Re: If the R reg is used for video, how does it find time to refresh memory?
AFAIK Memotech (and Sinclair?) ram packs have their own refresh counter. And other ram packs often use static ram, which does not need refresh.
Futhermore any usual ram access also does a refresh of the accessed ram columns.

Re: Pascal for ZX81
There is a thread in the German Forum which gives possibilities to use partial Pascal without the need of using tape.

Re: Pascal for ZX81
If you have the manual as DOC (MS-Word) or Open Office file, I could do the changes in that document and send it back to you.
Or I could make screenshots of the errors and could add a description, what needs to be done.

Re: Pascal for ZX81
I found some misprints in the manual. And some functions and procedures are missing in chapter 5.13 (e. g. ram,usr,lsl,move,page).
Any chance, to update the manual?

Re: Where can I find a 5 pin din to twin Jack plug
Even if you have the DIN connector connected to a ZX81: the voltage levels at the DIN connector are much too low to be recognized by the ZX81 input circuit (DIN connectors use low levels and expect high impedance inputs, the ZX81 inputs are low impedance).
