An 8080 could not do it and graphics has little to do with it.
FPGA P&R is a really large array problem that eats memory and cpu.
The PC is a common choice as it's become fast enough and common
as houseflies. After PCs what s the next most common hardware?
A vendor of hardware (FPGAs) really only provides software so they
can sell the part, I doubt that software is a money maker for them.
So with that in minds if you not running a PC then likely the
alternate hardware is from the small list:
VAX or Alpha running UNIX
AS400?
Something PowerPC based?
SUN?
What else is out there that's not wintel, fast enough and can address
a large memory that runs a fairly current UNIX. That also assumes
the software that can P&R the FPGA is available as source.

I found one of the rom images I put up was a bad prom. Another one read
consistently but didn't match two other sources. The images have been
replaced. Affected images : 752A9, 248F1, 616F1. I replaced them after
getting multiple other images and comparing, so I'm confident the ones up
now are all correct.
I'd like to post source listings for the boot programs. Anyone got a program
to re-arrange the bits correctly, then disassemble?

RX01 drives and RX02 drives are the same. Only the logic differs.

Hello all,
For many reasons, which I don't care to detail, I'm getting out of the
"business" of vintage computing (In fact, I'm no longer subscribed, so don't
reply to the list, because I won't get it). 95% of my collection has been
sold, given away, or dumped, and I only have a few more items, plus the
components listed below.
I am offering these components to the best offer, plus shipping from MA, USA,
Zip Code 01473. I *strongly* prefer PayPal, but will take USPS Money Order
(*no other payment methods, please*).
These components have been stored cool and dry, but are untested. Also, many
of them have *not* been stored in anti-stat drawers, so please keep that in
mind. I will ship on anti-stat foam if posible, or wrapped in foil if I am
unable to put them in anti-stat foam. Vast majority of date codes are in the
late 70' to early 80's. I'm not sure what a lot of these even do, and I
don't have datasheets, so you're on your own identifying them :-)
I'll keep the bidding open until 10/31, midnight, my time.
If you are interested, please contact me *off-list*
(richard.beaudry at gmail.com) with offers, and let me know your ZIP or country,
so I can estimate shipping. I will let the final list of people know on 11/1
(or thereabouts) by email what they can get.
Part 2 will be listed in a week or two, when I finish cataloging it...

Works great with NS* hard sector controller at 300rpm.

QD is for those systems that DD was 360k (48tpi). QD system could be 720k,
780k(amproLB).

Or the common QD systems I have the data rate is same as DD (still 300rpm)
but there are twice as many tracks or quad. 5.25 floppies started at 80k
(sa400 single density one side 40 tracks (48tpi) all the way to near 800k
(FD55F, DD, two sides 96tpi). There were enough marketing names to the
capacity jumps to confuse even the marketers. however once the data rates
hit DD there were SSDD(160K raw), DSDD(400k raw) and then DSQD(800k raw)
and there was even a SSQD(400K raw) (yep 96tpi DD data rate and only one side).
that last one was know widely as RX50 and also appeared using FD55E on
Visual 1050. There was the 1.2mb PC thing.
This is why 5.25 floppy was so much confusion as it morphed from the 35 track
SA400 through the FD55GFR.
There there were the formats applied.. [open can, worms!, run!]

I was reminiscing to someone about an old GE mainframe with an analog meter
that registered Kops/sec. I'm sure it was little more than an RC
integrator hooked to the RNI signal reading out on a voltmeter, but it
seemed pretty spiffy at the time.
Has anyone done a similar thing with their vintage systems? On the 8080,
the M1 signal could be used; I'm not sure offhand about other processors.
I know--it's more simple amusement for a simple mind...but then, blinking
lights always fascinated me.
Cheers,
Chuck
A California bankruptcy court will sell Interex's membership database to the
highest bidder to help satisfy creditor demands of the bankrupt user group,
according to recently filed court papers. The Hewlett-Packard Co. user
group claimed about 100,000 members before filing in August for bankruptcy.

A 9133 is a hard disk/floppy disk combo drive - there's no CPU. The CPU
is in a separate box - probably something like a 9920, 9000/217,
9000/300, etc. Joe Rigdon is also a good bet for advice on this stuff.
