Goldarn it, why has no-one built a "Spectrum-on-a-chip" yet? The
wretched C64 (spit) has had one for nigh on a squillion years!

I have a dream. A dream of cheap, modern, replacement boards for
knackered old 48ks, with built in support for SDcard and a modern TV
out!

Just one word. Emulation.

There is the ZXGate project - a complete Spectrum on an FPGA - but the
links to the source code have been broken for many moons.

http://zxgate.sourceforge.net/

But I guess it shows that someone has done it once.

Taking 'Spectrum-on-a-chip' as meaning any clone with an FPGA core:

ZX Evo: http://www.nedopc.com/zxevo/zxevo.php
Pentagon 2.666: http://pentagon.nedopc.com/info.htm
ZX-Badaloc: http://www.zxbada.bbk.org/badaloc_fpga/index.htm
Harlequin: http://www.zxdesign.info/

...although if you want any of the above in a hurry, you may have to do
some or all of the following: send money to Russia, solder it yourself,
invest in the project so that the creator can work on it full time.

Nifty stuff. Thanks for the links, everyone.

On emulation: It's not the same. It's really not. PC keyboards are
a poor match for the notrious rubber johnny keyboard of the 48k, and
the Speccy isn't just about playing games - if you're really hankering
after Outrun, it's unlikely you're going to reach for the Spec version
when the original arcade version is emullatable.

To be honest, I wonder if there isn't a market for low powered "kit"
micro-computers, particuarly those based on nostalgic faves like the
Speccy.

There isn't.

And verily, didst OwenBot <chev...@gmail.com> hastily babble thusly:

Well, there WAS that stupid little joystick thing from a few years ago that
was basically an atari joystick with a commodore 64 inside and a few games
built in...

Or am I misremembering?

Only partly. It was a Comp. Pro.

And it wasn't that stupid. If you opened it up, you could connect a
keyboard and disk drive to it. Nice little thing, actually.

Well, there is, just not "nostalgia" ones. There are plenty of hobbyist
kits built around 8 bit microcontrollers. Low powered "kit" computers
can be found all over the place. The market is about as big as it ever
was for "kit" computers.

I think this is quite cool....

I know it's a bit deverse and not really comparible to the kind of hardware
on the speccy...(cpu memory and not much else); but it still looks like fun
to experiment with.

I'd prefer if someone just found an easy way of making replacement
chips actually.

They have. The ULA was the only component you couldn't replace and
it's now been replicated on a CPLD.

The ZX is blessed with sturdy and easily sourced chips alright.
I was more talking in a general 8 bit sense I guess. What would be
well nice would be if every chip for every machine had some code to
emulate it that could be used for off-the shelf FPGA chips. Could
become a bit of a Ship of Theseus after a while I guess...
