I was under the impression that the Triad and Kip's new Memory upgrades are actually using larger RAM chips, and only providing 512k of the available memory.

So, except for the new circuitry to provide the access to the additional memory, there should be little additional power draw from a 1mb or 2mb board.

I want a 512k upgrade for my Coco 3, but it's not urgent and if a 2mb board is coming -- I might as well wait and just keep saving my money.

Somewhere I have an unused Dennis Lewandowski 256k upgrade for the Coco 1. I never used it, and I wonder if it's still workable. It's just a bunch of chips piggybacked and daisychained with wires. If I come across it, I'll take pictures and post it.

I have lots of little goodies like this, because I was often checking out possible new products for Spectrum Projects and Zebra Systems.
