I remember the Envyrn system.  Very nifty for its time.  I played quite a bit 
with the Mod 1/3 implementation and did a partial Coco implementation myself, 
though was too busy with other things to get far.

I liked and bought Softside for several years.  I was very disappointed that 
about the time they were going to add Coco support to the three BASICs they 
published listings in (after Mod 1, Atari and Apple) instead they split into 
three versions with listings for only one machine per.  I'd enjoyed comparing 
the listings of the same program three ways and translating some of those 
they didn't do all of.
