board, you will probably have to get a PC ISA-8 ("PC XT") Slot board (or an ISA-
8/16 Slot board with the extra contacts trimmed off).
An ISA-8 board has 31 contacts per side spaced the same as an A2 card. From
the edge facing the front of the computer, you will need to count down and trim
away 6 contacts (per side). It's best to use a real A2 board as a guide to
determine pin centering and to decide what to slice off for a good fit in an
Apple II Slot. A Dremel tool with a sand wheel is good for this sort of slicing.
The best deal I've found on proto boards for Apple II Slot card projects is
the 9003 PB from Marlin P. Jones (still offered as of Feb 2004). It's a good
length for most applications (5.6") and costs $7.95. The 9003 PB is 4.25" high;
so, you will need to cut off about 1.5" from the top to get a fit in most Apple
II's.
Another approach to getting an A2 prototype board is to 'clean off' and
reuse a surplus A2 card. Or, you can slice off the connector pins (plus a bit
extra) from some surplus A2 or ISA-8 PC board and bolt the connector to a common
rectangular proto board.
