vLA82S+ Spectrum ULA Replacement with RGB video and AY Emulator - without cable interface

The vLA82S is a modern plugin replacement for the Spectrum 48K ULA (type 6C001E-7 or earlier) which combines the original vLA82 capability with the addition of an RGB video interface and AY compatible sound. It is one of several ULA replacements I have made for members of the Sinclair computer family including the vLA81 for the ZX81, the vLA128 for the Spectrum 128K (Toastrack) and 2 (Grey case) and the vLA1 for the Sinclair ZX Interface 1.

Note: No cable interface is provided. An 8 pin JST socket is located on the under side of the PCB to provide interface signals. This product is for existing vLA82S owners who already have the interface and cable, or for customers who would like to create their own cable interface.

vLA82S Features include:
- Plugin ULA replacement. In most cases the existing socket will be OK. Note that turned pin sockets can give problems with the narrow pins the vLA82S uses.
- Programmable Sound Generator (PSG) compatible with the AY-3-8912.
- A low profile and 40 pin DIL footprint means that the vLA82S is designed to fit in a ‘rubber key’ ZX Spectrum case without further modifications.
- Provides the same basic as the 6C001-7 Sinclair ULA. as well as supporting the higher quality video and sound enhancements.
- Passes standard ULA benchmark tests (floatspy, Brendan’s Diagnostic ROM.).
- Tested with an extensive suite of ZX Spectrum software.
- Compatible with lower ram replacement modules.
- Ideal for installing in an aftermarket Spectrum PCB without needing an original ULA.
- Low power consumption.
Whether you want to just get a faulty Spectrum back up and running, or need a ULA replacement for a new clone, then the vLA82S is exactly what you need.
