[mod.computers.vax] 780 memory upgrade

anderer%vax1.acs.udel.edu@LOUIE.UDEL.EDU (ANDERER) (12/10/85)

I've got a 780 with an old memory controller, and 4 Mb of 16K memory (2 Mb DEC,
2 Mb NSC.)

I want to go to 8 Mb, either by adding another old controller and more
16K memory (ugh), or swapping our controller and memory for 64K equivalents.

DEC will do the swap for $46K.  Can any of the 2nd source memory suppliers
also do the controller swap?  Do they take trade-ins?

I've got the same configuration as you (4 MB, 16K DRAM's), except all my 
memory is DEC.  I, too, want to upgrade to 8MB.

I got a price of approximately $20.5K from Nat. Semi.  That was 256K chips with
a new MS780E, card cage, backplane, and controller.  They claim that all this
is DEC stuff.  Oh yeah, the $20.5K included a small credit for the trade-in.
