Hello everybody, a friend of mine asked me to drop a note to the list, if anybody is interested in a so-called Data-Recorder from Mohawk Data Sciences Corp (MDS) available for pick-up in the region of Dortmund, Germany. He needs the space and wants it to find a new good home. System condition is unkown but complete according to my knowledge. Model type should be MDS-6401. Information can be found on bitsavers: http://bitsavers.trailing-edge.com/pdf/mohawk/M-319-66_MDS-6401_Brochure.jpg Please contact me off-list and I will get you in touch with him for those interested. Kind regards, Pierre ? ------------------------------------------------------------------------------- Pierre's collection of classic computers : http://classic-computing.dyndns.org/

SCSI to Pertec Formatted controller, anybody want it?

by elson＠pico-systems.com

I have a SCSI to Pertec Formatted interface that came off the back of a Cipher 990 drive. The drive was a horrible piece of junk, and we chucked it, but I kept the SCSI adapter. I tried it last year on a CDC Keystone (92185) drive, and was surprised it seemed to work. I was just trying to get some tape mapping software running when it died. The adapter was powered from the reel motor supply of the drive, so it needs something like 60 V DC, and has a switching supply built into the board. Anyway, it now gets a power on self test error and won't go any further. I do have full schematics for the adapter. If anyone wants it, it is yours for the shipping. Jon

3rd Party 11/730 memory boards

by aperry＠snowmoose.com

I have third party memory cards in my 11/750. The installation guide indicates that they also work in an 11/730. They are from National Semiconductor, NS753. alan On 1/5/14, 8:28 AM, Ken Seefried wrote: > > > I've seen a couple of vague references to 3rd party memory cards for the > VAX 11/730, equivalent to the M8750, that used denser DRAM chips in order > to use less power.

Huge UNIVAC/Unisys system-80 /DCP/tape documentation lot (110 kg/242 lb) still available

by p.gebhardt＠ymail.com

Hello list, more than a year ago, I offered a large lot of documentation originating from an Unisys system-80 computer which is a descendant of UNIVAC computer systems. Some binders are from UNIVAC, newer docs are from Unisys. http://classic-computing.dyndns.org/unisys/p1130068.jpg http://classic-computing.dyndns.org/unisys/p1130069.jpg http://classic-computing.dyndns.org/unisys/p1130070.jpg The Houston Computer Museum was/is interested but financing the shipping seems problematic due to missing donations. Unfortunately, I need to clear out a room this year and the four large packages with these docs have been standing in my way for very long now. Therefore, I'd like to offer again this documents to anybody who is interested has long as he pays shipping or grabs them at my place. Location is Germany near Cologne. If you are intersted, I can send you a list (not entirely complete, though) of the documents. I'd love see them go in good hands. I don't have the machine and thus have no use for the 110 kilograms of paper. A subset of the docs can also be sent to whoever is intersted. Please contact me off-list. Kind regards, Pierre ?
