Lovely piece of digital archaeology. Reverse-engineering a Classic Mac era device is equal parts patience and respect for old constraints. What stood out to me is how much implicit knowledge was baked into drivers back then, timing assumptions, undocumented commands, “it just works on System 7”. Also a good reminder that long-term hardware usability often survives only because someone is curious enough to poke at it with a hex editor instead of letting it die in a landfill.

> The official Epson TWAIN driver exists, but it’s a complex plugin designed for Photoshop

I remember there were free TWAIN hosts that allowed you to use scanner plugins without Photoshop. Could be worth a look.

It is supported by vueScan (of course), but Classic Mac doesn't.

Film photography revival goes full swing, I hope there will be new good film scanners with MF format support. Nikon CoolScan 9000 costs unreasonable money, if you factor in lamp which can burn-out and overall age of the machine. And drivers are pain in the ass on modern systems, though, again, vueScan supports it. But ICE (dust removal) works better in Nikon software.

I love all of these stories of writing new software for Classic Macs. There is something really special about maintaining the usefulness of an old tool that most people have forgotten. Farmers who restore and run vintage tractors know this feeling well. They have built communities around this intersection of hobby and real work.

I have a Mac Classic given to me by my uncle. Last I checked (a few years ago) it booted up just fine. I need to crack it open before trying again because I’m afraid of leaky caps or batteries. Just need to find the time.

(This is 90s tech, but it's still Classic Mac.)

In the late 80s as a kid I sometimes came across the Swedish version of Macworld.

Unlike the US original edition I think they mostly catered to people working in print layout/DTP. They were casually reviewing all kinds of exciting things costing like $10-50k in today's money. Things like flatbad scanners were super expensive. The concept of 24-bit color was strangely exciting, seemingly bordering on alien tech.

It was like a different world compared to the kind of home computing HW I was using. Even the magazine was a lot more beautiful than anything else I had seen.

That Minolta is gorgeous looking.
