DEC RX01 Parts

Thank you.  That is what I figured.  Now all I need is a RK8E or RX28 
controller and I'm all set.

I'm becoming more and more tempted to have some of Roland's TTL version 
boards made and build one up myself.

I am trying to get an 8" shugart type drive and using the GreaseWeazel I 
will be able to format disks for RX01.

The author of the original firmware is working with me to modify the 
firmware for the screwy RX02 format.

The nice thing about the RX01 drive set that I have is that I can just 
flip a dip switch and have an RX02 instead (as long as I install the 
appropriate RX02 OS/8 driver and have the RX28 controller card).

Thanks again,
