A duplex issue? If you have half-duplex set, the local computer echos what you type, and if the remote system also does so, you end up with duplicates. But that would duplicate everything, not just carriage returns. In Linux, the "newline" is just a carriage return. But under systems like...

What are you using as the connection to the BBS? If it's a Wifi modem, that would be a good place to look to see if there's some sort of translation setting.

I recently was able to pick up a working Sperry HT at a reasonable price and I've been renovating it. One of the interesting things I learned about it was that it included a real time clock (one of the first machines to have it included from the factory), but to use the real time clock, you...

https://archive.org/details/SperryHTServiceManual Long, 4 short means you forgot to plug the keyboard in. Long, 5 short means you have a bad video card - or maybe have the DIP switches set wrong (i.e. have Monochrome set when you have a CGA card). I don't remember if these supported EGA.

Here's the version from my system.

My Sperry HT (which is supported to be a Leading Edge Model M) has a program called ROMVER that prints the version of the ROM.

I have the Stupid PET tricks module (along with a SD2PET for "hard drive" support). I also have PETTerm. But while the keyboard of my 4032 is much nicer than the original "calculator" keyboards that the PET has, BBSing on it is not real fun. The keyboard layout is pretty bad for touch typing.

Already ordered 2. And I'm on the wait list for the next batch of CE-158X. I love playing with my PC-2s.

I used Edwin a lot back in the 2-disk-drive days. I liked it because it used the Turbo Pascal-like commands (Wordstar?) that I was familiar with and it was small and fast. Today, for my MS-DOS machines, I use Norton Edit.

It depends on what old hardware you have. For my MS-DOS systems with 3.5" floppy drives, I have a USB-to-3.5" floppy drive that I can use on my modern systems. For MS-DOS systems with hard drives, I use a IDE-to-CF adapter and the CF card just mounts to my modern system. For my TRS-80s, I have...

Most CP/M systems were designed similar to the way minicomputers were designed: A computer part, and a terminal part. The fact that they were often in the same box made people forget that. So what most of these systems lacked was a way to access screen memory since the screen memory was **not**...

But part of the problem is that Gary didn't have CP/M-86 when IBM needed it. The second part of the problem is that CP/M-86 is not compatible with CP/M-80, so owners would have to re-purchase all their software. So the choices were 1. Stick with the Z80 and CP/M-80, which was harder to do...

The TRS-80 line didn't like CP/M very well due to the memory layout (CP/M expected things to be in certain places and the TRS-80's didn't do that). I think we had to wait until the Model 4 came out to get CP/M. I know that I have a version that runs on my 4P.

Yup. Directories and price. Those are probably the two things that caused CP/M to go down. When the IBM-PC came out, the low end systems were supposed to be "boot to BASIC and use a cassette", but that era was already ending. Heck, even my high school had floppy drives for their Commodore...

One of the things that I've learned when doing a "deep dive" into any historical subject is that the concept of "era" only means "when X was dominant". There were many years where the old was still in wide use while the new was growing. So there's going to be the "era of CP/M" where CP/M was...
