So I bought another zeddy as spares/repairs on Ebay for a bit of tinkering with the intention of adding a composite mod and internal 16K RAM upgrade. However, when I opened it up to take a look I found that it was an early version with the stand-off board on the Z80 to rectify a ROM error as discussed here and on pictures attached:

I gather that only 20,000 of these were produced back in the day, so I guess it's quite rare now. Anyway, I fired it up with temporary connections to the composite mod and up came the K prompt with a good clear picture.

So that led me to thinking, should I leave this zeddy as is and maybe sell it on to someone looking for a rarer version and get another one to tinker with rather than potentially damaging it with my "upgrades"?

All opinions gratefully received.
