Well, I've now acquired a PC05 high-speed paper tape reader/punch for
the PDP-11/20 I'm currently restoring. I still lack the PC11 board,
though. Megan's list says the following:
M781 PC11 U PC11 control board for KA11
M7810 PC11 U Paper tape reader/punch controller
Do I *have* to use the M781 version, or can I also use the M7810 if it's
all that I can find? What is the actual difference between the two
boards?
Next: why were the backplane modules mounted at the top of the BA11, wire
wrap up, in the 11/20? It's easy to flip the thing over while it's not in
a rack, but when it's in a rack...
Some trivia: the two partial 11/20's from which this one is being built
have serial numbers 786 and 1102.

I also think it's a good idea. I get pretty fed up with long off-topic
threads especially those of a political nature, though I don't mind the
occasional off-topic post. Deleting a few OT posts is fine, wading thorugh
dozens isn't something I enjoy.

I'll take this even one step further... learning programming
isn't learning how to construct applications. They didn't teach
how to construct applications when I was in school; and now,
with RAD/IDE and class libraries/frameworks, most people never
learn.
Since constructing applications is (generally) platform-dependent,
it might never have been/be appropriate to cover in a college course.
Fortunately, my career path put me in the position of maintaining
systems constructed (or *not* constructed) by others. I found that
I learned how to conceive a large system and implement it by factoring
by immersing myself in a previous system that someone else wrote,
and while immersing myself, watching out for bad habits to be
avoided.

Most likely you're correct, but then I associate BASIC with a full compiler
that could generate 132-column headered listings complete with symbol table
and assembly language output for each statement.
Some 8-bitters *did* boot directly into Pascal... at least I never saw
a copy of UCSD Pascal that was anything other than language environment
*AND* operating system combined...
And as for booting directly into a language environment, any old FORTH
programmers here? At one time, I thought FORTH would rule the world.
One of the rules that would make sense to
me would be that people would stick to plain text
mail, rather than fancy large letters etc.
NO HTML PLEASE

Hear, hear!!!! I too have taken to scanning the top line of each message
and end up basically deleting them with the decision made in about .2
seconds. I used to read everything but there is just too much garbage to do
that anymore with my limited time. I do not favor moderation, but I do favor
responsible posting.

Hey Y'all...
My Sharp PC-3040 notebook has suffered psychedelic screen
death... likely cause being one too many episode of rough
handling.
Does anyone know of a source for these things?

Thanks for the acknowledgement, but I have to say that it was Louis's own
perseverance and hard work that got the machine going :-) No mean feat,
considering he didn't know much about logic circuits before he started, and
this machine actually had several faults!

Yes, though I don't think "interesting" was quite what we said while we

Now all we need are those modules :-)

I checked the pinouts -- the EPROMs do need to be TMS2532. Ordinary 2732
EPROMs won't do (the chip select and A11 address line are in the wrong
places).

If you get stuck, I can burn them for you, if you send me blanks.
