vLA128 – Reliable ULA Replacement for ZX Spectrum 128K & +2
The original 128K ULA was a masterpiece of its time, but it is now the most common failure point in classic Sinclair machines. The vLA128 is a modern hardware implementation designed to replace the 40-pin ULA in the most iconic 128K models.
Key Benefits of the vLA128:

- Model Compatibility: Designed specifically for the Sinclair ZX Spectrum 128K (Toastrack) and the Amstrad ZX Spectrum +2 (Grey model).
- Drop-in Replacement: Fits directly into the original 40-pin DIL socket, making it a straightforward repair for hobbyists and professionals alike.
Technical Specifications:
- Compatibility: 128K “Toastrack” and +2 Grey.
