Died on the table. I can sometimes get it to boot, but the hard drive is now dead. For about three hours I used this system, with Wyse terminal, M/PM OS. Then "click click click..." This unit was rebranded and sold as part of a business system by a company called Sentinel, and they called the system the "Dimension Five" ... [ read more ]

Teltronix 4015-1
Tektronix made some nice programable graphics terminals in the 1970's. I believe I have the correct controller card for this terminal in my DEC industrial/11, but I have to experiment with it. Click image for larger view.

The Commodore 264 Series - C116, C16 and Plus/4 Computers Video: The video has photos from this site of my C-116's motherboard, (~5:30).
Screen shot from my C-116 (upgraded RAM) running the Tutti Frutti game. Full color.
One other thing; the presenter's said he could not get his C-116 to display in color on his PAL monitor in the UK. The presenter must have had issues with his display or cables. The 116 video is identical to the other TED machines, maybe he had something wrong with his.... [ read more ]

Somewhere in there is an Amiga 2000. Click for larger view.
I was hoping to find everything I needed to make a complete stand-alone a2000 system but I did not quite have enough parts and cables on hand. So, I borrowed parts temporarily from other places to test the power supply, motherboard and the required minimum controllers to make this a SCSI "Amiga 2000HD" with 040 processor card (!) system. I put the main chassis, power supply A2000 main controller (whatever you call the controller near the power supply) and a SCSI HD controller as a set, on Ebay. More photos... [ read more ]

Lear Siegler ADM-3A terminal with GraFix add-on board.
You can't tell from the outside, but this is a Lear Siegler ADM-3A terminal with GraFix add-on board installed. It also has a numeric keypad adapter cable that appears to have been cut off. The terminal has the typical screen rot bubbles of an ADM 3. .Click image for larger view.
Note the cables connecting from the main board to the GraFix board installed underneath. Click image for larger view.

Dell Dimension XPS 466V
The 1993 Dell Dimension XPS 466V was one of the nicer 486 gaming machines built before the Pentium era. Click for larger view.
This computer needs a real time clock battery (CMOS). Currently one has to run Setup for each cold boot. This system has two Caviar model 2340 341 Mb hard drives. I installed a 1.2Mb 5 1/4" disk drive for utility purposes and I may add a CD ROM in the remaining open slot below the 1.44Mb 3.5 inch disk dive in the middle bay.

Bill Degnan Appliance Computers Talk at the Vintage Computer Festival East 12, 2017
I was the Sunday Keynote speaker, my talk was titled, 1977: The year of the appliance computer
Event Photos 1977: The year of the appliance computer (Download PDF) The photos I took do not do justice to the actual exhibits and how they looked in person. First off they were all an amazing amount of work, classy, and great teams. All three mega exhibits were "best" in show as far I am concerned. We were talking about what we'll do next year with teams, never too early to start planning. I'd like to propose we try a vintage networking cluster, "pass the packet" or somethi... [ read more ]

Build a bootable RSX11/M on RL02 disk

Scan of my cover of the Digital pdp11 RSX-11M Beginner's Guide manual.
RSX-11M Manuals http://wwcm.syn...0Manuals.html This thread describes how one might use simH on a $9.95 Next Thing Co CHIP to make an RL02 image of RSX11/M V 4.0 BL 32 (BASELINE). I got the how-to via web search and clues from CCTECH and simH user group members interested in the project. My case - For my PDP 11/40 I have no working EIS option card. (Otherwise I'd be using UNIX 6.) I already have RT11 running but I wanted to try RSX11. I was told that RSX11/M v.4.0 BL 3.2 is the newest OS version compatible with my system. Distribution media disk images for RSX11/M can be found in RL01 format but not RL02, so I had to first build one RL01 boot disk using 4 RL01s and then port to RL02. [ read more ]

Last Post: [ DDP-516 8K core ] 02/03/2017
Photo of a Honeywell u-COMP DDP-516 control console. The orange color scheme was used in the 1966~68 u-COMP models, see early advertisements. Many people know of the "kitchen computer", the 516 is the same thing, same instruction set as the DDP-316 (H316). If the 316 is the Kitchen Computer, the 516 is the "business" model. This console would sit on the operator's desk, or on top of the computer cabinet, which stood about 4 feet tall (need to check that). The operator would use the console buttons and switches as one would use a front panel. There is also a blue cover version of this consol... [ read more ]
