The first PC I owned was a 25MHz 486SX with 4MB RAM and a 250MB hard disk if I recall. That was in 1991 I think. Before that I was using Acorn computers from a BBC Micro in about 1983 through to the Archimedes and RiscPC. I bought a PC because I needed to run PC software. The Archimedes and RiscPC had a software PC emulator and later a hardware emulator, but it was a little slow.
Anyone here got a Raspberry Pi? Anyone here know what that is?!
It was the 25mhz 486sx I had as well Ian, but slightly before '91. The sx as you probably know referred to the floating point that allowed faster math calculation. Fantastic time.
I do know what the Pi is but have not got one. Not really seeing a need for me :-)
Just because cliches are cliches does not make them wrong. I do like walking in the rain.
75 mhz and 8 mb! Luxury lad 25 and 1 mb in my first and that was top of the range. 28mb hard drive and half a meg of video ram.
That was our first PC, and was the first time we'd seen a hard drive - before that we had an Amiga. Before than, an Acorn Electron. And before that a ZX81 with a whole 1K of memory (got to love that 16K RAM pack! ).

The sx versions of the processor had the flloating point unit disabled so the cpu was cheaper

Reason: floating not hosting!
Raspberry Pi is all about learning to program. I believe the hardware can also interface to other hardware so you can learn to program hardware controllers. You can also learn to program apps for Android once you have that OS installed on it.

There's a history of them doing that, isn't there? Wasn't the Celeron the same as a Pentium only with some of the cache disabled? I seem to recall that the first Celeron was so badly crippled by this that it was almost unusable - so Intel released a second version that had a tiny bit of cache, so as to make it tolerable.

If learning to program apps for Android is the goal, then this can be done on a regular computer. I'm sure the Raspberry Pi is intended for loftier goals that can't be accomplished on regular computers.
