Make sure the CSR and vector of RLV12 is as described.
I'm not sure of the next step without powering my system and
at the moment I have two S100 crates in the way (testing).

Thanks to W. Donzelli's post, I just drove 4 hrs. (each way, 40-50
mph wind gusts!) to Little Rock AR and rescued the following
items:
DEC 11-40(?) open rack with two huge fans, an RL02 drive complete
with pack, a PDP-11/03-L and a PDP-11/24.
Both 11's appear to be complete and fully populated with cards (I
know something about 8's but very little about 11's). Sadly, all
the interface cables were cut/discarded during the salvage :(
Anyhow I've got way too many projects already (including my
PDP-8/A and currently nonworking RL02). I will probably keep the
11/03 for a "someday" project.
Is anyone interested in the PDP-11/24? Make me an offer. I'll sell
it reasonably priced to a good home. I can take some pics
tomorrow. It's *really* heavy though so shipping might be
expensive (from zip 65775). If no one here wants it, I'll put it
on the bay, since the donor explicitly told me he wouldn't mind if
I did. He just wanted to get it out of his garage...
thanks

That is by far the best method and also excellent for board you really
don't want to cook (as in ones you fix).
I've used that trick on PCs I wanted that had bad DALLAS DS1287
clock/cmos chips. Its easier then to sand off the epoxy to
access the dead battery for replacement.

I thought the 11/24 was the 11/23 chipset (F-11) mated to Unibus rather than
the Qbus.

A while back the Radio-Electronics series of articles on making your own 68000-based PC was mentioned as a possible scan candidate. Anybody know what direction that went? I'd be interested in seeing them- I have 2 of the issues but not the whole set (bit before my time)
On the same vein- I have a book called "Build your own Z-80 computer" by Steve Ciarcia. Is this the sort of thing that would have some interest in an e-version? Is there a fast way to scan bound materials without butchering them?
Hi,
I'm just wondering where you bought your SN76477 chip?
any info would be highly appreciated.i'm trying to
build a noise maker.
thanks!

It's in the queue after an 1802 and 8048 project.

Officially the bus load on the cpu is still high but past experience shows
it works. Intel would have you believe the bus drive of the chip is near
zero. Since I'd like to do IO I'll have to be aware of the bus load
as I go but I dont expect to have problems.
FYI: The clock circuit you used is almost exactly the one I did back
in '74. Intel rep said "it might work but its out of spec.". Compared
to the 4 one shots they show it was a vast improvement and lower parts
count. I tried the oneshot deal and vowed never to go there again.
Allison
I've seen several references to using torches to remove DIPs from PCBs. Are there any specific things to keep in mind to avoid heat damage &cet? Are you talking propane plumber's blowtorches?

I have an 8008 and HDSP2132 (8 char version). Wire wrap and a software
patch will have to do.
The 8008 appeard in one place thats common the 11/34 KY11 programmers pannel.
Possibly others.
I may not duplicate the design exact;y as you did it. Rather than memory
mapped I may implement IO ports. However looking at your design there
there some design simplifications that hadn't occured to me last 8008
project (1974). It's pretty cool and saves a carload of chips. Most
people back then were implementing multiple busses (address, ram data,
IO in, IO out, interrupt instuction) and thats a lot of chips. The MCS-8
is a really good example of getting carried away with multiple busses.
I hadn't looked at that chip in years and that was a different
perspective.
You could create a CPU, memory and IO card set.
