[ARC5] ARC5 Digest,

[K5MYJ]

In the 1970's there was a lot of electronics made with "FUSE LINK" proms and 
pals. These device eventually fail and the only replacements are available 
on eBay. But you need the pattern information and a programmer to burn them.

If you have the patterns the best solution is to replace them newer 
technology such as EProms or Gals.
