I bought the card, which I could always use in my 11/44 project, too. Now I'm trying to learn about the drives. I understand the TUK50 board has a 26ish-pin header for the drive cable. I see an ugly-looking TK50D external drive on eBay, but it appears to have a 50-pin D connector. There are also some TK50Z SCSI (?) external drives listed, which I presume are not applicable. Maybe I'd need to get an internal drive and cobble together a power source. That's because I just bought the only M7547 listed! ;) -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/ ----- Congrats, I cannot remember sales below $50 for a TUK-50 module. This is from (old) memory cells, so I could be wrong ... AFAIK, the external box-based drives (whether the box contained a TK50, TK70, or RD5x) always used a 50-pin 3-row D shell connector. When the TK50 is inside the cabinet it is a smaller cable - 26 pin could be it. As said, I can check next Saturday, but other readers sure can answer this one too. With the TK50 in the cabinet you need a PSU, the external TK50D would be a good source. The PSU is nothing special though ... TK50Z drives are OK with a DECstation or VAXstation (?) or XXXserver, their interface is indeed SCSI. Not 100% sure, I'd need to RTFM a bit. - Henk, PA8PDP
