2nd Life

2nd Life is a complete TRS-80 Model III emulator for Atari ST, STE, TT, Falcon or compatible computers. It can be used to run most TRS-80 Model I and III programs. It emulates the Z-80 microprocessor, video subsystem, keyboard, cassette relay, printer port, internal clock, floppy disk controller and four 80-track single sided disk drives. The emulation code is written completely in assembler, and as a result the emulated computer runs on a 16 MHz 68000 (STE) virtually as fast as the original machine. But even on an 8 Mhz ST the perceived speed is close to that of the original machine, as the emulator optimizes key ROM subroutines.
