The X1 Turbo Z III is the successor of the [X1 Turbo Z](/museum/sharp-x1-turbo-z-cz-880c/) and ZII. The 8bit CPU (Z80) has reached its limits here.

Like the X1 Turbo Z II, the Z III is VCCI compliant (electromagnetic emissions control) and has 128 KB RAM as standard, but does not have any remote connector for data recorder. Otherwise it is identical to the Z II.

The most famous and strong point of X1 series is the Programmable Charactor Generator(PCG).

The languages available were Hu-basic (developed by HUDSON soft), Turbo Basic and new Z-basic. The new Z basic language introduced enhanced functions (graphics and sound), but needed 128 KB RAM to operate. It was bundled with the Turbo ZII and ZIII, but Turbo Z owners had to buy it separately. An expansion memory board fitted with 64 KB RAM was then sold with the box, so Turbo Z systems could have 128 KB RAM. In fact you could add up to 256 KB RAM on this board, so Turbo Z owners could finally upgrade more easily their systems than ZII and ZIII ones.

The X68000 serie was launched one year earlier and finally, will replace the X1 serie.
