[Coco] 2MB CoCo3 expanson board "bounty"

[Bill Pierce]

Tony, the 1-2-meg's "dat" board is soldered directly to the 6x09 (all pins), there's no pulling the board for loan. The actual memory is plugged into the same place where the 512k goes, but without the dat, you're no where.
Here's some pics of what the 1-meg looks like (before I cleaned the system up).


This is the dat board soldered to the 6809

This is with the 2nd 512k mounted on top the first.

The first 512k (mounted in the MB sockets) is the disto upgrade, the "upside down" 512k is a standard Hemphill 512k upgrade.
The board connected to the keyboard ribbon cable is the Eagle AT Keyboard Interface.

Maybe the 2MB board is a good item for our first "bounty."

If you guys aren't familiar with the concept, other platforms use/have used it.
They set up a "bounty fund" that people interested pitch into, and whoever does 
it and completes it, gets the bounty fund.

Now, this bounty fund is for the engineering/development - when it's ready, then 
all have to buy it.

Engineering/designing/layout take time, and the bounty encourages that.

When ready, setup the PCBs for manufacture with say OSHpark or whoever, and 
everyone goes to town.

Who's interested, and has the experience, capability, and time?
Anyone got a 2MB board they can loan to this person for reverse-engineering?

2MB board is definitely something I'd like 1-2 of...

Cheers!

Tony
