Well this is a bit of a strange situation. I have a 500+ board (Rev 8A or 8A.1). It currently has a double rom switcher (1.3 + 3.1), 1 Mb trapdoor ram expansion, indivision ecs. The board has been recapped and had some sockets replaced too as well as the battery, and plugged to a GVP A530. Great condition overall.
Now there seems to be a fault which I cant pin down When I power it up with the A530 and everything else connected, it goes into guru mode a few seconds after boot and then reboots. This cycle repeats while ever it is switched on.
Ive done the obvious which is to strip it down of all the added extras and it still happens. I get the feeling there is a short somewhere; maybe a track or two. Visually I cant see anything wrong at all, the recap work looks perfect and the sockets too.
When I plug all the extra bits into another 500+ I have, they all work fine, so its not a timing issue or anything like that. Im almost 100% sure the fault lies with the board but no idea what is causing this.
What Im after then is someone who can test all aspects of the board so I can get a repair sorted out and get her back on her feet once again.
Any experts willing to give this a go for a suitable fee ?
