OK... I've taken it apart to have a look... the IC dates are late 1968 - there are a few DIPs and a number of 8-pin epoxy-covered button-shaped ICs all over the innards. The DPM came with a 36-pin AMP connector with 4 wires loaded, two for power and two for input voltage. The power wires go right into a transformer at the back of the unit, leading me to suspect that it takes 110VAC, but perhaps it takes 24VAC. I have not yet powered it up - does anyone have any idea what it would take to fire it up? The nixie tubes, for those who track such things, are 3 Burroughs B-5750 7/8"(?) nixies, with a block next to them for "1", "+", and "-" (3 individual neons). The legend on the front proclaims it to be a "mini-diget dpm". I've never fiddled with a pre-LED DPM, so if anyone knows what voltage it's expecting, I can fire it up to see if it works or is merely a source of nixies. Thanks, -ethan

WTD: Fuse PROM programming algorithms

by dm561＠torfree.net

---------Original Message: Message: 11 Date: Tue, 13 Feb 2007 19:31:14 +0000 From: Philip Pemberton <classiccmp at philpem.me.uk> Subject: Re: WTD: Fuse PROM programming algorithms <snip> TI are nice enough to put their programming algorithms online, I've found a textual description of the NatSemi algorithm (though it would be nice to have the timing diagrams, if any), and I tracked down an old rev of the 82S129 datasheet that includes some info on the Signetics Generic I algorithm. Those three would be enough to get by on for now, but it would be nice to have read and write support for e.g. the Intersil and Monolithic Memories chips. As dictated by Sod's Law, I've got the Intersil linear databooks, but not the logic/PROM/whatever databook. As far as MMI goes, I can't even find a copy of the relevant databook for sale, hence why I asked for scans or photocopies (I'm not fussy about which, and I'm willing to pay for the copying and shipping/postage). Thanks. -- Phil -----------Reply: If you don't find 'em elsewhere, I've got Harris ('78), Intel ('76), Signetics ('78) and National ('77) databooks in front of me. Don't know about Intersil; was looking in the MMI book a while back, but now I can't remember where I put it down at the time (probably the same place as the cordless phone ;). mike

Some uni/college student visited the lab where I work (I'm a technician, not a chemist, and my chemical knowledge is limited other than what I have learnt at work over the last 8 years) a few years ago and decided to clean the runners on the plastic slidey doors (do they have a proper name?) on the side of one of the balances. Naturally, as someone else mentioned, the acetone turned the plastic into mush and the door become tough to open, often sticking, instead of being smooth and easy. Generally, we use acetone to clean marker pen off of glass equipment (eg. volumetric flasks) and for cleaning oil/grease out of the metal cups (we test for fat/oil/grease content in the waste water from factories that send there waste into our* sewers) Getting it back on topic... is there an easy was to determine which computers/peripherals can be cleaned safely with acetone, or similar substances?

Yes, it is probably what I'm going to have to use to recover the Tektronix 4051 tapes that I got from Jim Willing. It shouldn't be to difficult to do something similar with heads that don't move (HP, Apple Tape Backup, etc). Fiddling with the firmware for QIC drives with serpentine recording is more difficult

WTD: Fuse PROM programming algorithms

by classiccmp＠philpem.me.uk

Hi, I'm currently looking for information on programming algorithms for the old fuse-link PROMs (Signetics 82S series, AMD 27S series, National Semiconductor 74S series, TI 18S series, Harris/Intersil 7000 series, Fujitsu 7000 series and MMI 6000 series). Does anyone here have copies of the memory product databooks from any of these manufacturers? I've got the Signetics Generic I algorithm (but not Generic II), and part of the NatSemi algorithm (text only, no timing diagrams), and nothing at all for the others. Main reason I'm asking is because I'm designing a programmer to do the 82S series, and I'd like to make it as universal as possible - i.e. if possible, I'd like it to be able to read and program the other chips too. I'm willing to pay for photocopies of datasheets, or the entire databooks if you'd rather sell the book itself. Thanks. -- Phil. | (\_/) This is Bunny.

Head lock, CDC 9720-500

by drb＠msu.edu

I'm preparing to have several 8" sealed HDA SMD drives shipped to me. They're what Prime called a model 4735 496 MB drive, and CDC called (I think) a 9720-500. If the manual is on Bitsavers, I don't know what it looks like. Is there a shipping lock on the heads of these drives? How to set it? Thanks, De
