If the user chooses, they may + supply their own font by mapping a 256 word memory region with two words + per character in the 128 character font. + By setting bits in these words, different characters and graphics can be + achieved. For example, the character F looks like this: + word0 = 1111111100001001 + word1 = 0000100100000000 + Or, split into octets: + word0 = 11111111 / + 00001001 + word1 = 00001001 / + 00000000 + + +Palette ram: + The LEM1802 has a default built in palette.

Once the SPC2000 is active, + the vessel will be almost nowhere to an external observer, and detection of + the vessel is beyond unlikely. + Because of the strong extra-dimensional acceleration and non-linear temporal + distortion that occurs, it's highly recommended that passengers are strapped + in and asleep when triggering the SCP2000. + + +Improvements: + * Added the ability to set the unit to skip to something other than the + default setting of milliseconds. + + +Interrupt behavior: + When a HWI is received by the SPC2000, it reads the A register and does one + of the following actions: + + 0: GET_STATUS + Sets the C register to 1 if the SPC2000 is ready to trigger.
