? I have an 11/04 with an RK11-D.? I have a couple of RK05s, but I wanted to test the controller before I start working on the drives.? The PDP11 Diagnostic Handbook says that ZRKJ?? "checks only the drive-independent logic of the RK11 controller. no drive is needed..."? I assumed that meant it was a diskless test, but now I'm not sure that's true.? Can anyone confirm or deny this? Does anyone have a listing of ZRKJE0? ? My RK11-D has the BC11 drive cable plugged into the backplane, but the free end of the cable is just lying on the floor.? No drive is connected.? The test fails with ??? RK11 LOGIC TEST I ??? MAINDEC-11-DZRKJ-E ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177402? 100000 ?177402 is the RKER register and bit 15 is DRE - "Drive Error". According to the manual this bit is set when the AC power to the drive is lost, which given that I don't have a drive at all, doesn't sound unreasonable.? Continuing ZRKJ?? also gives ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177404? 140200 ??? RKCS ERROR ??? ? PC??? WROTE?? READ ??? 002636? 000002? 140202 177404 is the RKCS register and the first two bits are ERROR and HARD ERROR.? These are both set by the DRE bit in RKER and aren't really a surprise. ? I'm starting to wonder if this diagnostic really works w/o a drive attached, or if these errors are expected. Thanks, Bob

Entrex 480 / Digital Computer Controls 116 in New Jersey.

by mattislind＠gmail.com

I just happen to see this auction: https://www.liveauctioneers.com/item/86804138_entrex-480-vintage-computer-e… Looks like three systems. One marked Entrex 480 the others look like the DG Nova clone DCC 116. On top there seems to be a Diablo printer of some sort. Some rust, indeed. In New Jersey. Then there another auction for several Diablo drives at the same location: https://www.liveauctioneers.com/item/86804145_sweda-750-computers-and-vinta… Also a stack of DG like cards and a core memory board, likely DG or DCC. Not in best condition but probably worth rescuing. Maybe someone in NJ area that want it? /Mattis

IBM System/36 5360 For Sale - Alabama

by skynet＠wans.net

I recently found an IBM System/36 5360 for sale, with 5251 Terminal and Keyboard. System is supposed to be in good running condition, taken out of service in September 2019, single owner. Asking price seems to be about 10k (!). Anyone interested should go to this link: Vintage 1979 IBM 5251 Beam Spring Mechanical Keyboard 7361073 System 36 34 | Almost Anything - And then use the chat feature on the webpage - the owner will respond to you with info on the system. I have no relationship with this seller, just wanted fellow collectors with interest in "Big Iron" to know it is available. Stan Irwin

Ancient transistor ?computer board (Peter Van Peborgh)

by peter＠vanpeborgh.eu

OK, now here are some pics that should be available to everybody. I hope. https://photos.app.goo.gl/h64tye8ecmPHQfJD7 Smells of (early) 1960s transistorized. No helpful marking apart from * "GATE JJ01" on SIDE A. (components). * "C NT OL DATA" on side B (solder traces). Big transistors are Motorola "180376008". Also, any ideas what the "246 636 B" boxes are, they have four legs? A curse on TinyURL and praise to Camiel Vanderhoven. peter

Amiga - AmiFast 3000

by healyzh＠avanthar.com

Anyone have any experience with these? When I installed in around ?97 or ?98, it just worked. Now I?m seeing 0 bytes of Fast Ram on my Amiga 3000, I just see 2MB Chip RAM. I don?t even know if I can boot a base AmigaOS 3.1 with Video and Ethernet drivers. :-) Zane

About to dump a bunch of Compaq SCSI disk caddies (and disks)

by julf＠julf.com

Hi! I have a box full of Compaq SCSI server disk caddies (with 9.1G disks in them). Feels silly to dump them into e-waste recycling, but there probably isn't much point in shipping them very far either (I am in Amsterdam). Julf

Original HP MPE and HP-UX install tapes

by steerex＠ccvn.com

Hey, Digging around I found some more stuff that I had forgotten about. Note these are the original, HP 9-track, 1/2 inch, 1600 BPI, tapes. They are NOT copies. All had been stored indoors in a climate controlled environment and should be 100% readable. Some of the reels are 600 ft, some are 1200 ft, some are 2400 ft. -- HP-PA support for the series 800 tapes 1/2 and 2/2 P/N 82436-13500 REV A.B8.00 DATE CODE 3113 support format -- -- HP-UX 8.0 INSTALL HP9000 HP-UX Series 800 tape 1/1 P/N 82436-13509 REV A.B8.00 Date Code 3113 Install format -- -- MPE/V Release 40 Patch for the HP 3000 P/N 32033-10469 tape 1/1 NMSTORE FORMAT -- -- MPE/IX COBOL 5.5 COMP. for the HP3000 6250 BPI MNSTORE FORMAT tape 1/1 P/N B3845-10007 REV A.10.25 -- -- MPE/IX COBOL 5.5 RTS. for the HP3000 6250 BPI MNSTORE FORMAT tape 1/1 P/N B3847-10007 REV A.10.25 -- -- MPE/IX COBOL 5.5 DEV. for the HP3000 6250 BPI MNSTORE FORMAT tape 1/1 P/N B3843-10007 REV A.10.25 -- -- MPE V Release 3P FOS Tape tape 1/1 SYSDUMP format P/N 32033-10452 REV G.3P.00 Date Code 3419 -- -- MPE V RELEASE 40 for the HP3000 Turbo update tapes 1/2 and 2/2 P/N 32033-10461 and PN/32033-10462 REV G.40.00 TU Format (I don't think you can boot this format) -- -- HP9000 Series 800 CUSTOMIZED HP-UX CORE and SUBSYS Tapes 1/3, 2/3, and 3/3 Release 0800 VUF A.B8.00. UPDATE Format I think the customized label is because I had ordered these tapes from HP many years ago. Since support had expired, the additional software that's on the tapes does not require passwords to install. As I recall, the tapes include HPBASIC, COBOL, FORTRAN, RPG, and possibly some other programs. I could be wrong so don't hold me to it. -- -- MPE V Release 3P for the HP3000 SUBSYS TAPE Store FORMAT Tapes 1/2 and 2/2 P/N 32033-10455 Rev G.3P.00 Date Code 3419 -- Feel free to make an offer but, as with my other stuff, I am not giving them away. I suspect these are pretty rare so, be generous with your offers. Because of packing and shipping, I'd prefer to see all of them go to one place. See ya, -- Steve Robertson steerex at ccvn.com
