[Coco] Cloud-9's 512K Upgrade

[Little John (GIMEchip.com)]

Mark,
you should've seen the first 512K I made (and the subsequent look on dad's 
face).
I stuck two simms together with double sided sticky tape and used wire-wrap 
wire to connect the address lines of the simms together a0-a0 and so on - 
yep - soldered directly to the tiny holes at the simm edge fingers. then ran 
the wire wrap wire to connectors and plugged it all in. Dad was like - now 
how are you going to mount that mess, I said double-sided sticky tape. A 
lecture followed... that was three years ago.. I've learned a bit since then 
:-)
-John
