Xerox 8010 Star

Updated: [ Xerox Star 8010 ] 02/27/2012
The XEROX model 8010 was known as the Xerox Star because that was the name of its application software. Before the Apple Lisa and Apple Macintosh, the "Star" is generally accepted to be the first stand-alone commercial computer to employ the graphical user interface / desktop metaphor. This particular system is missing the side panels, wheels, and is not fully operational. The notes to follow describe what steps have been taken to stabilize and hopefully restore this system. Aside from the ugliness of the exposed steel under carriage, the only real problem that I have detected so far is the Quantum Q 2040's drive belt, and possibly some bad RAM.

Updated: [ Xerox 820 disks compatible with 820-II? ] 02/26/2012
Hi - I just successfully created two boot disks for a Xerox 820 II. CP/M 2.2C. I have tested the process, works. Contact me if you're attempting to restore a Xerox system and need a boot disk. Copies are for restorative purposes only, only where permitted by law, educational use only, and so on. I have an extra manual as well, for a fair $$. I will put up pics of the system when I have the chance.">... [ read more ]

Replacement teletype print hammer head

If you've finally acquired a teletype for your vintage computer, you need to replace the rubber print hammer head because it will have disintegrated. It will feel like a gummy bear candy. The acknowldeged printer hammer head replacement for the Teletype model 33 is a PVC tube, fit over the hammer like a sheath, but I have found recently that these last less than 100 hours before a the tube needs to be replaced. A permanent divot will form on the tube where it strikes the cylinder, making it useless. So here is a tip - if you use your teletype regularly, replace the hammer pad each time you replace the printer ribbon. Here is my Teletype 101 primer - how to set up an ASR 33 for use with a computer. ">... [ read more ]

Radio-Electronics December 1956 with "Relay Moe" article by Edmund Berkeley describing one of the earliest electronic computer games ever produced. Click image for full article.
Occasionally the question of the first computer video game comes up. Here's one that must be one of the first. This analog computer-based game is capable of determining it's own moves. Relay Moe is not the first computerized tic-tac-toe game, I am guessing the first appeared in the early 1950's.">... [ read more ]

The first clue that this computer is no normal Franklin Ace1000 is the "UNITRON" message that displays when the computer first boots.
The Unitron motherboard is version 658 rev C. Note how it's much smaller than a Franklin motherboard. The Unitron 658 is sized to fit i">... [ read more ]
