I reconstructed this computer from board scans and schematics found in an Italian magazine from the '80s.

I fixed some of its design flaws and patched its ROMs.

I designed a keyboard for it.

I soldered every single PCB you see connected to it (and the mainboard too).

All so that I could use it to telnet into a #BBS without using the PC I have 50cms on the right.

I'm a totally stable person.

@hkz Disappointed you didn't build a CRT display...

@mike @hkz behind me, in my pending/soon projects are Fred Konapaska’s XY vector kit and some enameled wire. All the weird pointlessness of 8-bit computing, but at kV voltages!!!

@InkomTech @mike oh, this I don't know about, will look it up!

Step 1: take a retro CRT. Not a trini or similar.
Step 2: Replace the raster coils with custom ones. Get zigzag and uppy-downy near each other. *
Step 3: circuits to control high voltages for these. *
Step 4: turn x/y/brightness commands into defined movements. *
Use for Asteroids, Tempest, spacewar, etc.
