What It Is

sowerbutts.com is the personal website of Will Sowerbutts, whose homepage presents him as an “Independent IT Consultant” and lists UK phone and email contact details. The main content surfaced from the site focuses on retro computing and low-level systems projects, with the centerpiece being socz80: a Z80-compatible microcomputer project for the Papilio Pro FPGA board. As a result, the site fits better under “developer tools / open-source hardware technical resources” than a conventional corporate website.

Core Features

The site is mainly built around technical documentation and project releases. The socz80 project describes hardware designs including the T80 Z80 CPU core, paged MMU, SDRAM, cache, UART, SPI, and SD card support, and documents the porting process for systems such as CP/M-2.2, MP/M-II, and UZI. The page also provides source downloads, including FPGA bitstreams, VHDL hardware source code, a ROM monitor, CP/M BIOS, MP/M XIOS, RAM disk images, and documentation files. The site also links to articles on Linux drivers, home automation, Debian usage notes, and installing Linux on a Mac Mini.

Pricing

The public technical materials and the socz80 project are released as open source, with the text explicitly mentioning GNU GPL v3. Pricing, service packages, or payment methods for consulting services are not listed; inquiries would need to be made by email or phone.

Pros and Cons

The main strength is that the content is highly technical, covering details such as FPGA design, Z80 architecture, memory management, caching, and operating system porting. It is valuable for retro computing enthusiasts and low-level embedded developers. The project is not just a high-level overview: it includes real implementation work, source code, and system images. The downsides are that the page design is dated and the information is organized more like personal notes. The latest project version appears to date back to 2014, so its maintenance status is unclear. It is also not very beginner-friendly and lacks modern project infrastructure such as issues, CI, a full documentation site, or community support.

Who It’s For

This site is best suited to FPGA hobbyists, retro computing enthusiasts, Z80/CP-M researchers, low-level Linux developers, and potential clients who want to understand the technical background of an independent IT consultant. It is not a good fit for users looking for an out-of-the-box commercial development platform, low-code tools, or enterprise-grade technical support.

Access from China

This appears to be a typical personal static website, with no obvious reliance on complex cloud services or login systems. Based on the content, it is likely directly accessible from mainland China in most cases. If access is unstable, the cause is more likely to be the network quality of an overseas personal site rather than active blocking.
