WANTED: DEC TU56 DECtape drive

by jnc＠mercury.lcs.mit.edu

> From: Thomas Moss > Probably a long-shot, but I'm looking for a DECtape drive for my > PDP-8/e. Long shot indeed! DECtape drives are one of the rarest DEC peripheral, and un-surprisingly, one of the most valuable. (A TU56 sold on eBait for $7K back in 2015.) Would a TU55 do, or does it have to be a TU56? (The interface is basically compatible, I think, but I have yet to dig into the details, so I can't say for certain. But I think I recall seeing systems with one or the other, and AFAIK the controllers aren't drive-type specific - the cabling might be, though.) Noel

Looking for a Motorola Universal Data Systems 212A/D manual

by mbbrutman＠brutman.com

I ran across this modem (circa 1982) and saved it, but I have no idea on how to control it. Bitsavers doesn't seem to have a manual for it. It's a big, blue plastic box and it looks wonderful. There is an array of 8 lights and 6 buttons; the HS button enables 1200 bps operation, otherwise it is 300 bps. It echoes characters and responds correctly to DataTerminalReady not being asserted, so I think that if I can find the command set it might be functional. It's a little more primitive than my original Hayes 1200 that I first got in 1984. (I'm not expecting a standard command set.) A picture of it can be found here: https://photos.app.goo.gl/zWBPimcpZNUch6G28 Thanks, Mike

SMD disk specifications

by shadoooo＠gmail.com

Hello, I also was searching about a clear SMD specification years ago, I found something in disk documentation from CDC, but doubts remain, because some disks call the interface SMD, some other CMD, never understood the difference... Andrea

SMD disk specifications

by shadoooo＠gmail.com

Hello, well maybe my memory has blank spots. I have two CDC Lark Disk modules I would like to revive, they are in good shape, but only one has a cartridge included, and they are not identical. Not sure if the other one could be employed without cartridge. I never found a manual with exact model correspondence, I found years ago a manual for very similar drives. IIRC there was a sort of adapter board between SMD and (xxx blank spot) interface. There was a description of the interface, it was really similar to SMD, but wasn't SMD... Maybe I should check again the Lark model number. Andrea

SMD disk specifications

by ggs＠shiresoft.com

Hi, I?ve been trying to find *detailed* specifications (mainly detailed signal timings) for the SMD disk interface but all I?ve found so far are the interface specifications for individual disks (CDC, Fujitsu, etc). I?ve looked in the usual places (bitsavers mostly) and haven?t found the spec itself. If anyone has any pointers, I?d appreciate it. Thanks. TTFN - Guy

WANTED: DEC TU56 DECtape drive

by mosst＠SDF.ORG

Hi All, Probably a long-shot, but I'm looking for a DECtape drive for my PDP-8/e. Either to buy or to trade with something. (PDP-8/11 parts, 11/34, Intel MDS, ASR-33?) I'm in South-West England but also have an address near LA. Can travel to pick-up. Regards, -Tom mosst at sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
