> Nit: It's the Pi 500+

I really want to hope the name is a nod to the Amiga 500+ (which had twice the RAM of the A500 ..)

This made me do some research and I'd say it appears so.

https://www.raspberrypi.com/news/raspberry-pi-500-and-raspbe...

> Our experiences with that programme informed the development of Raspberry Pi 400, our all-in-one PC, whose form factor (and name) harks back to the great 8-bit and 16-bit computers – the BBC Micro, Sinclair Spectrum, and Commodore Amiga – of the 1980s and 1990s.

(emphasis mine)

So the 400 name is explicitly inspired by such systems, their next one is called the 500, and the upgrade to that is called the 500+. I'd say it's a pretty safe bet that's exactly the inspiration.

One of the main differences between the ZX Spectrum and Spectrum+ was the upgraded keyboard. The original had the famous mushy rubber keys but the Spectrum+ had an injection-moulded keyboard

So with a nod to both the 500+ and Spectrum+, it's a pretty apt name.

I guess its Pi 1200 next then?

[deater]

quite possible because it's from Europe, but remember that Apple was sticking + on the end of their model names 6 years before the Amiga existed.

Acorn Archimedes 400 series, and the 500 series that followed it (in practice only the A540). The original ARM workstations.

The single board computer Pi naming scheme is based on the BBC Micro (Model A, Model B).

As for the 'plus' - Acorn A7000+ was the last of the Acorn desktop computers to be released.

There is a heavy Acorn influence with Raspberry Pi, for good reason.

Don’t forget that ARM was originally the Acorn RISC Machine.
