Re: Re: K5 ROM upgrades

Amidst all the ROM happenings on the list tonight, I
opened up my K5M because I figured 18 years was a
pretty good service life for an EPROM. 

My original factory chip read in on my programmer and
the file from the group both md5sum to
26e2ecadadf6ca03c23bc3d85f37ee1e That gave me some
confidence- I used a standard TI 27C512-15 in place of
the original Hitachi. It appears to work well. RAM
Patches remained intact.

The original Hitachi HN27C512G-20 PGM 12.5V dated 8926
was labeled:

KAWAI
P020H
[K5m}

Now, I’m going to be interested in replacing the
display with something that I can see more clearly.
Cheers, [w]
