Isn't that the
infamous computer that couldn't format disks? If not, what
was? I am not interested in acquiring this machine, but I would be interested
in the general specs
I have some old Byte 'zines that previewed the
Rainbow and one of
the reviewer's gripes (Jerry Pournelle ?) was that he had to run
around to find a shop that could format some disks. The controller
had it's own Z-80 board IIRC for duo floppies. It could use either
CPM or MSDos. I have 2 that I haven't ressurected yet ( no term, no
k-brd, no System disks, but one has a Seagate HD which I'm hoping is
self-booting ) I believe that this was another case of an OEM wanting
to lock in it's customers, so it failed miserably, altho there were
quite a few Rainbow user groups sponserred by DEC. Allison I'm sure,
has all the specs and there is a downloadable systems site.
Of all the machines that DEC sold with RX50 drives,
the Rainbow is the
only one that I own that *can* format blank floppies into RX50's.
Computers that couldn't format RX50 disks include:
Anything with a RQDX1, 2, or 3 controller (i.e. Q-bus machines)
or with a RUX50 (i.e. Unibus machines). Third-party Q-bus and Unibus
disk subsystems are generally capable of formatting RX50's.
*and*
Any of the DEC PRO series.
Actually, didn't some of the DECmates come with a RX50 floppy drive?
Were these capable of formatting?

Not being mini or DEC literate what is the RX50 format and what
systems (platforms) is it used on ?
