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.

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.

Sioux City hamfest

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
