I have a an 8f so they are somewhat different but the fans blow in across the cards. The PS in the reaw with its own fan. The 8e has the power supply down the left side(facing the front from front) and thefrom right (input) to left (out through the PS). The power supply will tolerate higher temps if memory serves than core. Keeping the core cool and at a relatively constant temp was the key to stable ops. Allison

Hi Dan, At 11:20 PM 11/12/01 -0500, you wrote: > From the Classic Computer list: > > > I've had to dispose of all my classic computer stuff > >What? What happened? Pressure from the OL and I just got fed up with everything. > >You were my HP hero! You had all of the vintage HP gear >that I'm trying to collect! Well there's still a pile of the bigger and less popular HP stuff here if you want to come get it. Here's a list of what I can remember off the top of my head: Complete and working HP 150 and Touchscreen II systems with drives and manuals and SW, etc; a lot of HP 110s, again with manuals and SW; about 20 HP 9825s with loads of accessories; about 15 HP 85s again with loads of manuals, ROMS, etc; several HP 9920s including a full blown and loaded one that came from Litton Laser Systems; several 9826s and 9836s including a 9836CU; and bunches of interfaces and peripherals for the above. Also a dead 9830 and a dead 9821, parts of a 9835, several 9845s and at least two HP Integrals in unknown condition. Also a working HP 120 CPM machine with SW. But I don't have time to ship them so you HAVE TO come get them. I haven't decided what to do about the HP 9915s and the 9831 yet. All of the following are gone: ALL of the HP handheld calcs; all the extra HP SW paks and manuals; all the HP catalogs; all of the HP Journals; the HP 9100 and accessories; all the HP 97s, 9815s and small desktop calcs; the HP 125 CPM machine; all the AIM 65s; the Apple Lisas; the DEC 11/23 system; all the S-100 stuff except for a few Cromemco cases with backplanes; both Altairs; the Rubicon; the SB-180; all the HP 9000 series 300 machines; all six Osbornes; both Z-100s and all the manuals and extra parts; all the Intel and Motorola SBCs; the Tektronix 31 calc; the Tektronix 8051 computer and all accessories and manuals; the Tektronix CPM computer; the Intel 235 MDS; the Sony/Tektronix Logic Analyzers; the Dolch MPM computer/logic analyzer; ALL the general computer manuals and books; all the test equipment except for one OLD HP logic analyzer and all the machine tools and tooling except for the 12 x 48" lathe (it's spoken for but we have to tear down the building to get it out!)

Too true, again. I blame whoever decided IDE hard drives were good to shoehorn into any system ;) (Maybe that was apple?)

No, I think that /dev/hd2 and /dev/hd4 still have all the original files. There are binaries for ls and others there, but when I try to run them I immediately get a succint "killed" message.

Anyone got a spare QBus VAX CPU (and/or DELQA)?

Hi, I'm sat here in my room at home looking at a completely empty BA23 and thinking - I should get this up and running :&) I have another BA23 that's up and running with a MVII (KA630+8M board) and I was thinking another KA630 would make this BA23 into another operable machine :&) If someone in the UK has any spare Qbus bits laying around... :&) On a slightly more urgent point - I'm in need of a DELQA (or a DEQNA(?)) for my MVII - I can probably get away without a cab kit and manufacture something myself - I've got a spare ethernet transceier and a couple of 15pin D sockets (from old ISA IO cards, when they came with a game port :&) I'm happy to pay postage in the UK - might even stretch to a pickup if it's not too far from manchester :&) (oh - and I'm probably in london mid december sometime for a day) -- Matt --- Web Page: http://knm.yi.org/ http://pkl.net/~matt/ PGP Key fingerprint = 00BF 19FE D5F5 8EAD 2FD5 D102 260E 8BA7 EEE4 8D7F PGP Key http://knm.yi.org/matt-pgp.html

I've got a PTC 2KRO with some white/gold 1702s in it... with some kind of monitor, haven't plugged the board into the SOL to see what they are... I was afraid they'd end up at an address that would keep the SOL from booting. I wonder if my Needham burner can read 1702s? -dq

Cat the file to see what's in it, then use echo to put modified versions of the lines you need into some other file. > /mymnt/hd4/etc/security/passwd and opasswd exist, but they > are in a totally unknown format--anything like unix. What does a line in each of those look like? Normally etc/security/passwd contains lines with username, encrypted password, lastupdate, restrictions (if this is null, it means "none"; alternatives are "nologin" and "nouse"), and a field describing audit classes used for accounting. /etc/security/passwd is roughly the equivalent of the /etc/shadow file used by other UNIXes, not the equivalent of /etc/passwd; opasswd is either an older version, or the original /etc/passwd before it was converted to use shadowing. It might be worth trying to rename them or move them somewhere else, then replace /etc/passwd (move the original somewhere else) with one containing a null field instead of the indicator (usually 'x' in UNIX but '!' in AIX) that tells AIX to look in /etc/security/passwd of the password data. So you end up with an /etc/passwd that has a line like: root::0:0::/: instead of root:!:0:0::/: > Could I replace a known encrypted (that is, under another unix > variant) password in the corresponding token? I can't remember if AIX of that vintage used the same algorithm for encrypting passwords. I think so. But I think it would be much easier just to null out the password field (in either /etc/passwd or better still in /etc/security/passwd). If you can then boot the system properly and log in as root with no password, then you can set one in the normal way. -- Pete Peter Turnbull Network Manager University of York
