- The ZX-spectrum + was the successor of the ZX-Spectrum, there was only a 48Kb model.
- The only difference compared to the standard ZX-Spectrum was that it had a new keyboard
(58 keys hard plastic, no rubber keys any more) it was a bit of an improvement, but still
not suitable for typing with10 fingers.
For entering basic programs it was all right, It took some time getting used to it. Every
key had 5 different functions (these were printed on top, above and below the keys). To
get to these functions you had to press the key or symbol-shift+key or caps-shift
symbol-shift and then the key, or caps-shift symbol-shift and then symbol-shift+key. Then
the basic command jumped on to the screen.
It sounds quit complicated and if you had never done it before it was, but after a while
you could enter basic programs faster then if you could only type with 2 fingers.
- 32 characters x 24 rows, every character was built up of a matrix from 8 by 8 pixels.
- graphics 256 x 192 pixels
- 6Kb RAM for video 768 bytes for attributes (colours, brightness, flashing)
There is a choice of 8 colours which can be made bright and flashing.
You can have 2 colours in a matrix of 8 x 8 pixels, these are called the ink and the
- expansion bus
- UHF connector, (standard it was not possible to connect it to a RGB or a composite
