I was speaking to Roy McDonald of Connectix and he mentioned that you
can get the special Mac II(x) 4MB SIMMs with the PALs from at least 2 vendors:
	Peripheral Outlet	(800)332-6581
	Newer Technology	(800)678-3726
The prices that these vendors asked sounded competetive to those of the 
garden variety 4 MB SIMMs (based on Roy's mentioning of the prices; I haven't
personally verified this).

Connectix's literature for their Maxima product claims that Maxima will
also let a vanilla Mac II use (special) 4 MB SIMMs.  (And I quote from the
Maxima literature: "Original Mac IIs are normally incompatible with four 
Megabyte SIMMs but will run if MAXIMA is installed.")  Roy said that Mode32
will have this feature as well.  Neither of these programs require Mac II's
to get the HDFD upgrade.

Disclaimer: I have no affiliation with Connectix, Peripheral Outlet, or Newer
Technology, nor have I purchased any products from any of them (yet).
