[Coco] Decent text editor for OS9?

[Bob Devries]

Todd,

before you go removing those power supply capacitors, please be aware that 
the manufacturer used glue to be sure that vibration wouldn't dislodge those 
caps. That glue was a brown colour (at least in the ones I've seen).

Regards, Bob Devries
