Adapts a W65C816 processor to a 65C02-compatible socket while generating the missing clock and synchronization signals.

The board was out of stock on 2026-07-24. It adapts processor signals but does not provide an independent accelerator clock; the stated 14 MHz is a board capability, not a promise that an Apple IIc will run at 14 MHz. Confirm socket type, clearance, and host timing before installation.

Adds an internal AY or Yamaha sound generator and stereo output to a ZX Spectrum through a CPU adapter.

Lotharek marks the interface discontinued. The AY chip and audio connector are not included. Plug-in installation assumes a socketed CPU; otherwise safe CPU desoldering and socket work are required. Preserve pin-1 orientation at the CPU adapter, ribbon cable, and sound-chip board, then provide the documented stereo and ULA-audio wiring.
