Around Apple 2 personal computer era

1979 – On my final year at Singapore Polytechnic, I decided to build my own computer system.
Based on S-100 architecture and using a popular CPU at that time – Z80.

Data input via mechanical ON – OFF switch and powered by a 10-ampere A.C. Transformer.

My S-100 Bus mini-computer (before IBM Personal Compter era)

 

Receipt printer modified as PC Printer

 

Mechanical Keyboard assembed with two joy sticks for games

 

12″ green monochrome monitor as PC screen

 

S-100 Boards build from scratch (CPU, I/O controller, RAM and Power supply boards)
