It seems to be good. I haven’t plugged in my ZXPand yet to be 100% sure but feel confident it will work. I just need not to plug in the wiznet ircchat board and ZXPand together. Not sure if that’s what killed the flash rom chip on ZXmore or not but just glad it’s back up again.

Like for all electronic parts you should be careful when plugging in cards (like ZeddyNet card or ZxPand). ESD (electrostatic discharge) can kill those components, so first discharge yourself before touching such a component.

I already killed a ZX81 by ESD (when connecting the write-enable jumper on ZxPand to reprogram my EEPROM on ZxPand) and a ZeddyNet-card, when moving it from one Zeddy to another one :(

So true Siggi!

ESD is most likely the culprit.

Thanks. I'm working on another project at the moment for work but will get back to my TS1000 in a couple of weeks or so.
