Soltoff IBM 5150 with AST HotShot/286by billdeg - 06/11/2017 Total messages in this thread: 1 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 ]

Computer Encounters (of the 011rd Kind)by billdeg - 06/02/2017 Total messages in this thread: 1 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 ]

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.
