If you are programming in BASIC, you need 2K
to 8K of memory for the average simple home fi
nance program. A program to perform practice
exercises in addition or subtraction may use from
4Kto10K.
If you use cartridge software, each cartridge
contains an additional 30K of memory that is
used by the cartridge program. While you can
not access the memory in a cartridge from a
BASIC program, this memory is used by the car
tridge software to perform various functions.
Much of the available software for the TI-99/4A
does not require the use of any additional mem
ory. So, for most applications, you should not
need additional memory in your computer.
Some business applications and advanced
programming languages do require additional
memory. For those applications, you need a
memoryexpansion card The Tl Memory Expan
sion Card (about $300) plugs into the Tl Periph
eral Expansion System and adds 32K (about
32,000 characters) of memory to the computer.
