Subject: Looking for a Heathkit H-8 LED Display Cover
I picked up a Heathkit H-8 the other day, well... I won an eBay auction but
I got it for a good price. It looks to be in good condition and is full of
cards but it is missing the red LED display cover. Does anyone know where I
might find one? Also, are there any H-8 manuals out on the web? It would
be nice to check this thing out a bit before I fire it up. My H-11 manuals
were not much help.
Thanks,
Nick Miller

Nick,
Seeing as you mentioned your H-11 manuals... I have an H-11 I'm trying to
bring back to life. Is there any way I could borrow (or have you copy) your
H-11 Operation manual. I have every H-11 manual except that one! I have
H-11 Assembly, Serial, Parallel, H-27, etc. just not the H-11 operation.
I've checked the PS (end of H-11 assembly), and everything *should be* fine,
but no workee! I'm not sure where the problem lies.
If you're unwilling to lend/copy the manual, could we spend some time
e-mailing each other about various steps for checkout?
Thanks,
Gary
(PS, I'm in Fort Wayne, Indiana if that matters any.)

Speaking of DIBOL, I need COS-300 for some of my 11/23s... In case you
didn't know, COS-300 is RT-11 with DIBOL layered on it or something..
COS-500 is the same but its RSTS-based if I remember correctly..

Thanks for jogging my memory on this, I've been carrying the manual
around for a couple of days.
Looks like the 12699H, 12746H, 12747H, and 12749H boards each have
a set of switches or jumpers labelled with some subset of letters
A through H, and how these are set selects the base address of the board.
Jumper in or switch closed is a logical 0 and jumper out or switch open
is a logical 1.
A is 0x004000
B is 0x008000
C is 0x010000
D is 0x020000
E is 0x040000
F is 0x080000
G is 0x100000
H is 0x200000
Some boards have some of the jumpers/switches hard wired, others require you
to set them certain ways. E.g. 12746H needs A out, G out, H in and 12749H
claims that A, B, C, D, G, and H are all hardwired out.
All boards appear as a single chunk of memory, so a 12749H board with 256KW
can only appear at 0x000000-0x03ffff, 0x040000-0x07ffff, 0x080000-0x0bffff,
or 0x0c0000-0x0fffff (these are the four 256KW chunks from 0 to 1024KW).
Most boards appear to be limited to appearing below 1024KW. The 12746H
appears to be limited to appearing below 512KW.

I have a Commodore SX-64 for sale. This is the semi-portable Commodore
64 with the built-in monitor. I think they are rather rare.

Jim,
I stumbled on www.classiccmp.org and noticed your reply to William Donzelli's
post (yesterday):

Is the FPU you're looking for the 68882? If so, I think I have one. I don't
know what package types this was offered in, my vague recollection is that the
one I have is about 1.5" square pin-grid array. Anyway, you're welcome to it
if you're interested.
In return (or in spite of this!) I have only one request: the FAQ link for the
Classic Computing message board doesn't seem to work for me - I need it
because I want to offer the rest of my old Apple hardware up for grabs, but I
don't want to spam the list with things like:
"I have a complete Apple][+ system with a fair number of expansion cards and
Sider 10MB HD. The remainder of what I have is old Mac-era stuff, I think I
have had to throw out all of my one-piece hardware (Pluses and SEs) but I have
a complete Mac IIci, possibly a IIsi, and some PM6100 and Centris 610 form
factor stuff that wants a home."
Perhaps there is a subset of folks that are interested in providing a home to
more old hardware? I'm located just north of Boston MA.
All the best,
Arthur
