Working !! The new board arrived and when I took the old board out I realised one of the new chips was only connected one side !!! Put them in correctly and all working and know sec fault too !

Wow. That's a lot of £s for an adaptor. I did build an Arduino shield version, which initially read eproms ok, but when I tried to burn some, they literally burned 😳. I'm guessing that I got something wrong.... An easy to build programmer for 2704 / 2708 / TMS2716 / MCM68764 / MCM68766 EPROMs – Matt's Tech Pages https://share.google/y1qxj95mkDGOs1Bk1

ROMs are about as it's emulated https://www.desertislandfruits.com/forum/index.php?/files/file/1246-nudge-double-up/ that's the had bit covered I've got the right kit to burn SRU roms and perhaps have some good spare 2708 too. Looks like I ripped a set 😁 https://www.fruitemu.co.uk/ib/topic/19629-sru-unknown-rom-set/#comment-305933

Where from? Is it guaranteed working order? Also, have you tried this.... Turn the machine off Set switch 8 on the right hand side DIL switch to ON Turn the machine on and leave it for a few minutes Turn the machine back off Set switch 8 back to OFF Turn the machine back on That will clear the RAM and if you're lucky it might boot up... Finally, make sure jumpers J1, J2 and J4 are set the same as they were on the original board.

It's resetting every time the red light comes on.

Try changing the theme at the bottom of the page to "New Default", it is a known fault that can cause that issue.
