The HAL Communications Corp HAL DS2000 KSR smart terminal. Click on image for larger view.
The manual refers to this BMC monitor, so I assume it was purchased along with the KSR unit. Click on image for larger view.
Here is a nice big pic of the boards and wiring view, with the case open. Click on image for larger view.
More pics What's next? Attach it to a computer expecting a current loop as if the HAL were a Teletype. There is also Morse code and Baudout communications.">... [ read more ]

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.

Beckman Instruments, Inc. made a connected industrial research computer system called the DEXTIR, which was designed for to prepare data for computer entry. The model pictured in this photo was installed at the ESSO Research Labs in Baton Rouge, LA in July 1961. Click image for larger view.
Beckman issued a proposal to GM some time after the above photo was taken for an automatic monitoring and control system for the Die Casting Department of the Guide Lamp Division at General Motors. The comptuer that the DEXTIR would feed its data was (I believe) a UNIVAC 1108 computer from the same era. Perhaps also an IBM 704, 709, 7090) Download it here To my knowledge there is nothing published about this machine.">... [ read 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).">...
