Running CP/M on the Tandy Model 100!

- In this video, I'll be going through the process I used to run CP/M on my Tandy Model 100 using the REXCPM chip. CP/M is an early operating system that was popular in the 1970s and 1980s, and the Tandy Model 100 was a popular portable computer from the same era.
The REXCPM chip is a modern add-on that allows you to run CP/M on the M100. I'll be walking you through the process of installing and loading the firmware onto the REXCPM chip, and then show you how to load and run CP/M.

Great to see there is an active community around these!
I had one when I was .. 14? maybe? I remember typing in some BASIC and saving/loading from cassette. Simple usable machine. IIRC journalists of the day liked the full travel keyboard and could file their copy down a phone line. But wow, sluggish by today's standards! We must've been more patient back in the day. :-)
Great video! Glad you popped across my feed today. Subscribed!
Awesome! Thank you!
Thank you for making this video. I've been looking at this for a while, but there hasn't been any videos about it. Subbed.
Thanks! The M100 community is pretty active, so definitely hop on the mailing list if you’re interested in these devices. There’s lots of really sharp people on there.
Excellent video...Thanks!
I remember running CP/M on my Amstrad NC100. It has a similar form factor to the Tandy, but doesn't require hardware hacks, since it uses a Z80 CPU. All you need is an SRAM card.
Very nice - I’ve had a couple of people mention that I should check out some of the early Amstrads, so perhaps one of these days 😁
Awesome channel !!
So I have the Olivetti M10 - should be the same - so I think I'll have to try this also ... CP/M 4 ever ;-)
Thank you for sharing this video 👍
Very nice - the M10 is on my list to collect. I don’t think the REXCPM chip is compatible with the M10, but it would be worth reaching out to Steve Adolph on the ordering page and finding out. Good luck!
Anyway the form factor is perfect for mobile computing: real keyboard, 80 cols x 10 lines display (graphic would be ok), terminal / Xterminal & linux, THAT would be my computer on the go!
Sorry, I missed which system you’re referring to
So CPM would not run on a regular REX? You need to buy another chip? It looks great but if you forked already 40 dollars for the regular REX, you need another 60 dollars to get CPM running on the device, and that seems to be quite a bummer sadly.
That's correct - you need the SRAM chip that's on the REXCPM
How much is this worth?
