   BTW what
are the two extra jumpers on the later revision card? 
Which jumopers? 
 If you look straight down, with the handles at the top, the card with the
 23-243E5 and 23-244E5 ROMs has a pair of jumpers to to the right of the
 ROMs.  These aren't on the cards I've got with the 23-216E5 and 23-217E5
 ROMs, nor are they on the documentation that Bruce Lane provided last
 weekend. 
Hmmm... Not shown in my RQDX3 manual, nor on any of the microfiche I have.
 At first I thought you might mean W23 or W12/W13, but they're on the left.
 I suspect they're some factory test setting.  If I have the time, I'll
pull one of my RQDX3s this weekend and have a look -- though just looking
at them may not do much good, of course!

  The card with the later ROMs will in fact support my
home made RX33's. 
Sounds like all the jumpers (except possibly W23) are set up right, then
:-)
