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 ]

Large-Scale Systems Museum (phone pics)by billdeg Total messages in this thread: 1  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.

Digitial MicroVAX 3100 30 Systemby billdeg Total messages in this thread: 21 Updated: [ Conclusion ] 10/20/2017  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.
 So far I have not done much other than boot the system from the console and run a SHOW DEV command to see what the VMS/VMB assignments are. The system is runnin">... [ read more ]

VAXstation 4000-60by billdeg Total messages in this thread: 1  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.

 So far so good I can establish communications. Note the lower-case characters. ">... [ read more ]

Commodore CBM B500 (US / NTSC)by billdeg Total messages in this thread: 1  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 ]

Magnavox Odyssey2 1978by billdeg Total messages in this thread: 1  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.

Raspberry Pi PiDP8 Emulator rev 2015by billdeg Total messages in this thread: 2 Updated: [ Further refinements ] 08/18/2017  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.
 I chose the Pi Zero because it can feed off a USB port for power. There are just enough ports to connect">... [ read more ]

Another CBM D9090by billdeg Total messages in this thread: 3 Updated: [ Tandon 603s Replaced by ST241 ] 08/17/2017 I have a second CBM D9090 ROM A, to test, and see if I can get it up and running. It's totally stock, other than the fact that the cover is missing. My other D9090 is a ROM C I think. Pics">... [ read more ] |
VCFed August Workshopby billdeg Total messages in this thread: 1  old terminals had style, eh? This terminal has the lower case ROM and switch cover. Pictured here the screen shows it while connected to the Internet (telnet Level 29 BBS). Note how the font is vertically justified; the lower case characters have to sit centered along a plane so that characters like the lower-case g are raised up. click for larger view.
