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 functionality 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 etc.).
- 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.
