"SMD64KxC16": the SMD version of my homonymous Static-RAM expansion "64k xC16",
an original project that is well working since before June 2019: https://www.amibay.com/showthread.php?106843-C16-64k-S-RAM-internal-expansion-(no-motherboard-modify!)

This new version also fits C116!

It's funcion is to expand the C16 memory from 16K to 64K, as the PLUS4.
It has to be insert between the TED chip and the TED socket.

-Features:
1) internal installation (the cartridge slot remains free) without modifications on the motherboard.

2)16K/64K system can be selected via onboard switch or via optional remote switch.
The last batch has not the 16k/64k switch function (it is always 64k)

3) the energy used in S-RAM is equivalent to the energy saved by turning off the original Dynamic-RAM.

4) if you want 4 chips can be unsoldered (and replaced with empty sockets): 2xD-RAM (U5,6), 2x MULTIPLEXER (U3,4) to save energy and consequently reduce the internal temperature.

5) double pin construction: the C16 TED socket is very delicate socket, its contacts can be easily deformed,
therefore the expansion is provided with a coupling socket that has thin pins to adapt to a perfect C16-TED socket.
In case of already compressed contacts the "SMD64KxC16" can be directly plugged with its 0.4mm pins ...

"SMD64KxC16" is full tested also with diag 264 (CPU and TED access) and with 85MC01, CPU4C16.

An independent test:

Thank you.

expansion + tracked shipment for Malta will cost 23€, but for 25€ (shipment cost will be on the next weight step-cost) I can add a couple of C-Mos Rom for C16 (kernal & Basic) that absorb less than originals (so less temperature inside the C16...).

I'd be interested in getting two in the US (Michigan - postal code 48109). Quel prix?

2xexpansion + tracked shipment to US will cost 37€,
but for 40€ I can also add a couple of C-Mos Rom for C16 (kernal & Basic) that absorb less than originals (so less temperature inside the C16...).

This expansion was also placed inside a C116 without issues!
