I got the remaining parts I needed from Steve today

I get as far as the LEDs on, but no sign of RS232 (on terminal or
breakout).  My terminal (at vt62(!)) can be picky about control lines,
so I've jumpered 5&8 to 20 (CD&CTS to DTR) on the breakout and all the
lights on the terminal seem normal. (CTS and Carrier lit).

Here is my setup;

2 2681's installed (first and last -- U48 and U60)
serial connector on CONN3 with a 3 wire cable:
	CONN3	DB25
	3	3
	5	2
	9	7
One RS232 driver in U47
4 1Mx9 SIMMs in U6,U8,U10,U12
No 280's installed, Parity PAL not installed
No FPU installed
20MHz osc on CPU (U25)
AIC6250 and DP8490 installed
J1 between 2&3
J2 between 2&3

I've made only 1 dubious substitution (74F00) but I can't imagine this
makes any difference running at 40% of full speed.

Voltages on the +12V and +5V rails measure 12.17V and 5.11V with my
cheap digital VOM (the only test equipment I own). No external loads
(disks) on 12V.

I see about 1mm clearance between the '532 and its socket.
