Reactor owners - need ID on RAMs

[MarcelG]

Hello. Working reactor? I need to know what kind of RAMs (6116, 2128, etc) are in installed physically at the locations:

Above Game ROMs:
"RAM0", "RAM1"

Middle of board:
"E7", "E10-11", "BG0", "BG1"

Thank you very much for your time in advance!

BG0 & BG1 are not rams, they are eproms. These are the roms for the background.
E10-11 & E7 are MK4801 rams. 6116 will also work here.

Not in Reactor, there are RAMs in BG0 and BG1.
Manual states 8128s (2k x 8), I have 6116s in place. Are they the same?
