Digital PDP 11/05 S in BA11-Kby billdeg Total messages in this thread: 13 Updated: [ Replaced h745 -15V ] 08/21/2018  Started working on piecing together a PDP 11/05 S in a BA11-K Mounting Box. Pictured here are the fans that cool the H765 power supply's transformer. Note there are no DC voltage bricks installed. I removed the metal fan covers (they were rubbing the fan blades when you spin the fan manually). Click for larger view.

Rockwell R6500 (AIM 65)by billdeg Total messages in this thread: 8 Updated: [ Cassette Signal Issue ] 07/21/2018  The Rockwell model R6500 was better known as the AIM 65. The AIM 65 is a 6502-based single board computer from 1976, although the model remained popular through the early 1980's until it was eventually replaced by the AIM 65/40.
AIM stands for "Advanced Interactive Microcomputer" and the 65 most likely is a reference to the 6502 processor and related chips. Right?
I have two AIM 65 systems, one was fresh out of the box and never used. I am doing my experimenting with the used unit. I also have a 8-slot card cage containing a general purpose module, Serial card, disk controller, and video controller. The system boots to the system monitor and then I can jump to BASIC. I have run some assembly programs and some BASIC programs.

SGI Octane OS install 6.5.12by billdeg Total messages in this thread: 1  Pictured is the SGI desktop with a telnet connection to the Level 29 BBS via the IRIX console program. Telnet BBS-ing is a good way start testing a network connection. Click image to see more photos
SGI UNIX is called IRIX. I first installed version 6.5 but then learned the hard way that an "Overlay" would be required if I wanted to use an external DNS beyond local IP networking. I fortunately had a copy of IRIX 6.5.12 Overlay (OS patches / updates) which did the trick. I have been told it's even better to find a newer version, 6.5.2x. IRIX:

Apple Lisa 210 A6S0200by billdeg Total messages in this thread: 2 Updated: [ Keyboard Restoration ] 06/12/2018 In preparation for class demonstration of the Apple Lisa 2/10 I took some new photographs. 
Minor repairs were needed. I had to take apart the keyboard because the space bar had dislodged from the little clips that hold it in place. I also replaced the MAC mouse with an original Lisa mouse. Note the new pictures have the original mouse.">... [ read more ]

C128 Display Cables and the 1084 Monitorby billdeg Total messages in this thread: 1  with the Commodore 1084 display one can switch between all signal modes generated by the Commodore 128/128D computer.

 The CVBS / LCA button on the rear of the 1084 is in the LCA (out) position. This is required to display color while in 40-column CVBS signal mode (C64 or C128). If in the display will be grey. The position of this switch is ignored if you're using the RGB cable (80 column mode). Click image for larger view.

1993 HP NetServer 4d/66 LMby billdeg Total messages in this thread: 3 Updated: [ Power Supply Bad ] 07/12/2018  The HP NetServer 4d/66 LM with Pentium 66 upgrade installed was among the initial class of Pentium 60/66 machines sold in the USA. As far as I can tell, the name plate is the only thing differentiating this unit from a 4/66 LM that shipped with the Pentium installed by the factory. I have the 486 EISA card that was removed from this computer after it received a field upgrade. Click for larger view.

MITS 8800b Turnmon 9600 baudby billdeg Total messages in this thread: 7 Updated: [ VG Monitor, TURNMON, Front Panel Altair ] 02/07/2018  A view of the on/off key on the Pertec / MITS 8800b Turnkey model. The system required some minor repairs, a short was detected in the turnmon board preventing I/O from the Turnmon board. I repaired some burned out traces and set the baud rate to 9600.
 View of a repaired turnkey "turnmon" board. Note S0, S1, and S2 are jumpered to produce 9600 baud. S0 required minor repair, some of the original trace metal was lost. The staining is only cosmetic. Click image for larger vie">... [ read more ]
