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

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!

HP Journal Jul 1980, (whole issue dedicated to the HP-85). HP Journal Dec 1982, (article on the HP-86/87 memory architecture).

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.

I know my dad would not like to see them trashed, and they would help to cover his bills. Thank you for your help. Sincerely, Paul

Egregious VMS newbie questions

by TRASH3＠splab.cas.neu.edu

well, since the major questions have been answered, here is my two cent's worth. Yes, most of the startup stuff is in either SYS$MANGER or SYS$SYSTEM, but at least on the systems I run (5.x and 6.x) the best logical is SYS$STARTUP, as it appears that just sometimes things get put in SYS$SPECIFIC and sometimes in SYS$COMMON, and if you always use SYS$STARTUP, then the logical path to search will always be the same. Of course, you may not want to learn too much of this if you are going to the "other" operating system. Joe Heck

Egregious VMS newbie questions

by jpl15＠panix.com

Thanks to Mr. Finnegan - I have a nice VAXstation 3100 Mod 38 running Hobbyist VMS V7.2 - sitting here whirring away. As I observed to him - it's interesting to have a DEC machine in my collection that weighs *less* than I do. So now my untutored Quesions am: Can this be done: VAXstation --> Ethernet -->[???]<-- Ethernet <-- cablemodem <-- the Net. What adapts Thin Ethernet coax to Cat5? More specifically to download/install freeBSD perhaps... And, furthermore: MY VMS experience was sketchy at best, mostly desultory playing with a uVAX II that Hans now has - and I have no doc at all right now. What is the system called that VMS uses to chain all the DCL commands to auto-execute at startup? I wanna edit a lot of them out - especially right now it's looking for a cluster it can't find, and periodically (every 15 mins) complains of "too few servers". Thirdly/finally: Anyone got a VMS Grey Wall they'd like to unload cheap? I'll pay for the books, packing and shipping to zip 89706 (Carson City, NV). Cheers! John

Thanks for all the VMS info!

by jpl15＠panix.com

Thanks all who have given me so very much Good Information - hours of fun! It's a good thing that I had a bit of prior VMS exposure... of course the thing that becomes apparent is that I'd like to get some actual programs running, as opposed to just mucking about with the OS, however I enjoy that too... I'll figure the Ethernet connections out - and since there is a functioning telnet client that I've already run... I'll get NetBSD or some flavor of some *ix.... Also I downloaded all the pinouts and cable connections, so I'll also have to get a graphics monitor attached - after I see if I've actually got a card of some kind installed... Thanks again to all, and I'm sure there will be a few more [(few)exp10] questions but I seem to be in the right place for that... Cheers John

C64 game??

by julesrichardsonuk＠yahoo.co.uk

Got this from a chap the other day: "When we had a Commodore 64 some time ago there was a game on it that involved a little plane flying over some buildings i think and your plane then tried to level these to get to the next level of the game. Can't remember what it was called and if posssible we would like to buy a copy of the game for our computer now." I remember the darn game - one of my friends had a C64 and I used to spend hours round there playing it. The graphics blew those of the speccy I had at the time away :-) I just can't remember the name! I seem to remember flying left to right and dropping bombs on buildings, whilst shooting down enemy planes flying in from the right. I assume this is the game the guy's talking about... Anyone recall the name for me? cheers Jules

I've seen a couple of threads discussing the need to program 1702s. If anyone needs a small qty of 1702A programmed I can do this. I've got an old 1702A programmer that I use to program EPROMs for my MMD1. The programmer is Tenor Model 763 - it was used originally to program sequence ROMs for industrial control. I've repaired it and made some modifications to it, it's a manual programmer, you enter each byte on toggle switches, originally the LS bit was on the left, MS bit on the right, I reworked it so the bit order was more normal. :) -Neil

m4 data 1/2 tape drive woes

by jwest＠classiccmp.org

Well I just confirmed my suspicions by hooking the m4 (9903) drive up to it's original system (a General Automation Zebra 2820). The MK2 SCSI board in the M4 data drive is "faulty", the controllers don't see it. I hate to go in search of a new 1/2 SCSI tape drive as they are pretty expensive. My M4 is (comparatively) light, and was little used and in gorgeous condition. So, what are the chances someone may have a "256K MK2 SCSI" board for an M4 Data 9903 tape drive? Or know where I might find/buy one? Thanks :\ Jay West

Anyone here familar with Motorolda PowerStack computers?

by rigdonj＠cfl.rr.com

I picked up two of these yesterday. I searched the net but didn't find much information about them but I did find enough so that I know what they are. However one of the ones that I have doesn't have the rounded top. Instead the top is flat and it has a rectangular opening in it and a circuit board sticking up into the opening. It looks like it was made for an expansion chassis to mate with. Anybody know more about that? Joe

NEC APC III diskettes?

by d_cymbal＠hotmail.com

Nope, actually the APC III has 5.25 drives. The original APC had the 8" floppies. >From what I googled the APC III is using quad density 720kb floppies. It ran a modified OEM'd version of MSDOS 2.11. Also apparently there was PC/UX a System III derivative available from NEC at the time. Alas, I've yet to find images of either to this point.

Anybody here using the old (relatively) Baynetworks Baystack Instant Internet 100? Mine uses version 7.00 firmware and software and was wondering if anybody had the firmware and software 7.20 for this unit. I got mine secondhand from a friend and you need a buisiness acount with Nortel (who purchased bay networks) to get newer software then 6.0.

M4 data tape drive with scsi option

by jwest＠classiccmp.org

I have an M4 Data tape drive, with the MK2 256K SCSI option board in it. I am trying to use it with an adaptec 2940UW controller (off the 50 pin connector) and the card doesn't seem to recognize the drive. Guess it's possible the drive is on the fritz, but it was in pristine working shape when I put it on the shelf (was my office demo unit, little used). So, I am wondering if anyone has one of these, and what type of PC controller they were using? Hey, it's classiccmp related, trying to cut some tapes for my HP2000 :) Jay

What are these for? 24 Mb disks

by rigdonj＠cfl.rr.com

Another of today's finds. Two "Verbatim 24Mb High Capacity Flexible Disk Servowritten and Verified 78 Sectors per Track 666 TPI". These have a hard plastic shell with a shutter. I thought at first they were MO disks but they're thinner plus the capacity is a lot less. I haven't figured out how to release the shutter so I don't know what the media looks like. One disk is label "Restricted Rights Encore Computer Corporation". It used to have somehting typed on the label but it's all faded now and it's too faint to read. I've never seen these before. Does anyone know any more about them? Joe

HP 9111A tablet

by gvsher＠netzero.com

Hello, I saw your query on a web search for the 9111A. I worked in the HP factory where these were made and they were a high-quality piece of equipment! It's too bad that HP doesn't support it now. Some 9111A manuals had example programs for the 85A and other GPIB system setups. The 9111A was used with the HP300/9000 computers and EGS, which was quite a powerful CAD system in its day and you can find some of these systems still working. The HP EGS software was written in Pascal. The HP86B had a software program that would use the 9111A tablet for some drafting work. And it would plot out a tablet overlay, similar to EGS. It was called the "Series 80 9111A Tools, Graphic Tablet System, HP-86/87 Editor" and I still have a single-sided disk here that was usable on the old HP 9121 3.5" dual-floppy drive. I also have a disk of the 9111A HP85 System Tools, but I don't know if the disks are still good. I might have the HP85 tools on a cassette also. My HP86B died and so did my two HP85s. The HP86B might still work somewhat, but I haven't had time to fix it. The advantage of the HP86B and the HP87 were that they had larger screens than the HP85, so you could see a drawing on the screen better. The 8-bit systems were pretty slow, however, so it made any kind of CAD difficult. One other idea on this is that CEC (Capital Equipment Corp. in Massachusetts) made a GPIB interface for the PC called the IEEE-488 and in their promo literature it gave a GW Basic program for using the 9111A with a PC. They claimed to have used the tablet with an early version of AutoCad but they would not sell a driver and said it wasn't being marketed. It gave some code examples in Basic & Pascal. I've tried to find a PC mouse emulator for the 9111A tablet with no success, but a programmer might write one without too much trouble. The mouse protocol is published in some places. It would require a system with GPIB, or a GPIB to Serial bus converter like those made by IOtech. You can find converters on eBay occasionally. I've got a file of all this tablet stuff here somewhere and have wanted to do more with this since I own a 9111A and it sits here unused. I used an Appoint MousePen with TurboCad once and thought it worked better than an ordinary mouse device. It has a feel more like the tablet, but having used the 9111A with EGS, I thought it made CAD drafting easier. Some other types of tablets exist out there too and some CAD magazines have printed reviews. Using the 9111A depends on what you want to do. I'm seeing more of a need for a digitizer, but HP made some larger units for that task. The HP7470A and HP7475A plotters can also be used as digitizers with the Digitizing Scope. It was an optical view finder that looked like a plotter pen, only a bit larger in size. You could put a drawing in the plotter and move it around with the direction arrows and press the "enter" button to log a point when you had the Scope over the position wanted. The plotter manuals had HPBASIC example programs to do this. The X,Y data could be stored in arrays and printed out or stored on disk or tape. If you find out anything more on the HP9111, I would like to know what you find.

PDP-11 QBUS module ordering in BA23

by chrisc＠addpower.com

The pieces are all coming together on my PDP-11...I received my SCSI card today and am waiting on the memory. I've been doing some research into what order to insert the cards into a BA23 -- this is what I've come up with. Any suggestions otherwise? Since I haven't seen the QRAM-44B yet, I'm not sure if it's a half height or quad height board. If it is a half height, do I need a bus grant continuity card in the CD portion of that slot? Starting with the 3 Q/CD slots on top, then the 5 Q/Q slots: |------------------------------------------------------------------ | M8190-AB (quad height) | | |------------------------------------------------------------------ | Clearpoint QRAM 44B | M9047 ??? | |------------------------------------------------------------------ | M8020 (DPV11) | M9047 ??? | |------------------------------------------------------------------ | Viking SCSI | M7516 (DELQA) | |------------------------------------------------------------------ | | | |------------------------------------------------------------------ | | | |------------------------------------------------------------------ | | | |------------------------------------------------------------------ | | | ------------------------------------------------------------------- Thanks, everyone! Wish me luck configuring the sucker... Chris

BOUNTY: Looking for Koby Electronics HS300-01 power supply

by vcf＠siconic.com

I'm renewing an old bounty. I need to find a Koby Electronics HS300-01 power supply circa 1986. A technical manual would also be relevant. This was including in a product made by Interand Corporation out of Illinois. The relevant feature of the power supply is that it would "monitor a network in a low power mode and 'wake-up' if there was activity". Since this is not generally the function of a power supply, it may be that the power supply had some sort of sensing circuitry to monitor a data connection and then fully power up when it sensed activity. If there are any other products circa 1986 that fit this description then that would also be relevant. The timeframe for this is very short: I need something by Monday for my client. If this rings a bell with anyone then please get back to me. I'm paying a bounty for solid leads. Please contact me directly if you've got anything. Thanks! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

PDP-11/40 success (sort of)!

by ggs＠shiresoft.com

After the better part of 2 weeks I've finally gotten one of my PDP-11/40's to execute some code. Both initially exhibited frustrating similar problems. Both were stuck in "reset". This was because the processor was seeing AC-LO and DC-LO asserted. While the symptom was the same, the cause was different. In one case the power supply was not deasserting the signals. In the other, something in the RK-11D was pulling the signals low. I've worked around both but fixed neither. Once that problem was solved on the "first" 11/40, I discovered that there was a stuck bit when trying to read or write memory. This was temporarily fixed by swapping the data-paths module. At this point I could read and write to memory. Memory could be read and written through the front panel, but execution would immediately trap to location 4 (6 showing on the front panel). This was a "bus error". I unfortunately spent a lot of time swapping memory around (this was not the problem). Replacing the data-paths module with another suitably jumpered one solved the problem and the 11/40 happily runs a little test program. However, at this point I'm hesitant to run it for very long since there is an acrid smell emitted while the system is powered on. I don't want to burn anything up until I track it down. The second 11/40 still traps to location 4. I've verified that the memory is good by swapping memory boards and backplane (I'm using MF11-UP memory) with the first 11/40. I checked the supplies and they seem a little low, but it got late tonight and I'll check and adjust them tomorrow to see if that fixes the problem. It's a bit hard to determine if any one card is at fault because the two 11/40 CPUs are configured very differently (which means there are almost 2 dozen jumpers between all the boards that need to be changed). Here's the 2 different CPU configurations: CPU #1 CPU #2 KD11-A KD11-A Basic CPU KE11-E KE11-E EIS KE11-F FIS KJ11-A Stack limit option KT11-D Memory management I have another set of CPU boards (but no extra FIS) that if the voltage checks don't solve the problem I'll try to see if that fixes it. If anyone has any other suggestions, I'd appreciate hearing from you. -- TTFN - Guy
