***The UI vax's were not functioning properly during the last of Jan. and
early Feb. so I am resubmitting as I have received no notes and assume it
never made successfully to the net. Forgive me if this note is a repeat on
your system.***

After years of faithful service, our trusty S-100 System gave up the ghost.
Actually the computer still works fine. Its the floppies that went. After
reviewing the situation, we have decided to use this system for backup
activities and transfer of 8" floppies to 5.25".

We have found the Morrow "Disk Jockey DMA Floppy Controller" which appears 
to meet our needs. Does anyone have experience with this controller which
allows you to use both 8 and 5.25 inch floppies?

The major question is what drives? We need 5.25 compatable with the Televideo
5.25 floppies. I have heard that Shugarts are the best! What do I need to look
out for which could cause a problem? Oh, yes we currently have CP/M 2.2.

much thanks, Carl E. DeLong 217-352-6511

A student in my class has the controller you mention and successfully
copied some files for me last semester.  He is very knowledgable about
the device.  I'll put him in touch with you. - Mike Faiman, 228 DCL
