Soltoff IBM 5150 with AST HotShot/286

:"IBM
AST HotShot/286 upgrade board. To install one would remove the 8088 chip from the motherboard and replace with the small controller card with embedded 8088 installed. From this card a cable runs to the HotShot/286 board, with i286 processor. The negative to this arrangement is that the 286 processor is on the ISA bus. Click image to see files.in this set
Many years ago LDOS creator Roy Soltoff gave me an IBM PC model 5150-B. Both hard drives were marginal and eventually went completely dead. Roy's computer contained an AST HotShot/286 card so I thought it was worth backing up his files and putting in a new hard drive. The drives were too far gone, but I was able to use the Seagate ST11R drive contro">... [ read more ]

Core Memory rectangular enclosure
Hand-threaded rectangular core memory enclosure after cleaning and straightening wirewrap pins. Imagine you're looking at the edges of a set of cores stacked on top of each other within this enclosure. The backplane of wires you see is the "loop around" side of each core plane wire. The outside of the frame. Click image for larger view.

Computer Encounters (of the 011rd Kind)

Interesting trade show promo pin. Presumably "Computer Encounters" is a reference to the 1977 movie Close Encounters of a Third Kind. I could imagine a sales rep traveling from San Antonio to the 1977-78 Trenton Computer Festival and/or PC '77 (Atlantic City) or '78 (Phila) convention with a small box of these pins. The chip itself appears to have been cut, the die is off center. Click for larger view.
The rear of the hand-cut pin, just two pieces of cardboard and a styrofoam pad in the center to hold the chip. I still need to check to see if">... [ read more ]

From CPMUG 21: BITCH, BITCH, BITCH !!! SOME PEOPLE ARE JUST INCAPABLE OF BEING CONTENT. NO SOONER THAN I HAD FINISHED MY REPLY TO ALL OF THE TTY PEOPLE (VOLUME 13.21), TONY INFORMED ME THAT SOME VDM OWNERS HAD TROUBLE READING MY 80 CHARACTER LINES ON THEIR QUAINT I/O DEVICES. I WILL NOT ACCOMODATE YOU, AND HERE'S WHY: I PAID GOOD BUCKS FOR THE TOOLS I USE, AND I CHOOSE TO USE THEM. FRANKLY, I CAN'T FATHOM WHY ANYONE WOULD ADMIT TO OWNING ONE OF THOSE THINGS AT ALL. I'VE SEEN WHAT YOU GUYS ARE UP TO: THOSE HORRID, NARROW LITTLE PROGRAMS WRITTEN IN PROCESSOR TECHNOLOGY'S 5K BASIC (YOU KNOW THE ONES WITH A LINE FOR EVERY SINGLE LITTLE THING - 15 DECWRITER PAGES JUST TO PRINT YOUR VERSION OF WUMPUS [ABOUT WHICH I SHALL BE HEARD FROM LATER]).

DEC Rainbow PC100-B2 with VR241

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..."

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: https://www.yo...ch?v=s7Jf402LDa0 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 ]

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.
