It will expand the memory of your C16 to 64K as a PLUS/4... and an option for replacing ROMset to enable
"3+1" FUNCTION software saving supply current (lowering internal temperature...)
It's very simple to instal:
open your C16, pull out the TED chip, plug the TED on "64KxC16", place the "64KxC16" on the TED socket, close your C16...
Not cutting traces, not desoldering anything!
(All the 64k RAM expansion cartridges require that some motherboard traces has to be cutted for removing the old ram bank and avoiding a bus conflict, and it imply that C16 can't work without plugging the ram cartridge)
There is a switch for chosing 16K or 64K system, and a 2 pin plug for the remoting of the switch.
Power absorbed by this expansion is equivalent to the energy saved by stopping the access at the original memory bank, it's possible only because it was chosen a Static RAM that use much less power of a Dynamic RAM (original one is D-RAM): not more power, not more dissipation, not more heat...
NOTE: it will be mechanically not compatible whith C16 rare models that use a metal schield inside for covering the motherboard, the standard shield type is a metallized paper, and this is mechanically compatible

The ROMset option, and your C16 became a +4 (without user port...):
