Hardware, Embedded Systems "As the Raspberry Pi started to ship the Sinclair ZX Spectrum turned 30 years old, and comparisons were being made between the two and their role in providing access to affordable computer hardware. Given the phenomenal advances in computing since the birth of the ZX Spectrum, I thought it might be fun to compare the Raspberry Pi with a computer that was closer to the state of the art at around that time, and to see if the Raspberry Pi could fill its shoes..."

Computing has come a long way for 30 years. If only it was possible to actually buy a RaspberryPi right now... ;)

Then I hope you don't have a wife/girlfriend like me who hours after I've come home mentions a packaged had arrived.

Mine is supposed to be delivered in the week of May 28th, according to the email from Farnell. It's just a couple of weeks after my birthday so it's going to be a great present to myself. ;)

I'm jealous! I could probably take some time off my part time job but I don't get sick or vacation time there. And my weekends off are spent with the girlfriend...but she's very accepting of my tech addiction and she's as excited as I am about the RPi.

I'm looking forward to your write-up on it!

i got kind of pissed and ordered a mele a1000 (cortex a8 allwinner a10). And I actually received it as well. Unfortunately I've only gotten far enough to build an archlinux distro with an already existing kernel. Hopefully lima releases real drivers soon enough, and it appears there's libraries available for the DSP although licensing is a question yet. It definitely has more cpu power than the rpi.

Well for me it's not about the CPU cycles, it's about giving money to a foundation that will put it towards education, and getting a nifty little device in the deal. It's also about getting a device that I can actually learn with. No offense to your purchase, it seems like a nice set top box, but I have at least a dozen ideas to use the RPi with, most of which will teach me things I don't know. If the RPi came in a flashy case with a remote and a media OS preinstalled I doubt I would bother hacking around with it.

As for the CPU's speed, I have an old WinTerm thin client with a 500MHz x86 processor that is more than enough for the projects I've used it for (print server, file server, MP3 jukebox, GPS controller, etc etc).

Though, IIRC, you also planned to use R-Pi with MAME ...that's very about CPU cycles ;p

"We currently expect to despatch your Raspberry Pi within 7 working days."
Fingers crossed.

I'm planning a home automation device, so the Pi combined with RFXtrx433 (http://rfxcom.com/transceivers.htm#12103) will be a good start ;)

It's a fun novelty to see this work.

And I've mentioned this before.

But when I look at the RPi, rather than thinking about legacy room filling mainframes running on a credit card (novel, naturally), I think more about legacy Unix workstations.

I look at an RPi and wondered why it was so difficult to replicate what we had with a NeXTStation 20 years ago.

A 25Mhz 68040 with a Postscript based display manager, built on Obj-C (which folks complained about the performance of back in the day).

The ARM CPU is roughly 50 times faster than the '040, the RPi has > 10x the memory. I/O and network is much faster.

I guess a modern desktop struggles to fit in 256M of RAM. Modern browsers are black holes of CPU, plus the added requirements of L10N and I18N. The modern compilers are CPU intensive as well, but once running, things should be good.

The browser defines most users experience on their computer more so than most any other application.

But a NeXTStation was a pretty sweet machine for the day, I think the RPi would make a nice modern "small" NS. Instead of a pizza box computer, it would be a mint tin computer.

Well, GNUstep should work perfectly fine on RPi... (though it still doesn't have a browser that really blends in - BTW calling them "black holes of CPU" isn't really fair, they do quite a lot more than WorldWideWeb/Nexus)

I/O and network is much faster

Sort of... RPi doesn't have network controller, it depends on USB adapters (Model B also, just onboard), and that's not the fastest of approaches (especially given some USB CPU overheads, and an anemic CPU of RPi)
