Robert, a small nitpick, there was also 160KB Card Reader modules available. (see here), Sylvain

I've read the brochures and EduCALC catalog listings of course, but I frankly don't believe they exist. Most importantly, I don't own one, and so they don't exist in my skewed reality. Until someone can produce evidence of one, I'll continue to deny they exist (but if someone does, I'll be wanting to make an offer or course...)

I know HHP advertised a 160KB module, but are you sure CMT did as well? I'm sure HHP planned to install a 32KB chipboard inside the module case along with the 2 x 64KB modules on the same board, similar to the way the 96KB module is configured w/3x32KB. Again, vaporware...
