Hello All,
Is there someone on the list who can supply me with a photocopy of the
wiring diagram
of the cable used between the reader and the interface? I need to
fabricate the cable.
If you have some punched cards as well to spare that would be great!
Thanks,
Ed

Well done! You've fixed it ;-) Seriously, it's often stuff like that
which catches us out. On the positive side, you've learned a few things,
and had a bit of fun (depending on your definition of fun).

Probably, but I'm not sure what :-) You could try halting it and see if i
always halts in the same place(s). If so, it would be worth looking to see
if you can figure out what instructions it executing at that point. It
might be a WAIT or a polling loop. Also look at the vectors in low memory
(from locations 0 to about 20), and the vectors for the devices you have in
the system. They should point to somewhere in the program.

Sounds like you have it set up correctly, at least as far as addressing is
concerned.

The order of the modules shouldn't matter, though it's best to have
CPU-memory-serial followed by whatever device needs highest priority
response. I expect the DSD RX02 controller works just like a DEC one as
far as addresses and interrupts are concerned, so that's unlikely to
matter. The BDV11 is another story, though. It includes a line-time
clock, and your system may need that. IIRC, it's controlled by a
combination of a switch on the BDV11, a bit in a register on the BDV11, and
the LTC switch on the front panel. All of those have to be enabled, and
the BDV11 must be present, for the clock to run. I have seen systems that
boot but then hang if the software needs a clock but it's not present or is
disabled.

Ah, that's the rub: I'd been expecting to see a security bit
shaped like the triangular hole, but you're saying the
tri-wing (with three vanes from the center) is the proper
bit for those screws...

The ez way to tell an RT mouse is that it will have 2 round buttons like
eyes. There is an RT newsgroup that has ontopic postings every once in a
while so you can ask there for questions. Did you get the desktop or tower
form factor? Desktop can only have 1 drive AFAIK. 16meg is the max mem i
believe. Mine has a MDA so I can run text only but am getting a Megapel for
it soon. Not rare machines, but I've never seen any besides the one I have.
I'd hate to pay shipping for it though, extremely heavy!

This is kind of a special score. I never used computers at all till
late '95, and started building my own in '96. That spring, I went to
pick up a video card from a guy who had an RT 6151, and it was the first
time I really grasped that the world wasn't all Mac & PC. I've wanted
one ever since.
I guess all things come to those who lurk.

Excellent! Now maybe I can get an account on it! 8-)

Had Bosch come up with EFI already by 1968?
Every VW (and Audi & MB, etc) of that vintage that I've seen used
CIS, which was a purely mechanical system.
I have seen a 1969 Audi Super 90 (wagon) that had an aftermarket
Capacitative Discharge Ignition (CDI) System... by 1974, Audis
had those as stock, while CIS was still 1 year off...
My 1986 Audi 5000 CS Turbo Quattro uses a Motorola 6802-based
controller... very simple to upgrade, too.... ;-)

Hey folks. I'd like to find a DEC VR160 monitor (19" mono) at some
point. Does anyone have one that they want to get rid of?
