Somewhere I have a light pen kit that was used to emulate certain types of IBM terminals. Many hospitals used light pens to move through the menus for patient registration and order entry.

Starting the GUI in Solaris 2.4

by cryhavoc_q＠hotmail.com

Bill, I tried that. I navigated to /usr/openwin/bin/ and typed openwin at the # prompt. The OS returned the message "openwin: not found" :-( Ideas? Thanks, Drew p.s. - I'm logged in as root if that makes a difference. I'd also like to set up a seperate user account... I'm going to try to look around for a way to set up a user account. >/usr/openwin/bin/openwin should work... if you didn't install CDE. >CDE is usually on an additional CDROM IIRC... been a long time since >I've seen Solaris 2.4. >Bill _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Recent transputer finds...

by rmeenaks＠olf.com

Well, I am back from my trip to London and picked up my 3 boxes. There are *a lot* of vintage documentation on the transputer including but not limited to: full 3L compilers (Pascal, C, & Fortran) with TBug debugger IMSD100 Occam compiler IMSD705B Occam compiler A nearly complete collection of Occam Users Group newsletters A nearly complete inmos tech notes whitepapers, product info on various transputer vendors user guides for various inmos & transtech boards and boxes and boxes of floppy disks contains various transputer programs and support software. Unfortunately, I didnt have enough space to take the floppy disks, so I had to leave it behind in our London office. I got to pick it up later on when I get back there. As for boards, I am the proud owner of: 2 IMSB012 16-slot transputer tram boards 1 IMSB004-4 evaluation board 1 IMSB001 evaluation board 4 TTG1 graphics tram 1 TTM110 T805 + i860 Vector processor tram and 1 M212 disk controller of some sort. Most of the ICs are missing including the M212. Seems to be some prototype or unfinished board. I'll start sorting out these and start scanning a lot of the documentation. The nice thing about these is it is not in book format, so making it a lot easier to scan. Now, I just need some time to actual do the scanning :-( Cheers, Ram PS: Still looking for an IMSB000 - must be quite rare..... -- ,,,, /'^'\ ( o o ) -oOOO--(_)--OOOo------------------------------------- | Ram Meenakshisundaram | | Senior Software Engineer | | OpenLink Financial Inc | | .oooO Phone: (516) 227-6600 x267 | | ( ) Oooo.

Recent DEC additions

by Mzthompson＠aol.com

The latest addition includes three DECstation 5000/2xx's, one each of /200, /240, & /260. Also included was two expansion boxes with two RZ58's, a TZK12 1/4 tape drive, & a RRD42 CDROM drive. Also got a TK50Z-GA, and a couple 90TL DECservers. One machine is loaded memory wise, 288 mb. Another has a couple extra Turbochannel cards. The first is the TCE Option Module. The second is an AV01B. It has 60 pin mini-D and two 4 pin RJ connectors. Some digging revealed it is an "DECaudio card and distribution box (LOFI)". Anybody know anything beyond that? Also got a DEC PC. It is a Venturis, 486/66. It came with a mono VGA monitor. Looking over the mainboard, I found where the pins would go if it had a color option, and there is a place to surface mount what I assume is the additional memory for the color option. Also got two boxes of manuals, and a box of original DEC software tapes. The tapes include two versions of Ultrix and the tape for the 90TL. The box of keyboards contained 9 DEC keyboards, mostly LK201. If this keeps up, I going to have to buy one of those small storage sheds just to store the extra keyboards that seem to keep wandering in. No doubt about it, I got a case of 'mental DECay', and I got it bad. Mike

BBC Micro

by Alan.Pearson＠cramersystems.com

Nice to see such interest in the BBC - I keep forgetting it's not very common outside of the UK. I've got a couple of spare BBC Masters up for swaps if anyone's interested? I'm looking for Xerox technical manuals (see list), software, even hardware if the shipping's not too prohibitive :-) The machines I've got don't have any documentation or software (although you can still buy new Master manuals from 8BS and download whatever you need >from all over the net) - they both have a sticky key or two and could probably do with a makeover. I did a first pass at cleaning them up when I got them but haven't spent as much time on them as I could ("my" Beeb gets most of the attention!). If you're not familiar with the Master, it was the follow-on from the Model B and Model B+. Basically the same hardware as the B/B+ with 128K RAM (paged) and a 6510 in place of the 6502, housed in a bigger case with "enhanced" keyboard (ie a keypad) and a couple of cartridge sockets. All the I/O ports of the B/B+ were retained (disk, RS423, 1MMz Bus, "Tube" etc), and they added a couple of popular application ROMs (View and ViewSheet) as well as the ADFS and DFS filing system ROMs as standard (you had to buy these yourself on the earlier B/B+ machines). For us hackers they added a terminal emulator, upgraded BASIC (BASIC IV) and upgraded assembler, very nice! Anyhow, if you're interested in swapping, I'm looking for the following Xerox manuals: XDE 12.0 Users Guide (or later) Mesa Language Manual (11.0 or later) Mesa Programmers Manual ViewPoint Programmers Manual Pilot Programmers Manual Basic Workstation Programmers Manual Services Programmers Manuals Either hardcopy or original VP softcopy is fine :-) If you've got something I've missed off the list I might be interested, drop me a line.

Update: Re: MicroVAX equipment6

by Antonio.Carlini＠riverstonenet.com

Eric Dittman wrote: > I didn't think the DEMSA would route DECnet; will > a DESNB? The DEMSA was sold as (at least): DECrouter 2000 - Phase IV DECnet router X25 Router 2000 - Phase IV X.25 and DECnet router WANrouter 500 - Phase V (OSI) DECnet router X25gateway 500 - Phase V (OSI) X.25 gateway (no decnet routing) (It's been a long time, so names and numbers are only approximate ...!) There were also variants with different numbers to run on the single port hardware (DEMSB). So there was (IIRC) an X25gateway 100 for the DEMSB. It could also run SNA software but I had nothing to do with that. The original SNA software would have been for a Phase IV environent. There may have been a later version for a Phase V environment but I don't think there would have been a need for that. The DESNB was a MicroVAX 3600 with some sort of IBM channel connect. Basically a DEMSA with a big pipe into the IBM box. AFAIK the only software that ran on this was the SNA software. Antonio arcarlini(a)iee.org

classiccmp list archive, digest changes, and a free offer

by west＠tseinc.com

Greetings! Several changes people have been asking about... here's the status.... 1) The classiccmp mailing list archives at www.classiccmp.org are now reworked and up to date. We are still using hypermail which takes the mailing list traffic and automagically creates the website, organized by year, month, thread, etc. etc. A background process is *STILL* running to populate the rest of year 1999 (other years, including 2000, are already done) but it should be done in an hour or two perhaps (theres a LOT of mail to process in portions of that year). There is a month or two missing, but those months are actually missing from the raw datafiles. I assume that the list was not functioning during those times (before [and perhaps while] it was being moved to my servers). 2) The hypermail task has been set up as a cron job to keep the mailing list archives at www.classiccmp.org up to date without operator intervention. Because the mailing list is hosted by a server sitting right next to the classiccmp webserver, updates to the archive will be especially fast. 3) Previously, digest subscribers could get multiple digests per day if the size of the digest was large (ie. it could be split into multiple emails if the size went over a threshold). Due to popular request, that is no longer the case. The digest will now send only one email per day to digest subscribers no matter what the size. 4) Several people have asked - I don't have their email addresses here... so once again - publicly, to subscribe or unsubscribe send an email to majordomo(a)classiccmp.org. Any list traffic should go to classiccmp(a)classiccmp.org. When subscribing you tell it which list you want to subscribe to, either the normal list or the digest list. Hope this gets everything in order. Once again, I will gladly host any website, ftpsite, mailinglist, etc. that has to do with classic computers at no charge - unlimited traffic, unlimited storage, no fees of any kind. I am currently connected to 5 major backbones via 100mb ethernet (and offer local dialup in over 152 US cities [shameless plug]), so the transfer speeds should be acceptable. The only thing I ask is that if the disk storage requirements are unusually large (say, greater than 10gb) that you buy your own hard drive and ship it to me. I'll mount it in one of our servers and the drive will still belong to you and be dedicated to your use only. If you decide to move, you get the drive back of course. I'll do this for free, I feel it's something I can give back to the folks on the list for all the endless advice I've gotten out of it. Ok, if a few RK05's and 7900A disc drives show up anonymously, I won't complain either <grin, just kidding>. It would be nice if we could get a lot of subsites under the www.classiccmp.org site, sort of like a portal. At the very least we need some links to classiccmp sites there. Anyone care to throw together a main page for this (I'm not an html person, and our webdevelopment staff is working overtime already)? Then all the subsites that folks host on my server could be at www.classiccmp.org/mydecstuff and www.classiccmp.org/hprules for example. Of course, if you want your own domain name that's fine too. Regards! Jay West

thunderstorm damages!

repairing h-scan on a Commodore 1701

by gunther＠aurora.regenstrief.org

Hi, I got a good deal of a Commodore 1701 monitor on eBay, just that it was not well packed and damaged during the USPS trip. Now I have a lightly damaged enclosure with everything inside apparently working except the horizontal scan. The picture is squeezed into one single vertical line in the middle of the screen. So, what's next? Does anyone have a schematics of that monitor, so I could find my way through without an oscilloscope? Any idea how I could get an oscilloscope for repairing this? Any idea where I should start? I once repaired something on a TV set which was amazingly simple, but I'm not sure I can redo that here without help. Thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
