Kyle, while you are at it, maybe you can do me a favor also, and make a cable for *me*. David Gesswein, with my assistance, got my 8/F running at the recent MARCh Fix-it last weekend. I too need a RS-232 cable, or at least the connector at the serial end. I have the M8655 board, in fact I now have two of them:
which uses apparently the same cabling as your M8650.
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.

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 ;))
