[Coco] Decent text editor for OS9?

[Todd Wallace]

Well guys, seems I got lucky.  Upon opening the CoCo3 i noticed the 512k ram board was not in all the way. i pushed it in place and the CoCo3 boots again.  However I DID notice that 2 capacitors near the powersupply have severe corrosion on the bottom.  I think I might be able to replace them on my own.  I really could use a solder sucker.  Maybe i'll ask a friend to do it that has access to one.  But in the meantime, the CoCo3 is running again!  I'll keep you posted if anything further happens.  Thanks for all the suggestions and advice! :-)
