Nicolet stuff

by dkelvey＠hotmail.com

Hi Bob I'd gotten the hard drive for the Nicolet but not had time to fiddle with it. I'm currently redoing my code for the floppy drive on my Nicolet. I have a couple disk platters that should be able to be used for the hard drive ( and one that had a head crash ). I'd cleaned up the heads on the drive and with the new disk, seems OK. I've not fiddle with it since though. I was wondering if you'd like to fiddle with it on your Nicolet. You could barrow it for some time and install the demon code on it. On a separate issue, when I'd gotten my Nicolet, I had 2 failed ICs. One was a 7474 and the other was a DTL with expanded input ( I swapped a location that didn't need the expander input and use a TTL there for that part ). I just got started again and found the address wouldn't increment. After some frantic trouble shooting ( knowing it was Saturday and most places would be closed tomorrow for parts ), I finally traced it to a bad 7404. It is not easy without an extender card. I'd attach a couple wires to locations I wanted to see and stick the card back in. I must have pulled an inserted two of the cards 30 times. I hope is wiped the connector pins good and clean. If you should decide to make an extender, I'd split the cost of the boards with you. I think it would be easy to make three separate extenders and put a rail across them to hold them together. It wouldn't be too bad to just have the three separate ones and be careful connecting things. I believe they are just three 100 pin connectors, like S100 boards use. Dwight

M4data model 9914 tape drive

by shadoooo＠gmail.com

Hello, I'm repairing an M4data 9914 tape drive. After fixing some problem with psu, replacing the roller rubber with a cut of tubing, cleaning mechanical parts, oiling some pulleys, now it starts up on power on, runs diagnostics, but unfortunately ends with a **BIFF error (scsi interface). The drive hasn't been connected to a pc via scsi yet. I have a couple of questions: - what should be the correct external diameter of the rubber roller? - where could I find schematics? thanks Andrea

RA81 removal

by jnc＠mercury.lcs.mit.edu

> From: Johnny Billquist >> I compared the DEC part numbers on the RA81 slides and some RL02 slides >> I have, and ... they are indeed the same part number! > What? That can't be. They are physically different. All I know are the following facts: - I bought a group of surplus RL02 drives from a scrap dealer, and they came with slides with the following part #'s: 1213686-00 Rev-K1-R and 1213686-00 Rev-K1-L. (BTW, I have extra -L's, if anyone needs them; will trade for something useful.) - I bought a machine which had previously belonged to DEC in Vancouver, and it came with a couple of RA81 drives, and they had slides with the following (identical to the above) part #'s: 1213686-00 Rev-K1-R and 1213686-00 Rev-K1-L. The two slide sets above are completely identical in appearance; the only difference is that the part # is in different places on the two. - I was given an RL02 drive a while back, and it came with slides, but they don't have any part #'s that I can see. They look almost identical to the ones above, except that the newer ones have two rocking trip levers (one in the middle, and one at one end), and the older ones have only one (the one in the middle).

Flexi-bit PUNCH

by healyzh＠aracnet.com

I'm not in the habit of bringing my photography projects here, in fact this might be a first. I'm hoping someone might recognize this, or at least have an estimate as to when it was made. I'm guessing somewhere between the 1950's and 1970's. Google is useless, the only thing it found, when I looked, was this photo, twelve minutes after I'd posted it. http://www.flickr.com/photos/zanes-photography/16504361399/ Zane

HP 9100B not functioning after shipping. Suggestions welcome

by dfnr2＠yahoo.com

Hello, I recently acquired an HP9100B which was working before shipping, but on arrival does not respond. The fuses are intact, and I can hear the power supply humming on power up, but there is no CRT output, and I cannot activate the error light (for example, by STOP-CLEAR-/ to get a divde by 0 error.) The register label backlight also doesn't light, but apparently did not light before shipping, when the calculator otherwise worked. I have Tony Duell's excellent schematics, which I'm grateful for. I also have a service manual, and plan to go through it, but it seems a bit short on theory and detail. I'm not in position to swap out boards. I haven't been able to check it out in depth yet, but this week I will be able to spend some time on it.? I have, however, done some basic inspection, and reseated whatever boards are accessible without a screwdriver.? This didn't help anything.? I didn't hear any rattling from the CRT, but haven't yet pulled it out to inspect it. My plan is to start out by checking the power supply voltages, clocks, and move on from there. However, since apparently something changed during shipping, I'd be interested in any suggestions that would help inform a smarter investigation. I am hopeful it's not the CRT, as I would expect a bad CRT to not interfere with the error light. Any suggestions or guidance would be very much appreciated. Dave

date representation standards before ISO 2014 and ISO 8601

by spacewar＠gmail.com

In a lot of contexts that predate widespread adoption of ISO 2014 and ISO 8601 (and their relatives), I've seen dates represented in a form such as "02-MAR-79" or "02-MAR-1979". This is similar to the RFC 822/1123 date format, except that those RFCs don't use a hyphen between the components, and use mixed-case for the month. Was there ever an official standard defining such a representation?

HP 7970E mag tape brackets

by jwest＠classiccmp.org

I was just informed that the "new manufacture" mounting brackets for the 7970E are ready. I saw them at about 90% of the fabrication process being complete and they looked really good. Today I'm going to stop at the hardware store and buy a set of bolts/nuts/washers that match the originals (got them there before so I know they have the right ones) so that I can ship each one with a baggie of the "right stuff". I will probably have them shipped out to the people that wanted one by the end of next week-ish. If you were one of those people that confirmed you needed one or two, please email me your shipping address. Best, J

How to save two Mitsubishi M2896 drive (spindle motor smoked!)

by enrico.lazzerini＠email.it

I have a couple of 8" drives Mitsubishi M2863 slim type that I recovered I think around on 1990 both in excellent conditions with which I created images and written several floppy disks 8". For some reason, including my incompetence, both their spindle motor do not run any more. And powering correctly with only +24Vdc the circuit part of the engine rotation control of the disk (called spindle motor) begins to smoke near a chip LB1620. The schematic contained in the maintenance manual of the drive includes components of other different model of spindle motor circuit. If that were possible, how could I to be able to run the drives correctly: reusing partly engine or even replacing it with analogous maybe even creating handcrafted a motor with pieces of recovery and manage the number of RPM (I think 360rpm for 8" drive) possibly with special circuit ? At this moment there is a shortcircuit between +24vdc pin and ground pin.

Passing of L. Nimoy

by c.murray.mccullough＠gmail.com

How can one not be impressed by L. Nimoy's portrayal of Mr. Spock? His character was logical, almost computer-like, but was far more a portrait of humanity than most care to admit to. Ancient/classic computing was a hall-mark of Star Trek and Spock personified that relationship. Murray :)

3.5" floppy failure mode? Hub not attched to media.

Not so much. A 3.5" floppy is recorded at 135 tpi, where an 80-cylinder 5.25" floppy at 96 tpi. On 5.25" Drivetec floppies, the cylinder density is double that--192 tpi. Now consider the hub-clamp mechanism of a 5.25" drive. I suspect that with a bit of care, one can probably get things right most of the time. --Chuck

Brief clip from a 1966 documentary about von Neumann: https://www.youtube.com/watch?v=Po3vwMq_2xA Goldstine presenting while standing in front of the IAS machine, which appears to be decommissioned and in storage. Fuel for the eternal fire: Goldstine seems to be pretty definite in attributing the stored-program concept to Johnny.

I've never had luck reattaching the media to the hub when it becomes detached. (I've used a dab of thin but sticky glue.) I chalked it up to not being able to get the alignment perfect, but it could just be coincidence that my media had failed at the same time.

What resolution should I scan a missing print set at?

Hi all, I have a PDP-11 print set (MP00196, M9301 Bootstrap/Terminator) which is not online. I wish to scan my copy, and donate the scan to all the repositories. What resolution should I scan it at? I looked at a couple that are available as TIFFs, and they claim to be 600 dpi - that can't be right, is it? If it is, no problem, I'm happy to do it at that resolution, but I just don't want to do silly overkill. Thanks! Noel

Unfortunately the picture tube is broken and we are missing the main processing unit. It seems that the display used vector graphics as the horizontal an vertical are identical in design and the normal raster scanning generators are missing. the terminal connected with a 94 pin connector to the main unit, being also fed power though this cable. anyone -- Met vriendelijke Groet, Simon Claessen drukknop.nl

Well, that IBM guy was pretty insistent that it was von Neumann's idea, but that it's one of those ideas that seems so completely obvious when you hear about it that you can't imagine that it hasn't been around all the time. And nevertheless someone had to come up with the thought first. And afterwards it can never be unthought. The "meme" concept actually. BTW the full 55 minutes documentary is on Youtube too.

OMSI and UW FOCAL help

by j＠ckrubin.us

DEC released FOCAL-8 (FOrmula CALculator) in 1969 as a tool for numeric problem solving on the PDP "Family of 8" machines. The language allowed extension and at least two additional versions were made available to the public. OMSI-P/S8 FOCAL is available of Dave Gesswein's site along with an HTML version of the online help as documentation. The manual for Jim van Zee's University of Washington Focal (UWF) is on bitsavers and also as FOCAL8-301 from DECUS. I'm trying to find the missing pieces - an OMSI manual and UWF source and binaries. Can anybody help? Thanks, Jack

Seeking Apollo keyboard and mouse (DN3000)

by ian.finder＠gmail.com

Hi folks, I am seeking an Apollo Keyboard and Mouse to get my DN/3000 all kitted out. There is a set on ebay which I can use as a last resort, but the asking price is a bit steep from recycledgoods. If anyone has a pair available, please let me know. Not opposed to paying or trading for them, but I've grown to dislike dealing with ebay. If anyone has any cool ideas for software to run on it, that would also be appreciated! :) Thanks, - Ian

Z-letter collection

by cclist＠sydex.com

Whilst digging through the detritus of the last 20+ years, I realized that I had copies of Dave McGlone's Z-Letter, issues 1-40 (which is pretty close, IIRC to the lot). Does anyone scan and archive these things for public access? If so, I'll gladly send them along for such treatment. I've also got a dozen issues or so of the TCJ (The Computer Journal) >from 1994-95. Useful or recycle fodder? --Chuck

VT101 8085 CPU Fault

by jnc＠mercury.lcs.mit.edu

> From: Tothwolf > I've seen pushback from some people in the vintage computing community > to wholesale replacement of aluminum electrolytics which are long past > their life expectancy and I just don't get it. Well, notice you didn't cause a big debate on the topic to break out here, as we often get on some of these things (e.g. crimping versus soldering, etc). My _guess_ is that vintage computer people aren't very 'religious' about it, and to the extent that they _don't_ do it, it's as much because they don't have the parts on hand (or the ability to find them easily), plus the work involved, as anything else. For those of us who are basically software people (or even pure digital), this stuff can be a little daunting - not necessarily because it's actually hard, it's just out of our comfort zone. I myself am certainly daunted by the concept of replacing every electrolytic in all the power supplies of all the vintage -11's I've got... (And I don't want to even think about all the filter caps on all the boards! :-) Maybe you (or someone) should offer a service... I'd sign up! :-) Noel

PDP-8fest @ VCF East?

by evan＠snarc.net

Here's something you do not see every day. There are four people interested in bringing a variant of PDP-8 to VCF East next spring (April 17-19). On the PDP-8 front, so far only David Gesswein is registered; others will be soon. It would be very cool if there were LOTS of PDP-8 computers at the show, in honor of the original Straight-8's 50th anniversary. (We invited Gordon Bell, who said he's unable to attend that weekend. Darn.) So: if you've got a PDP-8 of any flavor, and you've always dreamed of showing it off and/or attending a VCF, now's your chance. Paging all the California and Boston people!!!! :) Overall exhibits so far are here: http://www.vintage.org/2015/east/exhibit.php -- we're expecting 30 or so by April. There will also be a dozen or more technical classes on Friday, April 17. So far only one is posted, but we've got most of the others almost determined, and those will be posted soon. Keynoters for the weekend are Ted Nelson (Saturday) and Bob Frankston (Sunday).

Help with old RS/1 files?

by TaylorB＠dnr.sc.gov

I would be grateful for advice on files generated by RS/1, an old BBN software product, about a dozen years ago on a Sun system running Unix. I don't need to use the software, just to read the contents of a few files. It doesn't matter if the format's a mess. If I can see the numbers, I can work out how to extract the information.

I'm cleaning and hunting, so I might find Aminet, too. archive.org contains a full set of Aminet CDs from 1 through 52 (the first two being Walnut Creek) and also Aminet Sets 1-3 and 9, and Aminet Games.

My physical CD of Aminet 3 has different contents to the version on archive.org, and although I can see *what* the differences are, I'm unclear on the *why*. My other handful of Aminet CDs are bitwise identical. At some point I really should figure out how to provide errata and new uploads for archive.org.

HP 21MX Ethernet/SCSI card?

Silly question but I might as well ask. Would anyone have the cross compiler assembler for the HP 85.

ISO: Sun 386i color video/keyboard/mouse cable

by derschjo＠gmail.com

Subject line says it all... From my research this is an oddball cable with a "DB21W4" connector on one end that breaks out into 4 BNC plus a keyboard / mouse connector for the lamentable Sun 386i series (with color video). (Part number 530-1366.) I have acquired one of these machines and have an odd inclination to make it do something... anyone have one going spare? Thanks, Josh

21MX/E FAB

by jwest＠classiccmp.org

In pouring over the documentation for the 13304A (FAB), I find one thing unclear. Is there a way to disable a given block? Empirically, it seems that if you have roms in a given block they are going to get mapped SOMEWHERE, depending on the jumpers and if you don't have roms in a given block you don't have to worry about setting jumpers to disable that block. But I was curious if there was a given jumper combination for a block to disable it - without having to pull the roms. Not a huge deal, just curious, and I don't see it in the docs. Any thoughts? Best, J

VT101 8085 CPU Fault

by robert.jarratt＠ntlworld.com

The terminal controller board on my VT101 is not working, if it displays anything it is random characters. I have used my scope to check the 8085 CPU. It has power, it is outputting a valid clock, but there is no activity on the RD,WR and ALE pins. I am guessing the 8085 is bad, but before I go replacing it I wanted to check if anyone knew of anything else that might cause the 8085 to misbehave (ie am I seeing symptoms or a cause?). It looks to be easy to get 8085s, if I replace it I will socket it at the same time, but would rather avoid having to desolder it if the problem is elsewhere. Any advice gratefully received. Thanks Rob PS Just to check that the rest of the terminal works, I substituted the terminal controller board with one from a VT102 and it worked perfectly. So the problem is definitely on the terminal controller board.

HP 21MX Ethernet/SCSI card?

by johannesthelen＠hotmail.com

Hello! I just got HP 2109 E-series which I bought from eBay last week. I was planning to make own tape emulator interface for it, but I found mystery card from it, and it could solve some of data transfering problems... Here's pictures of it:https://drive.google.com/file/d/0B_DR111cK6W-M0FPSnR4VmRDR3M/view?usp=sh… It seems to be from 1995 what I can guess from chip date codes, but theres no any manufacturers logos. As you can see pic, there is RJ45 and SCSI connectors. Is this somekind of emulator board for disk drive..? Can it used with PC (like old NetBEUI protocol) or is this for some very-special-made-for-very-special-communication-software? Computer itself is from Navy's Radcom station (made by Grumman Aerospace Division), maybe somebody knows more of this system... - Johannes Thelen Old computer blog (Finnish) http://ennenmikrotietokoneita.blogspot.fi/Company site www.thelentech.fi

PDP-8/M restoration project

by blstuart＠bellsouth.net

For any of you who are on more than one of these lists, I apologize in advance for your getting multiple copies of this. Now that I'm moved into the new place and the man cave (my basement) is converging on a usable state and in recognition of the upcoming 50th anniversary of the introduction of the PDP-8, I'm about to embark on a project to restore a PDP-8/M I got a while back. Unfortunately, this one is somewhat incomplete.. So I'm looking to start collecting some of the bits I'll need before it's all said and done. The items I need are in descending order of priority: KK8E M8320 Bus load module KL8E M8650 Async module H851 Inter-module jumper blocks for the CPU boards Memory Storage device and controller Power switch key One front panel switch paddle If you have any of those that you're looking to unload (especially the M8320 or the M8650), let me know. Obviously, I can live without the switch paddle and I should be able to get a new key cut, but if anyone has extras lying around, I promise to give them a good home. The truth is I don't expect to come up with memory or storage devices for what I can justify spending. However, it turns out I do have an Omnibus prototype board. So I'm planning to use that to build a device to emulate a set of RK05s using an SD card for storage, and if need be, I can put memory on there too. Thanks in advance, BLS

VT101 8085 CPU Fault

by jnc＠mercury.lcs.mit.edu

> From: Matt Burke > You need to connect a DMM with mA (or better uA) range in series with > the bench supply and capacitor I was wondering about that - isn't the startup current, when the supply is first turned on, going to be substantial, especially with the larger caps? Any chance that could harm the DMM (or am I too used to old mechanical meters? ;-), or are they pretty well protected against over-current situations? If one does have to worry about this, is there a need for some sort of switch arrangement so that on initial power-on, there's a direct connection (supply -> cap), but once it's been on a few seconds, one can switch to route things through the DMM, to measure current with the cap mostly charged? Again, apologies for the elementary questions, but I'm not a hardware guy by trade... :-) Noel

Old toner

by cclist＠sydex.com

I came across a carton (10 boxes) of Panasonic laser printer toner KX-P450 in my "I forgot about this stuff" stash. This is the toner for the old KX-P4450 series. I still have a 4455, but it's destined for the scrap heap, as it's not any better or more useful than any printer I have now--and is a messy bugger to refill. My question is "Can this toner" be used to refill other printer cartridges?" In other words, is most printer toner pretty much the same stuff? --Chuck

I think people confuse Turbo Pascal with "standard" Pascal. Turbo brought a LOT to the table that you simply coudln't do with a standardized Pascal compiler. Borland never quit tweaking the language - Object Pascal hit with the 5.5 release of Turbo Pascal and that was improved upon even further with the 6.0 and 7.0 releases. When Delphi hit the market in 1995, it really blew people away. Had Borland's management not run the company into the ground, Delphi would be a lot more popular than it is today.

IBM-11 Card Punch

by marc.verdiell＠gmail.com

Great work and cute card punch! Some similarly gifted folks at CHM are just rebuilding an IBM 01 right now, and it's equally cute and minimalist and bullet proof. They tell me it's how you'd re-punch a bad card in a hurry in the middle of a jammed job. I can't resist a shameless plug at my own 029 restoration. Machine discovery and hauling back from Kansas to California courtesy of Carl Claunch, who has been busy since getting the IBM 1130 (and own 029) he brought back into action. But this extra 029 gave me a satisfying, if modest, first electro-mechanical restoration project, from nothing working at all to full up. https://www.youtube.com/watch?v=YnnGbcM-H8c&list=PL-_93BVApb59yIG2RELONEYOzJ 3lMXsqV Marc On Fri, Feb 20, 2015 at 6:10 AM, Dave G4UGM <dave.g4ugm at gmail.com> wrote: > Folks, > Some time ago I bought an IBM Model-11 electro-mechanical punch on E-Bay. > It > was in a bit of a mess as someone had partially dismantled it and not > re-assembled it properly.

Anybody interested in a Tek 1240 Logic Analyzer ?

by elson＠pico-systems.com

Folks, I have a working Tektronix 1240 logic analyzer. It has 3 acquisition cards, one 1240D1 (100 MHz, 9 channel) and two 1240D2 (50 MHz, 18 channel), plus some ram packs and a Z-80 disasm. I also have a full set of probe pods and spring clip lead sets for it. I do want to get a little money for it, maybe $100 plus shipping. Anybody interested? (I have a much fancier analyzer here, so this has been sitting for some years. The only downsides to it are no net connectivity and the display format can be a bit slow when zoomed out. Also, the memory depth is pretty small. I forget, but maybe it is 512 samples or something like that. my email is elson (at) pico (hyphen) systems (period) com Jon

IBM-11 Card Punch

by dave.g4ugm＠gmail.com

Folks, Some time ago I bought an IBM Model-11 electro-mechanical punch on E-Bay. It was in a bit of a mess as someone had partially dismantled it and not re-assembled it properly. It was also missing a couple of the operating buttons. I have had some replacement parts made, and re-assembled it properly. It now works reasonably well. I have made a short video of it operating here:- http://youtu.be/ogplYeEYzu8 Hope you enjoy this. Dave Wade G4UGM

Pascal not considered harmful - was Re: Rich kids are into COBOL

The academic-tool variant of Pascal, as Wirth designed it, was simply useless in practice, or extremely cumbersome to use because you couldn't design a function which could take arrays of variable sizes as input, you had to declare one function for each size. Hopeless. You couldn't do any real data processing that way. Turbo Pascal, and every other useful variant, e.g. the Pascal I used on a minicomputer, fixed that part, and often added I/O extensions in various ways. In short, they made the language flexible, and thus usable. Then TP of course had that fast edit-compile-execute cycle, a low price, and the super-easy IDE. The learning curve from getting your hands on TP to actually use it was very low. Actually the Turbo Pascal IDE is still the only IDE I like. I don't use any of the modern ones, they are just in the way. But I recently tried the CP/M TP version again, haven't used it since the eighties.. and I still like the IDE. Re-learned it in seconds.

Jim Drew's SuperCard Pro?

by nf6x＠nf6x.net

I have a SuperCard Pro, but I've only experimented with it a little bit so far. I hope that it will let me migrate away from my KryoFlux, as the KryoFlux folks and I have some philosophical disagreements. I mostly use Macs as my modern machines, and I use my SCP with Keir Fraser's Disk-Utilities rather than the Windows front end for SCP. Disk-Utilities doesn't currently provide write support for the SCP, but hopefully that won't always be true. I haven't tried SCP with 8" drives yet, but that's on my get-a-round-toit list. -- Mark J.

Hp 2760 cooling system manuals?

by lenox.joseph＠gmail.com

Anyone have any scans or is willing to drop them in the post for a university? Full story: Back in 2005-2007, Qualcomm gave our ECE department a used Agilent 83k tester (F330t). It's basically sat in pieces because there's been no money to hook it up. Well, now there is some money floating around to make this happen, and I'm the poor GA stuck with trying to dig up I have the service manuals and site prep guides for the mainframe itself, but HP/Agilent (in its infinite wisdom) broke out the cooling unit requirements (as in whether or not we need chilled water or even the gpm) into its own manual! We have the E2760D L/L (liquid/liquid) unit. It looks like the manual # is E2760-91001. Any other related manuals would also be helpful.

Jim Drew's SuperCard Pro?

by jfoust＠threedee.com

I asked about the "DiskVaccuum" two days ago and got no response. That project caused a handful of messages here a year ago, but no more. Any opinions on Jim Drew's SuperCard Pro disk-reading device? It was recommended to me by Cloanto, the Amiga emulator place, for archiving my Amiga floppies. $99, USB on a PC, seemingly nice manual. I'd like it to handle 8" inch drives, too, but it looks like I'll need to ask about that, as they didn't say more than "it should work." http://www.cbmstuff.com/proddetail.php?prod=SCP - John

cost of low-quantity PCBs with hard gold over nickel edge card connectors

by spacewar＠gmail.com

I'm seeking input from the various people that have in recent times made PCBs to plug into old microcomputers and minicomputers using PCB edge card connectors. There are quite a few companies (and coops) that offer very inexpensive PCB fab service, even in low volumes, particular for double-sided PCBs (vs. multilayer). However, I haven't found a PCB fab house that offers any reasonable deal on low volume runs of PCBs with plating of hard-gold over nickel edge connectors. Has anyone found a vendor that does? I was somewhat surprised at the difficulty in tracking down good information on best practices for PCB edge fingers. Several of the PCB companies suggested just using an ENIG (electroless nickel immersion gold) on the whole PCB, including the edge card connector, but that isn't really suitable. According to an excerpt of a draft of the IPC-4522 standard, ENIG gold is typically only 0.025 to 0.05 microns, and is not suitable for edge finger use for more than five insert/remove cycles. (It would be perfectly acceptable to have ENIG, HASL, or tin finish on the rest of the board.) A document from AMP recommends 0.4, 0.8, or 1.3 microns of hard gold over nickel, to withstand 200, 1000, and 2000 cycles before failure, respectively. The IPC-2221 standard suggests three categories: Class 1: 0.8 micron gold over 2.0 micron nickel, for general electronic products Class 2: 0.8 micron gold over 2.5 micron nickel, for dedicated service electronic products Class 3: 1.3 micron gold over 2.5 micron nickel, for high-reliability electronic products. The PCIe specs require 0.7 micron gold over 1.2 micron nickel. I'm perfectly willing to build prototypes for my own personal use using ENIG or even HASL with nothing special for the edge fingers, and be resigned to them not withstanding many cycles. However, if I were to offer a product for sale to other hobbyists, I don't think that would be acceptable. I suspect that the original PCI specs had a similar requirement to PCIe. I estimate that a 32-bit PCI edge card requires about 1300 mm^2 of gold over nickel (counting both sides of the PCB), which works out to a little less than 1 mm^3 overall, which at recent gold pricing would be about USD $0.80 in gold. An Apple II card would probably have a roughly similar amount of gold, while S-100, Qbus, Omnibus, Multibus, etc. cards would require several times that. I'd be delighted if in small volume I could pay less than an additional $25 each to get the hard gold over nickel edge connector, but so far I haven't found a PCB fab comes even close to that. Eric

Rich kids are into COBOL

I love this loop construct. I was just talking to a friend the other day about how nice the GO language is, but I lamented that no one has ever copied the elegance of the single loop verb in COBOL.
