I have a bunch of 1200 and 2400's lying around, if anyone's interested (I might take them up to VCF and try to sell them there....)

Foam pads for keytronics keyboards ? (& SOL-20 with Helios for sale)

by Watzman＠neo.rr.com

This will seem like a digression, but it's not. I have a SOL & Helios pair on E-Bay right now (if you are interested, hurry, it ends tomorrow): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5112120888 If you read the auction, I discuss the keyboard issue at length and in the set of 12 photos for the auction I even took a photo of a keyboard being rebuilt. I'm surprised that no one asked me where I got the foam pads. Anyway, they came from: Mike Stephens Mil-Key Corp. m-corp(a)qwest.net You can buy a new PC (cordless) keyboard for what it will cost you to rework a SOL keyboard (or any other Keytronic keyboard using these pads), but as far as I know it's the only source. HE SAYS THAT WHEN THE CURRENT SUPPLY IS GONE, THERE WILL BE NO MORE, ****EVER****. AND HE SAYS THAT IT'S ALMOST GONE. You can see a photo of the pads in the SOL auction above. They are different from (and, I'm hoping, superior to) both the original pads and the later ones used in the Sun keyboards.

Teac floppy replacement

by RCini＠congressfinancial.com

Thanks for the info. I guess for this test I have to find a replacement high-denisty drive. The drives in the unit are, apparently, high-density drives but the disks are 360k disks made with another working system. -----Original Message----- From: Don Maslin [mailto:donm@cts.com] Sent: Wednesday, August 04, 2004 12:41 AM To: rcini(a)optonline.net; General Discussion: On-Topic and Off-Topic Posts Subject: Re: Teac floppy replacement On Tue, 3 Aug 2004, Richard A.

Rich, the 55F is a 96tpi drive while the 55BV is 48tpi. That difference is likely the cause of your problem. - don > > Rich Cini > Collector of classic computers > Build Master for the Altair32 Emulation Project > Web site: http://highgate.comm.sfu.ca/~rcini/classiccmp/ > /************************************************************/ > > >

GRiD Compass II 1137

by JMeyer101＠aol.com

I picked up the Grid with no documentation. The device boots up and lets me choose an OS (either MS-DOS 2.11 with BIOS Version C or Version 134.1.4 GRiD-OS / Version 31.0.0 of Common Code). If I boot into MS-DOS, I get an A: prompt. If I do a "dir" command, it brings up 3 files but that's it. If I boot into the GRiD-OS, I can get to some menus, but then it needs a password to continue. Does anyone know a hack to bypass the password? Or does anyone have access to the GRiD-OS software so I can reinstall? I would like to get this thing working but it is very difficult to find any information. Any ideas? Thanks, Jeff

rarest computers

by dwight.elvey＠amd.com

Hi OK, I do have one that is going to be an unusual one that is significant in its insignificance. It is a SDK development machine for Intel's 2920 ( not to be confused with AMD's 2920 of the 2900 family of parts ). This was Intel's only attempt at the DSP market. It is only unique in that it is rare enough that few even know it existed. It was a time when Intel chose it's direction to be a mostly X86 processor company and began to leave the side markets alone ( for good or bad ). There may be others out there but I've not seen any.
