Many of the items on your form are implementation
rather than architecture, so you will need a separate
entry for each implementation.  Maybe you could
collect the architecture stuff at the front of the
form so we wouldn't have to repeat it.  For example
HP Precision architecture has several implementations:

Model		CPU	FPU	Cache	Bus
HP9000/825	1	1	1	1	
HP9000/835	1+	2	2	1
HP9000/840	2	3	3	1
HP9000/850	1	1 or 2	4	2	
HP9000/855	3	2	5	2

(And the equivalent HP3000 machines.  The difference is
HP9000 runs HP-UX and HP3000 run MPE).

There are 3 completely different CPU's (one with two versions),
3 different floating point coprocessors, 5 different caches
(different size and/or organization), and two different
busses (with 3 different memory systems).
