Don, I'd almost rather you hadn't said that. Were you deliberately trying
to raise false hopes?
I am going to have a long look through the documentation I have - including
several years' back issues of Tekniques, the 4050 series newsletter, and
see what I can find out. Meanwhile, if you remember _anything_, PLEASE
TELL US!

Hello, group. Especially you big iron folks.....
Going through several piles of surplus stuff at the shop where I keep my
workbench, I came across a couple of AS/400 things. One is a tape, still
sealed, labeled "System Program V3. 5763 -- PT1 and other programs." The
other is a book, still sealed, titled "IBM AS/400 Redbooks Collection Kit, April
1997"
If interested, email me off-list. Thank you for your time. We now return you to
the classic comp list, already in progress.

lucky dog! the //c+ is a nice machine and is the only // series model i am
missing now. you'll only be able to run prodos on 3.5 although you can always
plug in an external 5.25 and use that. nibble magazine used to sell dos 3.3
that was patched to run on 3.5 drives. it split each 800k disk into 2 400k
volumes. i dont remember what they called it; have to look in my old
magazines. there are two places on the net that are called 'ground' and
'asimov' that i've been told are some pretty good repositories of just about
any apple // program. someone will be able to post the URLs, i'm sure.

The 802 is the integrated computer/terminal unit. Call it a super-smart
terminal if you like, but it is a relatively convenient version of what
wasn't available much of the time back when these were current (early
'80's). It is not merely a terminal, though it will fill that function
nicely.

Does anyone know of any early (pre-1990) computers, other than the early
Toshibas, that used the parallel port to access an external floppy drive
(or other external storage device)? Thanks!
What you want is an Intergraph InterPro. Stay away from the InterVue (huge
cabinetry, with motors for the monitor platform and digitizing surface,
etc) and InterActs. (I have an InterPro 2000, dual screen machine).
The first InterPro was actually based on National 32000 chips. But after
that, they were all Clippers. Intergraph ended up bying the Clipper part
of the business from Fairchild, then a few years later went NT/Intel.
An InterPro 2000, 2020, etc. would do nicely. Although many were dual
screen, you can actually operate them with just one screen (and it might be
possible to disable the 2nd screen hardware -- I have never tried that with
mine though).
Wisconsin DOT has been unloading quite a few of these of late, and they
show up at the U. Wisconsin "SWAP" sale (every Friday -- they moved
recently to the East side of Madison, WI) occasionally from that source. I
paid about $50 for mine (but got a PS/2 server loaded with SCSI drives as
part of the big box of stuff I got).
Their Unix operating system, CLIX, was largely System V based, with TCP/IP
networking from Lachmann and Assosciates.
Intergraph recently released Y2K software for the beasties.
Best of luck.

I have just gotten 5 copies of IBM Disk Operating System Version 3.30
with 2-5.25" 360k and 1-3.5" 720k disks included. These are like brand
new, never opened. Asking $6.50 per unit, plus $5 priority mailing in
the lower 48 US states. AK and HI as well as APO/FPO may be more, will
have to see on a case by case basis. First come, first served. Money
orders only, please! I bought the box of 6 sets to get one copy for
myself at $40.00 and $6.50 is about what each copy cost me, so I won't
make any money at all on this. I know there are those that would love to
have this for that classic, or to have with other verions of DOS.
These are the small format manuals, not the encased notebooks so you
don't have to worry about pages getting torn out later.
I have calculated shipping from me to California, Chicago, NYC and Tampa
to come up with a rate that is within a few cents of actual, hence the
$5.00 shipping. All of the locations yielded a $5.40 priority mailing
and regular rate is real close to that.
If you want a copy email me directly at RHBLAKE(a)BIGFOOT.COM so I can
give you a mailing address for payment. Not sure of my reputation? Many
of you have bought and traded with me on eBay and on the lists so my
reputation for delivering what I post preceeds me. I'm not doing this to
get rich, just to fulfill my own nasty habit and spread the wealth among
other with the same "disease".

I can't remember about DS and DS$, but these may use some formerly unused
page 0 locations.
I do recall though that the 8000 series used the former table screen line
status bytes (whether the first or second half of an 80-character line),
which was not needed when screen lines were 80 character anyway, for a lot
of things used in the new screen management routines. The Fat 40, however,
did need the screen line status bytes, and stuck the screen management junk
at the end of the 2nd cassette buffer. So Cassette #2 can only be used for
loading and saving programs on the fat 40. Other data gets corrupted.
Anyway, West should contain it all, so best of luck when you get your
copy...
Philip.
The following is one of the type of instruments I have serviced for many
years and it normally came with a PDP8 and many were upgraded to a PDP11
data system. If anyone is interested in details contact them directly to
find out more. With the info they have on their configuration I would be
able to give some help on details.

IIRC, the only 6800 instruction not present on the 4052/54/52A/54A was DAA
- decimal addition adjustment. Since the 6800 has no decimal subtraction
adjustment, it was pretty useless anyway.
The main difference is the 128K byte address space. Two bits in the
processor status register were used for the 17th address bit (most
significant) - one for instruction fetches (default 1) and one for data
load/store (default 0). Most of the additional instructions manipulated
these. Nice features included: if you changed the bit for the instruction
fetches, it didn't actually change until the next ALUOUT -> PC microcode
instruction, i.e. branch or jump.

Almost exactly. And it's not just separate odd and even ROMs - it has
separate odd and even address buses! These hardware features do speed it
up, though. The other main application of the 16 bit data path was that
2-byte instructions were fetched with a single memory cycle, and this
happens quite often. The odd/even address logic meant this could be done
at an odd or an even address and still work.
My guess is that the hardware guys put a lot of work into that
architecture, wanting to make it both nice and 16bit and like the 6800.
Unfortunately, this took rather a long time, so the software guys just
wrote a 6800 near-emulator in microcode so as to speed the software
migration process. But this is just a guess.
Philip.
