Different ROM versions HP80?

[Etienne Victoria]

Hi Harald,

Glad you got the 80 and can actually make good use of it :-)

Yes, the ROM content must be different ; maybe they had the opportunity to update it when changing design and production site.

From the samples I have, the 1247A are on the left and the 1704S on the right of the pictures.




And the board underwent a couple of changes:

1247A:




1704S:



Cheers

Etienne
