Resound /2 OPL3 MCA
"Please note, this card will not playback WAV/digital files,
it is an FM synthesis card only. The OPL3 is the sole
provider of sound."
Missing Audio Sum Pins
[B01 and B02]
This version seems to lack the MCA contacts B01 and B02
(Audio Ground and Audio]. This is NOT a problem -UNLESS- you
want to use the internal speaker.
This is NOT a defect. If you are using headphones or
external speakers you won't notice it.
MCA Bus Interface P82C611 vs CPLD
"This card uses the P82C611 bus interface chip and will not
work with faster MCA systems. For a more widely-compatible
version, use the Plaid Bib CPLD version."
Note: The P82C611 does
not use DMA.
YM3812 vs YMF262
"The YM3812 FM synthesis chip has minimum timings that are
somewhat too slow. For example, the read pulse width minimum
spec is 200 ns. The 82C611 generates the read pulse based on
the MCA CMD signal, which asserts for only part of the
default transfer cycle. A fast machine like the model 90 has
a default transfer cycle time of 200 ns, so CMD is low for
only about 90 ns. This is too short to properly read from the
FM chip, meaning that Ad Lib auto detect functions will fail
to see the card."
