[cctalk] Re: IBM 360

Yes, 1964, amazing. I remember, I must have some vintage IBM training/instruction materials on the 360, 704 and FORTRAN programming systems. This came from a long time computer professor who took these courses in the early 1960s, Dr. William (Bill) M. Myers (University of Montana) It's a

[cctalk] Re: bubble memory stable?

Hi Steve, the Sharp PC-5000 bubble memory is very reliable. It`s working flawless on two machines I have. Bubble memory was used as well in some significant older machines, like the Texas instruments Silent Terminals (around 77 I guess). And last time I turned on the terminal, it worked

Datapoint 2200 on ebay

In my opinion, the Datapoint 2200 on ebay seems to be a 1100 Cassette Terminal. There are two theories - It is a true 1108, as the silver machine label indicates. This 1100 versions showed up in 1974 as described by the LCFGROUP and have been a variant to the 2200 with less memory , using

Programming in 1946 - ENIAC's Birthday

75 years ago, February 15, 1946 The ENIAC, presented to the public in 1946, is - depending on the definition - the first programmable digital computer in the world. Its first programmers were primarily women: so-called refrigerator ladies (seen here: Gloria Ruth Gordon and Ester Gerston) spent

Re: For those with 6809 experience

My assumption is, that the LDA address access is too late at the end of the instruction cycle, and the CPU already started the next instruction cycle internally. HALT will be acknowledged only during the instruction cycle following the LDA. It would be interesting to measure, when the LDA pulls

Canon BX-1 (1977) Manuals

Recently, I’ve started working on a Canon BX-1 machine dated 1977. It was CANON's first standalone business / home computer featuring I guess the Motorola MC6809 CPU, one line of gas plasma display a thermal printer and 125k floppy drive. See pictures here:
