#pat80 — Public Fediverse posts

Also, I tagged all the old posts with the #Pat80 hashtag, so if anyone is curious to know what the heck I'm trying to build, clicking on it should help 😅

Fiddling again with #Pat80 , my #homebrew #z80 #computer. I decided to leave alone the composite video card for the moment, and use a simpler #character #lcd. I'm testing a 40x4 lcd based on a #HD44780 clone.

I tried to assess the situation of the #Pat80 #Z80 #homebrew #computer (https://git.ichibi.eu/penguin86/pato-z80-home-computer)
A computer to be useful should be able to:
- load a program and/or data
- execute the program on the data
- present the resulting data
It already does all that, but in a very janky way: its only way to input/output stuff is via a temporary terminal interface I made with an Arduino directly hooked to a IO port. [continues]

Progress!
I've got a basic #emulator working for my #Pat80 #homebrew #zilog #z80 #computer !
This should ease the os development as I can test the changes without having to: remove the #eeprom from the computer (without bending the pins), program it in the #TL866 programmer, place it again on the computer (aligning pins correctly), test, notice it's not working and have no idea why, start debugging with the logic probe on the #address and #data pins, swear in arcane languages... 😅

I'd like to resume my #zilog #z80 based #homebrew #computer project, the " #Pat80 ":
https://git.ichibi.eu/penguin86/pato-z80-home-computer/src/branch/c-emulator

When I left it, some years ago, I had no idea what I was doing.

Now, I have absolutely no idea what I am doing AND I don't remember where I left, but apparently I've written a decent enough documentation...

Anyway, apparently I decided the old python #emulator was too janky and started writing a new one in C, language i do not know and never use.

This will be fun 😅
