1976 DATAC 1000 6502 Training Computer

by billdeg
Total messages in this thread: 1
The DATAC 1000 was designed by Philadelphia Area Computing Society (PACS) members Carmen DiCamillo and Roland James in 1976. In its original form the DATAC 1000 was a single board 6502 microcomputer trainer that included a training course for beginning computer engineering students to use to learn about 6502 microprocessor systems design. Click image for larger view.
It is likely the DATAC 1000 was demoed by PACS at the PC'76 personal computing consumer trade fair in Atlantic City, NJ, alongside the Apple, MITS, Processor Technologies and other pioneering vendors of the time (AUG 28-29 1976). PACS would also host instruction sessions internally that featured the DATAC 1000 and at least one local college (Drexel University) used them, possibly other schools as">... [ read more ]

This Commodore Amiga 1000 came from the engineering department and was owned by former CBM engineer David Diorio. Click for larger view.
This system is unique because it has no serial number or identification plate on the case, keyboard or mouse. The ROMS are v1.1 and the keyboard has the "bouncing ball" logo in the upper right corner. The power supply switch is backwards. Otherwise it appears to be a normal early Amiga 1000 with a memory expansion board. More pics">... [ read more ]

C64C dev motherboard with: PCB ASSY NO.250451PCB No. 251915 Rev.2 printed on it. The VIC chip is missing. Click image for larger view.
I don't see this board documented in the normal places and the PCB does not come up in a search. The VIC-II is missing. The board was originally owned by CBM engineer David Diorio and was donated to Kennett Classic when he unfortunately passed to the great motherboard in the sky recently. My initial guess is that it was a dev board from when the Commodore 64C was being crafted, or David was experimenting or modifying the design somehow. I have asked around to see if anyone knows more.
