Wanted: TU58 DECtape II Drive

Posted on Jan 17th, 2014

  • Vintage Tektronix curve tracer(s), particularly models 570, 576, or 577
  • Tektronix 600 series direct-view storage tube (DVST) monitor, especially the 611
  • Syquest SQ200 cartridges for the 10MB SQ312RD drive. Not to be confused with the SQ200 drive, which is a horse of a different color.
  • Parts and accessories for my Czechoslovakian M-125-3MR2 “Fialka” (ФИАЛКА) cipher machine, as described here at the Crypto Museum site:
    • All power cables for the standard power supply: I do not have any original cables, and I currently use a kludge of banana test leads.
    • Cyrillic print head: My machine just came with the Czechoslovakian print head. I don’t have a Cyrillic print head, or any of the dust covers or clips for storing extra heads in the machine’s lid.
    • Wheel opening tool for the later style adjustable wheels
    • Test reflector, and the retainer clip for storing it in the machine’s cover
    • Metal guide rod that goes at the left side of the top cover (mine is missing)
    • Tool kit
  • Items for my DEC VAXstation 3100 Model 38:
    • Bezel for TZ30 tape drive option, 74-37501-01
    • Color monitor, VR160 (preferred) or VR290 (big!)
    • Color video cable to match VR160 or VR290
    • DEC-branded BNC tees and terminators with plastic overmold
    • External SCSI terminator for the 68 pin plug
    • Caddy-loading SCSI CD-ROM drive with either DEC external enclosure or proper bezel to install it in a VAXstation 3100
    • DEC LA75 printer
  • Teletype BRPE punch, especially one for 1 inch 6/7/8-level tape
  • Teletype DRPE punch
  • A VAX-11/725 system: I have an 11/730 already, and I’m really curious about the 11/725’s RC25 drive.
  • PDP-11 and/or microVAX systems in BA23 deskside cases, particularly with RX50 or TK50 drives. I like the looks of these.
  • PDP-11 or microVAX system in BA123 case. I have a hypothesis that one of these would make a good nightstand when it’s not turned on.
  • DEC PDP-8/M OMNIBUS peripherals, cards, and supplies:
    • High-speed paper tape punch/reader
    • DECtape subsystem, any variant
    • DECtape media
  • DEC PDP-11 series UNIBUS peripherals, cards, and supplies:
    • High-speed paper tape punch/reader for fanfold tapes
    • Any interesting original paper tapes which I don’t already have
    • Blank fanfold 1″ paper tape
    • RK05 drive subsystem: I have a 12-sector RK05 pack, but no drive to go with it.
    • 12-sector RK05 packs
    • RK05 alignment pack
  • DEC PDP-11 series QBUS peripherals and cards:
    • M8018 KUV11 Writable Control Store card
  • Aluminized printer paper for my Racal MA-4233 printer. Referred to as “electrosensitive paper” or “metal paper”, I believe. It uses 60mm wide rolls of approximately 42µm thick paper on a plastic core of around 12mm diameter (though the core isn’t critical in this printer), with a very thin aluminum coating over a dark paper substrate. While exact drop-in rolls would be great, I’d consider any wider size which I might be able to cut down, as well as large rolls or sheets of this kind of paper for use in my AN/TXC-1 facsimile machine.
