We have just started the re-issue of the ADR F760 in the Helios Format, which excludes the Exp/Gate, we decided to keep the PCB's and all the components we use is exactly the same as the original.
The Helios complete module will not be ready until August but the PCB's, "A" or "B" either loaded or empty are now available.
All of our work has been endorsed by Ian at ADR, as we have been servicing all ADR classic gear including the Scamp range for the last 20 years.
Best Regards
