<div dir="ltr"><div>I had success booting the Unix Archive's floppy distribution of
Ultrix 1.0 on the MicroVAX 1 simulator. It appears that the
distribution there was only meant for a dual-RX50 MicroVAX 1 with an RD
drive, and will not boot on any other machine. RQ0 needs to be an RD51
or RD52, and RQ1 and RQ2 need to be RX50s. TTI and TTO need to be 7
bit. To boot the installer, put 32m-1.0-bin/01 on RQ1 and
32m-1.0-bin/02 on RQ2. The install goes cleanly, albeit with quite a
bit of disk swapping - the installation disk set is 13 floppies.<br>
<br></div><div>The QVSS is supported and will display some output on
boot. I haven't yet looked into what is needed to use it as the console
(if that's possible?).<br><br>The kernel seems to support what I assume
is the DEQNA - it has references to a qe device - but I can't figure
out how to get it recognized. Unfortunately there are no kernel config
files in the distribution, so I have no idea if the stock kernel is
expecting the controller at a non-standard address. Any help with this
would be greatly appreciated, <br>
