You’’ll need to create a bootable RX50 (or emulated TU58) image. There are several RX02 diagnostics programs and ZRXF (NRXFAO) excercises RXV21. Others test the Drives. Jerry

In general, the recommended order on microPDP-11s is: memory Ethernet and/or synchronous comms, eg DEQNA, DPV11, DRV11 printers, eg LPV11 other serial comms, eg DLV11, DZV11, DHV11 tapes, eg TK50, TK70 disks, eg RLV11 MSCP Hi Pete I put the memory then the cpu then the RXV21 and finally the RQDX3. System boots from the RX50 and the RD53 just fine. Now I need to run diagnostics on the RXV21 and then the RX02. As usual the manual tells you everything you dont need to know, I thought L RXDIAG then CR and S but no the prog. was not on yhe disk. Suggestions on testing RXV21 please Rod \
