Using a Propeller alongside the Z80 has an extra advantage, you never have to worry about overheating.

Fantastic!!! I believe that this is the best Z80 project!

Aiden, I see you ported my version of TB. I dig it. I look forward to seeing additional videos.

@@AidanJennings you’re quite welcome. That’s what it’s there for. ;)

I would of like a more vanilla approach and use just the Z80 without the propeller. Great work though.

use maxtrix like 8 x 8 using a mux you can get banks of memory to use

I post updates on twitter twitter.com/AidanJennings19/status/1545882286675066885 I'll make a video once the board is fully assembled and debugged

Has anyone created tutorials of writing your own BASIC ROM from scratch?

Not that I know of, but Doug Gabbard (aka Retro-Depot) translated the original TinyBasic to Z80 asm. kzfaq.info/get/bejne/oqlhgZCpya-XlH0.htmlsi=1hmmOjHFYZ0xfVXC github.com/Obijuan/Z80-FPGA/blob/master/Tinybasic/Basic.asm I did not write my own basic implementation, all the ones I show in these videos were written by someone else.

WHY don't you use the eZ80 chip, which contains sooo much stuff already, and can get to pipelining 50Mhz, and many other things? That should result in LESS parts on the board, and would give new opportunities, with much larger memory etc. etc. :

The scope of this project was really just to run CP/M and maybe Fuzix. I considered it early on but the eZ80 is a considerably more complicated chip than the Z84C00. It was my understanding that the eZ80 'core' has a few differences from the stock Z80 that could have made it more difficult to get some software running. At the time I also didn't have the tools on hand to reliably assemble a board with SMD components. In the future I plan to do a fully/mostly SMD version of the Tom80 with an all-in-one chip, probably using a Z180 or Z84C15.
