Hey guys, it's a shame for me to miss such a thread here! I've already posted about possible GUS PnP Upgrade, so let me share some ideas here also. Sure, the IW78C21M1 chip is a 1 MiB Flash ROM. One can figure out its pinout on the GUS PnP PCB (Gravis actually provided for another - DIP - package …

I just found out that this gus is just a cult sound card, audio from demos and games are cool, but sometimes it can get crappy. For the money these are being charged, it's much better get a roland /xg board and a nice sb compatible card with no hanging notes feature. Gus pnp has no real software …

If I could borrow one from a gus pnp or other I would test it for sure 😀 It doesn't break if we try 😁

is there a way to dum those roms? Are they protected? They are just like db50xg and other daughterboards.

They offer the sets to upload in ram, not in rom I think.

So the classic would be a better bet?

yah, they are not protected 😀 They can be read easy or not if they changed pins. maybe we can use a flash by changing the circuit a bit

This rom is used in Korg http://www.datasheetarchive.com/dl/Scans-059/ … A2IH0049163.pdf . Back in those days a flash was expensive I think, a rom was cheaper. This is very similiar to mx rom 1mb. Maybe I would try to see it as a m27c160 😀 psop44

Hi! I have the option to choose between these 2 cards on topic, wich one is the best to go? I already have an awe32 (ct3980) with xr385 (on the way). I see so many coments about gus pnp compatibility issues and gus classic being great. But also that gus pnp is much better in hardware. Were those …

If you see a db50xg, you can find the same chip, but rebranded for yamaha.

Oh! let me tell you, I think IW= interwave so IW78c21m1 is a rebranded memory from MX, not FIFO as I thought, and it might contain info for wavetable. Maybe it's a flash with wavetable data. 1mb to be more precise. Could it be a 29f800? Could you tell me where is VCC and GND on that IC? Thanks!
