I suspect that the motherboard for the tape drive is the same as the one in your optical jukebox, but with different ROMs. There is also a DIP switch in the back (for setting HP-IB address and various options) and a bunch of jumpers inside. I have no idea what they are supposed to do. If you want I can take a photo of the motherboard and send it to you. **vp

FA: Collection of Otrona Attache Parts -- Complete System?

by patrick＠vintagecomputermarketplace.com

I collected a number of Otrona parts over the years with the intent of reassembling them into a working system, but that hasn't happened, and I think other interests are going to keep me from ever spending the time it needs. I think almost everything you need to build a basic working system is here. I have the following items available, up at auction on the Vintage Computer Marketplace... http://marketplace.vintage.org/bid.cfm?ad=727 All items are completely and totally untested. Links to photos are on the listing at the link above. * Six CPU boards, "pulls"... Most with parts on them, one bare board. The ones with parts all have some parts missing that I think are relatively easy to find: 765 floppy controller chip, Z80 PIO or SOI, or 5027 video controllers, etc. Only one board has a 5027 on it, but I also have a "loose" 5027 that I will include. I have EPROM images for the CPU board EPROMs. * Three floppy drives loose plus two in their chassis components--the special not-quite-half-height drives the Attache used; * GPIB cards in various states of assembly, rework, or disassembly. I believe there is also an 8086 card, but it's stripped of parts. * Case and chassis parts that I believe are enough to build (or reface) a complete unit, include outside cover, two rear bezels (one with PSU attached to it), a front bezel still wrapped in foam, keyboard shell top and bottom halves, handle; * Additional keyboard assembly, dirty, but usable; plus three keyboards without case. * One video/CRT field replacement unit (tube + boards + mounting hardware), plus an extra video board, extra yoke, and another incomplete video assembly. I think I also have a third partial assembly in a box; if I find it, it will be included. * A number of expansion/daughter cards for 25th line, graphics, and high-res graphics; some are loose, but some are mounted to CPU boards (see photos). * CP/M boot disks in unknown condition (images also available from Don Maslin, I believe). * Binder with schematics.

DEC vt100 terminal stuff / parts available

by jwest＠classiccmp.org

I have 2 VT100 terminals plus a vt100 plastic shell that I'm parting out. They are VERY yellowed cases, obviously a smoking environment. Definitely some screen burnin too. On at least one of them the fasteners that hold the top of the case to the bottom of the case are broken. I don't think they are worth much more than the junk heap. They all power up and go into setup mode just fine. They are all true VT100's, not 102's, etc. Some or all of the keyboards are missing some keycaps. I think one keyboard may have all it's keys. In addition, I have a vt102 without the top or bottom case. It is in perfect working order, clean, and no burnin with one major flaw. The metal band around the front of the tube has slipped, meaning two of the L brackets that are held down by that band have slipped back so the monitor is about 1/2 inch forward of where it should be. Thus it won't fit into a plastic case quite right. The band is too tight to push the L brackets back into place, and I'm not comfortable cutting that band and trying to put a new one in place (something about working with a large glass object under pressure scares me a bit). So far my plan is to keep the vt102 chassis as spares, and ditch the 2.1 vt100's. If anyone wants me to scavenge parts (logic board, power supply board, flyback, transformer, keycaps, crt tube, etc.) I would be happy to do that. Total price for each shipment will be shipping cost + 5 bucks (unless you just want a keycap or something)...negotiable. The only stipulation is you must let me know in a day or two, I'm itching to get them out of the house and gone. Jay West --- [This E-mail scanned for viruses by Declude Virus]

DEC 11/23, RL01s,RX01s,VT100,LA120

by beclassic＠att.net

I am just about ready to rid myself of the DEC equipment I have. I'm starting with the classic computer mailing list, but I may part the stuff out on e-bay. I want to preserve the equipment and related manuals, but I'm also not ready to just make a gift. The equipment was purchased in 1979 with updates in maybe 1981. It was used in my business and has only been moved once (Fall, 2001). It is now in my garage which is obviously not air conditioned. Most of the manuals and printed materials are in a storage room a few miles away in "conditioned" air. The computer was used primarily as a BASIC processor, but we also had compiled Dibol applications we developed (actually DBL). I have the mid-height (42") newer-looking cabinet containing the processor and dual RL01's. The dual RX01 unit is stand-alone, desk-top unit with matching exterior. The original basic unit was an 11T03 with an 11/03 processor. After a few years I swapped the processor to an 11/23 (dual size M8186): KDF11-AC with KTF11-AA makes the cpu a KDF11-AA. Also added KEF11-AA FPU to help my number crunching. Current memory is 256K (MSV11-LK). The monitor is a VT100 with an extra board for advanced video, plus a tilt-swivel stand (DEC version). I also have an LA120BA terminal unit with keyboard that I used as the wide-carriage printer. I generally used TSX and at one time had a time-sharing client using a proprietary program through a 1000 baud modem. I believe the latest RT11 I used was v.3B, but v.4 may also be there. I have the usual stuff that went with operating the machine: - printed docs ( box of paper ) for diagnostics, plus microfiche version - original diagnostics on RL01 - original manuals for each item (I think) - some hardware diagrams/schematics, along with installation booklets - 8-10 of the small paperback books of equipment from DEC - 4-5 large blue notebooks from DEC regarding operating system, etc. - maybe 9 RL01 disk packs in total - a few used RX01s - software - RT11, BASIC, Fortran?, TSX?, DBL? - some confusion in this since the distributions came from a third-party developer via RL01, not from DEC on distribution-type media. The CPU and memory seem fine. The bottom RL01 powers up but shows a fault light; the other works fine. Both RX01 drives work. The VT100 works fine. Haven't tried the LA120 lately. I recently hooked a PC as the console and used Kermit to transfer all the data on the RL01s. I have slowly been trying to separate my data from DEC data on the RL01s and do a wipe routine after, thus protecting client data. Maybe I'll only release half of the RL01s. I've infrequently reviewed the digest versions of this mailing list, but this is my first attempt to participate. I am switching from digest so that I can try to be responsive on-line (generally between 7:00 pm and 11:00 pm EST). Are other times more appropriate? I can also answer emails, generally within a half day. I can maybe get some pictures on-line, but most of the participants in this list know what they're dealing with. I'm in central South Carolina. bill bailey

Got the machine far enough apart to spot those and play with them yesterday. Sure enough, that fixed the screen-shift (and it's almost a certainty that I disturbed them when I took out the Elf Armor). FWIW, the plates are perpendicular to the path of the electrons in the CRT and more or less centered on that path near the back end of the CRT. They are circular (umm, annular? I can't see anything but a mm or two at the rim of the circle), and have little tabs at 2 locations 180 degrees apart. There are 2 plates, stacked together. They are "finger tight". I fooled with them while watching the image, but I used an insulated tool, so I didn't fool with them much. A slight twist (maybe 15 degrees) on one of them moved the image right where I wanted it. Thanks, Tony! Still in the to-do list: ordering a new rectifier (thanks, Chris!) against the day my CR5 dies (but it seems OK right now, picture is fine and steady) and borrowing an o-scope to see how much ripple is on the 5V line. And probably saving up for an ESR meter to test the caps around the connector that goes to the digital board, and probably getting a new capacitor or two. And retouching J4. After the picture adjust, coincidentally, machine ran fine for several hours yesterday (all the time I could spend on it). Love that BrainStorm! -- - Mark 210-522-6025, page 888-733-0967

7 track tape terminal

by aw288＠osfn.org

I have an extra Mohawk Data Services 7 track (!) tape terminal available. Basically, it is a tape drive with a keyboard - oh the weird stuff they used to do back then! Anyway, this is a late 60s (probably) all transistor and core box, about five feet tall and 300 pounds. It takes standard tapes. I don't think the thing is completely working right now, as I can't get it to do much, and a light blinks as in "something wrong!". I have no docs on the thing. I should also say that the keyboard on this thing moved the bar as far as how bad human engineering can get. Anyway, I want to make it go away, so if anyone has stuff to trade (no micros, please - (cruddy) big stuff or docs are good) or has a little cash (were not talking much here folks - scrap value is probably only $100), we can deal. I can deliver to VCFeast or anywhere near NY/NJ/CT/RI. I could ship it as well, as I do have a sort of crate thing. Let me know! Please, I need the room! William Donzelli aw288(a)osfn.org

Hyperions

by brianmahoney＠look.ca

Over the years, I have been pretty successful in acquiring Hyperions. Actually the bulk of my collection is Hyperions. A recent letter to the group made me pause and think about the future of my Hyperions. I won't sell them but I would love to have them with someone who can sort out the hardware and the manuals and make the information available to those who are interested. At this point I have too much on my plate to do this myself. Trades will be considered but not outright sales. I've contacted a couple of the Canadian museums with an offer of this equipment but haven't been honored with a reply. Soooo, Canada is good but if they have to go to the states, so be it. No shipping though, only pick-up in Scarborough. Points for anyone who is interested in these units : 1. Are they of interest to someone who could pick them up in Toronto (Scarborough actually, 20 minutes from the CN tower.)? I won't ship them. 2. My original Hyperion, which I purchased and am keeping, does not boot so the others may be in the same condition and I already know that at least one of the storage towers has had some trace problems, if that's what you call them. There are about 6 complete units, one for parts and two storage towers that are about two by three feet and very heavy (maybe 50 pounds or more.) 3. I'd like to keep one set of manuals but there are doubles and triples of just about everything plus boxes of software and records from their original site which was a Canadian tech college. 4. There would have to be some agreement that this stuff wouldn't be sold as I was given all of it under the condition that I wouldn't sell it. If you have a museum and are interested in this stuff, that would be absolutely prime. 5. All of the material has to be kept together. I'm not going to piece it out. It has value both monetary and historically and I would love if it could be in a bricks and mortar museum somewhere. That's about it. Volume is probably a stretch mini-van full or a bit more. If nothing happens with this, I will obviously keep it all and hope my kids will be interested in it in about ten years. If you have some ideas, let me know at : antique101(a)hotmail.com I may add to this if I've forgotten anything important. bm

The RD53s are toast, but is the controller O.K.? I'll lend you an RD54 with some version of VMS on it if you want to try to boot that way. Either way, I have a MVII with some RD54s on it (maxtor 2190s I believe) and maybe a loaner rqdx3. and we can talk about the back door also. BTW, I am coming up on my vacation, so I'll get back to you about the other qbus stuff I have, if you still want an LSI-11 flavor machine... Joe Heck And no, I haven't forgotten Curt, Steve and the many others who have asked about the "stuff" I am getting rid of. During the month of June when I am off from work, I'll get back to all the emails I saved about my equipment.

Heathkit H8 emulators

Things are jumping over at www.sebhc.org , with more than 70 members committed to the preservation of Heathkit 8-bit computers - come take a look. Several of us have tried unsuccessfully to get in touch with either Dave Shaw or Dave Wallace, both of whom created websites featuring H8 emulation, one Mac-based, the other Windows-based. While email addresses are available, no-one has had a recent response from either Dave. Can anyone on classiccmp provide some help - 1) working email addresses for Dave Shaw or Dave Wallace, or possibly for reviewers of their emulators, including Larry Bledsoe, Steve Novosad, Charles Horn, Neal Granroth, Stanley Webb, or Bob Myers; 2) did anyone download the emulator source or support files from Dave Shaw's defunct website?

Find: HP 97

by mouse＠Rodents.Montreal.QC.CA

I just picked up an HP 97 at a church rummage sale. It was sold "tel quel" ("as is"), so it was a bit of a gamble, but I figured if it was broken it'd be even more fun 'cause then I would feel no compunction about opening it up and Investigating. The battery pack appears dead (based on a 1kohm/volt voltmeter, it's producing about .1V) and it didn't come with a wall wart. But the battery pack was visibly made up of four cells, so I figured four rechargeable cells is probably about 5V - and the external power connector is marked 5V. So I hooked it up to 5V from a peecee power supply (peecees are good for _something_; they provide me with power supplies :), and it seems to be in full working order. Even the printer works (though the ribbon appears a little enfeebled). All I need to do is find a manual for the thing. Anyone know of one? Google found me a few places _selling_ scanned copies of the manual, but none civilized enough to have it up for fetching. The thing cost me all of five bucks. :) Maybe not quite on a par with an ASR33, but it's also a lot easier for me to find space for. As yet I may be but a dilettante when it comes to old computing gadgets, but *I* think it has a healthy dose of gamish! /~\ 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

Microvax 3100-95 SCSI oddity

by witchy＠binarydinosaurs.co.uk

Folks, Spent a day troubleshooting this one so I'm wondering if any of you have come across this before: 3100-95 with internal SCSI set at ID 7. Give it a boot disk at any free ID and another device (doesn't matter what) at ID 6. At the dead sergeant prompt all the devices are visible, but boot VMS 7.2 and whatever device you have at ID 6 is not seen unless it's the boot disk itself in which case it shows up as DKA600. Is there something hard-coded into VMS for MicroVAX 3100s that always assumes the SCSI controller is at ID 6 no matter what? I know that older 3100s always had the controller at 6 and I don't remember it being changeable.... Most odd :) Cheers! -- Adrian/Witchy Owner & Webmaster, Binary Dinosaurs www.binarydinosaurs.co.uk - possibly the UK's biggest online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

Summagraphics tablet?

by mouse＠Rodents.Montreal.QC.CA

Does anyone know, or know of a reference to, the serial-line protocol spoken by Summagraphics tablet digitizers (specifically, the MM1103)? I have one. After a bit of detective work, I got it to at least somewhat work. I now have it to the point where I can connect it up and turn it on. When I do, I get nothing until one of the buttons on the puck is pressed, at which point it starts generating a stream of samples, continuing for as long as some button is pressed. The format is fairly easy, just %04d,%04d,%1d\n sent with the 0x80 bits set to provide even parity, where the four-digit numbers are the location (based on an 8.5" edge of a piece of paper and some arithmetic, it appears to be 200dpi) and the last indicates what button is pressed. This makes it all at least somewhat usable. But I'd really like to be able to get samples back even when no buttons are pressed, whence my question. The back does include a sticker saying, among other things, "BIT PAD FORMAT", which may or may not mean anything useful. I did go a-googling, but either there's nothing to be found or I didn't guess the right incantation to find it. `Summagraphics MM1103 serial protocol' turns up no hits - though it probably will once this message gets archived and googled :) - and neither did `"bit pad format"'. It _is_ on-topic; there's a sticker on the back with a Date: field containing a handwritten date that is clearly in 1984 (it appears to read "10/17/84"), which contains other text implying it was added by a leasing/service organization.

Need Bernoulli cartrige

by rigdonj＠cfl.rr.com

Hello, I'm working on an old Bering 8020RM HP-IB disk drive that uses a removable disk cartridge. I found that it uses a Bernoulli drive and it uses a 8" cartridge. I THINK the disk is 20Mb but I'm not sure. Does anyone have an old 8" Bernoulli disk that I can try in it? Joe

Slightly off topic: I need to recover some data (about 500MB) from a tape written 8 years ago on an 8mm ExaByte 8200. Ultimately I need it transferred to a hard disk but DAT (DDS or DDS2) or DLT (anything that can be read on a DLT7000) would be an excellent intermediate step. Does anyone in the UK have the ability to do that for me? I can provide the DDS or DLT tape. -- Pete Peter Turnbull Network Manager University of York

DEC Diagnostic Disks (incl long listing)

Are the HELP.TXT files found on a couple of disks fairly detailed or > are they rather terse? They won't help much with individual diagnostics, but they do tell you how to do things in general. > Is an XXDP manual online anywhere? Some time ago (about 11 years) I created a document about how to use XXDP; it's called "Notes for XXDP+ and XXDP V2 Operating Systems" and it's at http://www.dunnington.u-net.com/public/PDP-11/ In fact, IIRC, I put that doc on the web in response to a request from you (Christian) several years ago :-) There are PostScript and (thanks to the kind services of another listmember, Bill King) PDF versions. It's also mirrored on at least one other site which also has some XXDP info. XXDP is an enhanced version of the original XXDP (there's also one we used to refer to as XXDP++, but I'm not sure either name was offical), and V2 is what came out with the later microPDP-11s. V2 is a bit friendlier. The document consists of notes I made in the mid-80s when I was on a DEC maintenance course, plus reformtted stuff from the V2 files. So long as you remember that much of it uses the V2 commands, and replace them with the V1 equivalent, it will be useful. The one thing I never got round to doing -- because I have it on paper,in various forms -- is a list of *exactly* what each diagnostic is. There's a partial (very incomplete) list at http://www.chd.dyndns.org/pdp11/xxdp25.notes.txt See also http://starfish.osfn.org/rcs/pdp-11/xxdp/ Will Kranz also had some stuff -- he was working on how to completely decode an XXDP disk, but his site at earthlink has disapeared. > I checked > bitsavers.org already - just something on DEC/X11 extant.

If nowhere else, it should be at the front of any complete set of XXDP microfiche. > 2.) Pete indicates these are a basic set of XXDP (XXDP++) disks for a > microPDP-11/23. What functionality will they have on my 11/73 (or a 11/53 > if I build one up from a heap of parts on hand)?? Actually I think they are XXDP V2, now that I think about it (I don't have a system with an RX50 on it at the moment, to check). They'll test most of the basic hardware in the machine. Read the document and the list I referred to; it'll let you work out what hardware the tests are for. But to actually use certain of them effectively, you really ought to have the listings of the individual diagnostics. They don't all print nice messages; sometimes you need to know what the "switch settings" are to make them do certain things, sometimes they just halt on error and you can't tell what happened unless you can look up the error address in the listing. For example, for the ZKMA memory test: bit 15 set = halt on error bit 14 set = loop in selected subtest (see bits 0-3) bit 13 set = don't print errors bit 12 set = enable memory management bit 11 set = enable parity testing (default is ignore parity bits) bit 10 set = halt after each sub-test bit 9 set = don't do program relocation (so it can't test all of memory) bit 8 set = test in blocks of 4K, and print the first failing bit in each block bit 7 set = enable "long galloping test" (takes a while :-)) bit 6 set = don't size the memory (normally the diagnostic tries to work out how much memory there is to test) bit 5 set = don't print "END PASS xx" (normally does this every time round the loop) bit 4 set = don't print anything bits 0 to 3 are used to select a single subtest. See bit 14. Machines used to come with paper listings (though I think that practice stopped around the time of microPDP-11s) and some sites had the set on microfiche (one and a half boxes about 15" deep, so it's a LOT of microfiche for the whole set). We've discussed this on the list several times before. Maybe I should dig out the rest of my XXDP paper notes and scan them :-) -- Pete Peter Turnbull Network Manager University of York

cd longevity

How >retro :) > ---snip--- The only real chance is to make sure that the data has redundant storage. Paper burns well. Why is it that many of the classic systems we like have no docs. These docs were on paper. One type of storage is no solution at all. When I look at things like older floppies, the biggest failure I've seen was the higher end floppies with the inner liners. The self sticking adhesive eventually migrated through the liner to the disk surface. Of course wear and tear is an issue for those in constant use but I'm more concerned here with archiving. As you can easily see there is no especially great storage media. Each has its downfalls. Redundancy in media types as well as redundancy in the actual data stored are the only chances we have. As the article points out, there are unforeseen problems with most every single method. Any valid system must allow for this and respond to this in a preplanned procedure. I store my valued information on as many storage types as I can. There are practical limits for me. I try to get others to duplicate what I have ( with limited success ). What if my house burned. What if the roof fails and the rain comes in. What if I die. What if, what if.... We are solidly into the "Lost Information Age". Dwight

HP 85-86 roms

Unfortunately this is not possible, unless you can disassemble the ROM and then reassemble the code with the desired "relocation" address (ORG). This is also the reason why HP-86/87 binary programs are incompatible with HP-83/85 machines and vice versa. A better bet is to try to find a programmable ROM drawer on eBay etc. Check also www.series80.org for other info on HP 85-86. Best Regards **vp

I joined the RT-11 development team in 1978... and got my first office in the mill. At that time we had a lab full of systems where we did our development and testing. Occasionally there were fire alarms and evacuation drills at the mill. It was not unusual to see a bunch of us with our RK05 (or RL01,02) disks which contained the most recent RT sources, out in the parking lot. The first thought many of us had when the alarms went off was to power down the drive and get the disk... then calmly exit the building...:-) Megan Gentry Former RT-11 Developer +--------------------------------+-------------------------------------+ | Megan Gentry, EMT/B, PP-ASEL,ST| email: mbg at world.std.com | | Member of Technical Staff | megan at savaje.com | | SavaJe Technologies, Inc. | (s/ at /@/) | | 100 Apollo Drive | URL: http://world.std.com/~mbg/ | | Chelmsford, MA 01824 | "pdp-11 programmer - some assembler | | (978) 256 6521 (DEC '77-'98) | required." - mbg KB1FCA | +--------------------------------+-------------------------------------+

FS: Franklin Ace 2200 CPU

by stokesp＠earthlink.net

A while ago I retrieved a Franklin Ace 2200 from a neighbour who was throwing it out. Well most of one, anyway. I have the CPU and the joystick. No keyboard, no screen. The computer is clean and while I obviously can't really tell, it appears to boot. I believe it has 128K RAM (8 4164 chips on a riser card and 8 3764s on motherboard). No expansion cards. There was a floppy in each drive; when you power it up it beeps and disks spin and click away for a while like it's loading its DOS. I know next to nothing about this system, and don't want to get into diagnosing anything... Until finding this one I knew them only from cheesy Byte ads when I was 10. I grabbed this one for good obsolete computer karma, so someday when my Atari 800XL craps out I hope there'll be someone who snagged one from a neighbour for a dollar back when neighbours still had those things, and I'll pay him well. Five bucks plus shipping (your choice). It's built like a tank, so the shipping is not going to be free. If you live around Boston MA you can come get it. Respond by direct e-mail: I don't normally read this mailing list, it was suggested to me by another old computer enthusiast. Enjoy and good day, Peter.

I had a machine that ran for a couple of years; never powered off because it was a pain to get the drive to spin again. Well, the inevitable happened, and I had a power cut last August, which outlasted the UPS. This time the usual tricks didn't work, and I ended up taking the drive into the workshop. Even giving it a higher voltage on the 12V supply wouldn't make it start, so with nothing more to lose, off came the top. I discovered I could release the brake by hand, but even so I had to apply 14V (instead of 12V :-)) from a big bench PSU directly to the innards, and flick the disk with my finger to get it to start. However, once started, it would run on 12V, though it wouldn't restart normally if I let it stop. I had to think about how to keep that drive spinning while I took it back to the machine. Don't try this at home ;-) It went something like this: connect a PSU from a PC to the smallest available UPS, and stack the PSU and and the topless drive on the UPS . Start the drive as described above, then whip off the bench power leads and connect the PC PSU before it has a chance to spin down completely. I seem to remember using a paper clip to disable the brake while doing that. Unplug the UPS from the mains and carry the whole lot up to the office, with the drive still spinning. Connect to the computer, cross fingers, and power up the computer. To my surprise and releif, I was able to read almost all of the drive. I only lost a couple of files. Needless to say I replaced the drive after that :-) I've taken the tops off small drives a few times. I don't recommend this, because I may just have been lucky, but as a last resort it's allowed me to rescue the data from a few stuck or damaged drives. Except for the most recent one (I took the wrong screw out and finished the drive off). -- Pete Peter Turnbull Network Manager University of York

Life with PDP-11's.

by mmcfadden＠cmh.edu

In 1977 I started out with an 11/35 with 4 RK05 drives. System was on one pack, programs on another pack, data was stored on 2 packs. Software was hard coded to look for 2 Megs of data files at a time. When we got the RP04 we made it look like 20 RK05's to the application software. In about 1980 our R&D lab had upgraded from a PDP11/35 to a PDP11/70 system with one RP04. We were in a computer room in the middle of a warehouse, when we asked for more AC they said we could have an additional air conditioner. About a week later a sawsall blade came through the wall of the computer room as they cut a hole for a new window air conditioner. The output side was in the general warehouse space! We were a little mad because nobody warned us about the dust flying into the computer room. We shutdown until the AC was installed. It did cool the room down a lot. Only having one RP04 was a problem. Whenever a backup was scheduled I took the system pack and the backup pack in the back of my Toyota to another computer room a mile away so that I could do a standalone backup. Nothing like walking across the parking lot with the system disk in one hand and the backup copy in the other. I was careful not to drop either pack. Later we thought about getting a VAX 11/730 but decide the 11/70 was fast enough. Mike

ICL7660?

My ability to search the web is hampered by poor sat comms right now, so I'd like to ask if anyone knows where to purchase an ICL7660 negative voltage supply chip? My Basicon MC-1N is apparently missing it, but RS-232 comms being as loose as they are, I can still talk to it even though there's no negative comms voltage.

Testing a Dead VT52

by Ashley＠carderweb.com

I acquired a dead VT52 DecScope today and I am going to attempt to revive it. I have a copy of the VT52 maintenance manual. I am also getting a second one that "lights up" in about a week. I am hoping to be able to create at least one functional VT52. Does anyone here have any experience repairing a dead VT52 DecScope? When I apply power, I hear a mild hum coming from the transformer area, but there is nothing on the screen.. no cursor, no raster. I just turned it on this evening and have not followed through the debugging information in the manual. One thing I did notice is that the manual talks about a fuse on the back. There is no fuse on mine, but I do see what appears to be a circuit breaker button on the right side near the on/off switch. Any ideas from experienced folk would be welcome! Thanks, Ashley

Stiction (was: Atari TT030 install media)

by dave04a＠dunfield.com

>never mind - stiction it is... I got the bottom board off the drive and >managed to free up the spindle by hand, it now seems to spin up properly >by itself... I have a little story about Stiction ... this is not "cyber legend", this actually happened, and I was the one who did it! Way back, sometime in the mid to late 80's, when this stuff was not cheap or easy to come by, somebody gave me a dead Lapine "Titan" hard drive - I think it was a 20meg drive. The drive just wouldn't spin up at all. I tried the "shake and bake" technique, rotating it back and forth about the spindle axis during power up etc. - no dice, the drive just would NOT spin up. So, "this is trash --- lets look inside". Popped the top off, and immediately discovered that the platters did not want to turn. On closer inspection, I discovered that the head did not want to budge >from the platter surface, and came to the conclusion that the head was stuck to the platter. Memory is a bit dim on exactly what I did, however during my fooling around the head eventually came lose, and I could spin the platter - there was a discolored spot which had been under the head - it was slightly rough due to a bit of surface corrosion or deposits. I don't recall why, but "just for kicks", I took a fine cloth, polished the spot on the platter (IIRC it was still discolored, but I removed the surface deposits). Blew out the drive with a bit of air, and put the top back on, and installed it in a machine to "see what would happen". Not suprisingly the drive spun up right away. So, I low-level formatted the drive and ran a test --- then I got a suprise --- NO ERRORS! This was interesting "I wonder how long it will last", so I left it running surface scans overnight --- in the morning --- NO ERRORS! So I used it for "non critical" data - months went by and I never got a disk error. Eventually I gave the machine to a company I worked for who used it as a lab/test machine, and when I left the place a few years later, it was still going and to my knowlege had never gotten an error.

I don't have intimate experience with the TT030 (haven't found one yet), but I believe it has the operating system in ROM, just like the ST series, which I do know fairly well. I do know that with my ST machines, the screen just shows "white" unless there is a diskette in the drive. Then the system will come up. The ST (and I believe the TT) uses a FAT format, and can read/write DOS disks - a blank formatted disk works on the ST, so I'm guessing it might work on the TT as well. Failing that, I do know someone locally with a TT030 who might be able to send an install disk image...

Mac keyboard tunnel software

by cb＠mythtech.net

>Do you >think Timbuktu would lag on a GB ethernet setup? I meant to put this on the other email... sorry. I'm not sure where the lag is happening in Timbuktu. What I find isn't so much a delay in things happening, so much as it is a delay in me seeing it. If I click something that should beep, it beeps pretty much right away... however, if there should also be a window pop open, I won't see the window open until a good half second or more later. And I don't notice that the lag is too much worse over a slower connection (dialup and DSL). So it may just be the way Timbuktu deals with sending the screen draws. Also, it seems easy to get ahead of it. If you move the mouse too fast, it won't show you where it has gone, and then it jumps. So you end up moving slower so you can target correctly rather than constantly jumping around the screen hoping to get the right spot. And you have to click slower or it will accept it as a double click or ignore additional clicks. None of it is that far off. Maybe by half a second. But when you are doing long, repetative things, those half seconds add up fast. Since I can't say that I notice a huge difference in the lag when there is a huge difference in bandwidth, then I tend to think the lag may be elsewhere. Either in the remote machine's ability to processes everything, or in Timbuktu's limit of displaying or sending/receiving the data. -chris <http://www.mythtech.net>

Mac keyboard tunnel software

>Is there any reason an ADB KVM can't be used in this setting? Only because I toggle between the two often. I think flipping a switch back and forth will get annoying. I'm not sure that sliding the mouse across the top of the menu bar won't also... but I just have a feeling that will be less annoying (mostly because I currently use two monitors on my one Mac, and already move the mouse between screens all the time, and I don't find it the least bit annoying, so to me, I just think it will be like having an additional screen to work on, that just happens to have the processing happening on another computer). -chris <http://www.mythtech.net>

Mac keyboard tunnel software

by cb＠mythtech.net

>That doesn't mean there's no lag (you say "because"). Try it over a >satellite link, or a slow dialup, sometime. Oh very very true, over a slow connection. I know I used it in the past over a localtalk network, and it worked without lag. Simply because there wasn't enough data being pushed to be an issue. I'm sure over a slower connection that wouldn't hold true. However, because this software does NOT push the screen image of the remote machine back to the primary Mac... you really wouldn't use it over anything other than a LAN. You need to be able to see the monitor physically connected to the remote Mac to use it. All this does is allows you to bypass using a different keyboard and mouse. >Of course, this does mean that the two machines in question are almost >certain to be connected by a low-latency high-enough-bandwidth link.... Exactly. Since the machine is unlikely to be more than a few feet away, you can use Localtalk at the very least, which in my past use, was sufficient bandwidth (I ran it on a 25 MHz 68040 over localtalk connecting to a 100 MHz PPC 603 laptop... now I want to use it on a 400 MHz G3 connecting to a 250 MHz PPC 603e over 10Mbs ethernet... so I'd assume there will be no lag as well... there is only minor lag in Timbuktu which does FAR FAR more) -chris <http://www.mythtech.net>

Mac keyboard tunnel software

by cb＠mythtech.net

>I think we experimented with something like that years back. What we had >was called Timbucktu (spelling?) I probably should have mentioned in my original post that I am attempting to replace Timbuktu. Timbuktu does a fine job, EXCEPT that I find there to be enough of a lag that it gets on my nerves when I use it thru the day. The software I'm looking for was the software equivelent of a KVM switch, without the V. There was no lag, because all that was being done was sending the keyboard and mouse commands to the remote machine. You still viewed the remote machine on its own monitor. -chris <http://www.mythtech.net>

DEC HiNote Ultra Battery Problem

by matthias.bauchinger＠chello.at

Hello Fred van Kempen, I've seen your post quite some time ago about your problem with the "locked" battery of the Dec HiNote Ultra. You wrote that is was kind of "locked" and that DEC came up with a small tool to "revive" it. I now have the same problem with my notebook. It doesn't charge...even in the small LCD-display at the right of the display-chassis the battery-icon is not displayed. But I can not find this small tool which should bring up my battery again. The url (revive.com) seems to be replaced. Could you please help me with a hint or something? That would be very nice. best regards Matthias Bauchinger PS.: Sorry for posting it to several email-adresses...was not sure which one would work. PPS.: Your old post: Ha! DEC noticed a problem with these battery packs "locking up" after extensive periods of no activity, so they came up with a small utility (revive.com) to "revive" the batt pack. It worked, too.. my battery came back to life, and, after a full charge, is as good as were it new.. ! Lappy is not a portable, ultra-light TCP/LAT/Serial/X11 terminal :) (muhaha, with 802.11b WLAN ;-) Cheers, Fred

hp proprietary uP history

by aek＠spies.com

I was wondering how much information is around on the microprocessors HP built in the late 70's/early 80's I found some information on the MC2 in the Osborne processor books from '79, and it appears an MC5 is used as the maint processor in the HP3000 Series 44. Anyone know what processor is used in the HP64000? One note on Usenet claimed it was an Inmos part?

looking for a computer with front panel

by gohai＠gmx.net

Hello, I came across a screening of 'Wargames', with a presentation afterwards about the computers and hacks used in the film ... and I was just blown away by the front panel of the IMSAI :) Do you know of any programmable computer today which has a programmable front panel? Are there maybe some machines for education? Or are there classic computers which have this feature and are less rare (and expensive) than the IMSAI? thanks!

Mac keyboard tunnel software

by cb＠mythtech.net

Once upon a time I had a program for the Mac, older program (System 7 era) that allowed you to "tunnel" your keyboard and mouse to another mac. The way it worked was, you would move the mouse to the top corner of the screen, above the Apple menu, and "push" thru to another screen. It would then move your keyboard and mouse control to another Mac. Basically, it worked as a software KV switch (no M as it required you to have a monitor on the other Mac). I've been unsuccessful in turning up a copy of this program in my archives. Partly hampered by not remembering what it was called. Does anyone remember what this software was, and do they have a copy they can send me? -chris <http://www.mythtech.net>

DTC MicroFile

by brian＠quarterbyte.com

Hi, Does anyone have any recollections or information about the DTC MicroFile? Data Terminals and Communications made it. It's a piece of furniture on wheels, contains a box with a dual 8" floppy drive and appears to be designed to sit in between a terminal and a daisywheel printer -- a primitive word processor? Haven't had a chance to crack the box open yet, and am curious if anyone has any concrete information. Cheers Brian

Tektronix CP-1160/DEC something

by rigdonj＠cfl.rr.com

A couple of months ago I found a DEC computer with a front panel. Then I found a second one a few weeks ago. The panels are painted in two tone blue Tekronix colors. I finally got around to photograghing one of the front panels today. I'm posting a picture of it at <http://www.classiccmp.org/hp/dec-k/cp1160.jpg>. Sorry but I haven't cleaned it up. It's also missing two switch handles. The first one was marked as being a 11/35FC but I don't remember seeing a model number on the 2nd one. Joe

hp proprietary uP history (9825 uP?)

by swtpc6800＠comcast.net

> That's what you'd think but it isn't the case. 9825s in paricular are > nearly indestrucable but I have constant problems with all of the 9845s. In 1979 I did a data-logging project at the Hanford Nuclear Reservation in central Washington. We had 6 or 7 trailers that collected ground water measurement on HP 9825s (using the built in tape drive.) The measurement equipment was connected via HP-IB. The power was from a mobile generator. Every time the air conditioner started the line voltage would dip about 25 volts. This test ran for over a year with out a single failure. I was impressed. In the spring of 1980 the place was thick with grasshoppers. They would get into the equipment it you let them. After Mount St. Helens dumped a foot of ash on the place there wasn't a grasshopper to be found. Michael Holley www.swtpc.com/mholley

Restoring a Macintosh Backup

by KVanMersbergen＠RandMcNally.com

I have a tape that contains the backup of a Macintosh 8100. I have tried to use Retrospect to restore it but it doesn't recognize the tape as a valid format. I did a raw restore and the header does mention "Macintosh-BU1" and also "BackUp- 01.74" The tape was made in 1995. Anyone know what program I can use on my Mac to restore this tape? -Ken V. *************************************************************** This E-mail is confidential.

vt220 question

by jwest＠classiccmp.org

Ok, the post from Kevin reminds me of a VT220 question I've been wondering for some time. Is there a "BREAK" key on the vt220 terminal???? I can't find it, nothing is labelled "break". I'm not looking for a key combo that interrupts a specific host platform like ^C or ^P or something, I want to generate a real electrical "BREAK" signal via the keyboard. What is it?

new 8in floppy disks

Is there a source for new 8in floppy disks? New old stock is fine. I just would like a box of unused blank disks. Two reasons, first I have a STD bus computer with a Z80 CPU and dual 8in drives (one that does not work) that I might like to play with. Second I have an IBM S/34 that has an 8in drive and I need a box of disk for someone to copy some disks for me... -chuck

Lotus 123 Government Edition?

by rigdonj＠cfl.rr.com

I picked up another load of early PC software last week. Everything was in nearly new condition :-) :-) One of the things that I got was a package of Lotus 123 version 2.01. It's marked as a Government Edition and has an eagle of the disk labels. Anybody know what this is all about? The manuals seem to be standard and don't say anything about it having different features. However I'm thinking that it might be a non-copyprotected version. Joe

DEC VT102 question

by jwest＠classiccmp.org

I have a DEC VT102 terminal that I got some time ago from a listmember. On the right of the keyboard where the numeric keypad is, the keys don't match the color of the other keys on the keyboard. The upper left key in the keypad is gold, and the other keys on the keypad are different colors - red, blue, white - and have editing words on them, I think words like "left, copy, print", something like that. My question is - is it likely that someone scavenged keys from another non-vt100 keyboard to replace missing keys, or was this some option used with some word processing software? If the later, I'm happy I have something unusual. If the former, I am going to yank those keycaps off and scavenge the "correct" keys from one of the other VT100's I'm going to junk. Anyone know the answer? Thanks! Jay West --- [This E-mail scanned for viruses by Declude Virus]

Televideo 910 question

by jwest＠classiccmp.org

My, I'm just full of terminal questions... I have a Televideo 910.. maybe it's a 950 but I think it said 910 on it. When the terminal is just sitting there with stuff on the screen, no data is being sent or received... it will suddenly flip to a "previous screen" all by itself. I don't know if the terminal supports multiple pages of display memory, but the symptom is as if it does support multiple display memory and spontaneously all by itself it switches pages and I see data on the screen that came by a while ago. Can anyone point to a likely culprit that may be causing this? The terminal itself is in perfect mint condition so I hate to get rid of it but this problem is annoying!

Cool stuff!

by rigdonj＠cfl.rr.com

About a month ago I picked up what I thought were a couple of HP-IB disk drives made by a compnay by the name of IEM of Ft. Collins Colorado. I searched the net for information about them but didn't find anything useful. I also posted message here asking about them but didn't get any replies. Last week I got one of my PCs up and running with a HP Hyper Viper card (a HP 9000 300 computer on a card) in it so I decided to use it to check out some of the HP-IB drives and such that have been piling up around here. I found a couple of sites that said what kind of MO disks were supposed to be used in the IEM MO drive but I didn't have the right ones so I stuck in a HP MO disk that I had laying round. It worked! The system thinks the drive is a HP 7935 with 404Mb capacity. Flip the disk over and you've got another 404Mb to play with. Not bad! The 2nd IEM drive turned out to be even stranger. In addition to the HP-IB port it has what looked like a SCSI port on the back. It has a LCD display on and it keeps saying off-line. There are also three buttons on it marked Select, Next and Previous. Pressing the buttons did nothing except make the display say "Next Pressed" etc. I finally turned it off then held down the Select button and turned it on and it came up in a demo mode. It says that it's a "Rewriteable Optical Jukebox Controller"!! It says that it's compatible with the HP 1000, 3000, 9000, etc etc and that it is CS-80 and plug and play with MPE, HPUX, Pascal BASIC, RTE, etc etc. It also says that it supports the C1700/C1701 HP Library System. So it's not a drive after all. (I never opened it up, I just assumed that it was!) That also explains why it has a SCSI connector on it. Anybody here have any experience with optical jukeboxs? I've done a lot of searching on the net for IEM but it appears that they're long gone. I found phone numbers for them but didn't get an answer on either one. I didn't find ANYTHING about the jukebox controler but found a couple of sites that gave cross references for disks that can be used in the MO drive. Of course I'm not using any of those disks but it's working! Joe
