Floorboard - which one to use after EPROM upgrade

[audio06]

My original POD has been in store for years due to my travelling

Above the socket for the floorboard there is no writing.

If I press MANUAL when turning on the POD is says POD 2.0

so  I must have put in a new EPROM - inside it has a label "2.3" 

 

But I now realise I have made it not compatible with my floorboard :(

 

1) What pedal board will work with this original POD that has 2.3 EPROM upgrade?

2) Are there any original EPROMs anywhere?

 

Thanks
