Anyone use a CP/M machine for BBSing? What terminal program do you use?
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.

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

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.

You'd need to use a line editor to post messages - that I don't want to
go back to!
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 remember that old Fido BBSes could run without screen controls, just printing to the screen like it was a "glass TTY", as they called it back then.

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.
That's just MS-DOS 1.0. 8)
That's just MS-DOS 1.0. 8)
But didn't CP/M support multiuser, kind of like UNIX did? It's
been about 30 years since I touched a CP/M machine, so I might be
confused lol

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.

Ha! Sometimes running very old OS versions is like being a sucker for punishment. :p
It would be fun to have a collection of x86 DOSes in the box with disk/manuals.
Didn't DR-DOS become Caldera DOS and then FreeDOS? Not sure.

There was MP/M, the multi-user CP/M OS. It supported different users
on terminals on a Z80.
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.
Everything's on line today. No disks and manuals, but disk images and
PDF files of the original manuals.
floppies are getting harder and harder to locate (especially the 5.25" floppies).
Otto Reverse wrote to Dr. What <=-
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).
That's because people like me are hoarding them.

Ooo.. I forgot about that. Do you happen to know how widespread MP/M
got? I've never actually seen a computer that ran it.
And there was Concurrent CP/M on x86, I guess it also supported
virtual terminals and multitasking.
I've started looking into CP/M-86, but I didn't know that Concurrent made their own version. Intersting. Something more for me to research.
But the bare CP/M did not support multitasking, neither on Z80 nor on
x86.
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".

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.
The history of DR DOS is more or less like this:

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.
acn wrote to Dr. What <=-
Sorry, I don't have numbers or more information on that.
Have a look at the Z80 scene, eg. in the Google Group "retro-comp" :) There, some people are running MP/M on some machines.
"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.
Don't underestimate the Z80 :)

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
- The next version was Novell DOS 7
- Then, Novell sold everything DRI to Caldera
- Caldera brought Caldera OpenDOS 7.01, which was free for home users
- Then, Caldera offered Caldera DR-DOS 7.02 and 7.03
- Afterwards, DR DOS came to "Caldera Thin Clients", which became
"Lineo", then to Canopy Group, then to DeviceLogics - which became
DRDOS, Inc.
- DR-DOS 8 came out in 2004, 8.1 in 2005; both disappeared because of copyright problems (stolen programs from FreeDOS)

I have that problem sometimes but I want to get a bulk eraser as I

Thanks Anna, I wasn't aware of Novell's part in its history nor the

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

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.

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.
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.
Ron Lauzon wrote to Otto Reverse <=-
Novell never really came up with a good direction for itself when the network side went away. They seemed to go in 100 different directions, trying many things and never really coming up with a really good
solution for anything.
Just grab a decent magnet, and give it a swirl... degaussing wand works nicely too :)

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

Yup. Apple had a Z80 card. The Commodore 128 had an expansion cartridge with a Z80 and the ability to run CP/M.
Novell had a tendancy of buying up products only to sell them off (or kill them off) later.

The Apple III was a strange bird anyway. I think is disappeared for

For the Apple ][, the "SoftCard" even was a product from Micro-Soft :)
But there also were others who created Z80 cards for the Apple ][.

There was an old computer "story" that went like this:
The Wizard of the Ivory Tower brought a box into the Master's office. "Here is a the new computer system that I invented," he said.
"Management has decreed that it shall be used as a platform for all new programs." "Wonderful!" the Master said. "I shall take it to the data center myself." Two weeks later...
"Where's the print out of my new program," asked the Wizard to the
Master. The master responded, "It's on the platform in the data
center."

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 think the main problem here is, that most BBS'es require 80 columns. Most of my retro computers supply 32, 40 or 64. That make it a subset
I can use for BBSing.
Most "modern" BBS would be 80cols when you're at ~40cols, have to admit having never seen a 64col display thats and odd one... Mostly you're
The TRS-80 Model I and III were 64 columns.
Interesting, I recall many fun and frustrating times playing Raaka-tu on
a model 1, wasn't mine... I have to admit not counting the columns...
but I thought it had 80... even back then... shrug.. there we go, you
can still learn something new every other day :)
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.
