At Kennett Classic we have a complete (or near complete) run of MICRO journals. These along with a whole lot more will be available in our library room by the end of the summer. MICRO first appeared in 1977 and it caters to the Apple, AIM, SYM, KIM, Atari, OSI and PET developer. In their own words, MICRO is "the technical reference journal which reports monthly on the development and practical abd theoretical application of new 6502 microcomputer technology"">...

Amiga 1000 Engineering Sample

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.

Updated: [ DERAMP PC2FLOP ] 02/11/2021
Pictured is the test system set up to explore the functional status of this iCOM 3712-58 dual 8" drive. Click image for larger view.
Referring to a 2006 post I made on a vc forum, Mike Douglas ("DERAMP") contacted me to see where things stood with the project. He had a similar drive. I had not done anything with the drive since 2006. But had I known that I had the correct s-100 interface card for the drive, i would have tried sooner. Mike sent images of the interface cards that work with the iCom. I checked my inventory to finally match an unidentified controller to its peripheral. It was also fortunate that drive had an Altair-compatible CP/M . AND! I picked up along the way the schematics for the drive. I finally had everything to take a">... [ read more ]

Updated: [ NOTES / Repairs ] 02/05/2021
The International Microsystems (IMI) IM 1010 PROM Programmer has an Intel 4040 microprocessor. Pictured is the programmer with the 2708 / 2716 pod option inserted. These pods can be removed and replaced as needed. The system has both Burroughs Panaplex display and serial output, one can switch between them. Click image for larger view.
I have a lot of notes and the schematics. The programmer was donated in a non-working state but I am hoping we can get it rolling again. This programmer has pods that can handle 2708, 2716, 2716-1V, 2732, 2758, 2532. I am unfamiliar with TIGEN 1 and IM ROSI, but these labels appear as options (ROSI RAM/EMULATE/PROM).">...

It's always a good idea to crack open a system every so often to test and make sure it's still in operational order. This 520 ST is currently on display at Kennett Classic in the "16-bit" room for visitors to try it out. Click image for larger view.

1966 SDS SIGMA 7 nameplate and manual. This was among the earliest 32-bit computers sold. Click image for larger view.
Cover removed from a Teletype Model ASR 33. This machine is configured to communicate with an Scientific Data Systems "SDS" Sigma 7, which dates it at about 1966 or so. In 1970 SDS put out their confusingly-named SDS SIGMA 6 which included a lot of the optional items found in the 7, standard. Xerox later bought SDS and renamed everything with an "SDS" to XDS.
