Anyone have a copy and can scan part 2 of the article on the Dragon 6809
coprocessor for the BBC micro which should be in there?
I've got the August copy that has the first part of the article but
haven't seen the second part that's supposed to be in the following month...

Without thinking much about it, I'd say that mounting any
real blinkenlight console on a 11/44 is *not* trivial!
Of course, grabbing UNIBUS address- and data-lines and wiring
that to the lights is trivial, but to get all panel functions
(LOAD ADDR, DEP, EXAM, etc). working on an 11/44 is more work.
I guess there are more people on the list who have a boring
PDP-11/44 with a dull panel, that would like to make the /44
more sexy with an 'appropriate' panel. The "upgrade" is,
of course, done in such a way that it can be undone ...
I (we) do not have a /74 panel :-( , but I'd like to hear
what approach you are thinking of, Don.
Hmm, you could do it like I did as add-on to SIMH. Hardware
with some intelligence reads the front panel and translates the
switches to messages in ODT syntax which are send to the 11/44
monitor program ...

Hah, still a good thing that you replied Zane!
That last URL was new to me ... but then again,
it is quite a new page. Thanks!
If I get the 2113E or 2117F console panel working with the
Blinklight board set and SIMH, I will let you know!
Thanks for mentioning me on the pdp8 page :-)

Some people don't have any decency at all.
Perhaps somebody else, better versed in English than I (me?),
could wite him something like:
"I was tempted to open the bid at $199, but then I noticed
the discoloration by the sun of the spine of the book.
The spine should have the same color as the cover. I know
that this color turns blue if exposed (long enough) by sunlight.
I don't consider *this* book in "very good condition" as you
describe in the auction. Thanks, I pass."

Hi,
Sorry to bother you, but I just saw a question you asked on classiccmp.org
about programming a 1702 on a Prolog M900 machine.
Did you ever get an answer or figured out how to make it work ?
Cheers,
Serge Roube
All:
On one of my 8" SSSD drives I noticed that the pressure pad on
the arm opposite of the disk head is worn and making marks on the disk
media. What can be used to replace this pad?
Thanks.

I don't have R-E handy, but "Mac's Radio Service Shop" shows up in the

Radio-Electronics Magazine?

I don't remember which was missing, either +15v or -15v. It was
a long time ago. I removed the one brick and checked that. Checked
everything I could. Someone suggested it was probably in the PCB
where the power switch is. I removed it, but because of the way
it's installed it was hard to check. I happened to have a second one handy so tried it and it worked. It's been running fine since then.

I forgot to note, I replaced the H745 module with a known good one, it
didn't help.
