in the datasheet of mc6802 microprocessor is written "microprocessor with clock and optional ram". do you know what is "optional ram"?
 

The MC6802 has 128x8 on-chip RAM ..
However, this RAM can be enabled (by RE = RAM Enable pin) to respond to the MCU controls or can be disabled and thus de-facto not present ..
Therefore it is called "optional" .. (see description of this RAM in the MC6802 data sheet: https://www.datasheets.org.uk/search.php?q=MC6802&sType=part )

Regards,
IanP
