PDP-8 Disk Drive question

[Joe R.]

   Does anyone know if the M8357 (the RX-01 controller for the PDP-8) will
work with the DSD-440 drives?  Someone here needs to read some RX-01 disks
on a PDP-8 >>>ASAP<<< and they think that this combination will work but I
don't think so. I have a good DSD-440 drive system but I don't have the DSD
controller for the PDP-8. I also have a M8357 but no RX-01 drive system!
Anybody have a DSD controller for the PDP-8 that they want to sell or do
some horse trading for?
