[net.periphs] Wanted: experiences with 7.5 Mbyte DSD880 disks

mario (04/08/83)

Several years ago, we undertook a workstation project using the LSI 11/23 CPU
(in the form of the VT103) and using the 7.5 Mbyte DSD880 winchester disk +
floppy.  We purchased a number of these units, and have been trying to make
Version 7 Unix(tm) run *reliably* on them ever since.  While Unix runs
reasonably well (the performance is comparable to an RL01 based 11/23 system),
a large number of problems have occurred with the DSD880.  The disks tend to
lock up without explanation, there have been a large number of file system
problems, and, in general, getting software to run reliably has been
frustrating.

I would like to hear from anyone else who has had any experiences with the
7.5 Mbyte version of the DSD880 with any flavour of Unix.  As this information
is likely to be of only very specific interest, please reply directly to me by
mail at ...!decvax!utzoo!utcsstat!mario.  I will forward a copy of the
information received to anyone who requests one, and to the net if the
number of requests warrants it.

Thanks in advance,
