Good questions, let's see if I can help.
First of all I no longer have slots, working off of memory. But I do have a collection of sound files!
Never found any documentation for sound chip compatibility, learned through trial and error. What I did find is that the newer the Machine Chip, 8933-0041 in your case, the more sound chips that work. Even wrote a few custom of my own back in the day, can't remember what they sound like??
Your game and machine chip should be able to use most all sound chips available.
Now comes the "fun" part, writing the eproms.
First you need an eprom reader/writer that can write to a 24-pin 2732 eprom. (ebay)
Second you need an eprom eraser. (little ultra-violet light box) (ebay)
Third you need to find 2732 chips! And BE CAREFUL, there were some 2732's my old eprom reader/writer would NOT write to. Believe it was Texas Instrument brand.
You could use 2764 chips, 24-pin. You would have to double the file-copy it twice to the chip.(I see some ST brand 2732's on Ebay, I THINK those work)
Forth you should get some sort of eprom remover, (IC chip extractor) (ebay)
You erase the chips first by exposing the little glass window on the chips to a specific ultra-violet light, usually about 20 minutes.
The you set your reader/writer to your chip size and read it. The chip readout is Hexidecimal format. An erased chip is all FF's which in binary is all 1's. Your reader will show a zero content reading so you don't have to check the entire file!
You then upload the file you want to write to the reader/writer and write it. Your reader/writer will say file written or failed to write.
Your machine sound has two 2732 chips. Your current sound main master is the 8953-0003. You could MAYBE use the 8953-0022 master. Believe so.
I really liked the Main Master 8953-0022 with the 8953-0050 Data chip. Nice spin sound.
IF you go through the trouble of acquiring the devices above I would be happy to share my sound files (.bin) with you.
Let me know.
Another thing, make little labels for your chips as you create them!
