Quote from: MicroNut on May 07, 2026, 07:28 AMI got 2 replacement keyboards from Sell My Retro in the UK Keyboard. They are made of stronger, longer lasting material. They have the UK symbols "Rub Out" rather than "Delete" and "New Line" rather than "Enter". They are easy to replace and work well.

Wow! At $10 for the keyboard, and about $5 for shipping (from the USA,) this is a darned good deal for a TS-1000.

Yaeah. Not bad at all.

Okay, PM me your address so I can send you a 62256 SRAM IC (24-pin DIP).

The memory isn't what it used to be, but in my mind, if we can simply get CP/M running on the hardware, could we not just use a Z80 assembler designed for CP/M? Again, we may have addressed this before. But I still have the hardware sitting aside for the original project.

I got it!! Lil bit o tweaking with signal input and output wires and I got a signal, and the keyboard is needing fixed.

Great! Big advance - now to get the keyboard fixed, and the 32K upgrade and you are set to go.

Yup, I'm going to try the keyboard from the other unit n see if that works.

Thanks. I got a one from another unit I can try first. Wish I could get one like this https://www.ginger-electronic.com/en/retro-computer/24-40-zx8-kdlx-keyboard-for-sinclair-zx81-and-zx80.html#/26-model-zx81

Great news! It's time for some Z80 assembly work now!

Got it, okay.

It is looking like the .dsk files on Udo's Github may be bad. The simulator program itself seems to be working, but it won't let me boot - I keep getting an error and it shuts down. I saw a video of this running on a regular Pico, and when he loads the disk file, and then boots, it come up in CP/M.


I'll keep looking into it - it will be a cheaper, easier way to get started in CP/M. And, if I can get a decent .dsk file created we can use this for the learning Z-80 assembly programming.

That said, the development work in getting RunCPM going on the plain Pico is really simple, and even easier on the PicoCalc. I also like the idea of running the disk straight from the SD card, rather than the .dsk image file. It's just the development work to get it going on the RP2040-GEEK that is turning into a bear.

Quote from: MicroNut on May 06, 2026, 12:11 PMI got an adapter for the TV Out for my ZX81 as well. I really had to fiddle around with the pots to get the display working. The version I got also created two large vertical black bars in the border section. I ended up using a portable 7" black and White TV circ 1980, I picked up at a Salvation Army store, which worked with the TV out instead. So you may have to fiddle around with the pots.

Yeah, I outta find my small old lcd screen to try it on... might be my tv as well.
