Does anyone happen to know which specific Hitachi (now Renesas) H8 series microcontroller is used in the HP 10BII? And is it a packaged chip, or chip-on-board?
Thanks,
Eric

I don't know what chip is, but is a chip-on-board one for shure. I opened mine once, but I didn't have pictures :(... now my beloved Minolta X20 is blind :(((( BTW, the 10BII have the second best numeric LCD HP display ever, second only to the Voyagers'... 8-) Best regards, Nelson

Hi Eric... Damn, an H8 in a common calc? Wonder if it's flash(able) ;) Too bad I gave my 10BII to an exGF when she was buying a new house otherwise it'd be fun to 'sacrifice'. I really loved this calc's formfactor, keys, etc. Wish the LCD were brighter but it's still better than the new 33s'.

Doubtful. It's almost certainly a masked-ROM part. They

I ahve gone through 2 HP10BII calcs with their displays failing.... Anybody else with these issues. The calc does not get used for a while and when turned on segments fail.... |
