Altos was a manufacturer of "standard" Z-80 systems. The Altos ACS 8000-2 in my collection was a later product of the company. The chassis is fairly simple with a single board Z-80 based computer running at 4 Mhz, a pair of Shugart drives (mounted upside down!) and 64K of RAM. The "-2" in the name means that this configuration has two single-sided, double-density drives installed.

The computer will run either CP/M (it came with version 2.21 set up for the hardware) or MP/M.

This machine came with a ton of documentation, software and a Televideo terminal (in need of refurbishment). It also came with two copies of WordStar and one of Microsoft Fortran.

I have two Altos Model 5-15AD (S/N 50 10523) with Viewpoint 3APlus keyboards attached to ADOS monitors, and software on 8 diskettes. Is anyone interested in this equipment?

I have a similar one- purchased by me in 1979 still working. Mine is 8000-2A with a little zoomier front face and woodgrain. My televideo 950 still works good. Came with Mannesman Tally 1000 printer, Altos/Dig Sys Manual, MS Multiplan, Peachtree MagicWand, FMS 80, MS Basic 80, and set of Digital System Interface manuals. Still works well (OK changing discs is tedious)- prefer the FMS data base manager
