WHICH ADD-INS WORK

Preliminary testing of 1-2-3 on the 95LX produces some disappointing results regarding add-ins. Add-ins that only implement new @functions should work; others will probably not. We have tested the current versions of 14 popular commercial add-ins. Here are the results:

These don't work: SeeMORE (Personics); @BASE (Personics); Look&Link (Personics); Macro Editor/Debugger (Personics); Sideways (Funk); Allways (Funk); Noteworthy (Funk); Worksheet Utilities (Funk); 2D graphics (Intex); 3D graphics (Intex); 4WORD (Symantec); Budget Express (Symantec)

These do work: Rescue (only some parts) (Intex); @EASE (Spreadsheet Solutions) There are a variety of technical reasons. The two major reasons are:

1. Most commercial add-ins hook into 1-2-3's jump table which is in the code segment. In the 95LX, the code segment is in ROM which makes it rather hard to change!

2. Some add-ins use their own drivers. The 95LX has a hardcoded driver set.

It also appears that once you attach an add-in, you should not detach it. We're doing some additional testing to narrow this problem, but at the moment it appears that detaching an add-in can quickly lead to a system crash.
