vintage computers and lead poisoning?

by vax3900＠yahoo.com

I started to worry about lead paint problem when buying an old house. I bought a lead test kit and tested the paint chips from the windows and fould them to be positive. Then I tested some computer boards, and the result was postive too. Have you ever found white powders near solder on your vintage board? They are most likely lead dioxide. When you power up your vintage computers, some lead dust will be blown to the air and inhaled by your kids... Well, the last sentence is my pure imagination. Has anybody done any research on this issue? To be safe, I am going to throw most of my boards to attic, which are lying on the floor and accessible to my two year old daughter. vax, 3900 __________________________________ Do you Yahoo!?

Cheetah Cub board

by melamy＠earthlink.net

okay, 16 - 256kx1 chips will not give you 2meg... it is only 0.5meg. If the docs you have say 256kx4 then that is the chip you need and the ones on the ISA board are not the right ones. the 256Kx4 DYNAMIC ram chips that you would need were usually used in VGA cards for display memory. best regards, Steve Thatcher -----Original Message----- From: Bill Sudbrink <wh.sudbrink(a)verizon.net> Sent: Jun 9, 2004 8:22 PM To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk(a)classiccmp.org> Subject: RE: Cheetah Cub board > Back to the DRAM nomenclature, the 1 bit vs 1 byte > explanation helps a lot.

Apple LaserWriter questions

by cb＠mythtech.net

>1. Are all LaserWriters 100% pure PostScript printers, speaking nothing >but PS? I know the very original one was, but I'm not sure about whatever >happened later and whatever they make now. No, some models spoke postscript, some spoke quickdraw. Many spoke postscript and other languages (like Diablo, ESC-P, PCL). In fact the original Laserwriter speaks both Postscript and Diablo 630. Apple has a listing of the printers they made, and what languages they spoke. <http://www.info.apple.com/support/applespec.legacy/laser.html> >2. Were there any LaserWriters made with duplex printing capability? If >so, what's the earliest duplex LaserWriter? Yes, and I'm not sure what the earliest one was (I'm also not sure which models supported duplex. Probably the Pro series and the 12/600, 16/600, 8500 series... I know at least the 12/640 rates a duplex page speed, but I believe others besides it also had a duplex option) >3. The original LaserWriter had a serial port. But given the assault on >serial ports coming from all directions, I don't expect the current ones >to have one, or do they? When was the last LaserWriter made with a serial >port? Was there ever a LaserWriter new enough to support duplex printing >but old enough to have a serial port? Actually, most of them up thru the end have serial. The problem is, the serial port doubles as the localtalk port, and it may or may not have been configurable for connection to a PC. As far as TRUE serial (RS-232/422 in the form of a DB25 or DE9), I think the Pro 810 may have been the last to carry that AND talk postscript. I don't know for sure if there is a duplex option for it or not. Later printers may very well also support PC serial via the Localtalk connector (which IIRC is really a RS422 with additional smarts to handle the localtalk protocol) >4. Are LaserWriter serial ports standard EIA-232 DB25 or something Apple >proprietary? If the latter, what kind of adapter would I need to make? Ones that had true serial were standard 232 and/or 422 ports in a DB25 package (there may also have been DE9 connectors, I don't remember for sure). So no adaptor should be needed. For those that handled serial via the mini din 8 connector's localtalk port, you would just need a mini-din 8 to D connector of your choice. Those should be 422 ports... but I can't say for sure that all of them were usable as regular serial. Some may have been localtalk only (and others may have done serial but weren't configurable, so you had to be able to know what it expected to have) Hope some of that is helpful. -chris <http://www.mythtech.net>

Simulators & AppleII copy protected disks ?

by dave04a＠dunfield.com

Hi Guys, I have a friend who has recently retired an Apple IIe in favor of running a simulator. He was able to use ADT and a serial card to transfer most of his disk images over to the PC for use with the simulation, however certain copy-protected games could not be transferred. Does anyone know if there is software available to transfer Apple II disk images on a raw-binary basis (ie: not necessarily well formed sectors), and if so, are there any simulators which can make use of such images? I know this would be fairly complex, as the Apple could do half tracks etc., and timing can be critical to many Apple copy protection schemes. These factors would also have to be delt with somehow - is there anything available which can do this?

DOS application in WinXP

by cb＠mythtech.net

>> Its a medical scheduling application called Perfect Care. > >presumably not related to the "Perfect Software" office suite >of 20 years ago Er, I don't know. http://www.sticomputer.com/ I did just realize their NY Metro office is in Oakland, which is only a short drive for me (10-15 minutes depending on traffic). And I will actually be in Oakland Thursday morning anyway. Maybe I'll just stop in to their office and see if I can have a talk with someone. Although I know when I called the NY Metro office earlier, they redirected me to an 800 number for support, so there may be no one available in Oakland to help me. If I can at least get out of them what fails under XP, I may be able to find a work around. -chris <http://www.mythtech.net>

DOS application in WinXP

by cb＠mythtech.net

>WHAT "application"? It really DOES matter. >"old"? "legacy"? Its a medical scheduling application called Perfect Care. >WHO told you? the author of the program?? Uncle Charlie?? The support guys at the company that made the software. Their exact statement was "we've had major problems getting it to run in DOS under XP". When asked if per chance this was unique to XP, the answer was no, it was a problem with the entire NT line's DOS ability. Their recommended solution? Upgrade to their new Windows based product. That's more or less what is going to happen, but not for another few months (the upgrade is going to a different product, but regardless it will be upgraded, so I need a solution that will run for 4-6 months) >Have YOU tried it? No, but I plan to. But the location is 3 hours away from me, so it isn't something I'm going to drive to give a whirl. It will wait until I am at the location doing the rest of the upgrades. It may be a simple work around, or it may be very complex, I won't know more info until I get there next week. >Sorry to seem harsh, but "been told it won't run" is >quite a bit different from "it won't run". Agreed... but I've been "told" it won't run, and I need to make it run, so I want to arrive at the site armed with options on how to get it to run. >The DOS box in NT (which XP is one of) is just fine >for running "old legacy DOS application"s (PROGRAMS). >BUT,... >NT will NOT permit certain kinds of hardware access, >such as writing disk sectors, "for security reasons". >Therefore, XenoCopy can not run in any version of NT >(NT3,NT4,Win2K,XP). All this I knew. It may be doing some kind of hardware access, I don't know. >If the reason that the "old legacy DOS application" won't >run is because it needs to do something that has been >blocked "for security reasons" (such as writing disk sectors), >then it won't run any better with VPC. Won't it? VPC makes the software think it is running on its own computer. So I would think the software could write to "disk sectors" inside VPC. >From there VPC would take care of altering that into whatever method XP wishes to be used. >So, it DOES run in a Windoze DOS box. There are few things that >will run in a Win95 DOS box that won't run in an XP DOS box, >other than "security risks" Correct, they are currently doing it inside Win95. But like mentioned above, the software developers say it doesn't work inside the NT structure. So they may do something that is restricted (they may also just need a very tweaked PIF and don't bother telling anyone that in an effort to get them to upgrade to a newer version... I really can't say). >What kind of partition does the system have? >Does the "old legacy DOS application" need access to the hard disk? >(ones that REALLY are "old" would not) Don't know and don't know. I have not yet stepped foot on site, and the salesman that did originally spec'd out using a Terminal Emulator to access the legacy system. When I questioned why we had to purchase a new program to access something they are currently doing in Windows (ie: why not just run whatever program they are running now to access it), that is when I was put on the hunt to find the answer. After talking to the site myself, it now appears the salesman was incorrect and it is in fact running a DOS application. BUT, I haven't been there myself yet, so maybe it will turn out to just be some terminal front end. The people on the site don't really know themselves, all they could do is tell me what they do to make it run, and from that I get the impression it is a DOS application (that and talking to the developers, they said it is a DOS app). >1) Boot from floppy with DOS 6.2x. If it DOES need the hard disk, >then make a small FAT16 partition for it to use. > >2) install a dual boot of XP and Win98, and make the drive, >or a partition of it, FAT32. No can do. The app needs to be run side by side with other XP/2000 based apps (the new app that is dictating this hardware/OS upgrade requires either XP or 2k). So I can't do a dual boot as it will prohibit both the legacy and the new app from running at the same time (I can do a VPC type solution since that will run in a window inside XP... but VPC's pricing will probably be an issue for something that I need 5 copies for only a few months) -chris <http://www.mythtech.net>

I'd like to add this here. Fault finding is a cycle: 1. Gather evidence 2. Make hypothesis consistent with the evidence 3. Create test to verify hypothesis 4. Repeat from 1 if that test didn't work and add this new result as new evidence. Number 4 may include replacing a part but usually not unless you are really sure that you've exhausted all the angles. The first rule of intelligent tinkering is, of course, "save all the pieces". The second rule is "don't fix it if it ain't broken". The second rule applies to step 4 as far as doing random replacements. Swapping boards is not all that bad if you are sure you have the right board from repeated steps 1 to 4. When working on old computers, expect to spend time repairing that board as well. Just my thoughts. Dwight > >Yes, this is a rant of mine.

sorry for email delays

by jwest＠classiccmp.org

Sorry to all those who are waiting on emails from me. My mailbox has hit 3000 emails and I just can't make myself go through it all yet, so I'm pretty much only responding to 'emergency' emails. I do plan on making it to VCF east, as long as several other people are planning to be there with certain gear. Was hoping to bring up a bunch of HP cabinets and 7906 drives and 13037 controllers and a 21mx or two. I know I promised the 7906 drives would be refurbed, but I"m not sure I'll get to that in time. The 13037's have been refurbed though. Hopefully I'll be bringing a big load of stuff back and some DEC rack sidepanels! woohoo! Anyways, my apologies to all who are patiently waiting for me to respond. I'll wade through it all sometime fairly soon. Jay

HP 7908 woes

by david_comley＠yahoo.com

My HP 7908 (kindly donated last year by Steven Hirsch) failed this weekend. Investigation reveals that it has blown the 10A fuse in the +12V section of the power supply and when I replaced the fuse it blew again - but stayed up long enough for me to see that the on-board diagnostics do at least begin to run and that the disk itself begins to spin up. Rather than continue to stuff fuses in it I need to identify the root cause of the failure. Recognizing that there could be 1000 reasons why that 12V line is being overtaxed, has anyone encountered a similar issue ? Clutching at straws at this point, but any pointers would be helpful. The service manual that I have does not give any specific guidance on how to deal with this. What's irritating about this is that I had only powered it up to boot an HP64000 to copy some disks. Failing that, does anyone have a comparable CS/80 unit they might be willing to part with ? Or parts from another 7908 ? Thanks, Dave __________________________________ Do you Yahoo!? Friends. Fun.

Well, that won't work for me since I don't use pee seas. (This is ClassisCmp, remember, people use Classic computers here.) But I've read the manual and see that it speaks PostScript and that there are serial and Ethernet options available, while the base unit only has the damn parallel interface. Does yours have either of the serial or Ethernet options? Also the manual is conspicously silent about whether or not it supports duplex printing, so I suspect that it doesn't. Does it? If it doesn't, I'm unlikely to be interested in it, as in that case I would rather buy an LN06R (DEClaser 2250) or LN08R (DEClaser 3250) from a DEC dealer, both of which are PostScript printers with duplex capability and with EIA-232 serial interfaces in addition to the damn pee sea parallel.

Hi Walter and ClassicCmp I just checked Tom's web page and he has the 6502 tape dump there. It is for the KIM so it may need a little fiddling for some other computer. The code at 0100h is the terminal interface. Also, down load the manuals he has there. As I recall these explain how to match your console I/O to his TB. The tape form is similar to Intel hex. The first byte is the number of bytes of data. Next is the 16 bit address. The bytes follow. At the end of the line is a 16 bit checksum. I don't think this matches one of the more standard dump types. If you absolutely need it in Intel Hex, I can send you what I converted from the tape dumps.

DOS application in WinXP

by cb＠mythtech.net

I have an old legacy DOS application that I need to run on new Win XP hardware for the next few months. The problem is, I've been told it won't run under XP's DOS Shell. I'm curious what others have used as solutions to run non NT kernel friendly DOS applications in such an environment. I'm thinking about something like Virtual PC to run a regular DOS 6.2.2 install inside it, but I have no idea if that will actually work. Plus I need to do this on up to 5 machines and buying 5 copies of VPC at the new Microsoft pricing may break the bank (Connectix used to have an OS free version for something like $50... MS now charges $130 for the base price). It looks like VMWare is going to be the same problem with pricing. So does anyone have any other recommended solutions? I'd like this to be as transparent to the users as possible (they currently run the software in a DOS session under Win95, so the closest I can come to that functionality, the better). -chris <http://www.mythtech.net>

DOS application in WinXP

by cb＠mythtech.net

>Find out why it's not working? [Tony's standard rant here, but replace >'hardware' with 'software' ;-)] I tried that. The support department at the developing company was vague, and I got the impression deliberately so. They want to sell their upgrade, not help someone run an outdated version for longer. All they were really willing to share was "XP like the rest of the NT line, isn't really running DOS. Its a kind of DOS emulator and it isn't fully compatible". Yeah, I knew that already, thanks for being helpful. So I really don't know for sure what happens when it tries to run. I will know better when I am on site and can try it myself, but I have a very limited amount of time that I can be on site, and a lot of work to accomplish, so I don't want to go in without some ideas of solutions. I'd rather be prepared then blind. -chris <http://www.mythtech.net>

CRT pinout

by mouse＠Rodents.Montreal.QC.CA

Does anyone know where I can find the pinout for a 3RP1 CRT? I have the CRT and I have most of the important numbers (V/in deflection, final anode voltage, that sort of thing) but I do not have the pinout. I went a-googling, but all I found was a few places that had the silly things for sale. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

DOS application in WinXP

Archive Cartridge Tape Drive 5540C

by d_cymbal＠hotmail.com

Hi all, Anybody know how to access the above running under either DOS or Linux? It has a 5.25" floppy connector on it. I don't have any drivers for it (do I need them?), just a QS.EXE (QuicStream?) archive DOS app which pukes with a divide overflow error during its "Initializing tape drives" phase. Knoppix doesn't even see it during HW detection. Any config pointers? Thanks.

Saw on Ebay: PDP-11/03 backplane

by jdaviscctalk＠soupwizard.com

It's got about a day to go, no bids, starting at $25. I think the 11/03 models are rarer than the later ones so I thought I'd mention it here. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=4135473360… Also has other PDP-11 stuff for sale on Ebay. Btw, I don't know the seller - they listed "vax" in a series of keywords in the ad text, which is how I found it. After reading the recent "VMS vs BSD on VAX" I'm inpired to drag out the vaxstation 4000/90 chassis I have and see if it works (now that I found a serial console cable to test it with), so I was browsing around looking for parts. For the record, if I can get it running, mine will run {Open|Net}BSD. Jeff

Wouldn't that really be a "Flat Monitor" then? The screen may be flat, but so is the screen to a number of other CRT based monitors.

Flat Screen CRT is just that, a CRT with a flat screen. -chris <http://www.mythtech.net>

8" hard sectored floppies

by melamy＠earthlink.net

just to keep terminology correct... the 8" inch came as single or double density - high density entered the marketplace with the introduction of the IBM AT in 1985 that had 5 1/4" high density disk drives. Maybe internationally things were referred to as low and high density, but not to my recollection in the States or in any drive datasheets I have seen. best regards, Steve Thatcher

Looking for Pittman's Tiny Basic

by dwight.elvey＠amd.com

Hi Bob I told you to be patient. I found the stuff over the weekend. Email me directly so that I can send the stuff to you that won't overflow your inbox. I have what looks like an original tape dump, the same code done in Intel HEX and a disassembly of the code. It has a small chunk of code to the console I/O for a KIM but I'm sure one can reconfigure it to work under most any environment. The disassembly only has the address table at the end done as DB's. His code did an address interpreter, similar to how Forth traditionally did things. I'd ment to replace these with address pointers but I've been to lazy. If you send this to Tom, make sure that he gets the credit right this time. It is "Dwight Elvey" ( the second time I've sent it ).

Prerelease Mac Portable?

by cb＠mythtech.net

>My Portable has a weird interface connected to the Conner, though. I think >it's a 40-pin variety. Humm... ok, then maybe it isn't a simple swap. I don't have a portable, so I have to go off the PDF tech guide I have. It doesn't indicate anything special about the drive, so I made what must be a wrong assumption that it was the standard SCSI drive Apple used in everything else of that era. The only picture of the drive in the PDF doesn't show enough detail to know what the connector is like. And Seagate doesn't seem to admit the CP-3045 (taken from the pic on ebay) exists. I did however locate a page on lowendmac.com that shows how to build a 50 pin to 34 pin converter cable to replace the Portable's drive with a more standard 50 pin SCSI drive. It was listed under the pages for the Mac Portable. -chris <http://www.mythtech.net>

IBM 5150 and Full-height 5.25 Floppy Drives

Hi Bob, I would be interested in this - I Am located in Ottawa, and am planning to be in Toronto later this month or early next month - where exactly are you located? And I have a pair of TM100-2 drives sitting on the shelf! The Horizon is a nice machine - used to have one years ago, and have not been able to find another... I have a NorthStar disk controller installed in my Altair, which runs NorthStar DOS as well as my own DMF system. There's a simulator for this machine on my "museum" page: http://www.dunfield.com/~ddunfield/museum/index.html This will let you boot up NorthStar DOS on your PC! Also have most of the NorthStar manuals and a lot of other reference info. scanned and posted there, which may be of use to you.

Prerelease Mac Portable?

by cb＠mythtech.net

>Maybe not -- it's apparently not bootable. Dead disk, it seems. >From the description, it sounds like it is just another dead Apple SCSI drive. I have gone thru stacks of these 40 and 80 MB drives from Apple (all Conner I believe, just like the one pictured). They seem to have motor failures and stop spinning. But the Portable uses a standard 3.5" SCSI drive, so it is fairly trivial to swap the drive. Granted it lessens the "value" if it carries a different drive, but since I've already been outbid, I'll stick with the idea that it will exceed my price threshold before it sells. :-) -chris <http://www.mythtech.net>

new hamfest finds

by rigdonj＠cfl.rr.com

I went to a little hamfest today. Brought back another SWTPC Function Generator and two OLD or homemade (or both?) vacuum tubes. These things are weird! Other finds include the main unit for a Pace MBT desoldering station (no handpiece or tips :-(. Also a HP 12C calculator and NOS military lead acid battery from 1953. It's about 2" square and about 5" tall and is made of clear plastic so everything is readily visible. It's never had acid put into it and has never been used. It's sort of cute and it makes an interesting show and tell piece. Pictures later. Joe

Xerox workstation for sale

by yoda＠isr.ist.utl.pt

Hello everyone. Several years ago I got a Xerox workstation from a junkyard. I believe the model is a Daybreak. At that time I got it partially booting, using some homebrew interfacing hardware. At the meantime I got married, and I have to get rid of the thing (lack of space and wife's interest ;). However, I don't want it teared apart for recycling. I want it preserved. Therefore, I'm puting it to sale! I live in Lisbon, Portugal (EU). I have some photos online at the following URL: http://www.isr.ist.utl.pt/library/gallery/Xeroxworkstation I also have three peripherals: two tape streamers and one 5 1/4 floppy drive. Since it has no keyboard, mouse or monitor, I built interfaces to connect it to a VGA monitor, and to a PC. I can include the stuff I did with the machine.

486 dies terrible death

by vcf＠siconic.com

My voicemail PC died a pretty terrible death this morning. I was still groggy from a late night of hackering and sitting at my computer (my back is to the voicemail system) and all of a sudden this loud popping begins. At first a wave of terror washed over me as my not quite totally functioning brain was trying to determine just what the hell was going on. At first I didn't want to look but I turned around in time to see some serious arcing going on inside the exposed PC (the case is off). It went on for a good 4-5 seconds (start to finish). It was probably the power supply but I can't tell for sure until I do a post-mortem (right now I'm getting my voicemail back up). Luckily it didn't take out any hardware. The hard drive is fine and as far as I can tell so far so are the voice boards. That was some crazy shit. The power supply fan went bad on it a while ago (over a year, surely longer) and I never bothered replacing it because I always use just whatever hardware I have laying about whenever something goes bad on the box, and those damn power supply fans go out all the time and it's a pain to have to replace them. Anyway, I wonder if it was some critical thermal failure of some sort. The P/S was hot but not abnormally so (abnormal in this case would be scorching but usual temperature is very hot to the touch but not burning).

Proposal: Oldware database

by mtapley＠swri.edu

All, I was thinking today about old software (okay, I was playing Master of Orion 1 :-) ) and realized that there may be a service opportunity we have. I don't know if such exists already, please point me there if it does. What I'm thinking of is a central site to point out old software or software for old systems that have been placed in public domain or otherwise made available for nominal charges by their original manufacturers. I'd like to see something like a database containing: Name of package Brief description (maybe two paragraphs) Rating (something like a one-to-five-mice rating, or maybe with valves?) Platform/OS it runs on (database should be sorted on this field) Where to get it Company that made it. Current owner of that company, (includes web-link) Current main product line of that company Person/group responsible for making it available Current business of that person (includes web-link) A couple of examples I know a little about: Lighthouse Design Ltd Office Suite Office Suite, consists of mail, spreadsheet, text, presentation packages vvvv (four tubes out of 5) NeXTStep 3.x http://www.peanuts.org/peanuts/NEXTSTEP/commercial Lighthouse Design Sun workstations/servers ??? ??? OPENVMS 7.3 Operating system, utilities, development tools vvvv VAX, Alpha hardware http://www.montagar.com/hobbyist/mount.html DEC HP printers :-) ???? ???? But even here, I don't really know the right people to credit. This seems like a good way to return a bit of good karma to the folks that support old hardware and software, as well as a valuable resource for those of us trying to do vintage computing on a budget. I guess I have not thought far enough into how to limit the database from becoming enormous. I'd say some necessary criteria are; 1) package runs on a "classic" (that is > 10 years old) platform 2) package was at one time sold in the normal software marketplace (i.e. not shareware/freeware/etc since inception) 3) package can now be downloaded or ordered from somewhere for free/cost-of-media/similarly low cost. Comments or suggestions? Some questions I have: a) should there be a separate category for software for classic systems which is still being sold and supported (a la the older Ambrosia shareware games for Mac, like Escape Velocity, or Create! for NeXTSTep 3.3)? b) should there be an "archive pointer" section that points to existing archives of shareware, such as http://www.peanuts.org/ for NeXT stuff? (I think this would be *far* preferable to trying to catalog every single shareware package on every archive....) I don't have any webhosting skills or abilities, so I can't set this up, but if I can help, let me know. -- - Mark 210-522-6025, page 888-733-0967

Computer flooring/flooding/water in computer rooms

by classiccmp.org＠irrelevant.fsnet.co.uk

I was at a customers some years back.. Old building, but it had been totally gutted and all new insides. There was a small cupboard to the side of the computer room (actually more of an office, where the MVME based Motorola unix box and one of the patch panels lived) inside of which was the main fusebox for the floor. 415V three phase splitting off to (our normal) separate 240V circuits.. Anyway, I was sat at a desk with my back to the cupboard, server in front and to my left, and suddenly heard running water... turned around, and the wall behind me was swimming... opened the cupboard and it was pouring down the cables and across the fusebox.. The power went off shortly afterwards.. luckily it missed the server, which was on a UPS, and we did an orderly shutdown. It was Air Conditioning again .... For some reason known only to themselves, the AirCon plant for the floor was situated in the loft (Attic) directly above the computer room. It had a drip tray under it, which wasn't secured, nor drained properly. When it got full, it tilted, and dispensed it's entire load of water onto the floor, and hence us below! It did it again a few weeks later, too.... Not as much fun as the time we got a phonecall from a customer saying "My computer just blew up". We chuckled and said we'd come have a look, expecting a fuse blown or something. Arrived and found a PC clone with all the blanking plates, buttons, and the front of the floppy drive on the floor in front of it, the blanking plates on the expansion slots all bowed outwards, and a nasty smell in the air. We decided the remove the machine from site before opening it ... When we did, found it was a 486 machine where the battery backed CMOS ram was (had been) baked up by an external battery plugged into the board. This had been stuck to the back panel of the box. It had exploded! Possibly connected to the board backwards? The force of the explosion had been enough to fling bits of battery and the plastic box it was encased in /through/ the ribbon cables in the machine, as well as the aforementioned ejection of all loose fittings on the case. Battery acid everywhere, too, eating through tracks on everything. The hard disc survived long enough to get the data off it, but the rest of the machine was pretty much destroyed. And this poor girl had had it under her desk by her feet when it had gone bang! Poor thing must have had the shock of her life! Rob.

Cromemco memory

by pete＠dunnington.u-net.com

Oops, I deleted the original so can't reply directly to it :-( I hope someone has better info than me, because although I think I have a 16KZ-K for my Cromemco, the only manuals I can find are for Godbout, Irvine, Integrand, Tuscan, and a few other memory boards -- none of which I have! All I can find is the entry in the 1978 Cromemco Microcomputer Systems catalogue, which says that it offers expandability to 512K bytes with bank select, has fully-transparent dynamic refresh, operates at 4MHz with no wait states, and costs $495 (fully assembled, tested, and burned in, as the 16KZ-W, is $595). "With bank select each memory board may reside in one or more of the 8 possible memory banks. An 8-position DIP switch on the board is used to select each of the banks in which the board resides. "The active bank or banks of memory are selected under software control. Output port 40H is dedicated to this function. Each of the 8 bits of data of output port 40H are used to turn on or off the corresponding bank of memory. A "1" in the corresponding bit position will turn on the memory bank. A "0" will turn it off. All circuitry required to detect the output of 40H is included on the memory card itself. "Bank select provides a convenient method by which to expand system memory space beyond 64K. Bank select also permits the implementation of time-sharing systems with a minimum of software overhead - up to 8 users can use the system simultaneously with each confined to his own bank of memory." This implies the card can be multiply decoded (to appear more than once). I imagine if you want it to appear from 0000H to 0FFFFH, you turn on the switch in position 1, and turn off the rest (unless you want it to appear elsewhere as well). Similarly to appear from 10000H to 1FFFFH, switch position 2. Although, since it's easier to provide a pullup resistor than a pulldown on TTL, likely "switch on" grounds the line and means a "0". Try it and see! -- Pete Peter Turnbull Network Manager University of York

Do you know any more about it? Maybe. If so it must have been identified before the leads were added, because the Intel Data Catalogue 1976 lists both 2704 and 2708 on the same page, and the only difference is pin 22.

Interestingly, the 1976 book doesn't list anything bigger than a 2708. So a 2708 obviously wasn't a half-bad 2716 (at least, Intel ones weren't). The 1979 Data Catalogue lists the 2704 only as a footnote to the 2708 description, and the 2716 appears only as a single-rail version.

There is a difference between single and double density that is related to the position of the index hole.

In fact, I punch a new index window in some of my double density 8 inch floppies and I've been using them, with no troubles, as single density. The 5-1/4 disk are a different story.

When they first started making 2716's, TI was biting into their 2708 market with the 2758's. Intel fought back with their version of the 2508. These were early half bad failures from the 2716 line. They even had a H/L pin to select which half to use. When they first started, they sold for quite a bit less than the 2716's ( about $30 ea ). Over time, the 2716's pricing went down to around $4 someplace. I got a kick out of seeing one of their price list showing the 2508's still being sold for $32 ea. While I suspect that originally the half bad parts made sense but at the premium price they got for these, I suspect that they later just took fully tested 2716's and relabeled them. I wonder how many purchasing agents realized that the 2716's worked just as well. Dwight

Cromemco 64KZ and other S-100 board information needed

I have a Cromemco 64KZ-II memory board but no manual. If anyone has a manual in PDF format, that would be ideal, but in the absence of that, I'd settle for a short description of how the board is organized and what the 3 dip switches and two LEDs do. I am also looking for the following manuals if anyone has these in PDF formats: IMSAI VIO, MIO and SIO2-2 Processor Technology VDM-1 and 3P+S Industrial Microsystems 8K static memory board Seals 8K Static Ram I have over 100 manuals in PDF format, and have made significant contributions to the S-100 manual library at: http://www.hartetechnologies.com/manuals/ Direct E-Mail responses would be appreciated.

Classic PDP-8 wire wrap bits

by aek＠spies.com

I was thinking about the poor guy in Finland that was going to have to rewire his PDP-7 backplane tonight, and did some digging for bit/sleeve part numbers. Amazingly, you can still buy the right stuff from Cooper Tools. They have a really neat pdf catalog http://www.cooperhandtools.com/catalog/pdffiles/electcat_00/Brands/WireWrap… >From a 1967 DEC Logic Handbook, you need a gardner-denver 26263 bit and 18840 sleeve for #24 wire and 504221 bit and 500350 sleeve for #30 wire. The #24 unwrapping tool is 500130 These may also work for 1401 connectors, which are quite similar to the H800 DEC single sided module blocks with rectangular shaped pins.

8" hard sectored floppies

by d_cymbal＠hotmail.com

Are hard sectored 8" floppies of any use to anyone? I've got several boxes of still shrink-wrapped SSSD hard sector disks. I've sold a couple boxes on epay, but action on them was lower than I'd imagined. Some folks who resell alot of 8" floppies told me "good luck" because hard sectored just don't sell. I've seen new soft sectored disks advertised online for fairly hefty prices (don't know if they are selling at that price or not). What systems made use of these? Any that I might own or want to own some day that it'd be worth me holding on to these if I can't sell them for a price worth it to drive to the post office and ship them?

The original IBM hard-sectored 8" floppies had 8 sectors, and I don't think 3M ever made those :-) -- Pete Peter Turnbull Network Manager University of York

Found Today - Sony SMC-2000, etc.

by marvin＠rain.org

Something I've wanted for quite a while is a Sony SMC-2000 computer with the LDP-2000 laserdisc player. Today I finally got it! This unit had been used by a local school and they needed to get rid of it. It came with some laserdiscs and ... four service manuals for both the computer and laserdisc player! Apparently this runs MS-DOS 2.11 and I don't think that came with it. But unless that is a special OEM version of MS-DOS, it won't be a problem. Also included were 8 laserdiscs including three volumes of Dream Machine and two volumes of Space Archive discs. They also had several shrinkwrapped packages of IBM DOS 3.30, and I put one of them on VCM. Also listed on VCM was a copy of the IBM Guide to Operations for the Personal Computer XT, and Volume 1 of the Hardware Maintenance and Service for the Personal Computer XT (these are duplicates of what I already have.) BTW, the money received for these will go back to the school computer lab. They had quite a bit of stuff that will either be sold or sent to that great storage location in the sky. It looked like there were quite a few ISA sound cards, network hubs (10 Mb/sec), etc.

What's the best way to cut a PB book apart for scanning?

by aek＠spies.com

I found my Millenium MicroSystem Analyzer manual while searching for the manual for the Brikon 723 FD tester. I thought I'd scan it but it's bound into a paper back book. What's the best way to cut it apart so that I can scan it? My scanner has a feeder and it's th only way to scan something. -- If the glue has dried out, just break the binding and peel the pages apart. clean the hardened glue off the edge before feeding through the scanner. Alternatively, go to a print shop and have them cut the binding with a paper shear, making sure the spine of the book is flat.

Wanted: M9312 ROMs (data i/o help needed)

by rigdonj＠cfl.rr.com

(1) I have a 29A manual but there's no device codes in it. The codes are in the manual for the particular plugin that you're using so you'll have to tell us which one you're using. (2) I think I have a 29B manual but I'll have to look for it. (3) I didn't think the 29x programmers could program Bipolar PROMs but I'd be happy for someone to prove me wrong! (4) FYI Just because the PROMs are 82S131, Am27S13, 63S241, 74S571, etc don't think that they're all the same. They may be interchangeable in a read-only operataion but they're programmed very differently. You MUST have the proper settings and adapaters for the PROM that you're using.
