I also noticed that there is a "-RAMBOX 32" and a "-RAMBOX 1B" variant. However, I've never analyzed what the difference is. I've also seen 32K RAMBOXes with OS/B from the 41CY. They run fine, although the bank switching functions (PG<>, PG01 and PG10) obviously don't have any effect.

I have to dig it out and save the ROM image. I think your approach should work, however, I've never tried it as the 32K RAMBOXes I've got were all running fine. |
