Copper does not dissolve in any common alkalis. Strong detergents (some dishwasher detergents and some industrial detergents) however may damage other things. Don't ask me why I had to re-polish the magenta handles on a couple of DEC boards. > Distilled water can be used in a pinch, > but be aware that the stuff is corrosive. That's news to me, and every chemist I know :-) If you don't have deionised or distilled water handy (the contents of your dehumidifier are pretty good), or your local tap water is reasonably soft, do the final rinse with a tiny amount of a wetting agent (common liquid detergent will do but laboratory detergent is better because it doesn't contain dyes, thickeners, or perfume). Then blow off as much as possible with *low* pressure air, or wave the board around to shake off the excess, and let it drain. That's the equivalent to what photo labs do, and I can assure you that photographic emulsion is far more susceptible to water damage than electronics. The only thing I'd add is that before you start washing, it's worth protecting or removing any labels -- especially paper labels -- that might be damaged. -- Pete Peter Turnbull Network Manager University of York

AMC Multibus cards?

by rigdonj＠cfl.rr.com

Does anyone have any information on ANY Multibus cards made by Advanced Micro Computer? I've been told that AMC is a division of AMD. And AMC's logo looks the same as AMD's. I have seveal DRAM cards, a FD controller and a few other cards made by them and I'd like to do something with them. Joe

oddball televideo problem

by dwight.elvey＠amd.com

Hi Most of these like to use better letters such as the letter B. Try setting things to the slowest baud on the terminal and then you can watch realtime on a scope( like 110 ). Get one of those light boxes. You still might be missing one of the handshake lines that one machine needs that the other doesn't. Get the box with the switches and jumpers. These are in the $20 to $25 range and worth every penny. Dwight > >I have a system that does an "autobaud" when you hit return to log in.

FW: 77/68

by peter.matthewson＠tiscali.co.uk

-----Original Message----- From: Peter Matthewson [mailto:peter.matthewson@tiscali.co.uk] Sent: 14 January 2004 21:27 To: 'andyh(a)andyh-rayleigh.freeserve.co.uk' Subject: 77/68 Andy, Just saw your note on 77/68 from the classic computing mailing list. This made me smile; I can only see about 2 references to it that I can find anywhere on the web. My acquaintance with the 77/68 began when it featured in volume 1 edition 1 of Personal Computer World that I chanced upon in WH Smith in Dewsbury, I think this was round about December 1977. I am not entirely sure it was the UKs first home PC because I recall reading about a 4040 based system described in Wireless World which must have been a year or so earlier. I was so captivated by all this I withdrew all my savings bought the bits and built one, for ?60. The 6800 microprocessor cost ?14 I recall. I managed to get it working, I am not quite sure since I was a 15 year old schoolkid with only a multimeter for test equipment, working in isolation and did not really know what it was that I was building. The main problem I had was with wiring the edge connector, the data bus was in one bit order on the edge connector and the address bus in the reverse bit order, a detail I didn?t understand the significance of initially. It was about 2 years before I met anyone who had any idea what I was talking about. I extended the system with 1024 bytes of ram, built a keyboard and cannibalised an old calculator display for peripherals. And I built a 32 bits per second tone burst modem for storage of programmes on cassette tapes. The monitor program I wrote to drive all this took 256 bytes of memory. Those were the days - he said wistfully. Its still up in the loft. I almost feel inspired to get it out and fire it up again! Regards Peter Matthewson

by tomj＠wps.com

(re: http://www.cathodecorner.com/sonny.jpg) Yes indeed, and I did! Man I wish I had all the junk I bought from there... -----Forwarded Message----- From: David Forbes <> To: Tom Jennings <tomj(a)wps.com> Subject: Re: Would you buy a used PDP-8 from this man? Date: 14 Jan 2004 13:37:17 -0700 Tom, This photo is scanned in from the October 1982 issue of National Geographic magazine, which I just found at the thrift store. It has an article about The Chip, and another about Silicon Valley. Humorous reading. The guy with the bowtie is Sonny Monosson of American Used Computer in Boston MA. I remember you saying that you used to go there now and then in your youth. I remember getting their ads in the late seventies, when I was using PDP-11s in high school and college. I would drool over the possibility of getting an obsolete 11 for home use, but the shipping was so expensive back then. I imagine the power bill would be something to behold also. All I remember about the Heathkit LSI-11 I used at Optical Sciences is that it was slower, instruction for instruction, than the Z-80 I also used. -- --David Forbes, Tucson, AZ http://www.cathodecorner.com/

FA: RTTY books

I just put a pile of RTTY books on E-bay. I know this isn't exactly CC stuff but part of it such as the Digital Group computer used as a RTTY terminal are so I decided to announce it here. If you're interested in RTTY take a good look at "The New RTTY Handbook". It's a real find IMHO. See <http://cgi6.ebay.com/ws/eBayISAPI.dll?ViewSellersOtherItems&userid=rigdonj> I will be adding more books and some RTTY equipment ASAP. Joe PS.

Need help shipping something big from NJ

by vcf＠siconic.com

I'm having a large and unusually shaped item shipped from New Jersey to California. One part will need to be crated and the rest boxed. Is there someone in the Boonton area that can recommend a shipper? I would need the shipper to bring along the materials to crate the item. I would also entertain paying a list member local to the area to crate and pack the item, and coordinate with a local shipping company. Please reply privately if you can help out.

Help fixing a broken RL02

by nbreeden2＠comcast.net

All, I'm looking for any hints or advice on repairing a broken RL02 drive. I have two drives, one is working, the other indicates a fault. The unit with the fault lights the fault light as soon as it's powered up, it goes through it's normal power up cycle (runs the spindle at low speed) and seems normal beyond the fault. All power supply voltages are normal. I've swapped the 'easy' to swap parts with my working unit however the fault persists (swapped the logic board that lives on the top/back cover, the servo board and the unit select buttons). Before I tear deeper into it I was hoping someone might have some hints or experience that will help me. -Neil

Well, if no one else makes a claim, the older smaller capacity drives are usually in demand for amateur radio clubs. I have a reserve here for my local club. As an incentive, most of these clubs in the US are 501(c)3 corporations. You would be able to take these as a tax deduction. Find comparables on a refurb site, save the comparable resale value from when you donate as documentation of a resonable price, and count them as donations at the end of the year. Much of this also applies to older 486 computers. A lot of the software still used on the packet backbone will not run on newer machines. Of course, I am not an accountant, so please verify all of this, especially the comparables bit. Kelly

Flashback to July 1991...

by dwoyciesjes＠comcast.net

While wandering around the hallways here at Yale, I came upon a catalog >from Inmac, dated July 1991. I then proceeded to laugh in a bit of amazement over the prices of some of the items when new, and how much they go for now. Here are some tidbits... Inmac NB/386sx laptop - $3,495.00 - probably made by Compaq, or that's what it looks like at least. 20 MHz, 9" 32 shades of grey screen, 40MB HDD, 2 MB RAM... Iomega Alpha 8" 10MB Bernoulli Box Cartridge 3 pack - $235.00 CDC 9883-1/RM05 300MB disk pack - $839.00 or how about some disk drive filters, from $37.00 to $114.00 Mountain 80MB external tape backup drive - $1,149.95... -- --- Dave Woyciesjes --- ICQ# 905818

Old Commodore 64

by aw288＠osfn.org

Ih ave a fairly old C64 (sn is about 32,000) with an odd logo - a 6 and a 4 smashed together, sort of. There is a picture of the style of machine about 1/4 down the page at: http://commodore.ca/products/c64/commodore_64.htm Every C64 I played with as a kid looked like the one at the top of the screen, with the rainbow logo. When did Commodore switch? On a side note, response for the 2400 baud WE modems has been pretty low (zero, actually). I would rather not scrap these things out, although I may lug a pair over to RCS. I received a little more info: > Seems to me that these were not specifically for secure voice - > they could be used, connecteded to a crypto set like a KG-13, > for uses like AUTODIN trunks.

H960 rear doors

Before I tear deeper into it I was hoping someone might have some hints or experience that will help me. It could be lots of things. I had one like that, it turned out to be a fault on the AC servo board IIRC. I suggest you download the RL01/02 Pocket Service Guide from David Gesswein's site at http://www.pdp8.net/query_docs/query_all.html -- it's fairly small and has a lot of useful stuff in it. It's all I had when I had to repair and realign my three drives (though I did have an original DEC printed copy). -- Pete Peter Turnbull Network Manager University of York

FT in LA, CA ASAP: SGI 4D

by adamg＠pobox.com

I just bought three big SGIs but was only able to make room for two of them. Oops. I'm looking to trade the extra one for a smaller SGI, or for a Sun, a micro, video game stuff, test and measurement equipment, some DIP-packaged 27c160 EPROMs or a hamburger. It's an SGI "Power Series" 4D/something, black with blue trim, about dishwasher size and a few hundred pounds. I don't know if it's currently operable. With appropriate modifications it could probably be a nice coffee table or NFS server. I will deliver in the Los Angeles area, but the recipient will need to help unload, ideally with a forklift, or else with a movable platform we can slide it on to. I need to get rid of it fast before the computer gods destroy it. I hope to hear from someone soon. Thanks! (Also available: Gould 2800S strip chart recorder with 8 or so channels of "DC amplifier" inputs, 19" rack mount by a foot or so high, not too heavy or deep. And a Canon fax machine. How the hell did that get in there? All untested.) -- Adam

The replacement cost would of course be the amount necessary to create a new Digital Equipment Corporation, to build new factories and hire new workers to manufacture new BA123, new original DEC disks and boards, as well as the necessary amount to buy back all designs and schematics and rights from HP, etc. Sue them for that amount and then build the new factories and the new hardware!

CPT 8000

by John.Mustain＠exactsoftware.com

Hi Adrian, I read your posting from classcmp.org which read as follows: Hi folks, Anyone have any info on the subject beast here? In fact, does anybody want one? I've got said twin 8" floppy drive monster here and it doesn't fit in with my museum since it isn't a home computer. It also doesn't have a keyboard, but it powers up and asks nicely for a program disk. All I can find is that CPT Corp were based in Eden Prairie, Michigan, were founded in 1971 by Dick Eichhorn and ceased to exist in the early 1990s. The Babbage institute has a CPT 8000 and the picture there is pretty much what the 8520 looks like. Only it has a keyboard :) The 8520 is an Intel 8080-powered machine, and I only know that because I took it apart. Google searches only turn up people offering a data transfer service, so either there aren't many left or it's just not a very interesting machine! Like I say, free to a good home but it's HEAVY, maybe 50-60lbs heavy. I could sure use the space it takes up and I don't want to put it back in the tip.... I thought that you might be interested to know that I used to work for CPT (from 1980 - 1987) and was there (and worked in production) while the 8000 series was being manufactured. A couple of corrections to your information: 1. CPT was based in Eden Prairie Minnesota, not Michigan. 2. CPT was founded by Dean Scheff, not Dick Eichorn. Dean started the company in 1971, and the original product was a cassette tape base memory add-on for IBM Selectric typewriters (The name CPT originally meant Cassette Power Typing). As you already know, the CPT 8000 series (8000, 8100, et al) was a dedicated word processor. The beauty was in it's 14" portrait oriented screen. This screen was white with black characters and had a very high scan rate (for the day). The 8000 perfectly mimicked a sheet of paper being scrolled through an electric typewriter and was therefore very comfortable for most office workers to use. CPT had other products like the 6000 (a low powered, half screen version of the 8000), the Diskpack (sp? I don't remember how we spelled that shared disk system, the Phoenix (word processing with graphics) and the 9000 series (a low profile replacement for the 8000 series that utilized the Intel 8086 processor. If I dig into my archives I could probably find printed articles and sales brochures, let me know if you would be interested in any scanned images of this information.

I've used it nearly every working day since it was given to me. Later!

The chip was made by HP. Its product name was Capricorn. > is there possibly a modern chip that could be used in place of it ? Ha! The HP Series 80 architecture specifies 4 12V clocks! and 6V logic. However, since we are talking about 20 year old technology, I am sure you can EMULATE an HP-85 CPU using a modern processor. > any help or information would be appreciated First a little self-promotion: lots of info on the Series 80 may be found at www.series80.org, but the most important reference is the HP-85 assembler manual (its in the CDROM collection of the Museum of HP Calculators along with the HP-85 service manual: http://www.hpmuseum.org) I have the HP-86 assembler manual, but I have not got around to scanning it yet. There are a couple of HP Journal articles on the Series 80 (also in the CDROM collection above), e.g. HP Journal Aug 1980, pp. 18-22 (brief discussion of the chip set). HP Journal Jul 1980, (whole issue dedicated to the HP-85). HP Journal Dec 1982, (article on the HP-86/87 memory architecture). HP Journal Jun 1983, (discusses HP-75 which has a CMOS version of the series 80 processor architecture) **vp

Programming 1702s

by dwight.elvey＠amd.com

Hi For those on the west coast, I can do 1702A's on my SIM-4 and MP7. I can use Intel HEX or binaries as input ( or BNPF as files if needed ). If the Data I/O 19 that I just got works for these as well, I'll be able to do them there. I currently do 2708's on my ByteSaver board. I also have some old Intel UPP units but haven't had the time to check them out.

Apple A/UX

by teoz＠neo.rr.com

The last release of apple A/UX was 3.1 that came with my AWS95 machine, before that there was A/UX 2.0 for the IIfx and other machines in that era. What I want to know is was A/UX 1.0 ever released and what systems/requirements did it need to run? Until recently there was very little information on A/UX 2.0 on the web and I still havnt seen anything on 1.0 at all (3.0 is well documented). If it does exists its probably 14+ years old.

BOUNTY: Looking for Koby Electronics HS300-01 power supply

by vcf＠siconic.com

Yet another follow-up: Another relevant aspect of my search is any device that would go into a low-power (or sleep) mode and then activate upon receiving data over a network link. So for example, a printer with a print server that sits on a network and stays in an energy saving or low power mode when it's not doing anything but then fires up to print a document when it gets a request. Something like that. I would need documentation explicitly describing this sort of action. I would imagine there is something relevant with network cards that have some sort of power-on feature when network activity is sensed. This would have to be prior to 1994. Solid leads that I can use will be rewarded appropriately.
