A Mac System 7.5 dialog box from ResEdit with a small pig icon, the text "Start pig-mode?" and Cancel and OK buttons. It apparently constantly tries to free up resources, aiding developers. To see it, hold command-option-shift and choose About ResEdit from the Apple Menu.

A tiny pen plotter housed in three increasingly sized plastic boxes of red, blue, and yellow. A white top with buttons and paper coming out show the text Hello, World and a differential growth pattern drawn on it.

Over the past week, I built a new tiny #PenPlotter with a vintage ALPS 2.25" mechanism! It sports a 3D printed snap-fit case, receipt paper holder, speaks GRBL over WiFi, 18650 battery w USB-C recharge, and a color scheme borrowed from the JLPGA PowerBook 170.

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.

An Atari Portfolio running Zork 1. On the monochrome screen it says "West of House. You are standing in an open field west of a white house, with a boarded front door. There is a small mailbox here." There's a > prompt and a flashing cursor at the bottom of the screen.

Logic probe or scope and see if thereโ€™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. Iโ€™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.

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.

This is a Sony Anycast Station AWS-G500HD from 2007. It's essentially a Sony luggable PIII 933Mhz PC that runs Linux 2.4.20 with a ton of FPGAs to do the heavy lifting of a video switcher. Plus glorious physical buttons, faders, dials, and removable keyboard. And a jog wheel.

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.
