So... the 8200/DWBUA saga continues... I got a replacement T1010 module.
It passes internal tests unlike its predecessor. It does not pass
all diagnostics (no yellow LED). The two error codes I see in GPR0
(General Purpose Register 0) are 12 and E. Code 12 means that the
DWBUA could not cause the M9313 UET to respond to an interrupt cycle.
Code E is a register-communications issue. The DWBUA won't pass
diags unless an extensive set of conditions are met, including full
communication with the UET. Before anyone asks, there is nothing on
the Unibus except the UET and a full boat of double-grant cards.
At this point, I suspect the DD11DK, the M9313 UET and/or the cables.
I have three M9313 modules. One consistently generates a 12, two
generate an E. What's not clear to me is if the tests are performed
in numerical order - i.e., the "12" UET is working "better" than the
two "E" UETs. I cannot guarantee that any of the UETs are fully
functional.
I have no Unibus VAXen (out of storage and set up) to test an M9313. I
could set up an 11/04 to tweak at the registers, but that's simple
CSR poking, not full diagnostics. If there's anything related to
XXDP and a UET, I guess I could try that (I'd have to either dig out
my RUX50 or get XXDP onto 8" floppy somehow, unless I can get it on
an RL01 or RL02 pack - I have an RL02 and RL11 right here).
Anyone with any substantial DWBUA experience? I have the tech manual,
but in the past, I just plugged it in and it worked. Didn't have to
go at it step-by-step.
Ideas? Source of working UETs?
Thanks,

I'm looking into ways of setting up a "poor mans 3.3 developer toolkit" up
on a NeXT slab which currently has 3.3 user installed on a 100Mb hard disk.
Before I get too into the idea I thought I'd better ask if anyone on the
list has already tried and failed :-) I'm guessing that all I *really* need
are the includes - the libraries are already installed, and IIRC I can
cross-compile GNU tools on a Linux box (any idea what versions of compiler
etc were supplied with 3.3 Developer?). I'm happy to archive apps to floppy
to free up a bit more space if required. Any thoughts, NeXT fans on the
list?
I know it's probably easier to trawl for a copy of 3.3 Developer and just
install a bigger hard disk, but this way seems a bit more fun :-)
TIA

Hi,
For those of you following the saga of my attempts to resurrect my HP-IPC
here is the latest update.
I have managed to create diskettes that the IPC can read by using an
original 720kb PC compatible diskette drive and original double density
diskettes. I used OpenBSD (any Unix-like system should also work) and
the command dd if=IPC-IMAGE of=/dev/rfd0c to copy the images I downloaded
>from the network to the floppy. Although some of the images did not work
first time (and OpenBSD refuses to write to IPC formatted diskettes) I
eventually managed to get most of the usefull files to IPC formatted
diskettes (by going through the IPC).
My next step is to see how to address HP-IB peripherals from the ROM BASIC.
I tried to use the following Series 80 program from the SERIES 80 HP-IB
Interface Owner's Manual
Original program:
10 S=7 @ ! Variabe S is select code
20 SET TIMEOUT S;500
30 ON TIMEOUT S GOTO 100
40 FOR I=0 TO 31
50 DISP "SPOLL DEVICE # ";I
60 S1=SPOLL(S*100+I)
70 PRINT "DEVICE ";I;" PRESENT"
* 80 NEXT I
90 STOP
* 100 ABORTIO 7
110 PRINT "DEVICE ";I;" NOT PRESENT"
120 GOTO 80
130 END
To get it to run on the IPC I added the following 2 lines
12 MASS STORAGE IS "/dev"
14 ASSIGN 7 TO "hpib"
Now the program runs but reports all 32 devices as present(!)
I only have an HP-9122D dual diskette drive at address 1 and
an external printer at address 5.
Any clues?
Thanks

And if any of those 3ATs need a new home... 8-)

Yeah but I'm quickly learning that these machines are *cool*. My
new 3CT with its 66MHz clock is *screaming* fast! These processors
are *incredibly* clock-efficient. Now I want MORE! 8-)

If all you want is a straight copy of an RT-11
disk and you are using OpenVMS, why not use
BACKUP/PHYSICAL?
I would suggest:
$ BACKUP/PHYSICAL device: filename.BCK/SAVE
This would save your floppy contents in filename.BCK.
Then restore with:
$ BACKUP/PHYSICAL filename.BCK/SAVE device:
I don't have the necessary h/w anymore to
try this, but it should work. I've certainly done
something similar with RX50 WPS floppies and I've
seen others do the same with DECmate III floppies.
The added advantage is that you end up with
a block-by-block copy of your floppy that
you can save on CD or whatever.

Well, thanks everybody for enlighten me.
Edward (too!) and I will take together at least 3 RM03's.
I checked the PDP11 Peripherals handbook 1978-79
to see what is written about the differences between
the RM02 and the RM03.
Edward wrote already that the RM02 was for all PDP-11's
except the 11/70, and that the RM03 was specifically for
the 11/70.
Furthermore average seek time and latency are identical,
however, the peak data transfer rate for the RM02 is only
806,000 bytes/second, where the RM03 has a peak rate of
1,200,00 bytes per second.
That is why DEC saw the RM03 (according to the book) as
the high performance storage for database applications.
More (difference) info on both drives for completeness:
RM02 RM03
rotational speed : 2400 rpm, 3600 rpm
max latency : 25.9 msec, 17.3 msec
avg latency : 12.5 msec, 8.33 msec
max start time : 25 sec, 35 sec <--- not a typo!
typical start time : 15 sec, 25 sec <--- not a typo!
Thanks again for the good advice. I will grab 'm !!
And Tony, "you speak from my heart" as we in Holland say.
Nothing can beat the sound, smell and certainly the looks
of any blinkenlight PDP, IMHO...
