PDP-11/93 - the 20th anniversary PDP-11 the last PDP-11 made by digital (Digital Equipment Corporation) My PDP-11/93Thanks to Doc Shipley for trading parts and providing advice, and Johnny Bilquist for advice and guidance in configuring the BA23 system chassis.
Remaining components needed (mostly cosmetic):

QBUS backplane configurationA surprise I found with this system was the number of microprocessors employed in the implementation of various controllers.Here is a list of uP found in this system:
PDP-11/93 performance comparisonComprehensive listing of relative performance of PDP-11, VAX and Alpha machines from Pete Sivia. PDP-11/93 has a VUP "VAX 11/780 Unit of Power" of 1.0 The following is a VUP and SPECfp92 table that I put together a while back using a number of different public sources. As a bonus you get some PDP-11 ratings courtesy of a chart that showed up a few years ago in a DECdirect catalog :-) DSNlink also has an article called "CPU types and their related VUP Ratings" dated 15-Jul-94 for those who have access. (Note: the SPECfp92 ratings for Alphas have undergone change since the models were first introduced as various pieces of the operating system and microcode were "tweaked". The numbers appear fairly stable.)
