CD-ROM from SCO unlikely

	Are there any UNIBUS/Qbus controllers that can deal with QIC-150?

	I tried putting a Wangtek 5150ES on a Emulex UC08 and it didn't work
	at all.  The only 'QIC' format I've seen work (and which preserves
	record boundaries) is the TK25 (uses the DC600A tapes).  I can 
	make TK25 tapes.

	I can also make 6250bpi 9-track until the tapedrive wears out (at
	which point I'm unlikely to sink the rather high $$$ to repair/replace
	it - 4mm drives are a lot cheaper ;-)).

	You've me to thank for that ;-)

	I think a CD is a good way to go - it can be used as the 'baseline'.
	The updates to 2.11 are publically available via FTP at either
	FTP.IIPO.GTEGSC.COM or MOE.2BSD.COM.  Once a system is loaded from CD
	then only those patches later than the CD need to be retrieved and
	applied.

	Of course!  There will be .MAP files to assist those systems that
	need help with long filenames or deep directories.
