|HP48G ROM transplanted in a HP38G|
Message #1 Posted by Thomas Chrapkiewicz on 11 Aug 2009, 12:49 p.m.
I have an application that requires HP48G functionality in a HP38G package.
My preliminary investigation shows that a simple ROM replacement in the HP38G should work.
Of course there will be keyboard issues as the HP38G package is missing a couple of keys (and this can be obviated with menu commands).
Has anyone tried this? I'm curious of any hardware issues.
Is there an existing HP38G schematic out there? I am aware of the fine HP48G schematic).
Thanks and Regards,
