Macintosh IIci: Use Rev D.2 of NB-GPIB Card



National Instruments' NB-GPIB card is slot-dependent and needs to be
stationed in slot 3. The card works fine in a Macintosh IIcx, but on the
Macintosh IIci, the slot appears to be slot 6 to the application software.
Is there any way around this?

According to National Instruments, the NB-GPIB card is not slot-dependent
and works without any problem in the Macintosh IIci. However, an early
revision of this card (Rev D.1) had a compatibility problem with some
systems. The problem was with one noise logic chip on the card, the AS02
at card location U19. The Rev D.2 NB-GPIB cards have an LS02 at location
U19.

You can exchange the Rev D.1 card with National Instruments for a card
that have the LS02 installed. Or, you can upgrade a Rev D.1 NB-GPIB card
to Rev D.2, by changing the IC at U19 from the AS02 to an LS02. However,
users who change the chip will void the warranty on the NB-GPIB card.

Note: when running the NB-GPIB card test utility, the card may show a
failure, depending on the version of the software used. Below is a
listing of the software revisions.
