replacement for the V1.1, V1.3 and V1.3A EPROMs as does not have
support for the mouse, but does contain all other features of these
EPROMs.

Please observe correct handling procedure for ESD devices as the EPROM
is easily damaged by static electricity.

WARNING -- if the V1.6 EPROM is reversed in the socket it will be
destroyed the moment that the 2001 is powered up !!!!

Note: HQ mode should only be selected when Martin mode has been
selected first, all other modes and functions are as described in the
V4.0, V4.2 and V4.2A instructions.

To select the HQ modes with the receive picture sharpening enabled
(preferred), press the "2" speed key to select HQ 1 (90 Sec.), press
the " 1" speed key, to select HQ 2 (112 Sec.), for use when conditions
