O.T. Digital RX02 Floppy Drive

These days I use Siemens S7-400 PLC's for process control (PID)
but in the late 70's early 80's I used Digital PDP11 computers
running what can be described as a PLC operating system. Well,
believe it or not of the 20+ PDP11's about 5 are still running.
Most now have Citect SCADA sitting on top and look quite up-to-date.
Anyway, the problem now is the RX02 dual 8 inch floppy drives are
becoming very hard to support and the customer has already
cannibalised all the other PDP11 systems.
Eventually I would like to replace these systems with PLC's but
in the meantime the customer wants to find a way to live with or
replace the RX02 Floppy drives. Ideas that come to mind.

1. Buy used preferably refurbished RX02 drives.
2. I believe somebody was developing a solid state RX02
compatible module using RAM or similar memory.
3. Somehow be able to download the PDP11 program from a P.C.
4. Scrap the PDP11 computer but retain its excellant IPV11 I/O
system (D-Bus) and interface it as PLC remote I/O.

I am hoping somebody has a solution to this problem.

A pdp11? I haven't seen one of those in 20 years, a friend of mines father had two in his basement! Now that is a testament to quality manufacturing

RX02 compatible disk drive

I have been continuing my search of the internet but cannot find
my preferred option although I am sure somebody has done it.

That is an all solid state or using a modern hard disk plug and
software compatible RX02 drive.

I will continue searching.

DEC RX02 Dual Diskette Drive

I guess the ideal would be a complete plug compatible unit using
a pair of modern plug in memory cards in place of the 8 inch
floppy discs.
