Hmm, I'd be interested in any info. anyone has on these things. I had the remains of one a while back - someone had grabbed the drive out of it before I got to it but all the controller logic was still there. I seem to remember that it was a useful source of parts - nice solid case and compact toroidal power supply... it's a shame I didn't have the actual drive to go with it and to mess around with. I don't know what would have worked with it, we mainly had Cambridge Ring network gear back then, a few VAX machines, and not a lot else... cheers Jules >

A quick boot > doesn't require a ROM OS, though. Flash upgradable ? Huh ? Did I miss something ? Afaik my MP2K still has ROMS not Flash for the OS. Same for the eMate.

MicroVAX III Memory

by kyrrin＠jps.net

Fellow DEC'ers, I've come across a KA650 (MV-III) CPU board. As near as I can tell from comparing the pinouts of its memory connector vs. the MV-II memory boards I have, it uses specific memory boards of its own. 1). Anyone got any MV-III memory for sale/trade? 2). Failing that, is it at all possible, however messy, to modify MV-II memory to work? Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

Info wanted: Digital RZ23 SCSI Drive

I used these settings in my format.dat file for a Sparcstation: ncyl = 772 ; acyl = 2 ; pcyl = 774 ; nhead = 8 ; nsect = 33 ; rpm =3600 The SCSI ID is set by three jumpers next to one of the large custom chips on the control board. The jumper nearest the edge of the board is ID0, the one nearest the chip is ID2. Jumper fitted = 1, unfitted = 0. I don't have any jumpers on other pins. There are some pins on the front, in a 14-pin connector. I can't remember what they all do except that the pair nearest the centre of the drive are for the LED. This drive doesn't spin up until given a Start Motor command, and the DEC firmware is different to the standard Connor firmware so there is no jumper setting to control this. > > I think the original manufacturer was Conner.

The diagrams there, for the "obvious" Connor equivalent, are mostly correct for the RZ23, IIRC. That's where I originally got most of the information, a couple of years ago. -- Pete Peter Turnbull Dept. of Computer Science University of York

more random bits need new home

by pcoad＠ncal.verio.com

Due to the volume reduction act of 1998 I need to find homes for a few things which I can't use but others might find useful/interesting: 1.) Box of 8 inch floppies unknown condition: a.) digital software (BA-M386A-BA) WPS-8/DECMATE V2 BIN MATH RX2 b.) digital software (BA-M471A-BA) WPS-8/DECMATE V2 BIN SORT RX2 c.) digital software (BA-M470A-BA) WPS-8/DECMATE V2 BIN COMM RX2 d.) digital software (BA-M469A-BA) WPS-8/DECMATE V2 BIN LIST RX2 e.) digital software (BA-M387A-BA) WPS-8/DECMATE V2 BIN BASE RX2 f.) digital software (BA-S968B-MA) ALVTAB0 DECMATE SYSTEM TEST REPLACES: AS-S463A-MA g.) hand labeled intel "SA/FT/FMS Priam Interface, SMD Interface for updated byte/serial PCB's" h.) hand labeled Dysan "Backup of Priam test programs" The box is one of those that can be attached to others of the same type. Manual and labels for box included. Whoo-hoo. 2.) IIT 2C87 "Advanced Math CoProcessor". That's right, this is basicly a 80287 math coprocessor. This particular model is suitable for 10 MHz or slower 286 machines. The box is still shrink-wrapped if that turns you on. Includes free ComputerLand sticker on the side of the box. The box says that this "features a power-down sleep mode. In active mode it consumes 25% less power than other coprocessors." Speed up those 1-2-3 recalculations and floating point intensive tasks! 3.) MS-DOS 4.01 (ACBEL Technologies version). Includes box, 6 5.25" disks, 2 manuals (Microsoft MS-DOS User's Guide $ User's Reference and Microsoft MS-DOS Shell User's Guide). The box and manuals are black and white, but the disks are green. Go figure. 4.) Farallon PhoneNET nubus card. This one has AUI and 10BaseT connectors. It may work, it may not. I have no way to test it. 5.) Apple Ethernet nubus card, I believe. Has AUI connector without the funky slide locking device and a BNC connector. Connect your Mac II to your home network. Untested but big. Make me an offer. Trades of random old/cool/strange/small Sun stuff preferred, cash accepted. I don't expect much for these. Everything is As-is. The first person to make a deal for more than one item will get a free copy of "Inside the Amiga" by John Thomas Berry.
