Have the user / assembly manuals for the MicroAce (unlicensed Sinclair
ZX80 clone) been archived anywhere? I did a quick search and I didn't
find anything. If not, is anyone chomping at the bit to have it archived?
I just picked up an interesting set of hardware that I thought was a
Sinclair ZX80 plus an empty MicroAce case, but which turns out to be a
MicroAce Issue 1 PCB installed in a Z80 case (with ZX80 keyboard overlay
fitted, plus the 8K ROM upgrade overlay taped on top). Came in the
original MicroAce box with documentation, sales receipt and a photocopy
of "MicroAce / ZX80 Video Secrets Revealed!" (which I also don't see
archived anywhere)
If this isn't archived anywhere, I'll see what I can do to get this
scanned at some point.
Also -- as an aside, I'm faced with a dilemma: do I restore this thing
back to a MicroAce, or leave it as the frankenstein it is? I have the
original MicroAce overlay (never used -- still has the protective
backing on the sticky side) but it's pretty clear that whoever put this
together assembled it as a ZX80 from day one, for some reason. The
MicroAce is considerably more rare than the ZX80 (which is already
pretty uncommon)... but then again it works fine as is. (Really the
only irreversable step here would be peeling off the ZX80 overlay and
sticking the MicroAce one on.)

If anyone is making a trip from Chicagoland or nearby major cities, will
you please contact me off list. I'd like to see if we can make arrangements
for a joint shopping trip or purchase. Thanks in advance.

The DECbrouter I got recently has a little fan attached to the side. This
prevents me putting the DECbrouter into a DEChub because the fan assembly
fouls the metallic leaves on the DEChub. It seems that the DECbrouter is
designed to allow use with a DEChub, but in my case it won't fit.
Is there a different DEChub that does not have the metallic leaves at one
end of each slot?
How critical is the extra fan? The fan is pretty small and I could remove
the extra fan assembly.
Regards
Rob

@Mark: AFAIK at least two people from Chicagoland are either coming up or
have made arrangements; hope you can get together.

Hi Jerome, (haven't seen you in many years; how are ya!)
As Kevin himself said, it's quite a job inventorying his treasures and
staying on top of what's been taken and what's spoken for and by whom,
so be patient ;-)
I picked up a few items last week but will probably be going back for a few
more, so if you make arrangements with Kevin for anything I'd be happy to
pick it up and bring it back for you if it's not too large (but then you'd
miss the tour ;-)

I decided to take my life and my capacitors in my hands and try to
power on the somewhat grubby old Mac+ I was given recently.
I hooked up a keyboard and mouse and plugged it in.
The floppy drive makes a very short whine, the Mac emits a fairly
basic monophonic happy-Mac beep, and sits there humming quietly at me.
However, the screen does not light up.
It /sounds/ like the logic board is initialising OK but the screen isn't.
Is there much troubleshooting that someone fairly electronically
incompetent can do to one of these?

Hi
I'm looking for a way to rackmount my BA23 (and BA11) boxes in my H960
rack. Most modern solutions is rather unsatisfactory (some doesn't fit,
others are crazy expensive).
So, does anyone have a stack of these:

Hopefully in Europe, but shipping from USA might be worth it. I need
about six pairs.
Regards,
Pontus.
I don't know this company, but I came across this page, and it is the
cheapest I have ever seen for this old memory!

Hi,
I recently aquired an old Netcom system and I'd like to find out a bit more info about this backplane.
It's an 11/23 system (based on CPU) . It has some standard DEC
cards in it (M8186 CPU, DLV11, BDV11 bootstrap board ) as well as a thrid party 256Kb memory board and an MXV22 floppy controller.
Apparently the system ran RT-11 from floppies a few years back before it was put in storage.
I have read through the PUPS archives, esp. a post from Michael Sokolov back in 98, where he describes
the different types of QBus'es. Q/Q, Q/CD etc. Have also read through the info on hampage.hu and various other sites that host PDP11 related info,
but am still unsure about this particular beast.
It looks like the backplane that I have (according to the archives and some documents written at SLAC in late 70's)
is a serpentine or sinusoidal type configuration. The SLAC documents actually refer to the Netcom backplane but they
describe it a simple serpentine type.
A diagram on my cardcage describes it as follows:
A B C D
------------>
<-----------
------------->
<------------
There is also a blurb about slot 2/CD being wired differently. Two slots on the diagram are pre-printed for RL controllers. I can't rembeber the exact wording, since I don't have the computer in front of me.
It gather that I insert the CPU in 1AB, then rather than putting the next card in 2AB, I would place it in 1CD. Next would be 2CD and so on ,snaking down the line. Is this correct? While this is all fine for dual cards, but how does this configuration
handle quad cards? I'm guessing that it has to do something with that 'blurb', but that would mean that I can only have one quad card installed, and it would be right towards the begining of the bus. The BDV11 should
be the last card in the chain from what I can remember.
Also, my CPU card is a rev. D so it can do 22bit addressing. I'd like (if possible) to run 22bits, since this would allow
me at a later time to put in a 11/73 cpu that would give me more flexibility in what OS's i can install on the machine.
I'll have to check if the backplane is wired for 22bits or not. I seem to remeber the standard qbuses had the W1-W4 pins (?)
that you could wirewrap to change from 18to22 (i'm assuming that this operation propagated the BDAL17-20 from slot 1 to the other slots) but this backplane has nothing like that.
I'm planning on checking it with an ohmmeter, and it should be very obvious if these signals are present across slots.
The backplane is a PCB style, but it does have std. wire wrap pins sticking out from the PCB. If the BDAL17-20's are not present across slots, can I just simply extend them thru by wirewrapping?
If anyone can shed any light on this backplane, it would be greatly appreciated.
thanks in advance for any replies.

All,
Following the recent trend of repentant hoarders, it's time for me to slim the herd. In particular I need to recover the use of my second bedroom. So I need to find happy homes for the following:
IBM System/36 5362 (US Model)
IBM System/36 5363
IBM AS/400 9404 (CISC)
IBM RS/6000 7025-F40
IBM RS/6000 7015-98B
IBM RS/6000 7015-999
IBM RS/6000 43p (several)
HP Apollo 9000 Model 400 (68040 upgrade)
I may also have a number of smaller Sun, HP and IBM UNIX boxer available. None of these machines have been run for between 10-15 years. They may require attention, which since I've not touched them in quite some time. Better they go to you, eh? These would all be for pickup in the from post code GU51 2UD. I'm not looking for any financial exchange, but I would direct you to donate generously to The National Museum of Computing (www.tnmoc.org).
Regards,
Colin
