been running a tw gs with 32/cache since 1990 continously...no
problems..at the 13.75 mhz range....i've found the oppisite...that the
zips gave me and some others problems...must depend on the
card...although i'd prob get a zip now in that they are more common
in case you blow up your accelerator..

whatever...

(anyone know how to stick dos 3.3 partion on a scsi hd.....i've only
seen the utils to do that on 800k disks..and the option on sider hd's
would like to avoid the sider hd purchase if possible and just get a
software pkg that will partion part of a scsi drive with a ramfast

(goal is to put up my original 1983 software..that way all my systems
will be up an connected 3 gs's serially connected doors of the major/wg
system i run now..people need that 2400 baud speed and asci downloads
with kermit don't ya know....)
