Okay, how about 2.3.2?  Do drivers for the short ARCHIVE controller board
come with release?  Or do I have to specifically request them?  When I ran
"mkdev tape" I specified a type "A" controller, Interrupt vector 5, and
base address of 0x200.  This works with devices /dev/rct0 and /dev/rct2
which apparently have different formats.  They both seem to have a capacity
of ~10 MBytes on a 600 ft tape.  I have the short controller board and model
60 drive.  It is supposed to store 60 MB on this length tape.  Well, I went
ahead and ordered the new release so I will see if it is any better, besides
it will be nice to get HDB uucp with the 'e' protocol anyway.  That way I
can take advantage of my 9600 baud MNP6 modem with my uucp neighbors.  BTW,
the machine in question runs at 16 Mhz and the fastape programs seem to work
with DOS.

Also, as if this wasn't enough rambling, I am hoping that 2.3.2 will cure a
bug with installing a Wyse WY-995 multiport serial card.  When it's
driver is linked with the kernal, upon booting I will get a message from
running "logger /dev/error /usr/adm/messages" in /etc/rc something like:
logger: read error - bad device.  Oh well, my machine never has errors
anyhow. :-)
