Need a supplier for 80-pin IDC ribbon plug ...

by gunther＠aurora.regenstrief.org

[now that classiccmp posts my messages again, let me try again. I am really desperate about this one.] Hi, I just received two fine boards that need to be connected to one other board each, through a very short cable, which is a 80 position ribbon with 0.025 in pitch (the small pitch) and an IDC female connector on each end with 2 row of 40 holes at a distance of 0.05 in between the holes. Turns out that most suppliers stock maxes out at 64 pin IDC sockets, and the rest is special order with crazy prices $3 to $22 and wild minimum orders of 23 to 100. So, who knows of a place that serves small customers? (I need 10 of these connectors maximal and maximum 1 ft of the matching cable.) Web sites phone numbers anything. May be it might be easier to find the original DEC hardware, I'm talking about the over-the-top connector of a DEC KA64A to the FV64A, anyone having the FV64A installation guide that tells us the part number of that cable?

HP IPC (update)

by vp＠mcs.drexel.edu

Yes, looking closer at the ROM cartridge I see that the TechBASIC code and version is on a sticker placed over the (larger) HP-UX sticker. I must consider myself really lucky for getting that ROM, otherwise I'd have to write shell scripts to program the IPC :-) I opened the ROM pack and it contains two PCBs, the larger contains the interface holes (where the pins sticking up from the IPC motherboard make contact) and contains the OS ROMs (it says OS ROM on the PCB), while the smaller sits on top of the OS PCB and contains the TechBASIC ROMs (it says OPTION ROM on the PCB). Each PCB contains two pairs of ROMs. OS are ROM0 (high and low) and ROM1 (High and Low). The TechBASIC are ROM2 (H and L) and ROM3 (H and L). Obviously since the ROMs are 8bit and the 68000 is 16 bit you need a pair of ROMs for each bank. The OPTION ROM PCB has a very straightforward interface since it contains just the 4 ROMs. I am not sure of the capacity of the ROMs but I wouldn't think that they are likely to be larger that 64Kbytes each. Now that we can get far larger PROMs, if the images of the SE ROM were available, would it be possible to construct an OPTION ROM PCB with everything in it? > [...] C compiler (I think it includes an assembler) [...] Thats great news I was thinking about setting up gcc on my OpenBSD system as a cross compiler for the IPC, but in that case I'd need to recreate the system libraries and include files. Is there any way you can put them up for ftp? ard(a)p850ug1.demon.co.uk (Tony Duell) wrote: > HPIL is a loop, not a bus (strictly). Guilty as charged, I was over simplifying to the point of being wrong.

I have both the HP-IB and the HP-IL versions of the Thinkjet and the mechanism and electronics of the printer in the Integral are very close to the HP-IL version of the Thinkjet. > If you have problems, then I've repaired enough Thinkjets to be able to > offer comments... Apart of having to clean the printer compartment of ink - unfortunately the IPC was shipped with a print cartridge installed :-( it works all right. However, the instructions for cartridge replacement in the HP-IL Thinkjet manual, imply that a small pad is supplied inside the cartridge packaging. This pad is supposed to be inserted in front of the the cartridge on the print-head. The new ink cartridges I have purchased do not have this pad and each time the machine powers up the Thinkjet deposits a blob of ink on the paper. Anybody knows of what can be used as a replacement for this pad? > This surprises me. A 1.44M drive _using 720K disks_ should have no > problems. Me too! I am routinely reading and writing 9114 floppies on my laptop but the IPC drive is particularly difficult. In the beginning I was really lost because I would prepare floppies and the IPC would just say no. At one point I thought there was something wrong with the drive itself. Once I got the 720K drive for my PC, the IPC capitulated. One interesting point is that using my "Unix" system (OpenBSD 2.9) I can dd images on a new 720K diskette (i.e. formatted for the IBM-PC) but the OpenBSD system barfs when I try to do the same on the same floppy once it has been formatted by the IPC. I have excluded alignment problems because I also have an 9122D external drive and have done tests with floppies prepared on these drives. Now that the IPC is usable, I am going to do more tests once I have some spare time. **vp

by wonko＠arkham.ws

i was poking around the one box of docs that came with my PDP-11/34a that i picked up a couple months ago, when i found the 11/750 Field Maint. Print Set as well as the KA750 Field Maint. Print Set. i mentioned this to Dave McGuire who said someone on this list was looking for power supply info for the 11/750. if you still need help, contact me off-list and i'll give you whatever help i can. cheers, -brian -- "Today, put your best foot forward.

What's wrong with the classiccmp list server?

by gunther＠aurora.regenstrief.org

since about 1 or 2 weeks classiccmp seems to silently discard my postings without any error. What's wrong? Am I the only one who has that problem? 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

MicroVAX-I VMS support?

by ajp166＠bellatlantic.net

4.7 should be doable, 5.x not likely. The biggest problem with MV-1s I've seen is it's hard to get enough memory in them. I'd say for 5.0 4mb is really running too close to the bone.

Canon FV-540 Still Video Floppy Disk Drive on eBay

by jfoust＠threedee.com

I put this circa-1991 item on eBay, it looks like it's going to end at less than $10. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1345799733 I'm auctioning a batch of other computer-related items, but this was the most classic or obscure. - John Canon FV-540 Still Video Floppy Disk Drive This was used with the Canon RC-540 Still Video Camera, an early digital camera dating back to 1991. It was part of Canon's Professional Still Video Imaging Kit, a $4900 package. It stored images to a 2" inch floppy disk, and you'd move those floppies to this SCSI device to view thumbnails and retrieve images using Canon's SV-Scan software or other packages. Each could store up to 50 images at low resolution (72 DPI) or up to 32 images at high resolution (150 DPI). I will include a Zip file (Wfvscan2.zip) containing Windows FV-Scan software, which requires a Corel or Trantor SCSI card interface. I haven't tested it. I think there was Mac and even Next software available for this unit. Perhaps you can find it on the net. The box has S-Video in, and composite in and out, and two SCSI ports.

MicroVAX-I VMS support?

by mcguire＠neurotica.com

Can anyone tell me the latest release of VMS that will run on a MicroVAX-I? The last one I ran had 4.5 on it, but I'd like to run at least 4.7 or 5.x. Thanks, -Dave -- Dave McGuire "Hush and eat your vegetables, young lady!" St. Petersburg, FL - Mr. Bill
