EMF Emulators
Space Invaders
The Space Invaders arcade machine used an 8080 processor, with custom hardware for 16-bit shifting, and for sound. The 8080 is binary compatible with the Zilog Z80.
Dragon 32
A well-specced Welsh computer with a 6809e processor and 16K MicroSoft BASIC, transformed into a quirky "also-ran" by it's inclusion of an MC6847 graphics chip.
Sinclair ZX80
The first of the ground-breaking Sinclair machines, whose sharp corners let wannabe programmers cut their teeth.
Sinclair ZX81
The breakthrough Sinclair machine, which ensured their legacy would continue and not flicker.
Sinclair ZX Spectrum (WIP)
A machine which founded an entire industry, within the UK. Not just for gaming software and novel hardware, but it gave birth to a million new programmers.
Jupiter Cantab - Jupiter Ace
It literally inherits the ethos of the ZX81, despite taking a sharp left turn by using the Forth language instead of BASIC.
Elliott 903
Made in 1965, the Elliott 903 was the civilian successor to the 920B computer, with an 18-bit processor and 8192 words of storage.
(Built using the EMF framework, but not the builder)
Chip 8
Created in the 1970s, Chip-8 is one of the first virtual machines, and still a machine that has more emulators than it does software.
Cosmac VIP
This is a fractionally enhanced Chip 8 machine, with a larger display and additional instructions.
Megaprocessor
The rarest of the machines, since only one exists! It's a room-sized machine built by James Newman and housed in the Museum of Computing History, in Cambridge, England.
