Re: 48G(X) serial number vs. ROM version Message #5 Posted by Bo B(Sweden) on 28 Nov 2005, 3:58 p.m., in response to message #4 by tomcee
Some information about the display change ( green to black ) can be found here:
HP-48GX of black character
And about the keys: to the best of my knowledge all Singapore made HP-48 have double-shot injected keys, while the Indonesian made have painted keys. So the timeline regarding these issues is something like this:
1994-xx-yy - Change from ROM version P to R
1997-xx-yy - Manufacture moved from Singapore to Indonesia
2001-xx-yy - New "black" LCD introduced
But it really would be nice to have these dates more precise.
