I managed to pick up a Mac Quadra 840AV yesterday with an apple VGA monitor and Laser Writer II printer for $60 CAD (approximately $5 USD :-) off the local classifieds site. The pram battery had leaked pretty badly but seemed to only drip onto the internal RF shielding. After I cleaned everything up with isopropanol it booted fine off a startup floppy although the hard disk appears to be bad. Like most macs of this vintage it does seem to have leaking surface mount caps so I am going to order the standard tantalum replacements from digikey and recap the mainboard.
What is everyone doing for replacement 50 pin SCSI drives in their 90's hardware? Is there a reasonably priced flash based replacement yet? I remember looking into it a few years ago for my Sun IPX and the only solutions I could find seemed to be priced for industrial applications.
Also, has anyone had experience with the apple power supplies of this vintage? I'm wondering if it's something I should recap as well? Also, any comments as to which classic mac OS version is best for this era of hardware? I haven't played around with classic macs much, I went right from the Apple IIe to PC's in the early 90's.
Does anyone know where and how one can obtain copies of Deth Specula's
work? It seems that all that's available is what I find at bandcamp.com
and some weird hiphop website, about six songs in all.

We have recently had activity on the list discussing AT&T 3b2 related stuff,
then earlier today we have had discussions concerning the SCSI2SD drive
I was reviewing the online documentation for SCSI2SD, specifically here:
and I specifically see that the AT&T 3B2/600 is supported.
Many years ago, when I was administering 3b2's, I had always remembered those
327 Mb drives were a PITA getting those replaced thru my supply system.
Wondering if anyone here is using SCSI2SD on their 3b2's, and if so, what are
your experiences? Hopefully working well?
I am in need of a set of rack mount rails for my pdp 11/34. I have a second
Cpu chassis that has been tying
up my desk since i picked it up. If anyone has these for sale or knows of
modern rails that will work i am interested. I do not expect modern rails
to do the flippy bit to work on the bottom of the machine, but it would be
a short term solution that will free up my desk.
I understand that, but isn't there something type of licensing built into the ssp software which is paired to a specific ssp?

Unlike the CS6400, the SSP can be any Sparc system with the packages
installed. The control boards for the E10Ks went over ethernet (JTAG
over ethernet in some cases.) Sun sold systems with everything from
Sparc 5s to Ultra 5s and Ultra10s as SSPs.
First thanks to all for considerable assistance.
I can now talk to the RX 211 on the Unibus.
First it did need the NPR jumper removing.
Secondly I made the system into an 11/84
(Processor in slot 1 nothing in 2 MSV11-J in 3 )
Finally I'm so used to hex modules in Unibus and the RX 211 is a quad.
Of course it needs to go in CDEF.
Switch on finds PMI memory ok counts up to 9 as normal.
Asks for choice. Type in B DY0 and we get a nice error message with lots
Time to become a 94 again.
Bonus: The other 94 chassis can become a 84 I have enough parts.
Just checking around if anyone has an E10K (or knows someone) that they
aren't all that fond of. I've been looking for one for the past year or
so but all the units i ever come across are missing SSP's. Pretty much
my only requirement is a working SSP, the rest i can sort through.
For people in the Bay Area
Ian Finder had mentioned a couple of weeks ago that Weird Stuff had gotten in some
MIPS systems. They put them out on the floor for $75 ea, so I got a RC3020, Magnum 3000
and Magnum 3000/33. Some had a full compliment of memory, some had some scsi disks in
them. Hopefully they'll haven't been wiped, since one machine had a MIPS asset tag.
There are still about 10 of them, mostly RS and RC 2030s
Curious thing is all of the machines, even the RC2030 have PS/2 connectors for the kb.
I tried to run the diskless controller test on my PDP8/A. It fails before
any tests has been executed. I suspect that my RL8A controller is broken.
The CPU tests and the memory tests works fine.
The test stopped @ address 5713 (display shows 5714), MD buff = 7402, AC = 0
Does anybody have the source code to this test? Earlier someone got the
test instructions photographed from microfishie.
The complete story is that the machine worked just fine, booted OS/8. Then
I changed the CPU from KK8A -> KK8E. The KK8E had some problems, but works
fine now. But now the machine doesn't boot OS/8 with any of the CPU's. The
diskless controller test stops at the same location with any CPU.
