TOUCAN'S TRIVIA: The first thing you might
notice about the TI-99/4A version of Espial
is its weird cartridge shape. This is due to the
fact that it plugs into the system's expansion port (where the Speech
Synthesizer plugs into) instead of the normal cartridge port. Most
likely Tigervision did this because TI would not license out
its GROM chips to many 3rd party developers. The GROM chip allowed for
greater amounts of memory to be put onto a single cartridge, and
without
the chip you were limited to 8K of ROM. Therefore, in order to fit Espial onto a cartridge
Tigervision had it plug into the expansion port, which allowed for
more memory than standard cartridges. |
