Amazingly I have the cables, I will need to borrow a SGI or similar display as the VR241 I attempted was not able to synch with the display controller. I even have an old dirty mouse that should work with it.">... [ read more ]

I think we found the right place. My phone camera is only so-so at object photography, but I did get a few usable photos. Next time I visit I plan to bring a good camera and include photos of the equally-wonderful 2nd floor, not pictured in this set. Click image for larger view.

MicroVAX 3100 with Storage Expansion
Pictured here is a 1988 (?) Digital MicroVAX 3100 with Storage Expansion boxes. The model number of the 3100 is DV-31BT4-A-A01 which I believe makes it a 3100 model 30. The storage expansion boxes are basically external SCSI hard drives. Their model numbers are DV-31BT4-A-A01(middle) and SZ123-XA (bottom). Click image for larger view.

Can you guess the username and password? I could on the 2nd try. A password as boring as the box. Click image for larger view.
Somewhere along the line DEC stopped trying to make interesting boxes, externally at least. Actually the 4000-60 is a pretty advanced computer, much more powerful than an average PC from 1991. This box would have been pretty expensive too. Click image for larger view.

Commodore B500 B Series
The ever stylish Commodore B500. Click image for larger view.
Before the C-64, Commodore put out a few computers containing SID sound chips. The first was the P500 which was followed by the equally rare B500 model. For reasons unknown to me, just before going into full-scale production Commodore renamed the B500 "B-128", making the original nameplate version very rare. The name change occurred before even the manuals were printed. I don't know exactly how many were sold, the serial number is probably not directly connected to the production number of the machine. Other than the ROM version and perhaps the power supply the B500 and B128-80 are virtually identical. NOTE: The No">... [ read more ]

The Magnavox Odyssey2 computer video console running Computer Intro! cart
The 1978 Magnavox Odyssey2 computer video console running Computer Intro! program. The Odyssey2 had an Intel 4048 (MSC-48 microcontroller) CPU and full membrane keyboard making it a "computerette" (my term) when compared with its market rivals the Atari 2600 and Mattel Intellivision. Computer Intro! allowed the user to create and run 4048 assembly programs, although I am not aware of any way to save these programs. There was no cassette storage that I know of.

PiDP8 2015 Model
This is the 2015 version with the little dots on the white switches. I think I placed the first or second paid order, shipped in July of 2015, but I finally got around to building the kit over the 2016 Christmas holiday. These kinds of projects I like to save for the right moment, a very enjoyable kit. Hats off to Oscar Vermeulen for his fine work designing both the kit and the software. Click image for larger view.
