	Sure is correct, in fact, I play some model 1 games in model 3 mode
   on my model 4; say that 10 times fast :^).
   The 4 defaults to being 100% Model 3, you have to tickle a few ports in
   order for it to realise its a model 4! Any model 3 software will work
   on a 4.

	LDOS 5.3 is all you need, it would help if you could get ahold of
   an old Radio Shack Hard Disk System Manual, an LDOS manual by any other
   name. Also, if you already have the TRSDOS 6.x manual you basically have
   the LDOS 5.3 manual. 5.3 comes with EXTENSIVE help built in so the manual
   isn't 100% neccessary. LDOS 5.3 has alot of nice features so if you have
   to be in model 3 mode, LDOS 5.3 is the only way to go. As a side, Misosys
   makes THE best software for the models 1/3/4, its owner, Roy Soltoff,
   wrote most of LDOS 5.x and a good majority of TRSDOS 6.x. Get a catalog
   if you order LDOS 5.3 from them, I think you'll get one automatically but
   it doesn't hurt to ask.

	YOU BET, It's a GREAT system and I have yet to find a bug. The
   timestamps are nice to have. I'm currently trying to figure out a
   clean way of manipulating time/dates in Misosys' C. I recommend 6.3
   100%.
