84PCSE:RAM:987C

Synopsis

Hypothesized Official Name: plotSScreen

Memory Address: 987Ch

Length: 768 bytes

This appears to be the same as the old plotSScreen. It can generally be used for scrap RAM.

Comments

plotSScreen used to be used for storing a bitmap image of the graph screen. It is clearly not large enough to be used for that purpose now.

The OS never appears to touch this area. I suspect it's here at the behest of the Verilog and/or IQ Joe guys, in order to give them (and by extension, us) scrap RAM.

See also saveSScreen for another 768 byte block of scrap RAM.
