I borrowed David's cable for the repairs, I haven't yet tried to obtain the Berg connector or search my rubble for one. Contact me offline and maybe we can cooperate on this.
to All: I'll get my photos of my 8/F and 8/E work on my site pretty soon. In another post I'll give a link to the MARCH event photos I have.
retrotechnology.comWell, that's excellent to hear! Mine seems to be counting the accumulator quite well. I've yet to input any other programs, but I'll get there.I went ahead and made a cable tonight. I'm getting a whole bunch of garbage via my terminal emulator, whether the computer is halted or running. I don't have an oscilloscope where I am currently, though I'll be able to use one next Tuesday, most likely.I'll see what I can do with another cable. I am looking for a yellow switch for my 8/E, so keep me in mind if you have any spares. :)Kyle

Magnetic tape drives are *physically* sequential-access, of course, but the
TU56 (for example) is logically a random-access, block-oriented device. (with
highly variable latency ;))
