I have inherited a PDP11/84 with a single RL02 disk. When I attempt to boot the disk (using a pre-genned RSX distribution) I get an ERROR 20 - Controller Error. I have sent the controller out to DECMAILER, but the same error persists. I've also tried a second RL02 drive just in case - same error. The problem is that I do not have any hardware documentation at all. Does any one out there still have these beasts up and running? If so, could you please send me a more verbose statement of ERROR 20, or an
y other insights (other than scrap it!). The controller I have is marked M7762 (RLV11 I think).
