Carlos,
That NI GP-IB card may not be GP-IB! I have a NI NuBus card with what
looks like a HP_IB connector but I couldn't find it on NI's site so I
E-mailed them and asked about it. It turns out that it isn't GP-IB but some
kind of data aquision card. I don't remember the model number but it's
around here somewhere.

I found a nice Mac II yesterday with Natl. Instruments HPIB,
20MB memory, Asante NIC, and framebuffer. What makes it
special is that it has a Daystar accelerator that plugs
in the 68020 and MMU sockets; the accelerator
has a 68040 @ 33Mhz. I had not planned to keep any NuBus
machine (I'm tossing stuff out due to an impending long trip),
but, since I have the Natl. Instruments software for the
HPIB card, and some other interesting Nubus DSP cards,
I am tempted to keep it... so I thought I'd ask some questions
to help me make up my mind.
Does anybody know more about this accelerator? What kind of
performance does it yield compared to, say, one of the later
Quadras? Are there basic differences in the I/O and bus
architecture that will prevent the 68040 from reaching its
full potential on a Mac II mainboard as opposed to a 68040
in a Quadra? Do Quadras have faster SCSI?
Also, the machine has two floppy drives; how do the Mac II
drives rank among those found in Apple machines in terms of
usefulness/durability?
Thanks for your suggestions,
Carlos.
