A rather beat up SE turned up on Marketplace and I noticed it has an unusual card in the PDS slot. It looks like an IEEE 1284 Centronics port, like for a parallel printer, but I'm not aware of any parallel printer cards for the SE. Any idea what it might be? Is it worth picking up this SE...

I lifted up the cable and found a good clue. It says Pro Micron. So it looks like it's an Arduino board very similar to the link below, but minus the USB header. (you can even see the white outline for a USB header on the PCB)...

I have two of these ADB dongles and I have no idea what they do. Since there are no other ports on the dongle, I'm guessing it's a form of copy protection, but does anybody know for what application? Both of the dongles are cracked open like this. The only text I can read on the plastic says...

Ding! Ding! Ding! We have a winner. Thank you for conclusively solving this mystery!

Thank you all for your feedback and suggestions, especially Mac84's detailed description of KyroFlux & AppleSauce. It sounds like I'd be better off with AppleSauce, except that there aren't any available right now. For now, I'll continue inventorying everything and maybe if I'm lucky there...

I'm willing to invest in AppleSauce or KryoFlux but will need some more recommendations on which. Naturally both claim to be the ultimate in imagers. My quick research seemed to point towards AppleSauce, but KryoFlux does have one big advantage: it's actually available for purchase right now...

I have just acquired a truly massive collection of vintage Mac software from a collector who recently passed away. I will post more details about it later as I inventory the collection but there is a tremendous amount of fully boxed Mac software, with a particular emphasis on the 1984-1993 era...

The second option, where you enable the cassette mode later runs a real risk of getting your developer account banned if you get caught. Basically, what happened to Epic. If you have other published apps or are making money off apps, that's a lot of risk, unless you published it under a...

I don't think you'd cause any trouble for the asciiexpress.net site but there's an approximately 0.00% chance that Apple would approve the app. (Actually, I'm probably overstating the odds a bit.) You *might* be able to get it approved as a generic transfer app that let you play files from...

Yes, please share your BOM for caps on a 1.8A Lisa PS. I've got one that's due for a recap.

@slomacuser Unfortunately the boot drive was dead so no interesting software that might offer some clues. One of the external data drives reveled that the original owner worked for a large Apple reseller. (There was a lot of sales data from 1989-1996 that I'll comb through some day but that's...

I found this guy in a Mac IIci I picked up at an estate sale. The two DSP16A chips give it away as a Photoshop accelerator, but who is the manufacturer? It's not a ThunderStorm or a Daystar Charger. The design is very similar to these cards but there are no SuperMac or Daystar markings and...

This was literally the very first thread I visited here on Tinker different and I have a new project. This place is going to be dangerous to my free time and wallet. But thanks for the awesome idea!
