Wang 200/300-Series "Keyboard" Advertisement, November, 1969.
This is a revised version of an
(December, 1968) adding the 200-series to the existing 300-series
keyboard/display units along with the required and calculator electronics
The 200-series electronics packages differed from the 300-series
electronics packages by virtue of an extra circuit board installed
in the electronics package (which the keyboards plug into that contains
the actual calculating brains) that provide 1/2-cent round-off capability,
useful for financial calculations. Early versions of the 300-Series
Simultaneous Electronics packages (capable of driving up to four
keyboard/display units simultaneously) did not have a position in the
backplane for the 1/2-cent round-off function, but later versions
had slot that, when populated with appropriate circuit board, would
add the 1/2-cent round-off feature, making the electronics package a
200-series unit rather than a 300-series unit.
The 200-series keyboards would operate identically to the like-numbered
300-series keyboard/display units if connected to a 300-series electronics
package. For example, a 210K keyboard is identical to and operates the
same as a 310K Keyboard,
and if a 210K keyboard were plugged into a
300-series electronics package, there would be no 1/2-cent round-off
function. Similarly, if a 300-series keyboard is plugged into 200-series
electronics package, the 1/2-cent round-off will occur.
This ad provides summaries of two of the 200-series keyboards (200K and 210K)
with per-keyboard pricing if they were plugged into a 210SE
simultaneous electronics package; as well as providing per-keyboard pricing
for the 320K and
360K keyboards when
connected up to 320SE (for the 320K), or
360SE electronics package.
The pricing reflects the cost for four of the keyboard units (at the listed
price) including the cost of the appropriate electronics package, with
the marketing logic being that the per-keyboard price of a complete system
of four keyboards of the same type connected to a shared electronics
package is less costly per keyboard than buying four less-capable
electronic calculators from other manufacturers.
For example, a complete system of four 210K keyboards with a 210SE
electronics package would retail for $970 X 4; a total of $3,880.
That was a lot of money in late 1969, considering that a brand new 1969
base-model Chevrolet Corvette Convertible had a list price of $4,781, but
as a contrast, four NCR 18-2
electronic calculators of similar vintage and capability would cost $4,380,
$500 more than the Wang calculator system.
