[mod.computers.vax] RA81's for MicroVAX-II

The reason the KDA50 is not offered in the BA123 box is because the 
bulkheads won't mount and still keep the box FCC certified.  Also, the 
KDA50 is a power pig.  Typically, by the time you get options stuffed 
into a BA123, you will run out of power.

I felt it was unreasonable to pay the xtra $10,000 for the H cabinet, 
so... I threatened to buy a 3rd party controller and disk subsystem for 
my MicroVAX systems.  The DEC salesman seeing $60,000 worth of disk 
leaving his booking sheets "caused" an allowance to appear and provided 
me a quote for a BA123 system with a KDA50.  The FCC certification is 
not a concern for our application...

The KDA50 is still not a very desirable controller.  And, lets face it, 
the RA81's are about as reliable as, well, never mind.  The other MicroVAX 
systems I've ordered have U.S. Design VIP disk subsystems.  They use MAXTOR 
5 1/4" winchesters in a BA23 box with a 512KB cache.  They are a LOT 
faster than RA disks...
