Assembler package TASM v4.12 for Pentagon 512

TASM is a software package designed for the Pentagon 512 computer, offering an advanced version of the TASM 4.12 and STS 5.1. This package is specifically tailored for the Pentagon 512k model, ensuring compatibility and efficient memory distribution. It is notable for not occupying the 128th memory and remains unaffected by a RESET command.

The program features a loader that automatically restarts the assembler if TASM is detected in memory. Users can force the loading of TASM by pressing the 'T' key at the beginning of the loading process. The STS component is always loaded with the package, ensuring seamless operation.

Memory allocation within the package is structured as follows: TASM utilizes pages 81, 83, 84, 86, and 87, while STS uses pages 87 and 81. This organization supports a hybrid operation mode, combining the features of both the PROFI and PENTAGON systems.

The software includes a detailed modification scheme for upgrading the PROFI computer to a hybrid model, compatible with the PENTAGON 512. This upgrade involves specific hardware adjustments, allowing the computer to operate in multiple modes, including PROFI 512 and SPECCY 128.
