Homemade Z80 COMPUTER as a accurate calculator analytic triangles with AM9511 coprocessor

This is my final homemade Z80 computer now supported by a floating point math processor (AM9511). See other photo: www.flickr.com This video shows a program I made which simulates a real scientific calculator that (as an example) solves an SSA (side-side-angle) triangle using trigonometric functions. ____________________________________ DESCRIPTION: ◦ Manufacturer: homemade by GG ◦ Model's name: Z80/AM95 8-bit NANO COMPUTER ◦ Typology: training microcomputer ◦ Number produced: 1 ◦ Country of Origin: Italy ◦ Year: 2008-2010 ◦ Style: vintage 1980's original components on perfboard ◦ Price: $0 -- (Not for sale) ◦ Ultimate aim: hobby and recreation, educational, chip-oriented retrocomputing, DIY electronics, 'Homebrewing' (designing and building of retro-styled computers) ____________________________________ SPECIFICATIONS: ◦ Processor: Z80 (MK3880P-10 8 bit CPU, ceramic purple, 2.5 MHz, -40° to +85°C) ◦ CPU Datacode: 1980 ◦ CPU Speed: 2.5MHz ◦ Co-processor: AM9511 ( C8231A 16 bit Arithmetic Processing Unit @ 2.5MHz) ◦ Co-processor capability: 16-Bit Integer, 32-Bit Integer, 32-bit Floating Point.
