ZX Spectrum - just finish repairing a ZX 48K
Hi,
some weeks ago i started to repair a ZX 48K. It had no image, sound or whatever.
I Started with a new IC 7805 (tension regulator), and some image appear, but a lot o squares and stripes.
I got some advice, and transistors TR4 and TR5 had to be changed, so i bought ZTX653 (TR4) and
ZRX753 (TR5), desolder the old ones, and solder the new ones, and, howwww, a nice new ZX48k.
Here is a video of the ZX48K, loading a small text that i put in the tape.

Zx is cool, i am now playing around images. i will post a video later of a photo on the screen of the zx.

The problem with colour clash on the spectrum meant only certain colours could be placed next to each other. Put the wrong colours and you get a third ghost colour between them.
This problem was easily seen in sprite based games when the player sprite moved over background graphics and would change colour. Quite annoying.
One thing that was nice owning an Amstrad CPC was that most Spectrum games were directly ported. They looked very similar but didn't have the colour issues. The only annoying thing was that developers got lazy and tended to just do Spectrum ports for the CPC. It meant the CPC abilities never looked much better than the Spectrum's, whereas then developed natively it could do much more.
I never know the Spectrum was so popular in Portugal. What were the best selling games?
