Reading data from a CDC Hawk Drive

by kevin＠xpuppy.freeserve.co.uk

As part of an emulator project I need to read data from many CDC Hawk packs. I have a drive and I believe it is an SMD interface. The drive also seems to be known as a DD1600. Does anyone have any details on this drive? Two possible options occured to me:- 1. Obtain (?) an SMD controller card for a PC and try to access the drive using this - and an appropriate amount of C. 2. Use a QBUS SMD controller in my PDP11 and get at the data that way. Any thoughts gratefully received. (BTW The machine I am emulating is an old British minicomputer called the Molecular.) Kevin Murrell ------------- www.ps8computing.co.uk

Sources for punched cards

by hansp＠aconit.org

OK, I remember readding here some time ago that there were still sources of new punched cards in the states. My searches have come up empty. Can anyone point me at a company that still supplies punched cards. I would prefer one in europe but that would probably be asking too much Regards, -- HBP

Osborne 1 Keyboard (was RE: Reading non-PC format floppies (+ OT questions :-))

by Robert_Feldman＠jdedwards.com

I have an Osborne 1 Technical manual which has info on the keyboard and some schematics, as well as a printout of the BIOS source. I'm out of town now, so I'll try to get it (at least keyboard info, as the BIOS source is many pages) to you on Monday. Bob Feldman -----Original Message----- From: wrm(a)ccii.co.za To: classiccmp(a)classiccmp.org Sent: 10/26/01 2:36 AM Subject: Re: Reading non-PC format floppies (+ OT questions :-) <snip> (1) Osborne 1. - Keyboard is shorted internally. Screen reads "insert disk and press Enter" or whatever, then refreshes / redraws all the time. This stops when I unplug the keyboard. I think I know which two pins connect to the Enter key, when I short those two pins same thing happens. I'm suspecting the 8877 FDC chip. Does anyone have: -- Memory (I/O) map -- Schematic (ja sure :-) -- BIOS disassembly -- tips on fixing the keyboard? <Snip> Wouter www.retro.co.za

Hmm, if that drive number is 5246 then this one must be for the Displaywriter. Paxton

IBM 8 Inch Drive

by univac2＠earthlink.net

A dual IBM 8" diskette drive is for sale on eBay: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1287758038 It looks like the Display Writer drives to me. Will it work with a System/36 5362? The connector on the drive looks like it matches the connector on my 5362.

I don't know what the extra plug is for other than you need both to plug into the system. Paxton Astoria, OR
