  Can anyone explain the reason why Apple put the Aux
slot directly in 
 line with slot 3 on the European version of the IIe? For example, I 
 have a full length Ramworks III board in the Aux slot and this 
 completely obscures slot 3 so an accelerator so Sam's trick with the 
 Transwarp will not work. 
THe AUX slot _is_ slot #3. just some different signals. For
any 'regular' use you can only use the slot #3 connector or
AUX connector. The Transwarp is just (like some other very
special cards) desigend for uste in #3 while AUX is hosting
the 'regular' card. In fact, any card, able to run in slot
#0 (using no slot resources like RAM and (E)PROM space) will
coexist in #3 with a card in AUX.

The location was choosed to avoid that owners will plug in
two cards using the slot resources into AUX and #3, since
this (may) result in address conflicts. A far better solution
than any message in a manual for the usual I-am-an-expert-I-
-never-read-manuals user.
