Very wide but not descript. Thoughts on that? It might have been an upgraded 512K Mac; I believe there was a Plus upgrade for those. The printer might have been a Wide Carriage Imagewriter. There's a story that goes with that item: "... As Cary and I walked past Steve's office, we heard him yelling at the printer guys, reminding them that every Wide Carriage ImageWriter built with the hard-to-get microcontroller would likely cost the company a Mac sale. "If you build even one of those Wide ImageWriters?", and then he told them about a certain part of their anatomy that would be "cut off" if that happened. The printer guys looked like they would rather be anywhere else than right where they were. Before too much longer, Apple did ship the Wide Carriage ImageWriter, the microcontroller shortage cleared up, and I always felt privileged to have experienced so much about the Mac division on my first day....."

Apple Computer Collecting

by SUPRDAVE＠aol.com

I'd say any of the technical books from Addison-Wesley are worth keeping. Ive got the BASIC programming with ProDOS and it's pretty detailed. There were so many neat options back in the day. For example, I've got a ][+ with a special 80column card designed for it that could run a patched version of Appleworks. It also had a replacement encoder board to do lowercase and had macro capability. Of course, the apple SCSI card is worth looking for. I've got one and tried to connect a drive and no luck. Will have to try again. The //c+ is pretty neat. I eventually got one, but they are not easy to find. If you can find a working Apple /// or ///+ get it. I lucked out and got a complete functional one with hard drive and original disks. And of course, the LCD display for the //c. >>What in the Apple line of computers, etc. is worth keeping, i.e. >>hardware, software, documentation, and books? Besides the Apple I, are >>there any other "holy grail" type of items?

Help with a Power Supply

by jhfinexgs2＠compsys.to

I could use some help with what seems to be a BAD power supply. For the past month, I started to experience more and more frequent crashes of the system. About 2 weeks ago, I figured that it seemed to be the power supply and I started to use an external power supply for the 3 hard disk drives. That solved the problem and a few days ago, I replaced the internal power supply so that now the 3 hard drives are back on the new internal power supply with the rest of the system (and it is now very quiet again since the external power supply had a noisy fan!). Since I am not Tony Duell, I will just be tossing the old power supply. However, before that, I would like to know if there is a simple way to test the old power supply to determine if that was the actual problem? Please don't mention anything that requires me to open up the old power supply. I only have an old analog volt meter and could put a few light bulbs into a test circuit, but that is about the limit! It really is not that important, but it sure would be interesting to know if that was the specific problem. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

Matrix 3U CPU card?

by rigdonj＠cfl.rr.com

I found several of these a few days ago but I can't find anything about them or the company that made them on the net. They're 3U type cards with 68000-10 CPUs and are marked MATRIX MS-CPU-02C. I found one mention of a computer company called Matrix in an old copy of a VME news letter and they said that the URL for Matrix is www.matrix.com but now that URL belongs to a company that supplies hair care products. Does anyone know any more about Matrix or these cards? Joe

HP9826 Question - Basic 5.12 and such

by keith＠saracom.com

Hello all, I have a question or 2 to ask on the HP9826. I am now the proud owner of the labs old system. Now I have several issues to resolve. The first is the reason I have and the lab does not. The display is out of focus and not too bright. I have tried to adjust using the pots inside labeled focus brightness. It helped alittle but not much. Any ideas? Also its no fun without an OS. Now we have BASIC Ver 5.12 at the lab. Unfortunately its on 3 1/2 inch diskettes and the HP9826 has a 5 1/4 diskette drive. Hence short of using a mallet that won't help. So is there a method of using a PC to make 5 1/4s for it since I do have the 3 1/2s? Thanks Max

Mattel intellivision

by witchy＠binarydinosaurs.co.uk

Hi folks, Anyone have any troubleshooting expertise on these things? Got one of my spares out for sale and typically the bloody thing is pretty dead. I say *pretty* dead 'cos I get the cart intro screen on power up, but with the computer module attached I get nothing. I've left it powered up for 15 minutes in case it's a warm up problem but that makes matters worse :) According to the service manual I have to replace either the RAM or CPU in that order, but since spares for those will come from working intellivisions I don't want to do that! Also, off the top of my head I can't think of any other videogames that use the General Instruments GI1610 CPU, assuming it's that that's croaked. The RAM is a GI-specific chip too. Spares, anyone?

Help with early Mac serial numbers

by jrkeys＠concentric.net

I pulled one of my early 128k Mac's from storage for part of a Apple display I'm doing on the 17th and was trying to find out the breakdown of the serial number. The number on the unit is F40220FM0001 and I'm guessing that the two F's are just there for show and that 40220 is the serial number and M0001 is the model number? Is this correct?

Heathkit et-1000

by DFoster＠aol.com

Dear Kevin: I've been browsing the web for a schematic for the Heathkit ET-1000 digital trainer and I saw your posting. The unit has been fully repaired, but I'm still worried about future repairs. By any chance or design, do you have a schematic you could fax or email me? It would even be helpful (and perhaps sufficient) if you could identify the DIP chip on the Main Board (not the Power Supply board) that is labeled "2206CP 8271". Might it be a function generator chip? NTE and other sources do not list what this chip is or what it does. Anyway, if you still have data on the ET-1000 help would be very much appreciated! Thanks, Dave (DFoster(a)aol.com)

AIX

by ceby2＠csc.com

All -- < RANT_MODE=1 > Sorry, I never could pass up an internecine fued of the UNIXes.... I'd like to go on the record. I love AIX. And there are a couple of bullet points we've missed in our description of it. The most important is its underlying object repository. This may have been the seed of the AIX vs. AS/400 thread. AIX invented the central system registry long before Microsoft. That's the engine behind its package and device management. It's the underlying engine most of the standard admin commands ultimately converse with. Very un-UNIX - and thank you to the IBM _wunderkinder_ for that. UNIX is a wonderful thing, but why must we live in a timewarp where anything not envisioned in the 1980s isn't "real UNIX". Let's move on shall we? Linux is a good example. It's based on a complete rewrite of Minix, itself a complete rewrite of AT&T System V. By all means, let's preserve the vintage, and don't throw the baby out with the bath water. But why should the UNIX community turn Luddite? IBM as we've all said, did a rewrite of the kernel. Rather than porting System V and glomming on some Berkely additions, IBM re-engineered the code >from scratch. In the upcoming version, they are doing it again to accomodate even more robust enterprise configurations with sub-CPU LPARs and mainframe like accounting/management facilities on a rapidly advancing 64-bit CPU design. It's my own assessment they are moving AIX to the top of the tree for big iron, and moving the zOS hardware toward commodity Linux VMing. It's a move that follows the market's application development trend for enterprise systems. Thee development community writes more for big Unix, so this is perfectly sensible. Just to keep this post from being too out of thread, I might just mention my 10 year old 990 and 390 RS/6000s are still wonderful machines to work on now. I use the 390 as a graphic station (if you could believe it). It scans and GIMPs with the best of them. Only compression routines make it slow down. The I/O's faster than the laptop I'm writing this post on. Okay, < RANT_MODE=0 > Colin

working magnetic drum stores?

by julesrichardsonuk＠yahoo.co.uk

Just out of curiousity, does anyone still have a working drum storage device? wondering if any working examples have survived... I have a half-assed plan to try and find one from somewhere at some point. We have a Sperry unit that's way beyond repair, and don't have anything other than the drum assembly itself anyway (the bearings still seem good though so I might see if it can be coaxed into spinning) - but a working demonstration would be great hooked up to one of the 1960's machines. I gather that telphone exchanges used to use them here in the UK so maybe there are still a few lurking in private hands as they must have been reasonably common at one point. The flipside of course being that they're pretty bulky devices in themselves, and with the low reliability they've maybe all gone to scrap years ago (unlike other peripherals of the area which survived). cheers Jules

I have that one too, it's my first VARM, one of Tim Shoppa's early gifts to Quasijarus Project. The early VARMs, the EK-VAXAR-RM ones, are lovely: 100% pure ASCII, except for boldface section headers the book is line printer output. From the appearance seems to be very close to the DEC internal VAX spec, DEC STD 032 (though not having a copy of the latter it's an educated guess). But then they stopped issuing VARMs in that format, and published it as a book (with ISBN and all, rather than an EK part #). The book version of VARM had two editions: 1st ed. in 1987 by Tim Leonard (listed as the keeper of the DEC internal VAX spec in an appendix to another highly secretive DEC internal spec I have) and 2nd ed. in 1991 by Richard Brunner (wonder what happened to Tim...). I have acquired both of these books recently. Not having a copy of the genuine article (the DEC internal STD 032 spec) I have to live with the published versions instead, so I was trying to acquire as many of them as possible to complete my mental picture of the complete architecture spec and its variations. (I'm designing a new VAX CPU chip, so I have to have a very solid picture of the spec requirements and options and their evolution.) Would anyone perchance have a copy of the real VAX spec, DEC STD 032 aka EL-00032-00 aka A-DS-EL00032-00-0? > I don't recall seeing an rtVAX mentioned in it, and the index > does not list anything beginning with rt-. Yeah, of course the 1982-05-20 VARM predates it by a few years. Brian Chase <vaxzilla(a)jarai.org> wrote: > The 2nd Ed VARM has a section on rtVAX memory management, 11.2.3 on pgs > 422-424.

Table 8-2 on pp. 331-332 lists the SID code assignments, and 16 decimal is listed as "rt/uVAX (chip 78R32)". Knowing that 78032 is the MicroVAX II chip, used in KA630, KA410 (MV/VS2000), and a bunch of other less-known systems (see the SYS_TYPE codes the same table lists for SID 08), it's pretty obvious that the rtVAX 1000 listed by the table as being based on this 78R32 is the KA620. Since the MMU is internal to the CPU chip, the difference between KA630 and KA620 is in the silicon (78032 vs. 78R32) rather than board-level. MS

I also have a papertape reader assembly but no punch (you'd need an ASR baseplate to make it into an ASR-33). Make me an offer. I'm in West Plains, MO 65775 so you can figure shipping. -Charles

Hi Although, one may have some success by shipping in a cardboard box only ( mine was trashed ), it should be bolted to at least a piece of plywood. If this is put into a box, proper strain relief should be done where plywood edge meets the box. This is so that the plywood doesn't just poke through the box. These units are too heavy to be in a cardboard box alone. Dwight

debugging a tu58? blank tapes or bad read channel?

by brad＠heeltoe.com

Does anyone have any suggestions about debugging a TU58? This is a dual TU58 from a vax 730. The symptom is that when I try to boot from it the tape rewinds a bunch of times and then reads off the end of the tape. I removed it and poked all around with a scope and the schematics. The motor control is fine as well as the tachometer. The read channel shows no activity, even when I put a tape in and move the tape. The micro seems happy. I connected it to "tu58ctl" and I can talk to it and send/receive commands. But when I try to position the tape I get a "motor stopped" error. I'm begining to wonder if the 3 TU58 carts I have have been bulk erased. I have no "known goods" and I've never read these tapes. I made the assumption they were good but that might be a mistake. (wish I had those mythical proms which can write carts :-) I put a scope on the signal from the read heads and I see nothing when the tape spins by. I find that very odd. I would think I'd see pulses even if the blocks where all zeros... So nothing makes me think the tapes have been bulk erased. Is there any way I can test the read channel without having a good tape? (I assume not, but I know very little about tape drives, perhaps there is some 'technique'). I know the tapes are useless if they have be bulk erased - but will the symptom be no read channel activity? (I assume so). blah. if I've wasted all this time on bulk erased tapes %$#%@#@!#$ -brad

Looking for spec sheet for MK6207N/MK5017BB clock chip

by dickset＠amanda.spole.gov

I've found an old RadioShack package with an MK5017BB Clock/Calendar chip. Unfortunately, the datasheet which was once stapled to the back of the card is missing. Google doesn't have much on it. One interesting reference is at www.datamath.org/Mostek_IC.htm where the part number is listed in a series of calculator chips (it lists the MK5017 as having been in the Corvus 305 calculator, with square root, 1/x and a clock/calendar). I also found this picture on the die itself... http://www.mindspring.com/~mary.hall/mosteklives/photos/mostek_mickey.jpg But no specs. Does anyone have info on this thing?

finding old RAM

by ghldbrd＠ccp.com

SIMMS are the new stuff -- lets talk old, like: 1 meg X 1 bit DRAM in a 20 pin DIP package. I bet most of that has ended up on the landfill by now. I need a large quantity to populate Amiga RAM boards. Gary Hildebrand St. Joseph, MO

Comparing existence of massive number of files

Matrix 3U CPU card?

by mmcfadden＠cmh.edu

Joe R. was asking about Matrix cards We used to have a VME based x-ray film scanner that was a Matrix product, it was a prototype. If I remember correctly I think Matrix was based in California and made film cameras and scanners for industrial applications. Our initial unit had a VME controller with a micro PDP-11 as the network interface. I think I have the micro PDP-11 somewhere in my garage. Looks like Agfa purchased them. Mike

Comparing existence of massive number of files

by RCini＠congressfinancial.com

Patrick: Funny you should mention Windiff. After reading the responses today I was going to use Windiff to compare the directory printouts produced on both machines and see if there's a difference in the output. But thinking about it, Windiff has the ability to directly compare directories. If I point it at the top "parent" on each machine I should be able to see differences right away. I guess then the final test would be comparing the MD5's on each directory to ensure file integrity. Any good MD5 utilities for Windows that will handle large file sets? I downloaded two today but one is a file-by file MD5 and the other doesn't recurse down the directory tree...it only does the current directory.

Time to Purge! -- I think it's all spoken for.

by nerdware＠ctgonline.org

I've gotten a pile of emails this morning, so after I sort through who wants what and who asked first, I think it's all gone as of this moment. As soon as I figure it out, or if I come up with more stuff, I'll post up. If you've sent me an email -- I'll get to it in a little bit. Thanks!

Shipping a Teletype

by cb＠mythtech.net

>Any estimates on what would be a "reasonable" estimate for shipping a >Teletype (with base, two cartons] Origination is Long Island, Destination is >not known except it will be within the "lower 48" states. I shipped one a while back. I broke it down into two parts, the teletype and the base. I packed each in their own box. I got boxes that were a good bit larger than the part to be packed, and IIRC, then lined the boxes with formed FedEx boxes (the free ones you get from them) to act as stiffeners. Then lined the interior of the now "double box" assembly with bubble wrap. Then heavily wrapped the item in layers of bubble wrap. Then placed it into the box, filled the voids, put on the top layer of lining boxes, then taped it shut. I think the total cost was something like $40 or $45 per box to go from NJ to St Louis (it was probably 2 years ago, but I seem to recall it was something in that range... I think the boxes were about 65 lbs each packed). I'd assume they arrived in good condition as I didn't hear any complaints >from the person I sent them to. You can ask Jay to be sure, he's the one that got it. >Also any recommendations on a carrier? I used FedEx Ground, simply because I had a FedEx account, and they were willing to do it cheaper then UPS. >Finally any "sepcial packing techniques [specifically any internal >assemblies that need to be secured]? Um... I can't help you there, I honestly hadn't thought about that issue until you asked it here. Now I am worried that I caused the thing to be trashed in shipping because I failed to bolt something in place. (Probably not, or I'm sure Jay would have complained) -chris <http://www.mythtech.net>

The first TWO hits that I got are for Dial Electronics. They have the part listed but don't say what it is, who made it or how much they want for it. The next two hits are for HKinventory and they give the same lack of information. Then USBid, Doom, and others. NONE of them give any information about the part at all. Thre are pages and pages of the same kind of useless hits. That's why I'm dumping Google! Joe >Peter Wallace >Mesa Electronics > >

Time to purge!

by nerdware＠ctgonline.org

I'm officially giving up collecting. When I started, I didn't realize the amount of space it would take, and I also didn't realize that there were people out there with 1000 times more stuff, who actually had time to use it.... I've gotten rid of most of it a couple years ago, but it's time to get rid of everything except my original Vic20 and C=64, and my 2 Amigas. Here's what has to go: 2 Apple IIGs cpu's, one 5-1/4" floppy, one 3-1/2" floppy, modem and monitor 3 Apple Disk ]['s Apple ][e Apple ][ Monitor for ][ (monochrome) Macintosh Performa 400 Imagewriter ][ Smith-Corona Daisywheel printer (was used with Kaypro II) Commodore Plus 4 IBM PCjr box of Kaypro software miscellaneous Apple software other crap as I come across it I just want this to go to someone who has time to play with it. You pay shipping -- it's yours. Or, if you're in the Chicago/NW Indiana area, I can arrange for pickup. I want this out of here by the end of next week. If nobody wants it, it will unfortunately go to the recycler. Email me. Thanks.

Matrix 3U CPU card?

by mpokorni2000＠yahoo.com

Matrix might have been a maker of VME CPU boards, but video board maker from Montreal was named Matrox and they are still in existence, web address is: http://www.matrox.com/ . You might want to try VITA's web site: http://www.vita.com/jun96vj/toc.html for some information on Matrix' CPU boards; VITA is VME maker's association and they might have information on legacy products. Additionally, you can try search on Google for all three words: "matrix cpu vme". Regards Miroslav Pokorni

Comparing existence of massive number of files

by rcini＠optonline.net

Hello, all: I just moved most of my collection of on-line data to a new server here at home. I want to verify that all files have been copied and I didn't miss any directories/subdirectories. Basically I did it through a drag-and-drop across the network. What's the best way to do this? The OS is Windows NT (Server) and I'm looking at about 22gb of files of various types -- from music to source code. Any ideas? I still have the original server on standby for this verification before I wipe it clean for sale. Thanks again.
