I've seen it twice now that I have a machine that has a flaky disk and I open it up and see a terminator on both drives. Removing one brings back normal operation. One of the machines was a KayPro and the other was my Olivetti M20. I suspect that these were that way from the beginning since both normally ship as dual drive machines.

Origin of "half-inched" - OT

Supply of DEC 11/23 11/73 front panel switches

by jwest＠imail.kwcorp.com

Found at a local surplus dealer... a whole container of those square white pushbutton switches that I am pretty certain are the ones used on the "front panel" of the 11/23 or 11/73 systems. They have the following markings.... ITW 39-23 301 R 39-23100 89 16 I think they had them marked at 0.59 each, if these are the right ones (got it at work actually, haven't had a chance to go home and check they are the right ones) and anyone wants any, let me know.

Need help with DSSI/SCSI and an ext CD-ROM

by Fred.van.Kempen＠microwalt.nl

Curt, > On the 4000-200 on the far left side of the QBus slots is > a slot with 2 connectors, one appears to be a standard > SCSI-1 connector and the other is an inverse SCSI-2 connector > (labels Bus 0) with a terminator on it that lights up on power > up. The first one indeed is a SCSI connector. The second one is the DSSI bus connector, connected to bus #0. It should be terminated (with the lighted term) unless you have an external storage cab, which then in turn has the term. The SCSI connector, however, is NOT usable for what you're doing. The BA440 box (which is what your cab sounds like) has provisions for changing its internal (DSSI) bus into a SCSI bus, for example to be used with the KFQSA controller. That way, you can use SCSI devices with the VAX by mounting them in the old DSSI rails. The VAX does _NOT_ have a SCSI controller by default; unless you have something like a KFQSA, Dilog or Emulex SCSI-to-Qbus controller, you can NOT use the RRD43. Sorry to be the bringer of Bad Newz (tm).. Cheers, Fred

IBM 5150 brings $910 on EBAY

by xds_sigma7＠hotmail.com

Well, I can't speak for anyone else, but if you can find the ones with the cassette port easily, then I hate you. I've only ever found one, and the case was in poor shape.. I pitched the case, but the mobo is sitting next to me... HAH! Mine is more R@RE! LQQK! 37ï†3! than the Ebay one, cause I have an 8087 marked "IBM".. Which, I must say, is something I haven't ever seen before... And no, I'm not claiming that is indeed rare, beats me, I just thought it was nifty... If I had kept all the PC stuff I had, I could likely have made more than that auction, since I had the complete technical references and troubleshooting diskettes and pretty much every genuine IBM option you could want.. I have a CMI IBM HDD, and an ST-506 IBM HDD, numerous IBM floppies, never have found the p-System, however.. But hell, I had genuine IBM loopback plugs.. lol..

DECstation-3000/400 Questions

by bob＠jfcl.com

I picked up a DECstation-3000/400 (aka PE40A) at the flea market recently. It powers up OK (the power light comes on, the fans run, and checking the voltages on the power supply connector gives reasonable results) and all eight LEDs on the back panel turn on, but after that nothing. There's no video that I can find from the PMAGD card; there's no RS232 output on the console/printer port; changing S3 has no effect on either of these results, and the eight LEDs never change (always a bad sign!). I tried removing all the SCSI devices and all the Turbo channel cards (including the PMAG) just in case one of them was hanging it up, but it made no difference. Now there's nothing in there except the power supply, the mother board, and eight SIMMs on four riser cards. Same results. I have lots of VAXes, but this is my first Alpha machine and there might be something I don't know. Am I doing something stupid, or is it just dead? BTW, I only paid $1 for it, so I won't feel bad no matter what :-) Thanks, Bob Armstrong

cp/m favorite?

by IVIE＠cc.usu.edu

Mark Tapley said: > As usual, my favorite is the DEC Rainbow. Z-80 for CP/M, 8088 for CP/M > 86-80, both available via anonymous update from ftp.update.uu.se, and you > can even run (early) MS-DOS, I gave up on teh Rainbow because it was not good enough as either a CP/M or MS-DOS box. The IOBYTE didn't work from the Z80, for instance. I kept running across MS-DOS software that needed PC compatibility. The COMMAND LINE version of Turbo C V1.2 made ROM BIOS calls. I had to trade with a friend who had purchased 1.0. My favorite was the DECmate II with the APU card. The IOBYTE worked, it's the only machine I've used with an intelligent hard disk partitioning scheme [1], and the terminal emulation was much faster than either the Rainbow or the PRO 350. [1] There was a simple filesystem managed by the 8051 that ran the hard disk. Creating a partition involved telling the 8051 to create the file. Mounting a partition involved telling the 8051 to open a file and associated it with a given drive number. -- Roger Ivie ivie(a)cc.usu.edu

vax 7610 needs home, cambridge massachusetts

by akb+lists.cctech＠imap1.mirror.to

Hi-- A friend has just told me that there is a VAX 7000-610 system in cambridge mass looking for a home. The system is to be disposed of in the next week or so. It's currently at a ground level loading dock. It's a 3 cabinet system, storage peripherals include a pair of ra92's, a tz857 stacker, a 9-track, and (I believe) 3 ba-350 shelves. I have warehouse space in the area and could be convinced to temporarily hold the system for pickup. I'll read both this address and the list for any interest... I have also written to the Rhode Island Retro-Computing Society, other places to post to welcomed... (any appropriate usenet groups?) --akb

sharp

by konieczny＠intranet.ca

Hi Mike, I noticed on a Q&A board, you mentioned you have a sharp PC-1421 handheld computer. I'm interested in possibly using it to help control the stepping motors in a small robot, but I need the pinout for the 11-pin connector, and the memory location that controls them,.. Do you know where I can find that info? Thanks, Jeff
