Q/G separate or merged?

[Lars Brinkhoff]

According to this questions, some versions of TECO have separate storage
spaces for Q/U and G/X, perhaps starting already with Murphy's PDP-1 TECO.
MIT's PDP-6 and ITS TECO certainly have a single space.

Which TECOs have them split?

Hello Lars!
Of all the TECO UNIX ports I have seen - I never had access to authentic hardware of the era - all of them had combined Q-Registers (ie. each register has a numeric and string cell under the same name). My own implementation, SciTECO, also follows this tradition.
Best regards,
Robin
