HP41C ROM Addresses
Just trying to make some sense of the ROM layout on the HP41C.

I know that the HP41C has 3 ROMs ROM0, ROM1, and ROM2 which I believe are are located at page 0, bank 1, page 1 bank 1, and page 2 bank 1.

I'm not sure what the page size it but if the HP41 uses a page size of 4K then the starting addresses of each ROM would be 0000h, 1000h and 2000h. Is this correct?

I'll worry about optional ROMs later!!

Thanks

Mike T.

HP21, HP25, HP32E, HP33C, HP34C, HP10C, HP11C, HP12C, HP32S, HP22S
