Thanks to everyone who responded. (And for the pointer to the BA11-N prints;
I had that print set, just hadn't look all the way through it! Although I still
hope a copy of the Tech Manual shows up some day.)
From: Pete Turnbull
For each BDAL line I used a suitable length of
wire-wrap wire to run
the length of the bus plus an allowance to wind once round each pin. I
stripped somewhat over an inch of of insulation from the end, then used
the stripper to separate the remaining insulation everywhere it would
solder to a pin. Soldered one end, wind once round every succeeding
pin, and soldered each.
Thanks for that tip - I had been planning on using separate lengths, but one
piece made a lot more sense. (Although I used wire from a 25-pair telephone
cable - I like working with that, it takes solder very easily, which not all
wire wrap wire will.)
