Unfortunately I can't get past that solid-on diagnostic LED. I had
hoped that it might have been re-purposed in a later rev level :-)
Got all the ZRQ* binaries downloaded via simulated TU58 and they hang -
funnily enough the old-rev ZRQA that I have on floppy reports the
controller there and passes interrupt test before failing with 'no
drive'. I can also access the CSR using ODT. Not much more I can do
without more tech data so I guess I am still looking for an MFM controller!
I've been nursing a painful tooth infection so I might have missed
something!

Has info on ZQRC binaries and .bic / .bin images - loading is of course XFU.
The .bic image is (essentially) in absolute binary paper tape format, which may
or may not help with loading.
ZQRC has been extracted from the RL02 images which are up on BitSavers.
Enjoy

Subject: Looking for DEC XXDP TU58 images
I have recently acquired my first ever RQDX3 and put it in a BA23 cabled to an
RD53. Unfortunately the self-test light stays on, but I thought I would see how
it responds anyway. The only thing I have on the system that can boot is an
RX33 floppy and emulated TU58.
I have all of AK6DN's posted TU58 images, and found ZRCD, which is for the
RC25, and the controller passed the interrupt test, but then of course gets
errors since it is not an RC25.
I need ZRQC. Does anybody know where I might get a TU58 image with it on?
cheers,
Nigel
