Is there truly none of the default 15 banks that have Ram1       and Kernel mapped in at the same time?              I once needed to print a L!A!R!G!E amount a printer graphics data stored in       BANK 1. The program ran in BANK 15. I could have used the KERNAL utility for       fetching BANK 1 data but I chose to fuss with the MMU. I used a program to       select an MMU value        published in the GAZETTE section of a 1991 COMPUTE! magazine. Find       instructions for using the KERNAL routines for fetching data stored in other       BANKs in the C128 PROGRAMMER's REFERENCE GUIDE. JSFAR instructions are also       there.              --- SoupGate-Win32 v1.05        * Origin: Agency HUB, Dunedin - New Zealand | Fido<>Usenet Gateway (3:770/3)    |
