Replaces the Z80 and upper 32 KB of DRAM in a ZX Spectrum 48K, Spectrum+, or Timex TC 2048 while adding AY sound.

For this system (exact model): The seller explicitly names Timex 2048. Confirm the exact CPU footprint, board orientation, RAM-disable method, and audio wiring before invasive work.

The seller exposed a login-or-register-to-buy path for MAMLAS on 2026-07-27; its Z80SRAM predecessor is discontinued. MAMLAS installation is invasive: remove the original CPU and any socket, disable or remove the upper 32 KB DRAM, and solder the module directly at the CPU footprint with correct pin-1 orientation. The audio connector is not included, and a ZX Spectrum 48K heat sink may need to be bent for clearance. Do not install the module on top of its shipping or protective bottom socket. Used Z80SRAM boards should be treated as a distinct earlier revision and checked against their archived instructions.
