* Support for Hyperchannel Interface (enables CRAY to be used as
a frontend)
* Support for real time processes.

We've been beta testing ZUNIX for the past year, using 150 developers,
all going through the edit-compile-link cycle all day. The only performance degradation we've noticed is when Jeff (the ZX81 is on his desk) has
to swap cassette tapes. Even this will be fixed when we write the
drivers for multiple cassette recorders. Can't wait!!

ZUNIX is expected to sell in the $1.50 -> $2.00 range, on a single cassette tape, from <J>oint <O>perational <K>ode <E>ngineering. Even after ZUNIX
has been fully implemented we anticipate there will be (as you can
imagine) a large amount of the 1.5K main memory free. To this end we
invite you to post your suggestions for further features that could
be implemented in the remaining space (eg traffic control system for
large city).

Didn't DR-DOS become Caldera DOS and then FreeDOS? Not sure.

The history of DR DOS is more or less like this:
- First, it came from Digital Research (DRI), up to version 6.0
- Then, Novell bought DRI and continued selling DR DOS 6

And, as soon as the ink was dry, Novell sued Microsoft, again.

The 90s were a weird parallelogram of hate - between Steve Jobs, Scott McNealy, Bill Gates and Ray Noorda, sometimes acting more out of spite than anything else.

My thinking right now is that the ascendancy of MS-DOS really
overshadowed any enhancements of CP/M. Like any technology, you have companies who made the investment in that technology and don't want to spend the money to change that, so they create a demand for updates to
the "old" technology. For a while, at least.

I recall that both Apple and the original IBM PC had the ability with add-on hardware to run CP/M machines, as there were quite a few machines in
business running CP/M, and having the "next" platform be able to run the old programs was a good move.

IBM won that battle, you don't see any Apple IIIs around anymore. :)

"Concurrent CP/M" is still from Digital Research, as I've read on Wikipedia (.de), Concurrent CP/M-86 is a later version of MP/M-86 + CP/M-86.

I remember some of the odd-ball mini-multi-user systems out there. There was
a PICK system that ran on a 386 and supported a handful of terminals,
although I don't know how fast it would be.

PICK was a multi-user virtualized OS that was a database with an OS and a procedural BASIC and primitive SQL query language wrapped around it. Great little system that ran on anything from a single-user app to the aforementioned 386es to midrange computers in the '90s.

the next evolution would've been the IIe... when the extended 80 col card arrives its got a little more going for it. But your point is still valid IBM or more accurately the PC based system became ubiquitous.

Yup. Apple had a Z80 card. The Commodore 128 had an expansion cartridge with a Z80 and the ability to run CP/M.

The company that Microsoft purchased what would become MS-DOS 1.0 from had a business of doing those kinds of add ons.

The original IBM-PC, though, was a little different. Unlike the 6502-based computers, it wasn't going to use a Z80 add on card. They were porting CP/M to the 8086/8066 family. It wouldn't run the Z80 software, but it would be really easy for software companies to port their software over.

Just to add something here:
There was(is) a program called BOOTOS2, written by an IBM employee,
which could create bootable floppies for OS/2.

And using this tool, it worked with only 2 floppies (instead of 3).
I've used it back in the day to create boot floppies which also

Novell had a tendancy of buying up products only to sell them off (or kill them off) later.

Sad, but probably true...

Didn't Novell buy up the Borland stuff and try to make an Office package out of them? DOS-era, so a little off topic.

There was "Novell PerfectOffice" which contained eg. WordPerfect.

AFAIK, there was a server product for WordPerfect, which was the base
for Novell's later groupware, GroupWise.

I don't know why, but my memories of Caldera were always of a slimy company. No evidence. It was just a feeling I always had.

That might be true. I fail to remember which company was/is the one
which became the infamous SCO (which sued IBM for Linux), but I think
it was one of the Caldera companies.

Besides, the best thing Caldera did was releasing most Digital

But there also were others who created Z80 cards for the Apple ][.

There were two schools of Z80 for Apple II. Cards like the SoftCard make up about 99% of them, and are essentially processor only cards, relying fully on the resources of the system. This limited the card speed to 1Mhz because
thats what all the system resources are running at.

The alternative was more a system on a card, PCPI Applicard, I think there
were two other brands on the same card. Which run at some ~6Mhz Z80 and
support their own 64-128k RAM on board, with possible RAM expansion.

Personally I prefer the latter, as the on board RAM can also be accessed from the 6502 side of life.

A lot of "old" Apple II+ systems were only 40 col, and for the most part

rendering issues due to limited processor speed.

well (as they were mostly 80) and even though there were a few Atari 8

Well, at that time, there was only the Commodore PET and Apple II. I know the PET was 40 columns (the 80 column models didn't come out until much later). I'm not sure about the Apple, but I'm pretty sure it was 40 colums as well.

That is I s'pose pretty true. Apple's would've come out of the factory
40cols at that stage of their lives... most 80col cards I can find are ~1981.. the odd one as far back as 1979 but you can imagine they would've been hideously expensive at the time.

I didn't really have much to do with them until about 1984 or so and pretty much everything was 80 by then.. the II would've been obsolete in favour of
the IIe which came with the 80col pre installed.

With the exception of a couple default files, which you can easily edit, Synchronet does a really nice job at displaying things for me at 40 columns.
I connect into the BBS with 40 column ASCII from the Atari and 40 column PETSCII (yes, it converts all the ANSI to PETSCII!) from the C64 pretty
often. It's really cool how you could almost think it was a C64 BBS. If you'd like to see an example, try tacopronto.bbs.io. For regular ANSI and ASCII,
use port 23. For PETSCII use port 2064 for 40 columns and 2128 for 80 columns.

It's just the login screen that is in 80 columns.
