Re: Sider (Xebec/Datamac SASI) drive and UCSD Pascal 1.1 (Apple Pascal)

[msg <msg@cybertheque.org>]

Progress made; I can now access the Sider volumes from a floppy-booted
system.  I found that 'disk4' contained the drivers as purged files
and after recovering those and copying 'SYSTEM.ATTACH',
'ATTACH.DRIVERS',
and 'ATTACH.DATA' to the boot floppy (there are versions for 1.1, 1.2
and
1.3), the hard disk volumes are on-line.

Still, these were absent (purhaps purged?) from our working original
system.

As a test I will purge these files from the working boot floppy and
see what happens.
