SNA*ps 3270 v1.0.1 (the client software) is compatible with the Macintosh
Quadra computers. However, you may have done an Easy Install or a Custom
Install, and selected SNA*ps CUT and SNA*ps NLCA. In this case, you must
remove the extensions, SNA*ps CUT, and SNA*ps NLCA from the Extensions
folder. These extensions aren't compatible, and SNA*ps 3270 will hang
when you launch it.
The preferred way to install SNA*ps 3270 on a Macintosh Quadra is to do a
Custom Install and Choose "SNA*ps 3270 Client, System 7."
The original Macintosh Quadra compatibility booklet distributed with the
Macintosh Quadra computers and the compatibility report posted on AppleLink
say that both SNA*ps Gateway and SNA*ps 3270, versions 1.0 and later, are
compatible with Macintosh Quadra computers. Only SNA*ps 3270 is compatible
if you follow the above guidelines.
Note that only a few copies of SNA*ps 3270 version 1.0 were distributed
before SNA*ps 3270 was revised to version 1.0.1. There are no functional
differences, only a cosmetic one with one dialog.
