I only remember the II+, but both were dense with chips. The IIe had fewer chips as I recall. That level of complexity wasn't unheard of at the time. When the IBM PC came out, only a few of the chips were in sockets (the CPU and RAM/ROM), and people were nervous about repairability, but IBM pointed out that they had studied it to death over the years, and that the chips were more reliable than the sockets.
