I was pretty sure z80's were only a couple of cents...well maybe that's just how much it takes to produce them...
Why do they charge $115 for the calc, though? It was even more than the Prizm at my local Office Depot!
Hi everybody! I'm new here I'm starting to learn z80 assembly for the ti 83+. I was wondering if it would be possible to build your own calculator with a z80 microprocessor and some sort of screen similar to the ti calculators screen. Wouldn't you have to put the ti-os on it to run programs and such? If this is even possible we could probably add more memory to the home made calculator. Unless that would cause you to have to rewrite the ti os or something to support more memory. I don't know if this is just stupid or if some one has asked before. But all feedback is appreciated! (Sorry if this is dumb or impossible)

@Spyro543 Yeah I would work together with you, if you think you can and know how to build it because I want someone who would be dedicated to this and could give me their input and skills.
Also will you show this Dream Calc idea thing your talking about?
So guys I'm putting together a list of stuff I might need to make this thing. Feel free to suggest different places to buy stuff and if you think I should add anything.Z80 - http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&pa=35561&productId=35561&keyCode=WSF&CID=GMC128K flash rom - for os using rom because it would not be rewritten alotDo you guys think I should use eeprom or sd card? - http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=WM3472DKR-ND 64k ram chip - ?LCD - ? i/o chip - ?You guys are going to have to help me with this thing because I know your all super geniuses and stuff and I, no we will build this thing together so how about it? Will we build this thing for all the nerdy people who want an affordable calculator with a lot of memory!?
