Another processor module, but this time a less successful one - a board based around the Intel i960 (specifically the 80960SA / 80960SB). The i960 is one of the more challenging processors I've worked with, for a few reasons:
Of all of the modular CPU boards, this is probably the one I'm most excited to have built - it's able to boot DOS (on a "real" processor, unlike Modular CPU Platform - Update 1 !
(the 8086 board has a few functional issues …
When I was designing the PC104 Dragonball project, I wanted to design a simple (cheap!) PC104-based module to check I'd got the footprint and mechanical properties correct.
This project is based around the RTL8019AS ISA Ethernet Controller. It's mostly very similar to a very typical RTL8019 reference design, but …
I'm not certain why, but I've seen very few hobbyist projects based around the early MIPS processors.
MIPS-1 is a very interesting architecture, for a few reasons:
It's been a while since I posted an update about the modular CPU project - here's the latest status.
It can boot DOS!
Not particularly well at the moment - the 8086 board isn't functional at the moment, so I'm using the MCL86 Verilog 8086 core. This works, but …
This project is nowhere near finished, but as it's taking up a lot of my free time at the moment, I thought I'd add a quick website update in case any of the work-in-progress ideas are useful.
For a long time, I've been interested in processors, and as someone …
From time to time I like building retrocomputing projects based on old CPUs, and I decided that the 68K would be a fun challenge.
The "DragonBall" is a very interesting SoC based around a 68000, with some useful peripherals added:
Additionally …
