The vLA81 is a modern plugin replacement for the ZX81 ULA. It is one of several ULA replacements Charlie has made for members of the Sinclair computer family including the vLA82 for the Spectrum 48K, the vLA128 for the Spectrum 128K (Toastrack) and +2 (Grey case) and the vLA1 for the Sinclair ZX Interface 1.
As they simply don’t make ZX81 ULAs anymore, then unfortunately if the ULA has failed (and there’s not much else on a ZX81 to fail), then options for repair are rapidly diminishing. The vLA81 provides a simple way to keep these icons of 80’s computing going.
Apart from providing the functionality of both the earlier 2C158E/184 ULA (without back porch) and the 2C210E (with back porch), the vLA81 also has a few extras added.
Here at ZX Renew we love retro computing as much as you do. That's why we are passionate about bring you the BEST in high-quality replacement parts to keep your retro computing journey going into the future.
