[Coco] New video from Cloud-9!

[Bill Pierce]

With the old Performance Peripherals 512k upgrde, only one resistor is cut, the old memory is pulled out (socketed) and the unit just plugs in. So going back to 128K would be a ,matter of pulling the unit, connecting that resistor and replacing the memory chips. I have 2 of these units in old Cocos I hope to revive one day

I think Luis is saying he'd like to have the ability to switch his 512K
CoCo 3 into a mode appropriate for testing software to see if it runs okay
on a 128K machine.  Easier said than done, I suspect;  better to have
somebody with a 128K CoCo test it.
