NOTE
GETCs using EPROM 349A9607G4 or later must
use Logic Board 19D904266G4 or upgrade the
Logic Board 19D904266G1 with the Speedup
(80C320) microprocessor and Amps Modem
chips, U4 and U19 (19A704727P4). (Refer to
Upgrading Hardware in the Hardware Installation
section of this manual.)
GETCs using EPROM 349A9607G4 or later must
also have the FerriShield Toroid (REG70469/1)
installed around the Turbo Board’s harness for
EMI suppression, refer to LBI-28822 for details.
