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 ]

Updated: [ 1969 CTC Datapoint 3300 Ad ] 05/06/2013
The Computer Terminal Corp. DataPoint 3300 after cosmetic restoration work completed. This is the first glass terminal first produced by CTC in 1969 (after being announced in 1967). The 3300 was a play on the ASR 33, which is what this machine was designed to replace. The serial number sticker says 1030. Click image for larger view.
System after cleaning. The terminal was in pretty bad shape (evidence of rodents on the keyboard), but fortunately there was no rodent nests inside. First, the cover was removed and">... [ read more ]

A useful NTSC Commodore Plus/4?

by billdeg
Total messages in this thread: 1
A complete Commodore Plus/4 system with CM-141 display, joystick, box/manuals, and a 10-box set of software.
When you buy a Plus/4 system from Ebay, expect the "CPU" chip, the 8501R1 (or 7501R1), to be dead. The classic symptom will be a pattern of small orange horizontal dashes on the screen, and a failure to initialize into BASIC. I was fortunate to find a source for these chips, no longer available by the way, and fix the system you see here. The next obstacle one must overcome to making your Plus/4 system useful is to find software. Most of the Plus/4 software was written for the PAL version, and very little will work on an NTSC system. I have searched extensively and collected the "best of" programs for NT">... [ read more ]
