Trade List

 

Items Wanted

Here is an incomplete list of things I am looking for, in no particular order. I’m located near Riverside, California, USA.

  • Vintage Tektronix curve tracer(s), particularly models 570, 576, or 577
  • HP/Agilent 16702B logic analyzer with some good timing/state analysis plugins
  • Tektronix 600 series direct-view storage tube (DVST) monitor, especially the 611
  • 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 VT220 terminal
  • 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.
  • Inspired by TM 11-5895-1412-12&P for Basic Generation Unit AN/GYK-33, I would like to put together an HP Portable Plus computer system:
    • HP Portable Plus computer, preferably with 512k RAM; AKA Model 110 Plus; AKA CP-1836/G NSN 5895-01-254-6699
    • HP Model 9114B disk drive (HP-IL interface); AKA RD-592/G NSN 5895-01-254-6700
    • HP Model 2225B Thinkjet Printer (HP-IL interface); AKA NSN 7025-01-199-8707
    • Related accessories such as HP-IL cables and other HP-IL peripherals
  • HP Series 80 accessories for my HP-85B:
    • 82938A HP-IL interface module
    • 82939A RS-232 interface module
    • 82940A GPIO interface module
    • Tape cartridges: Almost all of them are bad by now, but a small number of them might be repairable.
  • HP-IL (the silly serial loop bus) peripherals and cables. I have an HP-IL interface for my HP41c calculator, but alas, I have nothing to plug it into.
  • Items for my Collins 618T-2 HF SSB aircraft transceiver project:
    • Shockmount for PP-2352/UR inverter (part of AN/TRC-75)

    • Original manual TM 11-677 (I have a PDF already)
  • A vintage mechanical Hellschreiber teleprinter
  • AN/PRC-66 items:
    • Antenna
    • Guard receiver module (I think I’ve heard that these are somewhere between hen’s teeth and nonexistent?)
    • Manual(s)

  • Pinball machine from the 1970s through 1980s which is new enough to have electronic control, but old enough to not have a dot matrix marquee display
  • Bally slot machine, either electromechanical or microprocessor-controlled with mechanical wheels, of the sorts commonly installed in Las Vegas during the 1970s and 1980s
  • Surface grinder
  • Bridgeport type vertical milling machine, either an actual Bridgeport made one or another brand of comparable quality
  • Height gauge and related equipment for metrology and layout on surface plates
  • 120/208VAC 400Hz 3 phase engine-driven generator set, 120/240VAC 60Hz single phase powered motor generator, inverter, or generator head, capable of providing at least 1.5kW of 120/208VAC 400Hz 3 phase power
