Re: Sinclair Sovereign Calculator
Good evening Mark,
Great, thank you.
It is really difficult to get any information on the capacitors in the Sovereign.

Sinclair Sovereign Calculator
Dear All, I know this is nothing to do with the ZX World, but it is still Sinclair :D Does any one have a service manual, parts list, or circuit diagram for the Sinclair Sovereign Calculator? I have one where the battery acid has complete eroded some capacitors and the traces are also not too clever...

Z88 Mains Adaptor
Dear All,
Does anyone have a datasheet or circuit diagram for the Z88 Mains Adaptor?
A capacitor blew iin mine, which I have now replaced, however, there seems to be other issues, possibly with the diodes.

Re: ZX80 Video Ouput - Diagonal Lines
Good aternoon Mark,
Thank you, for the confirmation.
I shall either rip a 7805 from a spare 81 I have or go to the local electronics shop and buy one, as they cost next to nothing,
I do hope the other ICs are fine
Shall keep you posted.

Simon

Re: ZX80 Video Ouput - Diagonal Lines
Hello Mark, The Input to the 7805 Regulator is +12v and the output +8v, so I suspect that this is not working correctly, as I can also measure this voltage on the Z80 CPU. Or do you think the high voltage is due to a low load? Hello Heinz, The voltage is a Steady, even after some *fiddling*. :-) So ...

Re: ZX80 Video Ouput - Diagonal Lines
Good morning Mark, Hmm, unfortunately, I only have Access to a multi-meter, which should help with the voltage you mentioned. There is a great ZX80 repair video on YouTube, where the chap was using an oscilloscope, enabling to check the clock and video output. I shall check all the voltage drops fir...

ZX80 Video Ouput - Diagonal Lines
Dear Forum, I have just purchased a ZX80 on eBay, sold as not tested. It appears to power up and when I hook it up to Channel 36 on a normal CRT, I get strong blacl diagonal lines across the screens. I have re-seated all the ICs, however, this did not seem to make much difference. The image does app...
