The Yamaha AN1x Synthesizer mailing list

Vadim,

Thank you for the file! The file you sent is a 1mb file. This means that the eprom must be a 27C040 or 27C4001 4096k chip. These eproms are more expensive than the smaller 256k or 512k chips. No biggie it is still an easy thing to make I just need to get some more of these eproms....

Thanks again, Fran

Fran, check your email

But the Rom chip used in AN1x is not the same as in Rm1x as far as I know.
Chip used in Rm1x is still available and cheap. But I didn't find chip used in AN1x.

regards, Vadim

I had a similar issue with my RM1x, but some very helpful members of the yahoo group, uploaded a bin file into the files area. Another member offered to burn and supply the latest os chip for a few pounds.
I was easily able to update then to the latest os.

Does require a couple of members who have relevent equipment and knowledge. It was an excellent example of self help among group members.

Unfortunately, I only have version 1.02 as well.
