Max-80
personal computer
The MAX-80 is a personal computer released in 1982 by Lobo Systems (formerly Lobo Drives International, a company from California). It differed from other TRS-80 compatible computers in that it was not hardware compatible with the TRS-80.
Hardware
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 64KB of RAM, and was expandable via sockets for a further 64KB.
The standard configuration originally consisted of a 64KB unit (later 128KB) and CP/M. The user could buy a complete system, or provide their own monitor and disk drives.
The floppy disk controller could handle 8-inch drives using the standard IBM 3740 format in single-sided or double-sided modes, as well as 5.25-inch floppy drives with up to 80 cylinders. The Max-80 included a hard disk interface and two RS-232 serial ports. The MAX-80's character generator was user programmable.
Software
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 public source identifies “Max-80” as personal computer. This brief keeps that definition visible, then builds a research path around Max-80, personal and computer.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Max-80”, the useful work is to connect “personal computer” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 1, 2026. The linked authority identifier is Q6794484. The first chronological checks are 1982.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
