The console RX02 on the 780 wasn't "visible" to VMS. You'd need. MC SYSGEN CONNECT CONSOLE to make that happen. I used a PDP-11/40 with RX02's but never actually seen such an interface on a VAX unibus. Very useful to transfer data between systems; this was before ethernet was common, let alone affordable. An alternative was the RL02. Which became the load device for the PDP-11/23 console in the 8600/8650. I can't remember whether the RK05 was supported by VMS?

Verzonden: 23 augustus 2011 19:27 Correct, an RX02 floppy with a formatted capacity of 512 kB IIRC. Absolutely, on the 11/03 CFE. And any of the UNIBUS VAXen (730, 750, 780, etc) would directly support an RX01/02 on an RX211 interface. Such combinations were not unusual and were supported by VMS. I've got a 11/730 with an RX02 drive in the garage. Likewise any of the BI bus VAXen with a UBA could at least in theory do the same, though by that time 8" floppies were uncommon.
