If I can make it work without being too big a pain, I'll probably sell some as well. There seems to be a strong (but small) demand >from folks who love their IIFXs. At this point I'm not even certain that I can make the circuit boards reliably and affordably. On the other hand, until a couple of weeks ago I couldn't even find .047" copper clad board. Finding a source of that is what got me going. Jeff Walther

Country conversion for HP 791x drives

by peterbrown10＠hotmail.com

Hi All, I'm trying to convert a couple of USA spec. HP 7914 hard drives to UK spec. This involves not only changing the input tappings from 110 Volts to 240 volts but also changing the main drive pulley and drive belt to compensate for 60 Hz / 50 Hz mains frequency difference. Machining up a revised (larger) pulley isn't a problem but finding the drive belt is proving difficult. Is there anyone on list that has the necessary parts (perhaps a scrapped drive in the UK)? I think that the parts are common for the 7911, 7912 and 7914 drives - the HP part number for the belt and pulley are - 07912-20013 (pulley) and 07912-40018 (drive belt). Does anyone have experience of these drives? The pair that I have are quite grubby on the outside, have probably been knocked about a bit in transit but have had the spindles locked and the head leaver in the 'locked' position - is it likely that they will still work?

VMS Question...

You haven't worked on the 86x0 systems, I can hear... The 6000 series are a joke in comparision. The 86x0 systems are designed to continue to work even when chips actually don't work. Those faults are logged, alternate signal paths are activated, and the board should be scheduled for replacement at the next normal PM. So yes, there are double sets of registers, paths, and whatnots, so that most faults actually don't stop the machine from running.

Mass Memory Unit from Space Shuttle

by rigdonj＠cfl.rr.com

I found a pile of these things this morning. They are made by Odetics in Anaheim Ca. After I got home with them I realized that they are for the space shuttle. Does anyone know anything about them? I THINK they use a tape drive inside. I haven't opened one up yet but I saw the remains of a tape drive at the same place and I think it was the guts out of one of these. Joe

VAX 8550 & DEC available

by jwest＠classiccmp.org

I didn't want to post this, cause it wasn't on-topic & all according to some...Would someone be interested in a early 80's VAX 8550 w/peripherals? If someone is interested in the below please contact me off list. I may be interested in the TU/A81. I'm guessing from the sound of it that he doesn't have the computer console for the 8550. Jay West -------------------- I got this unit (and the others soon to be described) from a liquidation. Right now, I am more interested in moving them than making money on them. I would greatly prefer that someone pick them up rather than ship them but I will accommodate any type of shipping. Digital TA81 Digital TU81 Digital VAX 8550 Digital H8C40 SC008 - AC 64AMA-YE There are a few more items but I cannot find a serial number on them. They are cabinet-like like the VAX. Although there is one monitor, everything else is cabinet size. That means no manuals, disks or software that I can see. I haven't really dug into them to see what's in them. Everything is located in Chattanooga Tennessee. Thanks for the help. I would much rather a collector get these than selling them for scrap.

Manual TEAC MT-2ST

by birs23＠zeelandnet.nl

I just acquired a TEAC MT-2ST tape drive with an Genoa System QIC-02 ISA 8-Bit Adapter and was wondering if anyone here perhaps had a manual for either the card and/or the drive itself ? For your information, this drive is 5,25" in format and takes normal cassettes, thought it was a pretty nice find.

Yes, I am a perpetual lurker (was: RE: is it just me ? :-))

by dzubint＠vcn.bc.ca

My personality is that of an introvert, so I tend to lurk here and "in the real world" too (I'm the quiet one in company meetings). I think I last posted on this list a couple of years ago (until today anyway). For the record, since I didn't respond to the previously mentioned age survey...I'm 42, married, got my B.Sc. in Computer Science in the 1980s, and I have a collection of VAX and PDP-11 systems in my basement that I power up regularily, and a random bunch of Radio-Shack, Commodore, and early IBM-Compatibles that I power up a few times a year, as well as a SIMH HP2000F system that I love to tinker with since it was the first system that I ever worked on back in the 1970s. (I'd love to have a "real" HP2000F, but I think my wife would object to any more stuff in the basement... SIMH & TS10 are a big help there) ...and I'm currently on a Mac mini running OSX 10.4 telnetted into a SUN system and using PINE to email this to the list!

mouse nipples

by julesrichardsonuk＠yahoo.co.uk

The mouse cursor on this laptop (an aging Thinkpad) keeps on moving by itself - presumably the hardware side of it's the same on all laptops with a mouse nipple though. Anyone know if it's worth me trying to get underneath the keyboard to fix it (I assume it's a dirt-related problem) or is the problem more likely to be some sort of obscure software issue? (I have no idea when mouse nipples first appeared on laptops, but I imagine they're on topic just :-) cheers Jules
