UNIVAC 1219 USS Midway CV-41by kingjr5872 Total messages in this thread: 1  John says: "I have a photo of me repairing one of two 1219 while on-board the USS Midway CV-41. They were a redundant system (configured like a Master/Slave) to land aircraft on a carrier automatically without the pilots control. We used two, in case one computer went down the other would take over. Pretty cool and oh yes many hours/days without sleep repairing an intermittent on these beasts. " Click image for larger view.
John uploaded new docs to the UNIVAC 1219 document library (sort by date). He says:
"Attached are two documents that describe how the Univac 1219 computer is used in the carrier landing system. I am still searching for other information about">... [ read more ]

Soltoff IBM 5150 with AST HotShot/286by billdeg 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 ]

Core Memoryby billdeg Total messages in this thread: 2 Updated: [ Early 1024 Rectangular Sense Core ] 06/07/2017  Hand-threaded rectangular core memory enclosure after cleaning and straightening wirewrap pins.

The outside of the frame. Click image for larger view.
 This false-color closeup shows how the pins used to hold the wirewrap in place have been bent. Note actual memory magnets are inside">... [ read more ]

Computer Encounters (of the 011rd Kind)by billdeg 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 ]

Quote from ZOSO, CPMUG 21 Archivesby billdeg Total messages in this thread: 1 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]). YOU GUYS HAVE EXPOSED YOURSELVES TO CAT- ARACTS AND MYOPIA BY LOOKING AT YOUR VDM'ED TVS. LEAVE ME OUT OF IT !!! THE COMPANY WHO SUPPLIED">... [ read more ] |

Altos 5-5ADby billdeg Total messages in this thread: 9 Updated: [ More OASIS tips ] 05/10/2017 
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"
