Hey all -- Picked up an HP Integral PC. Probably paid too much for it but something about a luggable HP machine with a plasma display running HP-UX from ROM seemed irresistible. But I digress. Has anyone archived the manuals for this thing? I've been unable to find anything in my searches on the internet. Found some software archives (and after lubricating the floppy mechanism I've been able to make use of it...) but not much documentation. Docs for the HP BASIC for this machine would be nice, too. I've only played with it for a little while, but it seems like a really neat machine. (Though it seems like this thing is just begging for some sort of mass-storage other than the internal floppy and RAM. Anyone have an HPIB hard disk for sale? :) Thanks, Josh

Different take on 10 Yr. 'RULE'

by dm561＠torfree.net

Date: Sat, 28 Nov 2009 16:49:20 -0500 From: Murray McCullough <c.murray.mccullough at gmail.com> Subject: Different take on 10 Yr. 'RULE' A different interpretation on the 10 Yr. 'Rule'. Many experts, CPU mag being one, say that we shouldn't store info on CDs, DVDs, etc. as they may be unreadable in less than 10 yrs. Wouldn't it be sad if we lost valuable information on the classic computing era? I guess old-fashioned paper is the best way after all! Let's hope these technologies last longer than my Zip-drive and disks that can't be read because the drive died and I can't get it fixed or at the very least at a decent price. So Sad! Murray-- --------------Reply: Only sad if you want it to be... No problem finding a working ZIP drive for free or next to nothing these days; all kinds of them on eBay at .99 with no bids, or just ask on the various forums and I'm sure someone'll be happy to get rid of one. Never had any problems with my drives or disks, FWIW. m

Ancient 3com switch

by mark.kahrs＠gmail.com

I don't know if the 10 year rule applies here, but I have a old 3com switch (3c3500) that I'd like to use. Problem is that the previous administrator was competent and changed all the passwords. So, how should I reset this unit? Mind you, there is a socketed flash SIMM ... Any ideas? There's also a bad SRAM chip, but that's another kettle of fish.

Wanted - HP16530A docs, HP-HIL keyboard/mouse/PS2 adapter

by classiccmp＠philpem.me.uk

Hi guys, I've just got my hands on a HP 16500B logic analyser mainframe, complete with a few acquisition cards (16530A 2-channel 400Msps oscilloscope and 16550A 100MHz State/500MHz Timing logic analyser). Now I'd rather like a keyboard and mouse for it... I'm aware that the HP-HIL keyboard and mouse used on the 16500B were HP-proprietary, and that they were also used on a couple of HP workstations. My question is, does anyone here have a HP-HIL keyboard, mouse, or (preferably) a mouse and keyboard pair for sale? (I'd also settle for a PS/2-to-HP-HIL adapter, if such a beast exists) I've had a quick look on Greed-bay, and it seems the only listings for HP-HIL kit are from test-and-measurement dealers whose prices are a bit... well... "out there". I could also do with the manuals for the 16530A oscilloscope card; at the least I need the Front Panel Operations Reference, but the Service Manual would be good too. I can't say I'm too fussed about the Programmer's Manual (it's on Agilent's website as a PDF), but it would be nice to have a complete set. I'll take PDF, (good quality) photocopy, or dead-tree, whatever's easiest. Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Is Fido extinct?

by rodsmallwood＠btconnect.com

Calling all hoarders! I have been trying to get my old Fido BBS (circa 1983) running again on my DEC Rainbow. The original Tom Jennings code got trashed in a system crash may years ago. There's bits of it on his BBS but I would need to be a much better C programmer to have a hope of fixing it. There are copies on the old Decus site but the un-squeezer's (NUSQ & NUSQ110) just report errors. I know about FOSSIL but its FIDO_DEC.exe I'm really after. Does anybody have or know where FIDO_DEC.exe might be found. Rod Smallwood

Wire-OR is fine until you need to find out which signal is driving the input low, or should I say to logic '1' (my machine uses -6.3v = logic 1, 0v = logic 0). You need to isolate all the outputs to check them, not TOO hard on a wire wrapped machine but must be a swine if you've soldered everything together. Of course there still the other problem, if you need two or more wire-ORs from the same output, you need to buffer the outputs separately or generate the signal two or more times.

old simtel contents

Does anyone still mirror the old Simtel archives anymore? I'm in need of msdos/arcers/extar10.zip among other things. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Apple II Europlus keyboard

by laurens＠daemon.be

Hello everyone, After a long time, I've booted my Apple II again. However, it seems that some keys on the keyboard are not always working. I can get some to work by pressing quickly & hard a couple of times. Before I'm going to pry open the keyboard, is it "normal" that these keys don't seem to make contact? Also, I forgot the name of the recently discovered old case cleaner material, does anyone know this? Thanks in advance!
