I'm actually studying how to 'bankswitch' a Zeprom module.
I would like to burn the Hepax Rom I have yet (1B, 1C or 1D).
Curiously only two adresses have codes:
XFCB and XFCD don't have ENBANK3 and 4, just NOPs (?!).
I understood the principle but would like to know if someone had experience in that activity.
Thanks for assistance.

Hi Emmanuel,

It may be me the one to blame... sorry, as for the Addresses you've checked, it semmed like if you have took a look at a previous post I wrote to Meindert Kuipers regarding a similar question. If so, my apologies go to you.

Those addresses were wrong, (not too far though :-)

Here you are the correct Bankswitch & Retun Addresses:

XFC3: H'140, H'3E0 ENBANK3

XFC5: H'1C0, H'3E0 ENBANK4

XFC7: H'100, H'3E0 ENBANK1

XFC9: H'180, H'3E0 ENBANK2

Hope this helps.


Yes, you are right and I was wrong.
Please accept my apologies.
Thanks to remind me of that point.
I'm loosing my memory...Sorry I'm aged. ;o)
