Re: DEC VT 420 comm cable?
I've got 1000 feet of DEC OfficeConnect flat cable, a bunch of MMJ ends, and the crimp dies for them, if anyone finds themselves in need of cable.

Re: Assessing Plastibands for QIC Tension Band Replacement
I'd seen your posts earlier, as luck would have it I've also been going through some QIC tapes lately. I've been working with a US-based custom rubber products manufacturer on finding replacement drive bands. Nothing to report back yet, first round of samples felt like the right material but were the wrong size (my goof, I think).

Re: DECServer 200/DL board?
I wonder if that's a DECserver-100 board. I remember seeing a box (I thought it was a prototype but I may be confused) with a fairly small PCB inside a much larger rackmount-sized enclosure, with 8 separate wire bundles going from connectors on the board to the MMJ jacks on the front panel. The history supposedly was that the original design used a box the size of the board, with those connectors either exposed on the front or brought out to standard front panel connectors. Ken Olsen decreed that the connectors weren't acceptable and introduced MMJ, requiring the box to be redone but the PCB was kept. Or so I was told anyway. paul > On Jun 18, 2018, at 12:50 PM, Al Kossow via cctalk > wrote: > > Is this a 200/DL (RS423 data lines only) board? > > https://www.ebay.com/itm/352381870034 > > A normal 200 would have two large IDC connectors on the pcb for serial I/O > >
