RX02 rx-01 heathkit 8 inch drive for H-11 ( lsi11 heath case drive diff?)

Rich -   correct. That is the  disc  we have  here.
Just  wondering in case  We ever  got a pdp-8 with   disc  interface or a 
standard  unibus  PDP 11 here at  SMECC  .   We  have an  11/20 but of  
course not much memory  and no  disc  controller  so it  sits.

Are you  referring to having the H-27 drive from Heath? I don't know for 
sure because  I've never seen H27 docs, but the disk capacity is the same as 
the RX01 (256k)  and I think the interface was made deliberately 
incompatible, likely at the  behest of DEC. The version of RT-11 (called HT-11) 
supposedly used a different  floppy device driver. 

Again, this is based solely on what I've read  from various places and not 
direct experience (I have an H-11 with a SCSI  controller; no floppy; and it 
runs RT-11 no problem).
