HP 9915A (industrial version of HP 85A)

The 85F is a nice catch IMO, you > gain two ROMs and don't use up any of the ports on the back. Yes, the 85F was part of the 3056DL data acquisition system. You can find a brochure with a description of the 85F config at <http://library.hp41.org/LibView.cfm?Command=Document&ItemID=23075> On page 21 you find the 85F described as: Computer with CRT, keyboard, tape drive, graphics, 16K memory, HP-IB card, I/O ROM and ROM drawer (all that for just $3485). There is no Mass Storage ROM and the Adv Programming ROM was a $165 option. Also since they gave you the ROM drawer, the ROMs would not be inside the 85F, so you do use one port on the back. Even the 9915A which contains the ROMs inside the cabinet, has only three slots, so you appear to lose a slot anyway. Also, Joe, since you have the programmable-rom-module, can you check inside to see the type of the translator IC (the one closest to the the edge connector. I would guess that its either a 1MA5-0101 or a 1MB5-0101. Further down there should be a 8048 (Intel microcontroller) that does all the funny address decoding and stuff. At least with most HP85 I/O cards, the funny voltages on the I/O bus are hidden by the translator chip; on the other side you have industry standard TTL. Because of the "funny" voltages on the I/O bus, contructing a programmable-rom-module from scratch would be very difficult, but if we can use the 1MB5-0101 part (which is found in most adapters) we can convert some of the zillion 82937 HP-IB adaptors that appear constantly on eBay to programmable-rom-modules. Then we can all have the EMS ROM and get rid of the ancient (and huge) 9135A hard disks. BTW The most impressive of these beasts is probably the 9895A dual 8-inch floppy drive, that is so big that the HP85 sitting on top looks like a toy. I have a 20 page brochure on the 9915A. I'll try to make it available on-line soon. This is where I got the keyboard connector info I posted in my previous email. gil smith <gil(a)vauxelectronics.com> wrote: > There are still a few unknown keys in the main > matrix though. Pin 25 use is unknown (2.5V). Pin 1 is chassis ground.

Have a look at page 5-3 of the HP-85 assembler manual (available on CDROM from the HP calculator museum - www.hpmuseum.org). It describes the system memory organization of the HP-85. On page 6-17 the manual explains how to access other ROMs via the bank-switching hooks. Best regards **vp

OT: Clean steel?

by foo＠siconic.com

There are two rooms in the ACCRC building that are filled with huge old (useless) refrigeration systems. Tons of steel. We'd like to get the rooms cleared out so we can use them. We've gotten quotes in the past but all of them will end up costing us to remove the equipment since the rooms are enclosed and one of them is down a ladder with a narrow door. Everything will need to be cut up and removed piece-meal. There is also some very large equipment on the roof that will need a crane to remove. A while back we had a brief discussion about "clean steel". "Clean steel" is supposedly steel that was smelted before the first atomic bomb tests, and therefore contains no radiation. Apparently, air since the first atomic bomb test is now filled with background radiation, and because so much air is used in the smelting process, a lot of the radiation gets into modern steel making it unsuitable for some applications (such as medical test equipment where radioactive isotopes are used as part of the operation). I was thinking that because this building is so old (from the 1930s) that a lot of the steel in those rooms is "clean". I called a scrapper yesterday who has been in the business for 30+ years and is a Harvard graduate, and he said he has never, ever heard of "clean steel". So what gives? Is there a government website somewhere that defines "clean steel"? I'm hoping that the steel is actually worth enough to make it a wash to have it removed. As it stands, the quote I have so far is that we have $25/ton worth of steel and $30/ton to salvage it.

Question about Sharp PC4500 and IBM basic

by kenziem＠sympatico.ca

Can anyone here shed some more light on the sharp PC4500, the IBM basic question? ---------- Forwarded Message ---------- Thank you for your reply. I have a Sharp laptop PC4500 that still works. I don't have a manual for it, and am curious about the unit. There are two expansion slots inside the unit. I was wondering if I can use a mouse with it, but there aren't any ports for a mouse. It has two parallel port connectors only on the outside of the unit. Also, I am looking for an IBM unit with the BASIC code in the ROM. I have a game written in BASIC dating from about 1984 that won't work with GWBASIC. I am curious whether it actually works on an actual IBM (i.e. not clone) unit.

Naming of Systems

by jpl15＠panix.com

I was default sysop of a pair of Sydis voice-phone-data Unix systems back when I was a product manager at a Large Non-Bell California Phone Company. I called 'em Godzilla and Rodan. Not uncommon to get a phone call : "Hey, I think Godzilla just puked.." Earlier, (speaking of Molecular Computers) we sold two of them to a company who did insurance back-office processing. Their resident Geeks named them Pokey and Gumby, and when a user logged into the system, an ASCII-art graphic of the relevant character was displayed on the splash-screen. None of the above machines were made from Pre-Bomb Steel, BTW. Cheers John

OT: RE: Clean steel?

Googling doesn't turn up many hits, but I found two (both related to ships): www.liddiard.demon.co.uk/photoix/brittany/kleber.htm and www.hazegray.org/faq/smn7.htm Given so few hits, maybe is is an urban legend. Then again, some applications might require steel without the slight radiation that blast-furnace smelting might add. The mixing in of contaminated scrap is a different (and very real) issue from air-blast introduced low-level radioactivity.

My understanding of this: "Unclean" steel is not radioactive because of the A-bomb tests (although we are all being exposed to roughly 3 times "natural" background radiation because of those tests. There have been several very expensive mistakes in which highly radioactive contaminants got mixed in with scrap metal going to smelters. Some of these were not detected until toys and table legs made from the scrap were being shipped to consumers. About 40% of our steel comes from recycled scrap. This scrap always seems to pick up some radioactive contamination. The 60% of steel made from virgin ore is "clean". Your 1930's scrap is still scrap -- not virgin ore.

ASR33 linefeed problems...

by jos.mar＠bluewin.ch

After a whole day of finetuning my ASR linefeed pawl stops, I still cannot get it to produce a reliable linefeed. Most of the time I get nothing ,or a half line, sometimes it feeds at each character. Is there any secret to this mechanism ? The ASR manual is not a great help, as it does not mention anything besides the pawls'and their stops. Jos Dreesen

What Is This Connector?

by mhscc＠canada.com

Priority Interrupt chain. Should go from 16FDC OUT to TU-ART IN. Note that the pins on the 4/16/64FDC are the opposite of all other cards, so the cable connects to the same side pin on both boards (away from the edge of the card). The extra wire is in case you have another board requiring connection to the interrupt chain, e.g. a PRI printer interface; if all you have is the TU-ART, just leave it dangling: __+ +_____________ 16FDC | | __+ +_____________TU-ART | | If you have a WDI type hard disk controller with a connector, do NOT connect to it; they have a separate interrupt chain. Good luck; nice to see someone actually bringing a Cromemco back to life. Which model System 2 BTW? Sounds like a CS-2, dual TM100 floppies, full width 21 slot backplane, no internal HD? So, what other cards were in there?

Exxon Qyx Typewriter thingy

by cb＠mythtech.net

So what is an Exxon Qyx good for? Other than as a typewriter? I just found one in my garage (I swear if I dig a bit further, I will find the Ark of the Covenant in there). I found the manuals and software, but I can't yet get to them (really REALLY big pile of gondola shelves are in the way, and I have to move a fridge to get the shelves out... <sigh>). I'm trying to decide if I should haul this out for my garage sale this weekend, or hang on to it. The fact that it is a typewriter with a floppy drive is interesting enough in its own right that I might keep it... but that pack rat mentality is what got everything so burried in the first place (something I am sure just about everyone here is familiar with). Is this just an old word processor, or can you do something more interesting with it? -chris <http://www.mythtech.net>

Hi, I have a Heathkit H-8 of which I know nothing about. I am curious to play with this machine a bit but really I don't know where to start. I believe all I have for the H-8 is the computer - the part with the keypad & led display & a bunch of cables. What can I do with this? How can I test to see if it even works? Any ideas where I could go to find more information about it? Thanks all! Chris Lamrock

OT: Clean steel? more info

by mmcfadden＠cmh.edu

More info for Sellam http://www.geocities.com/darrenmilford/scuttle.html Bayern as raised in 1933. She fetched a scrap value of ?110,000 nearly half of which was profit. The salvage operations on the various ships started in the early 1920's with most of the ships having been raised by the late 1930's. Since then fragments of ships have been raised and since Hiroshima they remain an important source of quality radioactive free metals necessary for certain types of sensitive scientific instruments http://users.accesscomm.ca/shipwreck/index7.htm Radioactivity in the atmosphere has increased over time with the continual testing of atomic bombs of all types. Steel makers need vast amounts of air to make steel so it would follow that steel made nowadays contains certain amounts of radioactivity. Prior to dropping the first A bomb in 1945, steel was radioactive free, and the only source of this 'clean' steel left lies in pre 1945 wrecks that lie on the seabed. Mike

OT: Clean steel? additional ramblings

by mmcfadden＠cmh.edu

Sellam Ismail was asking about "clean steel", here is some of what I know/remember from one of the applications that require it. The trace amounts of radioactive "stuff" in the new steel can swamp out the radioactive particle counters on some experiments. There was an experiment at the University of Missouri to look at the muscle/fat percentages in humans and in cows. There was an especially built building made from "old battleship steel" that enclosed the radioactive particle counter. The "experimental subject" was given trace amounts of radioactive potassium which would be incorporated into their muscle. The entire subject was then placed in a whole body detector to determine the percentage of the body mass that was muscle versus fat. I heard that they had gotten the steel from an old sunken ship. may be entirely myth Thanks Mike

RICM's ZS-1

by pat＠purdueriots.com

Just wandering around the web last night, and I was wondering 'what happened' to RICM's Astronautics ZS-1 ... has it yet been powered up, booted and put through its paces? While I was at Astronautics with Merle, (and everyone else), it looked like a fine machine that would be fun to play around with once it got up and running, and, well, I was just curious if it's been set up and successfully ran any software since it was moved.

Wang 2200 web site and emulator announcement

by frustum＠pacbell.net

Hello one and all. For the past three or four years, I've actively been looking for a first generation Wang 2200 computer. I actually have two now, mostly working. Over the past couple of months I acquired/developed all the technical information I needed to write an emulator. The emulator is far from complete, but it is quite usable. Besides the emulator, I've overhauled my Wang web site and added a lot more content. Now that the ball is rolling, I hope to maintain it more actively. The web site: http://www.thebattles.net/wang/wang.html The emulator: http://www.thebattles.net/wang/emu.html The emulator runs on win32 platforms right now, but I wrote it using a GUI/system abstraction toolkit, wxWindows, so it should be pretty portable to unix/linux/mac at least. If you have no nostalgia for the 2200, why is it interesting anyway? The first generation came out in 1973. Because it was designed before microprocessors were available, it is a microcoded TTL box. In many ways, it can be compared pretty fairly to home computers that came five years later. Because it predates Microsoft, it has a rich and quirky BASIC dialect. Unfortunately, I don't have any Wang BASIC documents online yet, but I do have a quick comparison of Wang BASIC vs early Microsoft BASIC. ----- Jim Battle == frustum(a)pacbell.net

Vintage Scopes

by mhscc＠canada.com

In the August 1968 issue of the "Tektronix Service Scope" there is an article comparing the 512 to the new 323 (the first 'scope manufactured by Sony/Tektronix), and although the article doesn't specifically say so, it does sound like the 512 was the first Tek scope, introduced in May 1949. In another issue an article on power supply troubleshooting does state (in bold print at that) that power transformers are warranted for the life of the instrument (mind you, I guess if the transformer goes, the instrument's pretty dead :). I'll gladly photocopy the relevant page if anybody wants to try to get a free replacement :). Also, further to Toth & Tony's discussion, according to Tek the most common problem when the fuse blows immediately is a shorted diode in the bridge. mike ------------Original Message------------ Message: 43 Date: Fri, 11 Oct 2002 16:39:23 -0700 (PDT) From: "Fred Cisin (XenoSoft)" <cisin(a)xenosoft.com> To: cctalk(a)classiccmp.org Subject: Re: Vintage Scopes Reply-To: cctalk(a)classiccmp.org On Fri, 11 Oct 2002, Philip Pemberton wrote: > Fred Cisin (XenoSoft) wrote: > > Did Tek have any models before the 512? > Not sure.

I thought the Transporter card was an Apple II NIC. But in looking at those pics, I don't see anyway to connect cables. I've never personally seen or used one, so I don't know what kind of cable was used, or where on the card you would look (or if it was even ON the card... might have been a 2nd card that contained the interface for all I know). There is a little bit of info in Google that seems to support my memory of it being a NIC... but nothing that helps explain how to connect it (does seem to indicate that it was a custom network of some sort) -chris <http://www.mythtech.net>

As it stands, the quote I have so far is that we have > $25/ton worth of steel and $30/ton to salvage it. I wouldn't get your hopes up. I know that some of the WW1 German Fleet scuttled in Scapa Flow has been cut up to obtain clean steel -- I've been there and seen the remains -- and I found a reference in the sci.military.naval FAQ to the salvage of German U-boats, but as far as I know, most of that sort of steel is/was wanted for large objects like some of the devices used in research labs like CERN. I found another reference about Fermilab seeking radiologically clean steel some time ago, but not much else. The FAQ points out that the U-boat salvage rights haven't been exercised (and Scapa Flow hasn't been emptied either) so perhaps the demand is too small. The steel can't be resmelted, and possibly not welded either, so if it's to be used, I guess it would have to be of suitable size/thickness to be mechanically cut and formed. Oh, and don't cut it with a torch if you want to sell it as "clean"! -- Pete Peter Turnbull Network Manager University of York

OT: RE: Clean steel?

Clean steel?

by kapteynr＠cboe.com

My understanding of this: "Unclean" steel is not radioactive because of the A-bomb tests (although we are all being exposed to roughly 3 times "natural" background radiation because of those tests. There have been several very expensive mistakes in which highly radioactive contaminants got mixed in with scrap metal going to smelters. Some of these were not detected until toys and table legs made from the scrap were being shipped to consumers. About 40% of our steel comes from recycled scrap. This scrap always seems to pick up some radioactive contamination. The 60% of steel made from virgin ore is "clean". Your 1930's scrap is still scrap -- not virgin ore. The EPA has a new program to address this problem: http://www.epa.gov/radiation/cleanmetals/ -Rob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]On Behalf Of Sellam Ismail Sent: Thursday, October 17, 2002 10:51 AM To: Classic Computers Mailing List Subject: OT: Clean steel? There are two rooms in the ACCRC building that are filled with huge old (useless) refrigeration systems. Tons of steel. We'd like to get the rooms cleared out so we can use them. We've gotten quotes in the past but all of them will end up costing us to remove the equipment since the rooms are enclosed and one of them is down a ladder with a narrow door. Everything will need to be cut up and removed piece-meal. There is also some very large equipment on the roof that will need a crane to remove. A while back we had a brief discussion about "clean steel". "Clean steel" is supposedly steel that was smelted before the first atomic bomb tests, and therefore contains no radiation. Apparently, air since the first atomic bomb test is now filled with background radiation, and because so much air is used in the smelting process, a lot of the radiation gets into modern steel making it unsuitable for some applications (such as medical test equipment where radioactive isotopes are used as part of the operation). I was thinking that because this building is so old (from the 1930s) that a lot of the steel in those rooms is "clean". I called a scrapper yesterday who has been in the business for 30+ years and is a Harvard graduate, and he said he has never, ever heard of "clean steel". So what gives? Is there a government website somewhere that defines "clean steel"? I'm hoping that the steel is actually worth enough to make it a wash to have it removed. As it stands, the quote I have so far is that we have $25/ton worth of steel and $30/ton to salvage it.

Even electronics is not changing that fast, but if your computer is more than a year old, you are no longer"state of the art".

Reading HP series 80 ROMs

Selling old(er) computers in NJ

by cb＠mythtech.net

I'm having a garage sale this weekend in Northern NJ. I will be selling off most all of my 486 and earlier systems. Now I know this isn't of too much interest to people here... BUT, I will also have available the 4 IBM System 23's that I have yet to unload (not do to lack of interest, but due to lack of my ability right now to ship). As well I will probably have some other odds and ends of older machines and equipment. (ATs, and similar, dot matrix printers, a few laser printers,... I have to see what all I have). I may also have some older Macs (all 68k, most 030 or lower), I have to see what I have that I don't currently have a use for, and can bear to part with (I might have enough Mac Pluses and SEs to unload a few, if I can bring myself to doing so). I'm not expecting to get much for the PCs (if anything, really I am putting them on the lawn to see what I get before they are stripped down and thrown out), but I would like to get something for things like the IBM System 23's. There will also be some older A/V equipment, but the only stuff probably of interest here would be some 3/4" Umatic VCRs, the rest is just older amps, tape decks, and TVs, nothing fancy. And of course some of your normal garage sale fodder (I'm bringing some junk over from my house as well). If anyone is in my area and wants to stop by, let me know, I'll give you directions. Its in Ridgewood on Franklin Turnpike on the front lawn of my office (as well as some inside, we have odds and ends of office equipment to unload, and I don't feel like dragging it all outside) -chris <http://www.mythtech.net>

FS or FT - Bare Cromemco System Three

by SecretaryBird＠SoftHome.net

I still have that stripped down Cromemco System Three taking up space here and serving as a shin-bruising hazard in my living room, if anyone in the Pacific Northwest is interested. All it has is a pair of 8 inch floppy drives. I'm open to reasonable offers on this (not sure what would be considered reasonable, truth to tell). Cash is always good, but a trade would be nice as well. I would especially be interested in getting a Commodore PET (the type with the full keyboard instead of the chicklet keyboard, and perhaps a disk drive). The only catch is you would have to come pick it up, as I still do not have a working vehicle to deliver it myself. Any takers? -- Scarletdown

Location of Cromemco System One Revealed

by SecretaryBird＠SoftHome.net

I finally heard back from someone at my unit on the location of that Cromemco System One and Hard Drive. I was told that it went to Re-PC in Seattle (I'm assuming that they didn't mean the one in Tukwila). So hopefully, some collector in this area can find it and score it cheap. I had my shot at it earlier in the month and blew it. Live and learn, I guess. I simply didn't have enough information to go on when deciding what pieces to bring home. There should also be a System Two there as well, since there were two of them, and I only took one. Happy hunting! -- Scarletdown

Hi Patrick I think you might try looking at: http://www.moria.de/~michael/cpmtools/ This stuff is specific to doing cpm stuff but the basics are there.

RK05 Bad Blocks

by jhfinepw4z＠compsys.to

I need some help in reading some RK05 packs. I have 17 RK05 packs and I have been able to read 14 without a problem. Two others have 14 and 5 bad blocks, respectively. The last has 1231 bad blocks. Is there any reasonably easy and simple way to recover the bad blocks. These are all RT-11 distributions prior to V5.03 of RT-11. In particular, the one with 5 bad blocks is a copy of another pack, so I was able to verify that the other 4797 blocks were the same. One down! The ones with 14 blocks and 1231 blocks are for V3.0B of RT-11, but they do seem to be a bit different. The 14 bad blocks are all in 5 OBJ files (for FORTRAN IV) an I may be able to find a copy elsewhere. The 1231 bad blocks seem almost hopeless unless I can find the same distribution and verify that the rest are OK. Obviously there is no point in spending any money since eventually someone will find a set of files for V3.0B of RT-11. Any ideas. I have tried to read each bad block a number of times - one at a time, but no success. I only have until Friday when I will be giving the RK05 drive and the borrowed RKV11D controller to Ethan Dicks.

Questions about a HP Apollo 735/125

by 520055239069-0001＠t-online.de

Hi folks, I just 'won' an old HP Apollo 700 Series, Model 735/125. Unfortunately, I don't have ANY information about it - searching HP's website took me to the service manual, so I know a little bit more about it now. By searching the web, I've learned that I can use a standard PC-VGA monitor with the apollo, by soldering (or buying, :-( ) a special cable. But, a few questions remain: - Anyone has a PIN-layout for the monitor cable? I know that I have to solder red to red VGA, red ground to red ground, and so on, but I don't know the pinout of the VGA connector... Maybe anyone did this before, and can tell me the correct PIN-to-PIN assignments?! - Can I use a standard PC keyboard with the Apollo? It just has a so-called "HPIL"-connector on the back, and I don't have such a keyboard... - What about a mouse? Unfortunately, I just got the machine, and nothing else... - My Apollo doesn't have a standard LAN-connector, just an AUI... But, I saw it has a EISA slot, and the manual told me that EISA is fully compliat to ISA (didn't know this before...). So, can I just equip the Apollo with one of my old ISA Novell/ Eagle-cards? There's an EISA card in the slot, but this seems to be a Token Ring (it's called a "Ring" card) Sorry if my questions are a little bit stupid, but I don't know anything about the machine - just got it from dumpster without any additional informatins, and thought it would be nice to use it. Thanks for your help, I'm glad that there is a mailing list dealing with this systems - thought I've just got > 10kg of old iron, when I start searching the web, :-) keep on hackin', Harald (bofh(a)dh9dat.de)
