Anyone have a copy of the RK611 Technical Manual (EK-RK611-TM-001 is the
version that's attested)? It's not online.
(I have a copy in my fiche set, but my fiche reader died - no, it's not
the bulb, already changed that! :-)

32-bit code _should_ run on 64-bit Win7/8.x/10. 16-bit code won't.
Win7 has "XP Mode", which is a free downl

I did try reading it as an 8749. By 'not readable' I meant it re

But there is some kind of bug that always appears at the same point, in the

The data transfer stops (no more head motion/ready light flicker on the

is that true for "HC" parts or just NMOS?
And even more bizarrely... it crawled its way up to the 7400K block, and now
it's going at normal speed again! 10MB should be done soon.
I have no idea what could be causing this major slowdown from 6.6-7.4 MB.
It's not the drive because two different ones do the same thing (and they

The keyboard controller is an 8049. Firmware not readable.
It may actually be compatible with the 955 keyboard, which I was able to read.
Key layout is the same, though the manuf is different
OK, I have figured out how to modify TSGEN.MAC, use PUTR to make a disk
image, load it in SIMH, reassemble, relink, and *finally* send it to an RL02
pack via vtserver!
TIme-consuming but doable. I've been wrestling with this all day.
BUT - TSX+ 6.50 just will not run. At all.

It sounds like you are looking for an Ultrix 3.0 standalone boot tape. While
I found a number of people who claim to have a physical tape, with some
claiming to have imaged the tape, I was unable to find an image on-line. That
being said, it’s possible to use the Ultrix 2.0 standalone
