The MAX-80 is a personal computer released in 1982 by Lobo Systems (formerly Lobo Drives International). It differed from other TRS-80 compatible computers in that it was not hardware compatible with the TRS-80.
The MAX-80 featured a Zilog Z80-B CPU which ran at 5.07 MHz, a very fast speed for its time. It came standard with 64k of memory, and was expandable via sockets for a further 64k. The standard configuration originally consisted of a 64k unit (later 128k) and CP/M. The user could buy a complete system, or provide their own monitor and disk drives.
Up to 95% of TRS-80 Model III software would function without modification on the MAX-80. This did not include games. The special version of LDOS used was able to run most Model III programs with a patch disk available for those, such as VisiCalc, which it couldn't. The CP/M operating system was offered as well.
