Hypothesized Official Name: saveSScreen
Memory Address: 8798
Length: 768 bytes
This appears to be the same as the old saveSScreen. It can generally be used for scrap RAM.
saveSScreen used to be used for storing a bitmap image of the screen after powering-off. 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 plotSScreen for another 768 byte block of scrap RAM.
