Aresco Newsletters

[Matthew Mikolay]

Hi all,
Out of curiosity, did anybody on here subscribe to any of the newsletters published by a company called Aresco back in the late 70s and early 80s? These newsletters were VIPER (Cosmac VIP), Paper (Commodore PET), Source (Exidy Sorcerer), and Rainbow (Apple II). Aresco also published a series of books by Tom Swan titled PIPs for VIPs.
I own several issues of VIPER, but I'm still looking for copies of the others. Does anybody have these newsletters in their collection?
