rl02 Initial tests

First thing is to run some tests. I used the Unibone test setup. As most Unibone xxdp scripts actually use an emulated RL02 I had to use another thing to boot from. I chose to use the rx02 emulation, and one of the rx02 images from here. More details see here.

The results of the 1st run:

Apparently this is error 300 of subtest 025 at pc=015454. Looking up the fiche in the fiche database on retrocmp.com:

From that we learn that we have a “composite error”, and “OPI” is set. OPI means:

The failing test is test#25. That reads as follows:

Second try

I found out that something was off with supplying power to the RL11 controller so I fixed that and restarted the tests with a drive running. This resulted in:

Looking at test 27:

This seems to be the first test that actually talks with the disk drive- and it is not answering..
