Period accelerator card offered with a 65C02 or 65802 processor and 256K of high-speed memory.

This is a period product obtained used. Confirm the exact TransWarp revision and installed processor before buying.

• Apple IIe Exact model

Runs a 68030 CPU and 68882 FPU at 47 MHz for roughly twice the overall performance of a stock SE/30.

• Macintosh SE/30 Exact model

Recreates the 16 MHz 68030 MicroMac Performer accelerator for the Macintosh Plus, SE, and Classic, with an optional 68882 FPU.

Operation has been tested in the Macintosh Plus and SE, but not in the Classic; the maker has not found a socket that securely fits over the Classic's PLCC CPU. Host-specific U7 and SJ2 settings are mandatory. GAL16V8-15 and PALCE16V8-15 parts are tested, while ATF16V8 and other speeds are not.

• Macintosh Plus Exact model
• Macintosh SE Exact model
• Macintosh Classic Exact model

Combines an approximately 16 MHz 68030 and optional 68882 on a compact MicroMac Performer remix made for a Macintosh Plus clone.

The only documented Revision 2 installation is in a Macintosh Plus clone. The author expects an original Apple Macintosh Plus to work but asks users to report results, so stock hardware remains unverified. Installation requires desoldering and socketing the 68000, PLD choice is important, and some software may have distorted audio.

• Macintosh Plus Exact model

Adds a 16 MHz 68030 to a Macintosh Plus with a compact hobbyist-buildable board derived from the MicroMac Performer.

This build requires a PGA 68030, five programmed 16V8 devices, and soldering a socket on top of the Macintosh Plus 68000. The maker does not recommend the System 7.0 GemStart driver, reports garbled or intermittent audio, and warns builders to watch the first SIMM's clearance.

• Macintosh Plus Exact model

Accelerates an Apple IIe with a WDC 65816 processor and a replaceable 13 MHz oscillator.
