[HECnet] DECmate II and OS/278...

[Lee Gleason]

  Well, that simplifies things quite a bit all around. I'll write out a few 
and send them to you and see how it works out.

  What's your postal address?

Hi Lee,

I have a bunch of RX50 diskettes here that I can send to you.  However,
just to add more to this whole thing...apparently John Wilson has done
this before and has created a set of images that can be written from a
PDP-11.  The images can be found here:

     ftp://ftp.dbit.com/pub/pdp8/images/

This if from his README:

block   Contains RX50 images in PDP-11 block format.  These files can be
         copied to an RX50 drive on a PDP-11, MicroVAX, Pro-3xx etc.
         using COPY/FILE/DEV on RT-11, or some equivalent command on
         other operating systems.  The files are interleaved in the
         inverse of the method used by the RQDX1/2/3 or RUX50 firmware
         (or the Pro DZ: device drivers), so writing the floppy from a
         PDP-11 etc. will give the correct disk format (DECmates use
         their own different interleave scheme).  See block/README for
         information on writing disks using PUTR.

The images I'm interested in are:

   DM101b1
   DM101b2
   DM101b3
   DM1111
   DM1112
   DM1113
   DM1114
   DM1115
   DM1121
   DM122
   GAMES11
   GAMES20
   K12V10G1
   K12V10G2
   K12V10G3

That is  15 diskettes, so a little more than one or two :-)  However, as
I said, when I got the DECmate II it came with a bunch of diskettes, so
I can send quite a few along.

Regards, Tim.
