Thank you for liking and following my #PERSEUS-8 homemade 6502 computer & #6802 Serial Terminal. Now, I'm working on a floating point interpreter for my computer PERSEUS-8. I've got the four arithmetic operations, the editor, and the program line analysis and execution part almost working.

Hi, thanks for the like/follow my Grant Searle's CP/M. I have a spare board I am happy to post if your interested (free).

I note your looking at a front panel. You may like my Weird CPU. It has a tactile switch front panel, but controlled by the CPU. It is really not that hard to write some firmware to load/store binary with your custom CPU using this style of panel.

In my case data is read when ever the the address changes and written if the data changes.

The program (which starts at 0x80) is executed if you try to write to 0xFF (the top of address space where the registers live).

Regards Alan
