Zeprom & BankSwitching Message #1 Posted by Emmanuel, France on 7 Dec 2003, 4:22 a.m. 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: XFC7 100 ENBANK1 XFC9 180 ENBANK2 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. Edited: 7 Dec 2003, 4:23 a.m.

Re: Zeprom & BankSwitching Message #2 Posted by Diego Diaz on 7 Dec 2003, 12:20 p.m., in response to message #1 by Emmanuel, France 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. Diego.
