    I have had success with the 2090 with another tape drive doing
multi reads and writes. My hddisk.device came from the 2090A diskette 
which is the latest version I could find for the 2090. I had nothing but
problems until I got hold of this.

    The tape drive I'm trying to run now does a lot of what Larry is describing.
My suspicion is the tape drive, since this has worked for me before.

    What tape drive are you using Larry?
