Monroe 925 Desktop Calculator
The Monroe 925 is a step-up from the slightly less-capable and less-expensive
desktop electronic calculator. The 925 upstages the 920 by
adding an additional digit of capacity (13 digits versus 12 on the 920)
as well as adding an accumulating memory register
that can be enabled by a push-on/push-off [AM] key that will automatically
accumulate products or quotients in the memory register. The memory register
can be recalled to the display with the [RM] key.
Other than these additional features, the 925
is functionally and visually identical to the Monroe 920.
Like the 920, the guts of the 925 were produced for Monroe by Canon in Japan
under an OEM manufacturing agreement.
Canon marketed a virtually identical
machine (other than color scheme of cabinetry/keyboard) as the
