The turbo driver is not the 64k board. The MRB (master ram board i think) gives 64k. The turbo driver has 8k onboard and needs to have the cpu and rom desoldered from the motherboard an soldered onto the turbo board. You then add two sockets to the motherboard and push the turbo board into the sockets. You will need to check the motherboard as those with separate os/basic roms are not suitable for the turbo driver.
I think it works by bypassing the ula when accessing the first 8k of ram as this is a bottleneck in the 20k screen modes, I think the cpu drops to below 1Mhz when in these modes.

Thnks for the offer but I fancy doing these ones myself - It last some PCBs where I will actually be able to see the solder points.
Yes it is - I couldnt resist seeing how much of a change these things actually make to the humble Electron
Hiya syd
You are indeed quite right, I finally got round to a spot of googling.
I cant find any dox regarding installation or components used, or maybe even a few good close up piccys so I can get the parts...
I'm hoping it uses a std 6264 SRAM, which I have...
