Re: ZX81 Save

You will not regret. Ah, You will have to use a ZXpand commander. A very good tool. And if some program doesn't work or work strangely, then You should run it with SHIFT+X, if I recall, from the commander. A very useful feature. (But after using such a prog, You have to reset the ZXpand properly, k...

Re: ZX 81 questions

Hi Karl That black smudge if the K cursor. I couldn't get a decent photo but you can see the "<" part of the K. Pressing keys gives all the correct responses. It's just BLACK and about 5 times wider. I've already tuned the ZX8 modules on two Issue 3 ZX81s. But I get that on both my Issue 1s. One is ...

RAM pack manufacturer

I have a 16K Prism RAM pack which has a damaged edge connector. Opening the case to see what was needed to repair it, I found that the circuit board was marked Sinclair.

Did Prism and some of the other 3rd party sellers simply buy spare Sinclair boards and market them as their own?

Re: ZX81 Save

Thanks for the explanation Mark.

I've got the place to myself this afternoon and am going to set up the ZX81 and try to test with the old Murphy cassette recorder. Will report back how I got on.

Re: ZX 81 questions

Thanks Mark/Moggy The ROMs are the same as those in the Issue 3s so I guess these have been upgraded at some point. Yes, I did retune the ZX8 using the pots, that black bar is the best I can get to the cursor. Its possible to see part of the letter K in it but the photo doesn't show this. (I did the...

Re: ZX81 Save

Cheers guys, I'm using an old cassette player I got with a bundle of Speccy gear. I've never tried to save anything with it so maybe that would be the smart thing to do before assuming the ZX81 is bad. When you say the output is low, would I be able to hear anything using headphones. I dont even hea...

Re: ZX 81 questions

Its weird, any problems Im having seem to happen on all similar machines. This on both Issue 1s. The save problem on both Issue 3s.

That black line does have the "K" for the cursor in it, its just stretched... and black.
I take it that pre 210ULAs work OK with the ZX8 module?

ZX81 Save

When I try saving using both of my Issue 3 ZX81s the screen display is lost (ZX8 Composite module on both), then it comes back. Im assuming the loss is the data being saved. The cassette and PC capture do not record any sound. I've tried a couple of mono leads and also listened with headphones. As f...
