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.
