Apple Questions

A stock //gs used a 2.8Mhz 65C816 (16-bit registers, 24-bit addressing). So a speed comparison isn't totally valid, but an Apple ][ program running on a //c would probably be faster than the same running on a //gs. Never heard of that, but there was the Enchanced //e, which contained a 65C02 and an updated character ROM to include "MouseText", which has line and icon characters to allow for pretty windows and things. The basic //e models are: Original //e - white labeled keys, has old-style lid fasteners like the ][+ Common //e - black labeled keys, new-style lid locks, double hi-res mode Enhanced //e - keyboard has a smoother action, 65C02 processor, MouseText Platinum //e - same as Enhanced, "platinum" case color, numeric keypad There are a few revisions in between the various basic models. The regular //e could be made into an Enhanced //e with an enhancement kit which was just a 65C02 and the new character ROM. The original //e cannot do double hi-res graphics. There is also the Super ][ board of which only about a hundred were made, which was supposed to be the prototype for the //e.
