The Mac LC II (a.k.a. Performa 400, 405, 410, and 430) has 4 MB of RAM soldered to the motherboard and room for two additional SIMMs. (Apple says that some LC IIs have 2 MB of onboard RAM, but I have never run into one.)
Second Class Macs are Apple’s somewhat compromised hardware designs. For the most part, they’re not really bad – simply designs that didn’t meet their full potential. The LC II (a.k.a. Performa 400-430) was a slightly less crippled version of the LC.
I first came into contact with Apple Macs back in the early 1990s when my friend’s father purchased a Mac LC II. At the time I thought it was a load of rubbish (hey, I’d only ever used Nintendos and an Amstrad 6128+).
1998 – Readers ask about options to upgrade old 68030-based Macs, the Classic II and LC II.
