Well, I haven't tried taking it apart either, but it may be worth mentioning specifically that when you put the clear "sleeve" back into the drive, it almost certainly releases some kind of catch which allows it to lock onto the "cd-holding-insert-thing" and pull the whole thing back out. I would try to find that catch, which is most likely off to the one side or the other (just a guess, since that's probably where I'd put it...), or directly above or below the disk. (like built into the spindle that turns the CD somehow...) If you can get to it, and release it, you ought to be able to pull the disc out. Otherwise, yes, the caddies are kind of difficult to find, but I have two (one for each drive), so you can probably get them.

I saw this on another list, thought there might be interest here. On Mon, 15 Apr 2002, Douglas A.

When? I could really use ethernet support for the PDP-11 version of SIMH! BTW, how does the speed of the VAX version compare to real hardware? Zane

HP old computer

by mcap＠ns.sympatico.ca

I am looking for the specs for a Hewlett Packard Vectra Vi series 4 5/90 computer. Someone gave me this machine which works fine however getting the darn thing open so I can install a cd rom is another matter. Its like a vault or something. If anyone can find specs for this computer could you please email me the URL to fenwick(a)ns.sympatico.ca Thank you Robb Fenwick

Need Burroughs Tape Spec's

by jrkeys＠concentric.net

UPS delivered my Burroughs tape unit model BU4180 yesterday but it was destroyed. They must have dropped it from a high place as this thing weighs in at almost 80 pounds. Things inside are pretty bad but I would like to try and get it looking nice again, since the boards inside are damaged I do not think I can get it to work again. Does anyone on the list have repair manual for this model? I would like to see how he belts go around the pulleys inside the case. Thanks

BIE model 4410

by pat＠cart-server.purdueriots.com

Does anyone know what this is or want it? It looks somewhat collectable... I'm asking $25 for it, that's how much it'll cost me for the switches and LEDs if I build my own frontpanel instead of re-use this one's. Here's a description, pictures to appear soon on http://purdueriots.com/imgs/ called bie*.jpg >From the date on the back, it looks to have been purchased in '78 or '79. It's a 6800 based system that I picked up at Purdue Salvage for a couple $$. It has 3 IO cards each with a 6821 on it, a MPU card with a 6800, a ROM card, a front-panel card and some other card with (i believe) RAM of some sort on it (chips are Intel P5101L's 22pin DIPs). Front panel has 24 toggle switches w/LEDs (persumably for the IO), a 6digit 7seg display labeled TIME, 7seg labeled FAULT and a pair of 7seg's labeled STEP. On the right, a 2x6 matrix of pushbuttons labelled 0-9 and a pair labeled "S". Next to that, a 2x6 matrix of PBs with LEDs next to them, labeled: STEP BRANCH STEP NO. PROG. START INST. TIME ABORT MASK OUTPUT ABORT ON/OFF INPUT MASK ABORT STEP NO. INPUT ON/OFF CLEAR STEP Along the bottom, there's a row of switches, left to rigth: POWER: Red push-on push-off square switch AUTO/MANUAL: SPST keyswitch EXAM LOAD/RUN: SPST keyswitch PROGRAM: Set of four 'interlocked' buttons (only one is set at a time) 1-4 START: momentary PB RUN, HOLD: interlocked PB's JOG: momentary PB RESET: FAULT, SYST: momentary PB, ALARM: push-on/push-off ABORT: momentary PB The case is rackmount, about 5U or 6U. On the back: 50pin "Amphenol" scsi-style connector. Connected to three IO cards. Power inlet, outlet, fuse SONALERT beeper.

Electric ovens work best for this since gas ovens produce tons of moisture. Trouble is, many ovens can't go low enough (~200F or so). I've had good results from sitting stuff atop floor-mounted heater vents in the winter. This obviously works best when the equipment in question has air vents. Over the past ten years or so, I have gotten a *large* quantity of equipment (literally hundreds of computers) that has been out in the rain, sometimes for months. Some of it I use daily even now. Computer stuff (except for floppy and hard drives) tends to deal with it fine, even monitors. Analog stuff like test equipment tends not to fare so well, nor does mechanical stuff like scanners (though my main scanner was indeed out in the rain for about a week; after a little TLC it performs flawlessly). The water doesn't seem to do any harm at all, even with long-term exposure...it's the crap that the water can carry into the equipment, and sometimes corrosion later on. -Dave -- Dave McGuire "Hush and eat your vegetables, young lady!"

Looks like tin "rust".

I use Alconox, a trisodium phosphate based cleaner that's very effective. I have a big pile of acid brushes...those little pencil-sized brushes that go for about a dime a dozen. I think they came from MSC, but I don't recall for sure. Their bristles are about 1" long by default, but you can easily trim them down to make them much stiffer. They're good for scrubbing stuff like that...similar to a toothbrush but easier to deal with. -Dave -- Dave McGuire "Hush and eat your vegetables, young lady!" St. Petersburg, FL - Mr. Bill
