I have a couple of 8" floppy disks. I believe that at that time they used 8560 Tektronix system with Tnix OS for these floppies. Now I want to transfer data from those floppy disks to different media. It is hard to find a service that does the data conversion from those floppies. Does anyone have any recommendations? Thanks for a million times

RT-11 - An Open letter to Mentec?

by dburrows＠netpath.net

I am actively involved in the hobby program with Mentec. ( I even managed to drag a couple other members of the list into it) The RT11 release is just waiting for one last update for something that will be on the CD. All of this probably would have been completed over a month ago but I had a major fire that destroyed my office and storage buildings at the end of January. ( You don't even want to know the amount of DEC equipment and docs that were destroyed - over 3000 sq. feet of tightly packed racks and shelves) this ranged from 11/40, 11/04 through 11/93's, M90's, M100's, numerous VAX's up to and including a couple 4705A's. Needless to say this has put me WAY behind financially and with the regular customers I support. I will be announcing it here when it is official but in the meantime please go easy on Mentec. It ends up trickling back to me and I am doing as much as I can, when I can. RSX and RSTS will follow as my time ( and the others involved) permits. Also don't expect them to be willing to put any time or effort into support of hobby users. If you want support then you need to be a real commercial paying $$ customer that pays for the consulting time like many of us here get paid that are consultants. Dan

RT-11 - An Open letter to Mentec?

by jhfine＠idirect.com

Is this a duplicate message? I sent it at 16:04:04 - 04:00 (EDT) just over 92 minutes ago! Either <classiccmp(a)classiccmp.org> did not receive it or (more likely) my ISP did not send it! Or my ISP lost the reply! The test message I sent at 17:12:55 took about 20 minutes round trip - not too bad, but since it has been over an hour and a half for this message, here it is again! I suspect the most likely possibility is that the original was lost since I have received many e-mails from classiccmp today!!! ----------------------------------------------------------------------------------------- Of all the individuals of whom I am aware of that are still interested in any aspect of RT-11, about half subscribe to this list. Since this is still essentially a private as opposed to a public list (such as a news group), I would like some help plus an opinion on whether or not anyone would still be interested in an RT-11 News Letter? Also, should Mentec be approached to possibly support, provide a forum or at the very least provide its blessing? Obviously, I could just send a brief request via this list along with the "alt.sys.pdp11", and "vmsnet.pdp-11" news groups before I even contacted Mentec to find out if enough people are interested. But if some suggestions and feedback are useful prior to that inquiry, then Mentec might be more receptive. Note that the News Letter could be for both hobby and commercial users. Topics could be Y2K compliance for the hobby V5.03 as well as bug fixes for current V5.07 and enhancements for all versions. DEC used to publish an RT-11 status document each month, but there are obviously no funds as well as no need at this point due to the internet making distribution costs zero. However, I suspect there are not many more years left before interest may dip below a self-sustaining level. Consequently, it might be helpful to find someone who will attempt to assist new converts as well as helping with bugs and enhancements. I know that some interest remains in RT-11 and I would like to pass on my information so that it can be preserved. By the way, has anyone heard anything more about the hobby license issues for all PDP-11 software from Mentec along with anything specific about RT-11? I would appreciate any and all comments along with suggestions on how to proceed with getting Mentec involved (Is that a plus or a minus?) although at this point I feel the chances are very low and I would be more than satisfied if Mentec was just neutral. Sincerely yours, Jerome Fine

NeXT slabs, recent finds and a request

by agraham＠ccat.co.uk

Hi Folks, Curt, would you consider shipping a slab to the UK, and if so how much would it cost me? I think the chances of getting one over here otherwise might be pretty slim! Recent finds: Boxed Atari 520STfm Boxed Amiga A590 hard drive - nice! Like the SCSI out on the back. Odyssey 1 'Baseball' game in practically complete condition Unused boxed Timex Sinclair TS1000 Unused boxed Timex Sinclair TS1500 Unused Timex Sinclair TS2068 - smart :) Even the demo cassette is still wrapped. ICL One-Per-Desk with hi-res monitor in fully working condition; it's even y2k compliant! Mint boxed Sega Megadrive II to go with my Megadrive and MegaCD Commodore CDTV with keyboard and floppy drive - wahey! Another Mac Colour Classic :) I'm a sucker for compact macs, plus it was only ukp10. Mac Performa 5300 Acorn A7000 with monitor and keyboard Acorn A4000 with keyboard (another one) Fileware 'Twiggy' disk for the Lisa 1 :o)) Open University PT502 'Hektor' training machine. Hehe.....goes nicely with the PT501! Requests: Anyone got a spare superfloppy for the Mac Colour Classic? My new one's suffered from the 'dead floppy being pulled out with pliers' syndrome so the r/w heads are munged as is some of the sensory gubbins. And, anyone got a remote control and mouse for the CDTV they don't want any more? <hopes>. My CDTV works fine but it's difficult to use without the remote..... cheers! -- Adrian Graham MCSE/ASE/MCP C CAT Limited Gubbins: http://www.ccat.co.uk (work) <http://www.snakebiteandblack.co.uk> (home) <http://www.binarydinosaurs.co.uk> (The Online Computer Museum, as featured in Computer Weekly!) 0/0

Honeywell Level 6 Stuff Needed

by univac2＠earthlink.net

Does anyone have anything for this computer? It's sitting in our house collecting dust because I have no software for it, and it doesn't have a programmer's panel. I would at least like the full control panel so I could run machine language programs (assuming I can find out anything about it). Every couple of months I renew my interest in my Honeywell Level 6 minicomputer. Thanks, Owen

Technico (Re: TI Minicomputer?)

by ajp166＠bellatlantic.net

The F8 is one I skipped over by choice. I do have basic data on it though. The 8080/8085/z80/z180/z280 and Z800x are machines I'm also familiar with. The only SBC in the 8080 family is the STP cards from VT100s I have gobs of them and they make handy little controllers. Other chips level cpus I've played with include the 8008, 8048/8049 family, 8051, DEC T-11, NSC800, NEC D78xx series, many of the 4bit machines other than intel's.

Fairchild's F8 seems to be the ONLY one you missed barring 6502 and Z-80, which became very popular anyway. I think I have the spec books for most of the chips you list above.

Tek 465/475 scopes are compact, reliable, predictable, and old enough to be affordable. Those scopes are easily the most popular of that era, sorta the Fluke 77 or Simpson 260 of oscilloscopes. Solid, proven design, easy to use, predictable, smooth, bulletproof. If you have a bigger budget, a Tek 2445 is a *sweet* machine, as are its bigger brothers in the 2465 family. I paid about $1200.00 for my 2465A as a point of reference. But if money is a concern, if you can live without fancy on-screen digital parameter display and stuff like that, a 475 (or 475A) can be had for less than $300.00. There's one on eBay right now, two hours left, at $175.00. http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1229127837. -Dave McGuire

50 pin SCSI to 50 pin centronics

by azog＠azog.org

does anyone have a cable that has 50 pin SCSI on one side and a 50 pin male centronics on the other side? I need to connect an alternate boot disk to my VS 4000/60, and I don't want to mess with the existing drives, and it'll only be temporary while I try to fix my mistake in VMS, so it won't be in a box or anything...

Well while picking up a barrel connector I noticed the Nashua store had it on the wall. I think 270-015 is the catalog number. Sheesh, if I do that might as well sent it to me for installation and labeling. Is it possible to read a catalog these days or has the "go ask the web, thin I don't have to work" mentality taken over? Allison

Rescue a system 36

by steve_moser＠parmalat.ca

We have a system 36 #5360, printer 3262-BI and 3 3476 terminals that I would like to get rid of to free up some space. The system was here when I started so I don't know a lot about it, but have found some old documentation. CPU 512K MAG 716MB, it was purchased in June 1986. There is also a bunch of disk and cartridges that I don't have a clue what they are for, but I'm sure anyone interested would know. I am just looking for someone to take it away from our office in Cincinnati, OH. Please e-mail me with any additional questions. Thanks Steve

Photo equimpent for hardware web pics (Re: Technico (Re: TI Minicomputer?))

by cmcmanis＠mcmanis.com

There were a couple of video capture systems for the PDP-11 series, at USC in the image processing lab we built one that digitized a monochrome camera signal. It worked ok, but even better was the Micron drum scanner (boy I wish I had that puppy hooked up to my 11/34!) You can of course get a cheap digital camera (about $500 will get you one that does 80% of what you need) or you can spend $49 on a scanner and using a regular process camera get nice high resolution pictures of your equipment. Further you can hook some scanners up to classic computers to keep it "all in the family" so to speak, take pictures on a classic camera (I love the Leica) and be even better. --Chuck At 12:36 PM 4/13/2001 -0400, anonymous wrote: >Indeed.

Cyber 910

by broth＠heathers.stdio.com

OK, out of the two Cyber 910's I picked up the other day, I have one good machine that is now booting up to Iris. The problem is getting past the root password. Is ther any way of bypassing it or a hack to gain root access from the console monitor? It does have a 150 Mb Archive tape drive but I have no system software for it. Thanks, Brian.

Whats wrong with SMD? It was better than SCSI-1, and SCSI-2. And there was no third party standard for SCSI at all until the late 80s. Even then DEC had far faster technologies and regarded it for low end slower systems. >It was EMULEX, IIRC, that forced them out of the '70's with their >disk drive subsystems.

All the RA8x and 9x were DEC as were the initial RZ2x series and a long list of others. They did off the shelf stuff too but then that was usually for the smaller packaged systems or where time was a market driver. >repackaged drives from other makers, only at 10x the current >price. Those DEC labels were surely expensive. Much of it markup but also a fair amount getting the vendor to fix errors spotted by DEC, getting it to comply to spec and in many cases getting it to pass FCC. Allison

Belle & Howell Apple II

by jss＠ou.edu

I have recently found an Apple II that is a bit interesting. Its color is very dark gray, almost black, and so is the color of the matching Disk II. The labels on both the Apple II and Disk II say "Made for Belle & Howell by Apple Computer, Inc" and have the logos of both companies. Is this a special machine in any way? I don't have it currently. I found it yesterday and have not yet contacted the institiution that owns it to see if is available (though it most likely is). -- Jeffrey S. Sharp jss(a)ou.edu

DC-30 tape ??

by rigdonj＠intellistar.net

I just found several boxes of "Verbatim DC 30 Data Cassette" tapes. I've never seen these before. Does anyone knwo what they're for? In their boxes, they measure 4 3/8" x 2 7/8" x 5/8". The look like an over-sized audio cassette tape. They're driven by the tape hubs and the case does not have a metalbase plate like that found on most data cassettes. There is a note on the back of the tape saying "Do not to record on this side. Side B has a 1600 FCI Pre-recorded clock track for tape speed control". Joe

Some, like the PCPI Applicard, may have more claim to SBCness than others; the Applicard doesn't rely on the Apple for much other than power (unlike the Softcard-alikes which used the Apple's RAM) and I think I remember PCPI demoing one at Applefest in Boston in 1982 by way of having the card out on the table with a 9V battery hooked up to it via clip-leads.
