"James M. Knox" wrote in message ... "Tarver Engineering" wrote in : I wrote my senior project on a CDC-4800, I don't think you can beat that. A real "main frame" computer. Actually, that's way newer than most of the ones I worked on. Heck, it had RTL IC's and (if I recall correctly) those wierd back-to-back cards. Not a vacuum tube in sight. The part that was instructive about the CDC4800 mainframe was that it was built on a frame similar to a telephone frame. The original I/O device was a card reader, but there was tape for it by the 1970s. |

Tom Pappano, PP-ASEL-IA, Ohio Scientific C1P 32k 6502 Dual floppy/ASR33 Man! Mine is absolutely modern. C28P, 48K dynamic RAM and dual 8" Siemens drives. Cost me $4,000 without a monitor or keyboard. I used a model 28 Teletype for a printer. Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair?) www.rogerhalstead.com Return address modified due to dumb virus checkers |

Do you want to know what a lightning spike does to a Bendix G15 [vacuum tubes, serial, drum memory]? |

Sad part is that my airplane predates most of these computers. When new,
the computers cost much more than the airplane, but now I bet you couldn't fill my tanks for what you could get for most of 'em! Roy Smith wrote: "James M.

Now we're talking. FIrst computer I built was an Ohio Scientific 6800 board.
I had been saving my pennies for the 6502 board, but managed to get one of the very first 6800 boards. I lost that board 3 years ago in a flooded basement, but I still have the original manuals that came with it. Tom Pappano wrote: Roy Smith wrote: Dan Truesdell wrote: Someone once told me that the term "winchester" came from IBM, where their non-removable drive was the 3030. Any truth to that? That's certainly the story I always heard. Goes back to the IBM-1130 days. I played with an 1130 some, but they were pretty much gone by the time I came around. I remember the "Winchester" as being a single platter sealed drive that gave you 30 meg with 30 ms access time. The drives quickly evolved into faster/higher capacity/smaller size units with the name Winchester continuing to be associated with the "sealed" method of construction. First actual 30-30 I remember seeing was an option on a line of Ohio Scientific microcomputers. Tom Pappano, PP-ASEL-IA, Ohio Scientific C1P 32k 6502 Dual floppy/ASR33 -- --Ray Andraka, P.E.

Manuals are great. I still have my original PC (ATT/Oliveti), but also
have the manual for the "Trash 80" I first learned on (with a whopping 4K of memory. Gotta love that "CLOAD" command, too.) Ray Andraka wrote: Now we're talking.
