Gilderfluke&Co old MACs 8 bit Digital Audio System - Manual (Page 86)

Configuration and Installation:
Each MX- Repeater card plugs into J-5 (2 x 17 pin header) and J-4 (1 x 24 pin header) on the card
below. They are mounted by four 6-32 standoffs from the card below.
The Repeater card to which the first MX- card is attached must have four 6-32 x 1/2" hex standoffs
attached to it. In the case of DR- cards, four standard hex standoffs are mounted to the card using 6-32
x 1/4" round head machine screws. With AB-100 AudioBricks, the standoffs are 6-32 x 1/2" male/female
spacers which replace the screws which normally mount the card into the case.
MX- cards beyond the first one all mount using 6-32 x 7/16" male/female spacers (or a 6-32 x 3/8Ó
male/female spacer with a 1/16Ó thick nylon washer under it) to the MX- card below them. The last card
in the series is fastened down with four 6-32 x 1/4" round head machine screws.
The MX-100 cards are all configured as either 'EVEN' or 'ODD' cards. The first card on top of the
Repeater is always an 'EVEN' one. The cards are always configured as follows:
FIRST MX- MEMORY EXPANSION = EVEN
SECOND MX- MEMORY EXPANSION = ODD
THIRD MX- MEMORY EXPANSION = EVEN
FOURTH MX- MEMORY EXPANSION = ODD
FIFTH MX- MEMORY EXPANSION = EVEN
SIXTH MX- MEMORY EXPANSION = ODD
SEVENTH MX- MEMORY EXPANSION = EVEN
All MX-200 cards are factory configured as EVEN card, since they are normally mounted in the first,
third, fifth, or seventh MX- positions.
To configure an MX-100 card, two jumpers are moved to the positions shown below, and one of the
pins on the J-4 connection is bent downward slightly so that this one pin doesn't plug into any additional
MX- card which is mounted on top of it. If the configuration of the MX- cards is to be made permanent,
these pins can be cut off instead of merely bent.
