Keyclick; Sounder; Operating System; Ram Backup Battery And The Mp2500 And Fs3 Disk - Husky MP2500 Manual

Keyclick

The FS/2 keyboard produces a key click, while the MP2500 and FS3
keyboards can produce a key click or a more audible beep (INT 16H
function 32H).

Sounder

The MP2500 and FS3 sounders are optimised for maximum output at
2.0kHz, producing less output than FS/2 at other frequencies.

Operating system

The standard MP2500 and FS3 operating system is MSDOS 6.22. FS/2 is
supplied with MSDOS 3.30a.
MSDOS 6.22 uses more memory than version 3.30a, which may cause
problems when loading large applications. The solution is to load parts of
the operating system into high memory, by using the HIMEM.SYS memory
manager and the DOS=HIGH command:

on this disk are secure irrespective of the state of the main battery or
backup battery.
• The MP2500 RAM backup battery will only support the RAM for 12 to 18
hours (less if not in its fully charged state); the FS3 RAM backup battery
