The
TI-74 BASICALC is a mixture of the earlier CC 40 Compact Computer and a
conventional calculator. You have both a BASIC-language computer with a total of 8
kByte memory and a calculator mode with algebraical input and immediate output
on the huge alphanumerical display. The other features of the TI-74 are similar
to its sibbling TI-95 PROCALC. You may install RAM or ROM-cartridges in the
expansion port or connect the PC-324 printer to the
computer. The maximum capacity of the TI-74 BASICALC is 16 kByte of memory.
The TI-74 BASICALC System uses the following components:
| PC-324 | 24-column thermal printer |
| AC9201 | Mains adaptor for PC-324 |
| TP-324 | Thermal paper for PC-324 |
| CI-7 | Cassette interface |
| CM-8 | 8k Constant Memory Module (RAM) |
| Mathematics | Library (ROM) |
| Statistics | Library (ROM) |
| Learn Pascal | Library (ROM) |
| Finance | Library (ROM) |
| Chemical Engineering | Library (ROM) |
