Well, if you really are running RSTS-11 V04A (which is how it was numbered way back then) you are running circa 1972 software. What kind of PDP-11 is the Systime system? RSTS Version 4 pre-dated memory management support (it was added in version 5). If your PDP-11 has memory management, you'll need to update to a more recent version (the current version of RSTS is V9.1, by the way). I don't know about your serial I/O card; for RSTS to support it, it will have to emulate some kind of DEC interface. Perhaps it is one of these things like 4 DL-11 interfaces on a single board. The same thing is true of your disk drive situation; I'd need to know what they looked like. Generally, third party disk drives emulate DEC drives with changes in disk geometry. These geometry changes are made by patching standard disk drivers. Assuming that you have memory management (if not, you're stuck at Version 4), you could update to RSTS/E V9.1 and get MACRO and the LINKer. Versions of RSTS prior to Version 6 didn't have any way to use MACRO on-line. Kevin Herbert Digital Equipment Corp.
