Successfully working on the Enterprise 128 using the same 8-pin DIN to CGA cable that I made for the Amstrad CPC6128 Plus.
The Enterprise RGB out uses a 14-way edge connector - you can buy cables with the correct connector still from a company in Spain that terminate in a SCART connector.
The Enterprise outputs R/G/B, H_SYNC, V_SYNC, C_SYNC and L/R audio on that edge connector.
As I had already made up a cable for the Amstrad I decided to remove the UHF modulator box and replace it with an 8-pin DIN socket. Plan to mount it on the inside of the case so the motherboard can be be removed from the case in future.
I used R/G/B, C_SYNC and L/R audio to match the Amstrad.
And ... it works. The image is a little unstable, occasionally losing V_SYNC (I think).
Maybe better to use the separate H_SYNC & V_SYNC signals into the CGA input, rather than C_SYNC fed into the H_SYNC input?
So, I've been able to use Ewan's little box successfully on the following:
[1] Amstrad CPC range (6-pin DIN)
[2] Amstrad CPC Plus range (8-pin DIN)
[3] BBC Model B (6-pin DIN)
[4] Yeno SC-3000H (8-pin DIN)
[5] Enterprise 128
