Wanted Andy Rea ULA

Post by Lardo Boffin »

My rebuilt zeddy (viewtopic.php?p=27533#p27533) originally had one of these but I ‘borrowed’ it to fix and sell another zeddy. I figured it wouldn’t matter as they were being regularly made at the time but of course they then stopped being made so I couldn’t get one.
So if anyone has a spare they can part with for a reasonable amount of money that would be great (I’m in the UK)!
Thanks. :D

I can supply you with an Andy Rea ULA.
It was quite some searching to find out which Andy ULA you were looking for.
These new ones are no problem.
The old one I wouldn't sell because of the very nice features it supports.
In theory, there is no difference between theory and practice. But, in practice, there is.

Thanks Paul! Didn’t realise there were multiple versions.

For clarity I had one of these although I suspect you may have already found that:-

And fitted to the Tantung 81:

Think I have killed my ROMel though. Switched it on and got a list of 0’s. Looks like I had two of the selection wires touching. Doh! Disconnected and fitted another ROM and all is good.
