Would it be possible (not necessarly legal) to use a copy of RT-11 'for SimH' on the pro-3{5|8}0 ? Also, how would I go about getting data from an RX-50 from the PRO into an image that SimH likes? I've got access to a DOS and Linux box with a 5.25" HD drive that I've used to successfully make copies of RX-50's with teledisk. Is there a readily availble program, or will I have to go play with INT 13h on my DOS machine to try and copy things into an image file? Thanks -- Pat

Non-DEC SCSI tape drives with VMS

by bob_lafleur＠technologist.com

Has anyone successfully used non-DEC SCSI tape (cartridge) drives with VMS? If so, what types have you been successful with? Travan? DAT? 8mm? Which models? I just hooked up an HP SureStore TR4, and it's recognized, the device is an HP T4000s. But when I try to access it (INIT a tape, etc) I get a "parity error". I don't have any Travan-4 tapes though, just Travan-5 tapes, so that's what I tried... Could that cause a parity error?

Zebra Systems (was Re: Timex Sinclair 1000 Update and Questions)

by acme_ent＠bellsouth.net

> From: Gene Buckle <geneb(a)deltasoft.com> > Glen, isn't there a company out there somewhere that is selling unbuilt > kits still? I seem to recall them going for $99. Yes: Zebra Systems in NYC. BUT I suggest you exercise caution when dealing with this firm, i.e., only pay them with a charge card in case they "lose" your order or find they can't provide the products as advertised. I've had a couple of unsatisfactory dealings with them. Another gripe of mine is that in the last three years or so they've bumped the price from $29.95 to $99.95. If you do a search on eBay for "timex,sinclair" you'll often find Zebra selling kits there, usually with a starting bid of $49, so you can save a lot by going that route. The kits themselves (I've built at least two or three) are great. They're not exactly identical to the original retail versions (no original Sinclair BASIC manual, Zebrafied assembly instructions instead of original) but they work, and one advantage is that the RF modulator (if you care to use it -- I don't) is UHF instead of VHF and provides a much cleaner signal.

This last week at auction, I >>picked up one of the oldest cd writers I've ever seen, which is >>ironically made by Philips. It appears to have a SCSI interface, Why is this ironically? Philips and Sony developed the CD standard together, so it would be natural that the oldest writers are Philips and Sony ones. Sadly I don't have one, they were incredibly expensive in those days.

Probably. I've certainly seen the plugs we use, in Germany (or at least, in Austria). Have a look at http://www.farnell.com/datasheets/21296.pdf and see if the picture matches.

Lisa software archives

by Marion.Bates＠Dartmouth.EDU

Hi folks, A few years ago, I posted a webpage about Lisa/MacXL technical info: <http://www.cs.dartmouth.edu/~woz/>. I intend to add more stuff to it...someday. It's still up, but I noticed the other day that the Lisa software archive, hosted on a separate ftp server, was unreachable. I guess the sysadmin closed it down. However I snagged the files from a backup and moved them, temporarily, to my own machine (which has a semi-static IP, broadband). So, if anyone needs a copy of (de-serialized) Lisa Office System, LisaTest, MacWorks, etc. the disk images are now here: <http://66.177.162.74/lisa-files/> The link on the website has been updated as well. If any of you (Sellam?) had listed the ftp link separately, please update. I'll send another note when I have the new, permanent home for these files. Thanks, -- MB

Some Lisa Questions

by jingber＠ix.netcom.com

I have a floppy problem with a Lisa 2/10 (MacXL ?): After inserting a disk, a dialog appears (MacWorks XL) stating that the disk isn't formatted (it is). If I chose to eject the disk, the spindle motor continues to rotate. This doesn't happen during all ejects - it's an intermittent problem, but I have never been able to read from the floppy. This is a 400K drive. 1) I have cleaned the stepper cam, the head, and the ejection path and have lubricated various parts. The head travels properly and the ejection motor is functional. Where should I proceed? 2) The front fascia doesn't align properly due to the front of the 400K floppy protruding a few millimeters. The front will snap into place properly on the left 'catch', but is bulging out on the right catch. I can't see why this is so, as the drive case is flush with the chassis, and there is no possibility of the floppy sitting too far forward due to the recessed mounting screws. The floppy appears to be just too long (?) Has anyone else seen this. 3) Mouse related: How is the mouse supposed to secure to the connector on the motherboard? The mouse has the standard two thumbscrews, but the motherboard is lacking the metal jacket that would normally contain two nuts to recieve the connector screws - it's just the black plastic DB-9 connector. Something seems missing in this picture. Any clues? Thanks, Jeffrey H. Ingber (jingber _at_ ix.netcom.com)

If you run some wires from the pcb to the empty forward part of the shell, and use an in-line female RCA jack, everything fits nicely inside (except the jack) and the wires connected to the RCA jack will easily pass through the shell near the "earphone" jack. > The major question concerns the program tapes.

Finding an appropriate cassette recorder can be a challenge, so I would suggest that you don't hunt for one using tapes of unknown quality. First, try SAVEing a one line program onto a good-quality (doesn't have to be great, just good) new blank cassette. Then re-LOAD the program. Try different volume levels. This is the only way to verify that the recorder is suitable for both operations. Then try LOADing your other tapes. Last time I had to hunt for a suitable cassette machine (four years or so ago) I went through several, including a nice Sony, before I found that the best match was a Radio Shack (can't believe I'm writing this) Optimus. Cost about $40, but worth it if you plan on using the TS-1000 very often. > One of the websites I found last night quotes the promo for the 16k > cartridge - something like "With the addition of 16 kilobytes of memory, > the Timex Sinclair 1000 could conceivably store a program of 960 lines, > but of course. no programmer would ever need to..." ROFL! Which site? The payroll program I wrote and used at Consolidated Electronics was well over 960 lines so I had to use a 64KB pack. For tons of info, links, etc. please visit our ZX-TEAM website at: http://home.t-online.de/home/p.liebert/zx-team.htm For a nice listing of available hardware, try Jack Boatwright's site: http://www3.outlawnet.com/~jboatno4/ Of course, I'll be glad to help you as much as I can, so if you have any questions please don't hesitate.

Sioux City hamfest

by ghldbrd＠ccp.com

Not much to report here, nice turnout, and a few odd items worth noting . . . . . There was a Fluke something, that looked like some sort of terminal that set up data acquisition on an IEE-488 buss. He had the complete unit and software and docs. All I remember is that the CRT had a 2:1 aspect ratio. I'm sure this will turn on some of you obscure stuff collectors. Gateway had a nominal presence there, but nothing worth noting, just some PC stuff. I did pick up a Commodore MPS-801 printer . . . are ribbons still available and for how much??? If I can't get any ribbons, I'll just contribute it to someone who wants to give it a nice home and call the dollar invested a loss. I even found one (wished there were more) AUI to 10 base T transceiver. Now I can check out my Amiga ethernet boards, if the Xcvr is okay . . . . . Two TRS80 Model 100's were there for $50, with books. I was tempted, but I passed them by. I'm sure I'll kick myself later on. One last mention, not in line with this topic, but I do have an original DEC (quantum) 240 Meg HD for trade. I have a surplus of Quantum drives, and I have used this one on my Amiga with no problems. If you want one for your DEC contact me off-list and we'll work out a trade or something interesting. Gary Hildebrand St. Joseph, MO

Timex Sinclair 1000 Update and Questions

by doc＠mdrconsult.com

Well. I was roaming yesterday and found a very nice old Macy's dress box. In it was a TS-1000 with the TS-1016 16k memory cartridge, manuals cables, and around 10 tapes, including PIM apps & games. After soldering a broken joint on the m/b [1], running to WallyWorld at 2:00am for a 300ohm-to-75ohm converter, and finally figuring out that I needed to turn the brightness all the way up on the TV, the little booger works. This is the first computer I've had that was in need of board-level repair to start with, simple enough to ID the problem (and not too densely populated), and common and cheap enough to "risk" non-essential modifications. Texas Instruments trained me as a "Certified Solder Sucker" or whatever in 1982, but I really haven't done any electronics work since. I build cables, solder all the joints on auto work, and stuff, but till last night had truly forgotten the joys of eutectic solder. Also till last night, I had truly not realized how much worse my eyesight has gotten.... The card-edge cartridge connector is worn nearly through the traces on the m/b. If the computer is jostled much at all, it loses the RAM and its little mind. Next mod will be to do some (cheesy, yes I know) wire patching to the finger traces. I joked last night about just going to the thrifts for a $5 B&W TV, but my experience with tuning and brightness matches Jeff Hellige's comments, and I may do exactly that if I keep this. What I'll more likely do is try Glen Goodwin's idea and tap the composite signal off the motherboard. The major question concerns the program tapes. I tried hooking up to my stereo, the only cassette player I have anymore, and at any volume, it just blows the Timex away. The display goes to hell, it doesn't seem to "read" the program, and the display stays scrambled even after the cassette stops. The manual states that a "Hi-Fi" tape deck, as opposed to a cheap battery-driven portable, may be the source of problems. Does anybody have a suggestion or solution? My instinct is that my cheap stereo does enough EQ (not optional) to "blur" the signal. One of the websites I found last night quotes the promo for the 16k cartridge - something like "With the addition of 16 kilobytes of memory, the Timex Sinclair 1000 could conceivably store a program of 960 lines, but of course. no programmer would ever need to..."

That's actually a good thing. If the disk is wiped to the point that it needs a format from the OS, then I can toss the disks in a general use box, and not worry about which OS they are used on (Mac or DOS/Windows). This way, they can be formatted fresh for the given platform they are needed on (yes yes, the mac can read PC disks just fine, but I prefer not to do that for Mac specific uses) >Wasn't suprised to see that it doesn't do VHS tapes very well.

Good to know as a "fact" although I had suspected something like this anyway, so I wouldn't have done it. I also wouldn't have tried it on Zip disks, or Syquest carts or other removable "non floppy" media for fear of the same problem. I suspect it might be ok on Zip disks, but I know those are treated more like a hard drive platter than a floppy disk, so I don't consider it worth the risk. > Bottom line . . . demag a HD and it becomes >a doorstop.

Now OT: Speaker boxes... [was:: I hate Radio Shack]

My head has two speaker jacks, so I can have it see 2 8 ohm speakers, or wire in a homemade adapter so it will see a 2 ohm load. I've been thinking about wiring in some DPDT switches, so I can flip each side between 2 & 4 ohms. Depending on how much you travel with those speakers, here's how I would set up the boxes... - 15" in a ported box, all by itself. It'll be heavy. Nice boom for the bottom end. - 4 x 12" in a sealed box. Good tight response, but still has the bottom. This could be used by itself quite nicely. - 8" (or two) in a sealed box with a good horn tweeter. This would go best used with the 15" cabinet, and an appropriate crossover. Maybe your amp has one built in*. It will also be good for practicing by yourself. Nice & tight response, and great if you play some funk style too. * My Peavey does have a built-in adjustable crossover, but it's pre-amp level. I then have to amp each side after that. One would get looped back into the Peavey, and the other to a second power amp... And hopefully you know the make and model numbers for those woofers. That will be required if you want to build the best boxes possible for them. I picked up the 2 speaker design books from Radio Shack to help with the box design. Blaupunkt also has a basic DOS program to help with box design too. The RS books had some decent rough size info for speakers, so I assumed some average-low specs for my 12s went I calculated the box size. I know the box is a little small for them. you can kinda hear it. But I don't have the test equipment needed to find the real specs for these drivers, yet :) I'm working on a spreadsheet that has all of the formulas built in, to help design different boxes. I'm not sure if I have it finished yet or not, though... -- --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- (203) 432-0953 --- ICQ # - 905818 Mac OS X 10.1 - Darwin Kernel Version 5 Running since 01/22/2002 without a crash

OT - DDS-2 drive errors on Microvax 3100, VMS 7.3

by bob_lafleur＠technologist.com

It seems like we get a lot of VMS questions here, which probably doesn't really fall directly under the list rules. I'm guilty of it too. But there's so much knowledge here, it's hard not to ask. If anyone can point me in the direction of an active VMS mailing list, I'll ask my VMS questions there instead. And if there's not one, I'd consider setting one up if there happens to be any mailing list software that works with Exchange Server 2000. ----- I've got my ARCHIVE Python (model 4326) DDS-2 drive connected to my MV3100. It is connected to that machine only (I don't have it dual-connected, as discussed in another message thread) and it's on my 2nd SCSI controller chain. When I first boot the system, the first restore I do from tape I get this message: $ backup mkb100:rob/save *.* %MOUNT-I-MOUNTED, ROB mounted on _BOB$MKB100: %BACKUP-E-READERRS, excessive error rate reading MKB100:[000000]ROB.; -SYSTEM-F-CTRLERR, fatal controller error %BACKUP-I-OPERSPEC %BACKUP-I-OPERASSIST, operator assistance has been requested I then get "fatal controller error" messages whenever I try to access the drive, until I turn it off and back on. After the above erorr, the device shows 102 errors in SHOW DEVICE. Once the drive is turned off and back on, it works fine from then on, with no problems. If I boot the system, then turn the drive off, and back on, I *still* get this message for the first restore I do. Then I turn the drive off and back on, and all is OK. If the first operation I do after booting is a backup TO tape, it goes fine with no problems. But then when I try to do a restore from tape, I still get the above error. I've updated the drive's firmware to what I believe to be the latest (28388-XXX V5.AQ). Right now I have the drive in an external enclosure to test it. I was going to mount it internally in the MV3100, but if I have to power the drive down to make it work, then internal mounting is not possible. Could it be a SCSI termination problem? The drive works flawlessly on my PC. Thanks, - Bob

IMSAI News?

by r.stek＠snet.net

Bob Shannon - Could you expand on your comments about non-s-100? According to the website, it has a 10 slot S-100 MB, and "The IMSAI SERIES TWO utilizes the powerhouse Zilog Z8S180 microprocessor and provides a complete system on an IEEE-696 compatible S-100 board" I am somewhat interested in the machine, but not if there is NO chance of using some of my other S-100 boards in it.

UCSD P System (was: Why is it that ...

This is NOT the UCSD p-System filer, it's one belonging to a derived version of it that Apple briefly used on the Apple II. To give you a little context, this was version II of the p-System (the Roman numerals denoted architecture versions). The one released by SofTech Microsystems, on the IBM and the Sage and many others, was version IV, and it was a major overhaul. (Status of segments regularised, almost no limit on the number of segments in a system, all units swappable, dynamic linking, instruction set even more compact than before, procedural parameters, conformant arrays, semaphores, processes, etc. etc.) Including using 80 columns on the screens! (Actually you could change that in SYSTEM.CONFIG if you needed to, as seems clearly to have been done with this example). The filer used full names in its menus when it had the screen width to do so. Which was most or all of the time after those very early screens, unless, as I say, you did something to SYSTEM.CONFIG . As for making DOS look good, it made it look dreadful. I still remember the pain of migrating to Turbo Pascal, which was the BEST that DOS had to offer. Tiny file names, NO file typing (file extensions are NOT file types), terribly slow floppies, file volumes WITHOUT NAMES (which continues to this day), every program needing all its code linked into it statically, hence several copies of the same code on the same floppy -- etc etc. (DOS's only advantages: more flexible number of entries in a directory, and borrowing a poor man's version of directory trees from UNIX. The p-System only allowed 77 entries in a directory -- that was from a time when the DEC PDP-11 was popular -- and had only 1 level of "subdirectory", which was an actual subvolume file, of fixed size. And DOS was to acquire networking, whereas work on the p-System seems to have suspended before that could happen.) Oh, and the p-System had powerful wildcards, including use for mass name changes. DOS's wildcards were always weaker, and buggy. And I really did like being able to compile on a 68000 machine and run the compiled code on an 8086. Much faster turnaround time. (I once did a project where we were supposed to use the then-Microsoft Pascal on XT's for compiling -- all in native code of course. We stayed in UCSD Pascal and compiled within the p-System because it was FASTER!) > > >You may remember what those letters stand for, but I don't. > > ... > > > > For those not wanting to chase the link, it says: > > > > Filer: G, S, N, L, R, C, T, D, Q [1.1] > > > > Don't you remember?

PET and Magic Sac+

by foo＠siconic.com

I found two interesting items today. One is a PET 2001-8. It has the regular keyboard. Inside was an "expandaram" board that added additional RAM and some peripheral slots for the PET. The cards plugged in looked a lot like Apple ][ cards in their form factor but I assume this is some proprietary bus. Anyone have info on this? Also, found a little module that apparently plugs somewhere into an Atari ST. It's called the Magic Sac+ and on it it says "Turns your Atari into a Mac". Anyone ever use one of these? Where on the ST would this plug in to? Or is it for the Mega ST perhaps?

"Windows V1.0"

It's not much help, but the first Z248 that we recieved had MS-DOS 3.x and Windows 1.0x floppies included with it. I've never seen a copy of Windows 2.x, however, oddly enough I recently found a shrinkwrapped copy of Windows 1.0 in the trash! On a vaguely interesting Windows 1.x note, the PC version of the game "Balance of Power" included just enough of Windows 1.x to run the game! It was the only use I ever had for Windows 1.x :^) Zane

Sharp PC-5000 (early laptop circa 1983) for sale

by foo＠siconic.com

I'm selling a Sharp PC-5000 that is new in the box. The Sharp PC-5000 was one of the first clam-shell portables circa 1983 (the GRiD Compass and the Gavilan were it's contemporaries, as well as another one from Australia, called the DuMont or something). This is an awesome piece for any collection, especially those who collect portables and early laptops. They don't get earlier than this, and certainly not new, in the box. Pictures: The computer http://siconic.com/crap/sharp5000.jpg The box http://siconic.com/crap/sharp_box.jpg The manual http://siconic.com/crap/Sharp_us_g.jpg You also get a bubble memory module (sealed, new) http://siconic.com/crap/Sharp_Bm_box.jpg Best offer over $250 by Friday (June 17th) takes it. If there are no takers here, it goes to online auction. I accept PayPal preferably, check or money order will suffice if sent promptly. You, of course, pay all shipping charges.

The leads carrying the composite signal are bare, and exposed.

Sure, but if he's having trouble finding a modern TV with a tuner that "likes" the TS1000 (most modern TVs don't), then using clip leads to grab the signal would at least verify functionality of the computer. Bearing in mind that the TS1000 has been described as "common as cockroaches" (Sellam Ismael) and "an educational toy" (Richard Erlacher), plus the fact that the ZX81 was originally sold as a kit and zillions of them were assembled by schoolchildren, I think my advice was reasonably appropriate.
