![]() I use now the Battery Back Door HP19bii and it's perfect. and Advanced Logic Systems' C loneWare ALS 18C Financial C onsulrant. The Problem with the Batterydoor on the side is, it will break, if not today, then tomorrow, the Battery "push" from the inside, I had 2, both "new" and the Door broken on there own without touching them ( the Programms are lost. Not all calculator programs attempt to emulate the hand-held calculators. So while I do love the 19Bii, id rate older units > units with new battery door Plus we all know how to change clamshell batteries so it's not an issue for me. I use the calc daily so that's more important than the door which I'll only access every few years. Made with high quality Singaporean craftsmanship! I returned it and bought an older one off ebay. It was also made in Indonesia which is why I have a negative view of all Indonesian made calcs (I know, I should keep an open mind!) The keys changed from grey/taupe to black. While the door is definitely a better design, the rest of the calculator was poorly manufactured. I purchased it new online and received one of the new ones with the revised battery door. For questions about me and the origin of the museum, please see my personal page.(03-18-2015 08:51 PM)Blendama Wrote: Someone commented on the 19Bii's battery door.īack in 2003 I was starting MBA school and thought I'd treat myself to a 19Bii.
