ZX48 Clone, it lives!

Amazingly enough, the Sinclair Spectrum 48K worked first time plugged in! Took me months to build, bit by bit. The secret seems to be, take your time. Now to find other things to build for it. Maybe that sound card I’ve heard about! Another thing, I need to fit a reset button. (am aware the speaker is upside down)

Anyone been building anything to do with retro 8 bit computers?

The proof, in the pudding…

Found the photo I took of my repair, I got a blob of solder stuck on the underside of the board, and made the mistake of scratching it off (along with a track and through connection!) with my finger nail. Found a bit of bare copper wire in a cupboard, and used a bit of wire insulation to make sure it didn’t short out.

Nice one! That’s a great build!

Thanks! When you get the kit, it doesn’t look like a lot of work, but it really is. Still looking for a sound card for it.

For those of us who aren’t deep in the Spectrum scene, do you have a link to the kit? Google wasn’t very helpful (I did learn that there were many many many Russian clones back in the day, though :smiley:).

Yes, I got mine off ebay a while back. It’s the black pub version. You may need to buy a ROM separately.

Just remembered that you can buy the whole lot here;

The ROM you’ll need is £12.99, the kit is £69.99.

You can use an original 48K case (as I did), the parts needed to rebuild it are here;

Ain’t that the truth!! Still, I never dreamed that one day I’d actually build one from a kit. They just seemed like magic boxes back in the day… still are really, but now viewed through those rose tinted glasses.

Maybe a little bit Hi-tech compare to ZX, but I spend some time 1-2 years ago with Amiga 500 and copying FDD from the PC via seial cable. Great hobby, all demoscene at all. I was always impressed with demoscene creations, like music or demos in particular. How more you can optimize code and do things that even creators of these machines did not even imagined. Good Hungarian documentary:

Thank you, I’ll watch that a little later when I’m tired again. Got a few demos on the C64 and the Speccy 48. The recent C64 ones even look like Amiga demos, with the ball. The music is what I like best, am looking at alternate SIDs for the C64, and a little card for the Speccy 48.

That’s a good documentary, I didn’t really discover the demoscene until a friend got an Amiga. The reason being, that I got all the games for my Plus 4 from Boots the chemist. They had cheap games I could buy with the pocket money I had. Nobody much made demos for the Plus 4, it just didn’t have a SID. It had a TED. :confused:

I built an RC2014 with a few add-on boards, running CP/M.
Fire it up every now and then when I get tired of using a mouse :slight_smile:

That’s a really nice looking computer, it’s how I’d design one… if I could design one! May be a future project. :slight_smile:
