Trying to identify the S100 serial board in my Imsai 8080.

I assume it was a kit. There are wires from behind one of the ICs that go
to DB25 on the rear, along with other DB25s with a few pins (maybe
cassette input.)
Any help appreciated.

So, if one looks up the Cache Control Register in, say, the KDJ11-A
(EK-KDJ1A-UG-002), one sees (in section 1.6.2.1) that there are _three_ ways
to disable the cache: bits 2, 3 ('force miss'), and 9 ('bypass cache').
Looking at the DCJ11 manual (EK-DCJ11-UG-PRE) doesn't provide any additional
insight.
(The 9 bit one is slightly different than the other two, because it causes
cache contents to be invalidated as the code runs, whereas the other two
don't.)
What is going on here, does anyone know? I'm _guessing_ that this is for
compatability with the -11/70, where the cache is divided in two ('two-way set
associative'), and either half can be disabled separately (using the 2 and
3 bits in its CCR).
I suppose only someone who worked on the DCJ11 would know; but I have no idea
how to track down such a person.

hi
I am trying to build gcc v4.7 on a remote IRIX machine (not my
property, thus I can't access it 24h/7) with these (1) gnu-files,
patch, and scrips (you can see how things are configured for
compilation)
I am stopped at the ppl v0.11 stage with the following error that I am
not able to understand neither to solve
any hint?
thanks

(1) http://www.downthebunker.xyz/wonderland/chunk_of/stuff/public/retrocomputin…
Collected stuff for over 10 years. Moving from 2300 sq. ft. to 1400. It
had to go. Praise the computer gods I found someone that wanted it all.
115 boxes of manuals and documents.
26 boxes of coffee mugs
73 703 boxes of stuff.
106 loose big items.
Filled the floor space of a 26' truck.
It can be viewed at http://www.ibmjunkman.com/junk/
Best viewed on a PC with decent speed connection.
Sample stuff: 360 Mod 20 panel, mod 30 panel, mod 65 panel, s/3 panel. Disk
pack and HDA up the ying yang. 3850 data carts, 2321 data cell, 7340
Hypertape cartridge, a Russian equivalent, desktop chachki (tchotchke), 360
mod 70 desktop model used in 1964 World's Fair, etc, etc.
Someone working on simulating the scsi DIO board in MAME asked me about the scsi loopback
test plug. Anyone ever seen one? Is it just wires or are there active parts doing the loopback?

Yeah, I hate it when ebay gets creative. It usually ends up screwing the customers/buyers.?

ok, I'm guessing this is an SMS floppy controller
why is someone willing to pay $50+ for it in the condition its in?
So, it appears that the KDJ11 (definitely the -A, and probably all of them)
cannot execute code from the PARs - one gets a NXM trap. (Definitely the
kernel I PARs, I haven't checked all 6 sets, but I can't see why they others
would be any different.) Has anyone else run into this, so I can be sure I'm
not confused?
This is a mild pain, because it's nice to be able to put short 'scope loops in
them, either to debug a memory card when you don't have any working memory
plugged in, or when you don't want the bus 'contaminated' with instruction
fetch cycles, etc.
