Low Cost ARCNET (ANSI 878.1) Controller with 2K x 8 On-Board RAM
The XTAL2 side of the crystal may be loaded with a single 74HC-type buffer in order to generate a clock
for other devices.
The user may attach an external TTL clock, rather than a crystal, to the XTAL1 signal. In this case, a
390Ω pull-up resistor is required on XTAL1, while XTAL2 should be left unconnected.
