I just picked this interesting little guy up for less than $9 shipped:

As far as I can tell, it is a Packard Bell branded 8-bit ISA Aztech Sound Galaxy BXII sound card. It isn't in perfect condition, but they don't seem terribly common, and it makes a nice cheap addition to my collection. This would be only the third 8bit sound card I have come across (along with my CT1350B and Midiman MM401). The volume knob and the YM3812-F OPL2 chip are pretty cool. 😎
Does anyone know anything else about these? I can't find much information on them, other than that some have had success installing CT1350B drivers for them (which, incidentally, I have original floppies of). I know the SB 2.0 doesn't do MIDI over its Gameport, but would these cards be capable of doing it? Are there any 8-bit midi+pcm cards that can? Its just something I've been curious about...
I recognized your sound card, so I had a look at mine and mine is a bit different.
Apparently you have one of the chips socketed while mine is soldered to the PCB.
I can't read the markings on your socketed chip, but my soldered chip had the following markings (they are a bit hard to read, so may contain some slight errors),
MHS
cAVS AZTDSP36 (the "c" is the copyright symbol)
S-80C51FASM
cINTEL 80,82 ("c" is copyright symbol again)
9309 (this looks to be a date code)
Your bottom-left chip with the Packard Bell sticker on it, is unstickered on mine and this chip has the following markings,
AZTECH
AZTSB0792-U07 (0792 is probably another date code)
JAPAN
9305P5005 (lots of date codes on the chip 🤣).
Yours probably is a similar chip, so if you want you can probably leave the original sticker on.
Your Yahama chip (in the middle above the jumpers) appears to have a slightly more recent date code of 9315 where mine reads 9302, followed by EAIB (can't read yours).
You have "Made in Singapore" in the top left where mine has "ASSB in Singapore" in the top middle (directly above that row of 6 very tiny resistors) and all of your caps and all of your tiny resistors are also on my card.
I know I stripped this card from an old system by my own hands and mine still has the original sound cable attached to the white socket, I think it's best if I take a pic so you know the wiring 😀.
My jumperblock appears to be the same, but the jumpers on mine are set up a bit differently (I never changed these so this is how it was extracted from its original system).
They are (from left to right) J2 2-3 J1 1-2 and IRQ7 (the IRQ jumper is probably kinda irrelevant for you to know though).
The long resistor-whateverthingy on your card is black where mine is blue (it's the one directly to the right and then slightly lower to the Yamaha chip in the middle).
Last but not least: Bottom left mine has a stciker with the part number, it reads "I38-SGBX21", so it's indeed some form of Sound Galaxy!
Pic to come (cellphone, but it's the best that I can do right now).
edit: Forgot to take a look at the back of the card as this usually also reveals interesting bits of info.
The date code in the PCB is 1293 and it has another date code printed in white font (almost looks like it's painted with a very fine paintbrush) 9319.
Theres also in the PCB the following: 50-0SC6AZ-2S-5

I had to cut some stuff from the pics as it was kinda reflecting everywhere 😵
Hope this helps 😀.
