  Large Apple III Collection by Bill Degnan - 08/19/2010 14:23
The Apple III Plus Computer. This unit is configured to use three drives.


I received a very large collection of Apple III computers and related items including docs and software from David Otalini. I have only begun to work through the 20 or so boxes of docs, parts, software, and newsletters. In the mean time, here are some photos.

  Replaced motherboard and keyboard light by Bill Degnan - 10/29/2010 15:50
Replaced the motherboard and the keyboard light bulb. The system now has only 128K, but it's back to stock configuration and it works. Nice and clean too.


Apple III 512K On Three RAM board


I put the motherboard with the 512K add on RAM board (pictured above) into a parts system that has no power supply.

Typical directory from a Apple /// system disk.


Both of these drives are now functional after replacing blown "rifa" capacitors.
