vLA1 – The Ultimate Hardware Fix for the Sinclair Interface 1
If your Microdrives have stopped responding or your RS232 port is behaving erratically, the ULA (Uncommitted Logic Array) is the most likely culprit. The vLA1 is a brand new, modern hardware emulator designed to replace the original 40-pin ULA in the Sinclair Interface 1.
Key Benefits of the vLA1:
- Thermal Efficiency: The original ULA runs notoriously hot, often leading to its eventual failure. The vLA1 uses modern components that consume less power and run much cooler.
- Total Compatibility: Full support for all Interface 1 features, including Microdrive control, RS232 serial communication, and the LAN (local area network) port.
- Longevity: By replacing the most vulnerable part of the Interface 1, you significantly extend the lifespan of your peripheral.
- Easy Installation: Designed to fit directly into the original socket (or be soldered in place), restoring your hardware with minimal fuss.
Technical Specifications:
- Compatibility: Sinclair Interface 1 (all versions).
- Function: Direct replacement for the original Ferranti ULA.
- Power: Low-power consumption for reduced heat.
Information:
Does your Interface one have a small, shiny ‘spot’ – just in front of the interface connector on the top side? This is a classic sign your ULA is NOT doing well, and is running extremely hot. (We’ve actually seen them with an actual hole melted in the plastic case!)

NOTE: Due to a lack of room within the Interface 1 case, the original ULA will need to be desoldered/removed and the vLA1 installed in its place.
There is not enough room for a socket.
