The vLA81 is a modern plugin replacement for the ZX81 ULA.
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.
vLA81 features:
- Fits within the same 40 pin DIL socket outline as the original ULA.
- Narrow IC pins for easy plugin ULA replacement. In most cases the existing socket will be OK (unless, of course, the existing ULA is soldered in).
- Provides the same functionality as the 2C210E Sinclair ULA.
- Video level selectable between standard video (suitable for direct connection to a 75 ohm monitor input) and high sync level (suitable for the modulator input or some video mod boards).
- Back porch on/off select.
- Internal 32K memory support (High or Low for the different hires schemes).
- Programmable user configuration gives access to:
- Inverse or normal video and choice of black or white border.
- 50/60 Hz video standard.
- Ability to map ram to the ROM space (write protect enable/disable – 32K internal ram required).
- Tested with an extensive suite of ZX81 software.
- Ideal for preserving the original ZX81 ULA.
- Low power consumption.
Whether you want to just get a faulty ZX81 back up and running, or want to extend the ZX81 with expanded memory and HIRES, the vLA81 can provide what you need.
- full compatible with original ULA
- low power consumption
