Mac, the appleII
The Apple II Plus total of 48 KiB of RAM, expandable to 64 KiB by means of the language card, a 16 KiB RAM expansion card that could be installed in the computer's
slot 0. The Apple's 6502 microprocessor cansupport a maximum of 64 KiB of memory, the extra RAM in the language card is bank-switched over the machine's built-in ROM, allowing code loaded into the additional memory to be used as if it actually is ROM. Users can thus load Integer BASIC into the language card from disk and switch between the Integer and Applesoft dialects of BASIC with DOS 3.3's INT and FP commands just as if it had the BASIC ROM expansion card. The language card is also required to use the UCSD Pascal and FORTRAN 77 compilers, which were released by Apple
