Re: restoring a Series IIx

2007-11-29 by dvdborn

Bonjour JB,

(Flamand, mais je me débroulle bien en français :-))

Thanks for the info. 
Luckely I own an EPROM writer so I'll be ordering those Eproms and I hope that the other 
components (74L...) are still easy to obtain.

Lots of work to do...

BTW, thanks for making the EPROM images available.

Cheers,
David
