? 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
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?

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.

OK, now here are some pics that should be available to everybody. I hope.

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.

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. :-)

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).

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.

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.

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,

Apparently Jerome Fine has not posted anything since July 2016. I believe he is/was retired and fairly old, it might be that he is deceased.
