Show HN: MacProxy Plus – Surf the Modern Web on Vintage Computers

12 hours ago (github.com)

I created an enhanced fork of the popular MacProxy project called MacProxy Plus, which makes it possible to browse the modern web on vintage hardware. You run MPP on a machine on your local network and configure the Mac (or other vintage computer) to use it as a proxy server. MPP converts HTTPS to HTTP, strips out CSS, JavaScript, and other tags the Mac's browser doesn't recognize, then serves super-simplified HTML that actually loads pretty fast on the nearly 40 year old machine. Custom handling is enabled by "extensions" (individual python scripts) which intercept requests for given domains (like chatgpt.com) and return simple HTML interfaces. Current extensions include Weather, ChatGPT, Anthropic Claude, Wikipedia, Reddit, Hackaday, WayBack Machine, Web Simulator, and (not) YouTube. Though this solution was developed with early Macs in mind, it should also work to get many other vintage computers online.

> Type a URL that doesn't exist into the address bar, and Anthropic's Claude 3.5 Sonnet will interpret the domain and any query parameters to generate an imagined version of that page on the fly. Each HTTP request is serialized and sent to the AI, along with the full HTML of the last 3 pages you visited, allowing you to explore a vast, interconnected, alternate reality Internet where the only limit is your imagination.

I want to try this.

Honestly this sounds like a pretty great way to experience the modern web on modern computers too.

Really nice work. I like the idea of site-specific extensions, and think that's the only way to do this and keep your sanity.

This seems like it'd pair really well with FrogFind.

Oh this looks perfect! I kind of intended to make something like this, but now I don't have to. Looking forward to replacing my macproxy with this to try it out :)

How do you configure System 6 or 7 to use a proxy?

  • There are ways to do this transparently if you control the machine doing NAT for the classic computer. Doing things that way used to be more common before https became the default for most sites, because nowadays you'd have to install TLS certificates on each client to not constantly get errors. However, if you're also proxying https to http, then no worries!

    I should update my transparent proxy how-to to be used with MacProxy Plus...

  • Most Classic Macs didn't have an RJ45 jack(for Ethernet) in the first place. Proxy config menus were a lot more common and accessible back then as well.

  • The browser I'm using (MacWeb 2.0) has its own proxy config (you can see it in the demonstration video around 3:27), but you can also enable a proxy at the system level using Internet Config (click Firewalls, check "Use HTTP Proxy", then enter the server address and port in the text field).

  • It's been a while, but from what I recall with early Macs apps like mail clients and browsers would have their own proxy settings rather than any system-wide setting, so you'd set the proxy in Netscape (or whatever).

Oh wow I saw this on reddit the other day. Now to find an affordable vintage mac.

  • Random old Macs are still like $80 on eBay if you don't need a specific model, they aren't all that expensive yet.

  • If you're patient (and willing to do some repair work) you can sometimes find reasonably priced fixer-uppers on eBay.
