Today we heard from [Richard James Howe] about his new CPU. This new 16-bit CPU is implemented in VHDL for an FPGA. The really cool thing about this CPU is that it eschews the typical program counter (PC) and replaces it with a linear-feedback shift register (LFSR). Apparently an LFSR can be implemented in hardware […]
Forth is popular on small computers because it is simple to implement, yet quite powerful. But what happens when you really need to shrink it? Well, if your target is the 6502, there’s milliForth-6502. This is a port of milliForth, which is a fork of sectorforth. The sectorforth project set the standard, implementing a Forth […]
It is hard to imagine that it has been more than four decades since two of the original designers of the Sinclair ZX Spectrum broke off to market the Jupiter Ace. [Nemanja Trifunovic] remembers the tiny computer in a recent post, and we always love to recall the old computers that used TVs for screens […]
