The
RCA
VP-601
keyboard
has
a 58
key typewriter
format for
alphanumeric
entry.
The VP-61
1
($t
S
additional.)
offers the same
type-
writer format
plus
an additional
1
6
key
calculator
type keypad.
Both
keyboards
feature
modern
flexible membrane
key
switches
with
contact
life rated at
greater
than
5
million operations,
plus
two
key
rollover
circuitry.
A finger
positioning
overlay
combined
with light
positive
activation
key
pressure
gives
good
operator
"feel",
and an
on-board
tone
generator
gives
aural
key
press
feedback.
The
unitized
keyboard
surface
is
spillproof
and
dustproof.
This
plus
the
high noise
immunity of CMOS
circuitry
makes
the
VP-601 and
VP-61 1
particularly
suited
for
use
in hostile
environments.
'
The
(eyboards
operate
from
a
single
S-volt,
DC
power
supply,
and
the buffered output
is
TTL
compatible.
