Updated: [ ADM3 Working (always has been) ] 12/19/2008
Restoration project notes for Lear Siegler ADM 3A terminal S/N 21818 from late 1977. The bad news: I cannot communicate with a known-working computer, no response from keyboard although box prompt is present. The good news: The picture is in good shape. I cannot get the computer to respond locally either. I tried to jumper pins 2 and 3 (I believe those are the ones). Missing the dip switch cover. Updates to come. Pictures ADM3A">... [ read more ]

Archiving Apple II disks

Test subject: Apple II GS with 3.5 and 5 1/4" drives, ADT 1.21 and a bunch of diskettes.
Apple II GS Computer running ADT 1.21
I decided it was time to learn how to archive Apple II disks by copying them (somehow) to a modern computer. I chose an Apple II GS as the bridge system because it has a 3.5 and 5 1/4" disk drive, and it can read old Apple II diskettes. The question is how to take make disk images and save them to 3.5 disk, and then find a modern system to read the 3.5 disks. Finally I will need to be able to both run the disk images in an Apple II emulator, and also move disk images from other sources to the Apple II GS for extraction onto 5 1/4" in Apple DOS 3.3 format for use on an Apple II (II-->IIe).

Updated: [ re:TM 990/189 or PP189 ] 10/21/2008
Hello to all, I get a TM 990/189 System from one of my friends. The interesting point is that the system is build in a black box. You can detach the cover from it. On the cove there are the letters PP189 and of course the Texas Instruments brand name. I searched in the internet to get more information about this system. I found some of the PCB (TM 990/189) itself but nothing about the box. Do anyone know more about it? Regards from Germany Andreas">... [ read more ]
