I have available for those who want them, 3 CDC disk drives (model NSOMPI) with 8 80Mb disk packs. Each drive is approx 8 inch by 10 inch by 27 inch in size and they have an SMD interface. 6 of the packs are brown, 2 are blue. Ed P.S. the drives are in The Netherlands, shipping is possible, but it would not be cheap!. -- edward(a)groenenberg.net | Collector of PDP-11's. http://www.groenenberg.net | Politici zijn vieze oplichters.

HP2100a VS HP2100s

by MGemeny＠pgcps.org

Here?s a question for you guys. One of my HP2000 friends asked me what the difference was between a 2100a and a 2100s. Now, I have done a fair amount of maintenance on both and I can?t recall that I ever paid any attention to any difference between the two. Does anyone know of any differences between the two other than the name on the front plate? Thanks, Mike Gemeny

Anybody have an extra power supply for a PDP-11/04??

by bob＠jfcl.com

I was given a PDP-11/04 recently, in the short 5 1/4" chassis, but it is missing its power supply. Looks like it was removed to use as a replacement for another 11/04. Does anybody have one they don't need? Anybody even know what kind of power supply goes in a 11/04 in the short chassis?? Thanks, Bob Armstrong

RSX11M Boot disk

by Pres＠macro-inc.com

Need some help making a disk bootable under RSX11M V4.6 (not Plus). Need to copy a bootable system volume to another. Usually I use standalone BRU with no problem. Problem (I think) is that I have 2 MSCP controllers, one drive on one controller, other drive on the other controller and their low level formats aren't compatible so can't swap drives around. Unfortunately I have no working tape drive at the moment either. (I do have 5 TK50's with tapes hanging out their mouths though). Dragged out a Cipher 550 cartridge tape drive, plugged in MSV05 controller (MS:), bought some new DC600A tapes after the ones I had in the attic for 10 years didn't work, but it didn't work either. Disk and controller configuration is: An Emulex QD01 controller CSR=172150 Vec=154 (Standard MSCP address) with an RD54 as DU1: This is the system disk and it hardware boots fine into M. And a RQDX3 CSR=172154 Vec=150 (Secondary) with an RD32 that shows up as DU4: under M. I can BAD it, INI it, MOU it etc. -- drive works fine. Using standalone BRU to copy DU1: to DU4: it gives error -65 (device offline - it can't see it) for DU4: Ok, I use CNF to change DU4: to alternate CSR, it give me error -65 on DU1: Apparantly CNF changes DU CSR for both drives. (I did find I could make standalone BRU bootable RX33's though which I did as they boot much faster than TK50.) So, standalone BRU not working as I wanted, I made the RD32 DU4: drive a Files11 volume (BAD, INI etc.) Created all the UFD's from DU1: (system disk) on DU4: (target). (Still haven't found anything better than TECO for making command files >from directory listings, have a PC version of TECO I use today) I then copied all the files to the target disk: BRU/NOI/MOU DU1: DU4: Worked fine. I can mount DU4: and look at all the files fine. But, how do I make DU4: bootable as DU0: on an RQDX3 at standard address of 172150?? VMR and SAV only seem to work on the current SYSTEM disk, not a target. For example, tried to VMR DU4:[1,54]RSX11M.SYS --- no joy. When I try to boot the DU4: on another system, it give me what INI wrote in the boot block: "THIS VOLUME DOES NOT CONTAIN A HARDWARE BOOTABLE SYSTEM" Any suggestions on how to make DU4: bootable? Best I could find Googling was: http://www.miim.com/faq/hardware/diskfaq.html#mscrscpy But I don't see how that effects a drive other than SY: Any help would be appreciated. Thanks, Ed Kelleher

Puget Sound area collectors, heads-up!

by kyrrin＠bluefeathertech.com

Spotted yesterday at RE-PC Tukwila: A nice DEC MicroPDP-11/23 in a four-foot rack, along with two tape drives of a type I've never seen before (definitely DEC'ish, they look like they take a smallish cartridge). Also had what looked like a third-party 16-port serial MUX installed, probably an Emulex or similar board. No price on the thing, but probably available for cheap. RE-PC is at 510 Andover Park West, at the opposite end of the complex from the UPS customer counter. Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

This problem has been fixed, thanks for suggestion from Tony of the UK. -Bill >Do you mean you get thje CASS? prompt when you turn the machine on >without holding BREAK down? >If so, then the machine is not detecting the disk controller (that's why >it's not trying to read the disk).

HP 9133XV disc drive question

by rhahm＠nycap.rr.com

I recently aquired an HP 9133XV combination 3.5" floppy and 15M HD with an HPIB interface and Amigo protocol. I tried to use the drive with an HP 86B and an HP 85B computer. The floppy works fine but the computer will not recognize the hard drive. The HD seems to spin up normally. I tried an "INITIALIZE" command without success. Can the series 80 computers use this large drive? Does anyone know how to use the test function on the drive? Thanks

Origin of row/column based database software

by mikeford＠socal.rr.com

AFAIK spreadsheets are a fairly old engineering practice, originally done manually on paper and slowly ported to automation and computers. What about the old accounting machines, they are sort of spreadsheets.
