Yea - I'm hoping to add a extra usb port by populating one of the unused sockets and putting a preloaded low profile USB stick inside.
We'll see how it goes.
Have a look at this -

can be completely self contained CPM over serial terminal.
This is where I cut my Z80/CPM teeth.
Thank you
It's an example pic I grabbed, mine has a Power supply and the CRT, it comes down to 2 pins so I'm sure I can work it out, LOL. The case was gutted back in the 80's I found it in a company I was at in the early 90's. I do have some modered 8088 type PCs and a video card that would work with it but if an Atari ATX were around. I'd jump at putting it on this with a nice LCD on top for the 1090/1091 80 column output.
It's good to see you around here - btw.
Thank you
I have IBM Portable Personal Computer 5155 model 68 "luggable" case with CRT that would make a nice setup. I will need to test the XEP80 with the Amber CRT in it. So if ATX happens I'm ready.
Thank you
I really want to see RS232 serial on the bus, we can then easily talk to a pi , pi zero, rp2040, and a CPM board, I'm strongly in favor of a Z80 CPM. I have also been toying with small informational OLED displays, again all over RS232.
Thank you
I would like to see Multi Serial card able to plug a raspberry pi into it, perhaps hat style so the pi could be terminaled to allow CLI control.
This might also be able to be a modern Z80/CPm emulator.
I really have been thinking for a few years of being able to hang a oled or epaper as a independent terminal to show cheat sheets based on state of the computer, for instance a list of Short Cuts for FujiNet or Sparta Dos
If it's Multi - serial you could add a Arduino As a Sdrive and Reprogram it on the fly.
Lots of things to do in this space. A trifecta of a Pi/Arduino/RP2040 makes a ton of possible features
