A lot of other non-BASIC software would also be incompatible. The second 40 column bank DOES reside at $800-$bff, Just try turning the second page on when still in Text mode, (Or low res graphics). Sure this is incompatible with Applesoft, thats why its not used much anymore. Integer Basic programs were able to use both pages, also, if you moved your Applesoft program to $4000, you could load in 2 low res pictures and flip betweem them. (Animation...). I doubt that the 80 column hardware supports the second low-res page. -Gadi -- ARPA: friedman@topaz.rutgers.edu UUCP: {harvard, seismo, ut-sally, sri-iu, ihnp4!packard}!rutgers!topaz!friedman CMS: RUTGERS!SYSOP (CMS is DOWN.
