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 ]

The manuals supplied by Commodore are frustratingly incomplete and require a lot of head banging and experimenting to accomplish what should be simple tasks. The top of the klugey list is printing a program listing. Here are some useful tips and tricks including a few things that are not found in the original manuals. I still recommend that you try to find and read a copy of the SuperPET manuals (pamplets) too. 1. In order to use the SuperPET in 6809 mode, you must have the OS boot disk titled "SuperPet WCS" present in drive 1 (left drive) of an 8050 (or 8250) dual-diskette drive. Set the side dip switches to 6809 and R/W. If you do not have this disk or a 8050/8250 drive, you'll have to trouble doing much more than staring at the initial boot menu. This menu lists the programming language options (Pascal, COBOL, FORTRAN, BASIC, etc.) BUT these components are not included in... [ read more ]

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).

In preparation for class demonstration of the Apple Lisa 2/10 I took some new photographs. Minor repairs were needed. I had to take apart the keyboard because the space bar had dislodged from the little clips that hold it in place. I also replaced the MAC mouse with an original Lisa mouse. Note the new pictures have the original mouse.... [ read more ]
