vLA1: Sinclair Interface 1 ULA replacement

The vLA1 is a Sinclair Interface One ULA pin for pin direct replacement, using a modern programmable logic array.

The vLA1 provides full support for the Microdrive, RS-232 and Sinclair Network as in the original ULA.

These are new ULA replacements created and manufactured by Charlie Ingley. He sells these direct. Due to being located in New Zealand, postage and import costs to the EU/UK mean costs increase substantially. It is with pleasure to have worked with Charlie. In order to be able to resell these at a reduced total cost for you.

For full details please see Charlie’s site here: vdrivezx.com/vla1-sinclair-interface-1-ula-replacement/

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.
