MOD
B
The WANGCO
Mod
8 is a low-cost, highly reliable digital magnetic recording system
which is ideal for small computers, data communications systems, key tape systems
,
and data conversion systems. Fully IBM-compatible, the
Mod
8 has been designed
to plug into most low-cost systems controllers.
With standard tape speeds of 12.5, 25 and 37.5 inches per second
,
data is written
and read at densities of 200, 556, 800, or 1600 characters per inch. The
Mod 8
accepts IBM hub-compatible reels up to
81f2
inches in diameter. IBM-compatible
7-track and ANSI-compatible 9-track versions are standard.
Consisting of a tape transport, transport electronics, data electronics, and a power
supply, the
Mod
8 has an extremely simple, reliable design. In addition, it has many
exclusive features which enhance performance, reliability, and ease of operation
well beyond other tape handling systems in its price range.
Among the unique
Mod
8 features are (1) the use of IBM head guide spacing for
reliable tape interchange, (2) variable electronic write deskewing in each channel
for NRZI
,
and (3) a tri-Ievel read threshold including a programmable level for
recovery of marginal data. In addition
,
a simple tape-threading path and a quick-
action
,
hold-down knob permit convenient threading and unloading in a matter
of seconds.
