Platform: Apple II, Apple II Plus, Apple IIe Form Factor: 50-pin slot card Speed: 3.58 MHz Cache: 4 KB cache DMA compatible: No Upgradeable: No Microcomputer Technologies (M-c-T) SpeedDemon card was the one of early Apple II accelerator which used the newer 65C02 microprocessor, and the first to implement caching technology.
The upgrade cost US$500, plus the trade-in of the user's existing Apple IIe motherboard and baseplate. Users would bring their Apple IIe machines in to an authorized dealership, where the 65C02-based IIe motherboard and lower baseboard of the case were swapped for a 65C816-based Apple IIGS motherboard with a new baseboard.

The original TransWarp took over from the standard 1-MHz 6502 or 65C02 used in the Apple IIe with a 3.6 MHz version of the 65C02 (which could also be run at 1.8 MHz, selectable through hardware) and turned on and off completely through software. The TransWarp was later followed by a TransWarp II and TransWarp III, the latter of which was ...
Like the Apple IIe itself, the Apple IIe Card uses an onboard 65C02 CPU. [3] The CPU is software-configurable to run at the Apple IIe's native 1.0 MHz speed or at an accelerated 1.9 MHz. Video emulation (text and graphics) is handled through software using native Macintosh QuickDraw routines, which often results in operations being slower than ...
The Apple IIe was the most popular machine in the Apple II series. It has the distinction of being the longest-lived Apple computer of all time—it was manufactured and sold with only minor changes for nearly 11 years. The IIe was the last Apple II model to be sold, and was discontinued in November 1993.

Technically the Apple IIc was an Apple IIe in a smaller case, more portable and easier to use but also less expandable. The IIc used the CMOS-based 65C02 microprocessor which added 27 new instructions to the 6502 , but was incompatible with programs that used deprecated illegal opcodes of the 6502.
The CMOS successor to the 6502, the WDC 65C02, also saw use in home computers and video game consoles. Apple used it in the Apple II line starting with the Apple IIc and later variants of the Apple IIe and also offered a kit to upgrade older IIe systems with the new processor. [70]
