GoldStar is the "G" in LG. I (my parents) had a 286 DOS machine by them when I was little.
No sound card though...

Thanks for the link! there does not seem to be any FCC ID number on this sound card 😖 ... after more looking it could also be an Aztech sound 4 or sound 3 card! I may as well bin this one and buy a Yamaha OPL3 based ISA card 😁

I had a Packard Bell P150 system years ago and I can tell you they used the cheapest parts available. I wasn't able to carry anything over from that machine when I upgraded because it was all crap. The only thing I was able to get away with with that machine was kick up the P150 to a P200 after I read somewhere that all P150 chips are really P166's running with a slower bus and the vast majority of P166's can handle overclocking to 200mhz easily.

We had a Packard Bell dot matrix printer that didn't have a driver, after getting Windows 3.1 we needed "emulation" by using drivers for other printers by IBM and Epson, which would rarely work properly, or use "Generic Text-Only" which wouldn't allow graphics. 🙁

On our friends' Packard Bell computers with Win 3.1, I noticed they had their own Progman.exe. Don't remember though.

I know it's an old thread but for the sake of completeness and because I own one of this said "AZT3002 PNP" card here are the infos I found recently.

It seems these cards were generally marketed as Audio Telephony combo cards, and original Aztech driver page is https://web.archive.org/web/20030227125355/ht … hony_at3300.htm

Files have been mirrored here: https://ftp.zx.net.nz/pub/mirror/ftp.aztech.c … /Audtel/at3300/

It's what works best under Win98SE.

For MSDOS7 I'm using UNISOUND

Note: Under MSDOS, I failed to have AZTPNP.CFG correctly created with the official AT-3300 drivers and I failed to initialize FM sound with UNISOUND.

Thanks, I also have this card and was struggling to get the full driver for it - Windows 98 has a working WDM driver but nothing for the modem and WDM is no good for DOS games. This was a big help for figuring out how to get it working 😀

Initially I was looking on driverguide for azt3002.zip but that seems to have gone back to being a full-on scam site now and doesn't provide the zip file. Your website and this post should get my card working too.

74LS74 probably isn't a DAC? From what I can gather, said number means a D-type flip-flop chip (with various reset, set, data (1-bit), clock input and query(both normal and inverted) pins on it. So it's used to set a 1-bit value (clocked by the clock rising), set the value (strobe), clear the value (strobe) or query it's live outputs (either inverted or directly).
Said chip has 2 of those flip-flops available on 2 sets of pins (1 set for each bit).

You are correct. That wrong guess is 15 years old, though. Typical applications for 74LS74 chips are to delay a signal by 1 clock cycle, to synchronize a signal to the rising edge of a clock, or to store a one-bit state.

Photos aren't loading for me, but this is almost certainly an mwave monstrosity, if I had to guess.

Sorry to have bumped such an old thread but pjturpeau's website really helped me out so I wanted to say thanks. IT's an Aztech 2320 card with integrated OPL3 and a modem stuck onto the ISA card, works very nicely now it has all the drivers 😀
