I agree, it's needed to lift the chip to the correct level - after I cut it and solder the socket, i put it back - it stays between the PCB and the chip - that works for me. However, I will try your advice to use curved tip as well. BTW, I see the original Creative chip is made by "SIGNETICS" - …

Is the AWE32 MIDI emulation with AWEUTIL under DOS working when you use the at89s52 with 4.0x firmware on your CT3900? And with 4.13? I think i always had that working, no matter what firmware i used. You mean the chorus/reverb/620h awe32 part of the card or anything specific? One thing that …

Is the available (thanks to MAME) firmware dump 4.13 identical for SB16 and for AWE32 cards? From disassembly of existing dumps, I can tell following: 4.04 and 4.05 are basically same with small improvements/updates, but 4.1x (4.11 and 4.13) is significantly updated with x-bus register transactions …

Works perfectly here on a burned chip. Also tried to dump a Signetics 4.12 chip i still had but that one seems to be locked.

Heres another firmware dump from a CT1730, v4.04. (needs to be decrypted) Can also burn roms and have both a socketed CT1740 and CT3900 incase you have stuff to be tested. AT89S52 is a drop in replacement aswell, which is what im currently running in my card.

Its a CR-563-C drive, should be 2x speed from what i can find. So far the standard Sound Blaster 16 drivers work fine (for all the audio), just looking into the drive part as thats not getting power. (Its working though seperately from the enclosure)

I'd drop unisound for now and go back to a default creative driver setup first, to rule out any driver errors. And run everything in msdos.
