Did you know the Amiga Kickstart boot screen is stored as vector data? It uses 412 bytes. 💾

It’s plain paper, not thermal so all good.

It's my Lisa Clone 😊

In my own research, I think it was simply a batch script that type'd two text files, pausing with "ask.com" in between. Ask uses the prompt "Strike any key when ready ..." which is seen in the movie.

Logic probe or scope and see if there’s a clock and the CPU is running code? Can you burn the original firmware that came with it back onto the ERPROMs?

Interesting. Your motherboard seems to be a different revision. I’ve only seen 5 EPROMs in a row and only 5 sockets.

Can you take a picture of the bottom where the firmware ROMs are located?

Have you tried verifying the EPROMs?

Does it work when you put the original EPROMs back in?

My #AppleLisaClone has a new front panel! I got one of the new Lisa 1+2 hybrid panels from Mac Effects, courtesy of @rectapete.bsky.social

I moved the iPad LCD panel over to it and added some custom 3D printed CRT bezel gap fillers to fit the curve.

I’ve got 7 of them right next to me

Lots of IO. Audio is all built in. Video inputs from 3 card slots. I have two SD cards and a PC/VGA card. There were also HD capable cards.

Each SD card has three 1394/400 ports: two for DV input and one for HD. You can playback or record PGM and both inputs from the card simultaneously as AVI/DV.

Interesting! I'm not sure how that would work since that seems like it would map things into different locations in memory unless its more clever than that. Look forward to you powering it up.

There is a battery— it’s the black rectangle that says Data Sentry. I removed the ones from mine, no leakage.
