MacWorld Macintosh

I was cleaning up the basement and ran across this Macintosh. I can't find any documentation on it -- so I am going to try and make some educated guesses on the specifications.

Built-in B&W display. One floppy drive (non functioning. jammed?). Pre-ADB keyboard. No arrow keys. I must have lost the mouse.

Plastic intact. Must be earlier than Spindler era. Needs retrobright, though.

Opening it up. No fan or expansion slots. So, I am coming to the conclusion this was a Jobs design.

I removed the motherboard. Fortunately, no exploded batteries or leaking capacitors (but I am unable to find an OS-CON aluminum polymer replacement yet).

32 kHz processor. Likely 68HC000 for lower power?

I noticed a little bit of corrosion. Isopropyl followed by ultrasonic should clean that up.

One note. When replacing the AG3 CUDA/PRAM battery, be sure that one of the battery clips touches the side. If it gets bent down then the computer will not boot up -- similar to the LC 475.

I think you can skip the retro brite 🙂

Check out that ortholinear keyboard! The industrial design group were way ahead of the curve.

One day in the future, a digital archaeologist is going to stumble upon this thread and be totally confused. 😀
