Introduction
The AltairZ80 simulator is part of the
SIMH family of
simulators. The version on this site includes some simplifications
and bug fixes not present on GitHub.
Unlike a real Altair 8800 it features several enhancements:
- Choice of processor (8080 CPU, Z80 CPU, 8086 CPU or Motorola 68000 CPU)
- Optional banked memory (16 banks with 64 Kbyte)
- MMU supporting ROM and memory mapped I/O
- Optional hard drive support for additional storage
capacity
- Networking support via TCP/IP for client/server
systems
- Support for multiple consoles
- Timer and keyboard generated interrupts
- Various devices for NorthStar, Vector Graphic and
CompuPro
- Ability to set the clock speed for "real-time" simulation
(useful for games)
