Help to save System ROM images

[Jeff$]

Does anyone have an idiots guide on how to grab System Rom images so they can be archived on Dilwyn's website, I'm looking to do it for my Thor 20 as Dilwyn lacks some of the Roms, I assume other than the memory maps the actual procedure would be the same as for a QL.

Attached a Thor 1 memory map.

On a slightly more technical note, the THOR 20 has another Rom on the daughter board with the 68020, from my faded memory, I think it may use the upper two user Rom spaces, so on the Thor 20/21 you can only have two users Roms instead of four. My memory of course may be faulty here, so wonder if anyone else knows. This would also imply its a 32k Rom (I don't really want to peel the label to check).

Is it running? - If it is - then sbytes to save it off to a file should work.

Otherwise you could read the ROM's in an eprom programmer if you have one

Thanks, SByte worked once I worked out the correct memory locations.
