Visual Basic Question

by dj.taylor4＠verizon.net

I have a software driver for an old scientific instrument that is described in a brief manual this way: "The acquisition driver is a tool that allows developers to write their own Windows based programs that can acquire data from any Michelson series spectrometer. The programs can be developed with any programming environment that supports calling standard Windows 16bit DLLs. Examples of such environments are Visual Basic and Visual C++ from Microsoft ( up to version 1.5 ), Delphi and C++ >from Borland, Labview from National instruments. This document assumes that the reader is familiar with all the concepts surrounding DLLs and Windows programming. It is a reference guide that explains the parameters of the functions that make up the Bomem acquisition driver and how they are used to acquire data." I recently purchased Visual Basic 4.0 Standard Edition, but the first pages of the reference indicate that it is a 32 bit only version. Which version of Visual Basic will allow me to call this driver?

M9301-YB Bootstrap/Terminator ROM dumps / listings?

by jnc＠mercury.lcs.mit.edu

> From: Jorg Hoppe >> Here's what I have so far: >> http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/M9301-YA.mac > Thanks for that effort! Eh, de nada. Interesting and educational. > The M9312 code should be similar, at least it may expose some ideas Some parts of it (e.g. the CPU diagnostic) are mostly identical (and the comments there, particularly on the single-op register instructions, are useful to total understanding of that code in the M9301); but alas, I had already done that part of the M9301 (at least, at a surface level)! Much of the M9312 (including the functionality of most of what I had yet to read in the M9301) was quite different. I did manage to get the 'print number' code out of it, but that was pretty much it. So I've done a lot of the remaining M9301-YA code (new version uploaded to location above); not the per-device code, I'll probably blow that off, but other than that, only a few tiny sections remain to be understood. Can someone with a M9301-YA please verify for me that location 165450 contains 0770? I think that perhaps that is wrong, because the code makes no sense if that's correct - maybe a bit has been dropped, or something? And if anyone has a good M9301-YB, I would appreciate a dump. (I do have one, but don't - yet - have a running UNIBUS -11 to plug it into.) > From: Don North > I've had two DL11-W in my 11/34A BA11-K box for years and have never > had an LTC issue. I suppose if you had a a larger number (say four or > more) you might possibly see an LTC issue Hey, all I know is what's in the manual (which Josh posted). :-) I'd forgotten there was a jumper you could pull - I tend not to like to do things like that as it makes the cards non-pull-and-plug interchangeable. Hence my suggestion to 'just use an M7800'. Noel

Old terminal avaialble in Houston

by nospam212-cctalk＠yahoo.com

I have an old terminal available in Houston. It is a red terminal with Bendix and Logicport 2 printed on the front next to the side of the screen and an acoustic coupler on the top. It comes in a big red carrying case. Need to move this out if anyone is interested contact me off list otherwise I guess I'll have to take it to the recycle center. Would rather see it go to someone who could use or enjoy it. David Williams www.trailingedge.com

Obsolete computer discs, etc.

by bob＠warriston.freeserve.co.uk

Second time of sending. A response, please. While turning out my attic I unearthed obsolete *discs for a 1980s Amstrad computer *which has long been disposed of. One disc is, as far as I know, in mint condition but a further twelve contain programmes. Another six discs contain long forgotten person data which I can't access. I am intrigued to know what they contain. Also in my searches I have found a *Microsoft Works manual* complete with system discs, and an *Amstrad user's manual*. Also about a*dozen 5" discs* containing stock records of warehouse long demolished. Again, I am curious to see what I recorded 30 years ago. I am reluctant to consign these items to the dustbin if a) the discs can be deciphered, and b) they are are of use to someone else. Your organisation has been suggested as a possible home for at least some of these items. Are they of interest? If not, do you know any organisation that might be? R.J. Rickard. Edinburgh.

HP (3rd party) id help?

by jwest＠classiccmp.org

I don't think I ever asked this here, I apologize if this is a repost from long ago. I don't remember the answer in any case! In high school we had an HP 2000/Access system, and in one of the racks was a non-HP modem or leased line unit that supported multiple lines (maybe 16-ish ISTR). I remember there was a row of silver rocker switches (one for each channel). I think there was a rotary thumbdial on the right with numbers on it to select the line, and maybe an LED above each rocker switch to show which lines were in use. Maybe (not sure) there were some status LEDS on the right that showed status for whatever line was selected with the thumbwheel. I have a picture of the system racks at https://www.flickr.com/photos/131070638 at N02/17325691225/ In the dual bay HP on the right, it is the left rack, 2nd from the top. It's just under the 2748B paper tape reader and just above the 7900A disc drive. I was curious if anyone recognized definitively what brand/model that device was? Most unfortunately, that picture includes me holding a trophy for a programming contest and it shows I once was thin, once had hair, and always had acne LOL Kinda wish I had cropped it before uploading :\ I apologize for the fuzziness, it's a picture of a picture and the best I could get. The time period is roughly 1978-1982, and I think the system was a few years old already at the beginning of that period (was probably used and put together >from parts at other schools). Anyone know for sure on the comm device? J

Apple iBook G4 running Linux for sale

by shawn-gordon＠cox.net

I have Debian/Gnome installed on it, 1.2gb RAM and 56gb HD. I never configured the drivers for the wifi but a network cable works, shouldn't be hard to get the wifi working, I had it working with a different distro but swapped it out. Anyway, have a soft case for it and selling for just $80 plus shipping.

General Electric Terminet HP 2762A

by jws＠jwsss.com

I recently acquired a GE Terminet 300 in the guise of an HP 2762A terminal, KSR. I am attaching what I have so far in my blog. I've found little on the technical side for this terminal. If anyone has a manual I'd appreciate a copy. It is referenced in one listing of HP manuals, 02762-90001 the service manual. I'm not sure what to make of the one hit I get on that P/N that isn't bitsavers mirrors. I figured I'd ask here first. I'll also ask on the hp equipment group, I am on there too. hpmuseum.net is welcome to my photos, or contact me offline, and I'll make some better quality shots for your web site. I plan to get this going to use for the Multics Simulator at some point. The TN300 was a common console, and was an early symptom of the featureless, non-blink'n lites type shop that came to be. I know the Honeywell 6180 that ran Multics had an 8 panel service panel with wonderful sets of lights, but it was hidden in a cabinet, and typically not accessed by the operator. thanks Jim http://jimsoldtoys.blogspot.com/2015/04/2762a-terminal-printer-ge-terminet-…

Ridge 32/330 up and running!

by derschjo＠gmail.com

Hey all -- Last summer I picked up a Ridge 32/330 that became available locally. This is a fairly obscure early RISC machine intended to be a competitor to the VAX, it uses a 32-bit CPU at 12.5Mhz built from discrete components (spanning three large PCBs). Mine's outfitted with 8mb of ECC memory, Pertec, SMD and SCSI QIC controllers, and Ethernet. You can see some pictures of this beast at: https://plus.google.com/117997069161125071032/posts/JtsR3BokUxp?pid=6063976… I got it running late last year after rebuilding the QIC tape drive and dealing with some intermittent failures due to a couple of low-quality DIP sockets. I now have a set of dedicated 20A circuits installed in my basement so I can run it for longer periods of time without worrying about burning my house down, so I'll be running it for the next couple of weeks just for fun to keep the basement warm and run up my electrical bill :). It's currently running RX/V 1.1 (Ridge's UNIX variant) and it's on the Internet (indirectly, since exposing a 25-year old UNIX directly to the 'net seems like a bad idea). I thought maybe some people here might be interested in checking it out since it's pretty obscure, if you want an account to play around, drop me a line and I can hook you up. I don't know of any other Ridge machines out there (running or not) -- if you have one let me know, there's very little information out there on these things. I'll add that I'm looking for an external SMD cabinet and cabling so that I can image the original SMD disk that was in the Ridge when I got it; it looks like it contains a valid partition table, but it will not boot. I didn't want to wipe it so the Ridge is currently running off of a spare drive -- I'd like to hook it up externally to dump an image from the running RX/V system. If anyone has one to loan (preferably within driving distance of Seattle) let me know. Once that's done, it's time to figure out how to get the Eagle that came with it running again... And a huge thanks to Al Kossow for archiving the OS media that's on Bitsavers, without which this machine would be a very large boat anchor taking up many cubic feet in my basement. (If anyone has any media or docs for this that aren't on Bitsavers, let me know -- I'm in particular looking for an ROS distribution on QIC media...) - Josh

Qualstar 1260 9 Track Tape Service Manual with Schematics

by marc.verdiell＠gmail.com

Question for all in general and Al Kossow in particular... There is a scanned version of the Qualstar 1260 Service Manual on bitsavers, but it cuts off right where it gets interesting, just before the schematics in Appendix C... Does anybody have the full version somewhere with the schematics at the end? (BTW, the 1052 manual version has the schematics). The Qualstar tape drive in question hooked up to my Mac SE/30 (of all things!): https://www.youtube.com/watch?v=YqIrMXxPGUA But it misbehaves now (squeaks while motor reverses and fails reads test, hopefully mechanical?). And my second unit caught another virus and now refuses to load tape or get the motors going. Both used to work fine. Time to open them up I guess. - Marc
