This sounds more like ESDI to me. If memory serves
that was a two
cable system.
RLL and MFM were too, now that I think about it, although not 50 pin cables.
I'm betting ESDI.
The only true ESDI system, not counting the IBM DBA interface
used in some of the PS/2 series, that I have here is in my MicroVAX
II and it had daul Maxtor XT-8380E's installed. Full height 5-1/4"
drives of 380meg each. I pulled one of them out to replace it with
the TK50. Anyway, the cables for the drives are the same width as
MFM/RLL drives: 34 and 20 pins. This is verified by comparing it
directly to a Tandon TM-502. Wasn't ESDI an outgrowth of the ST-506
drives/interface?
