Sinclair developed the ZX Spectrum 128 (code-named Derby) in conjunction with their Spanish distributor Investrónica. Investrónica had helped adapt the ZX Spectrum+ to the Spanish market after the Spanish government introduced a special tax on all computers with 64 KB RAM or less which did not support the Spanish alphabet (including ñ) and show messages in Spanish.
The machine resembles a Sinclair Spectrum +, but has red lettering and a large heat sink on the right hand side, this was needed as the new chips and architecture produced more heat than the case could dissipate.
This was the first Spectrum that could be connected to scart or RGB monitor, the rear of the machine had this, and the PSU socket and the standard Expansion I/O, as well as the RF socket.
On the front is the Keypad socket and the leftt hand side has the RS 232, and the mic and ear ones for tape loading/saving.
Sadly the machine was only on sale for a few months before Amstrad bought the rights to the Sinclair name and IP, and the machine was altered slightly and became the Spectrum +2
Around 30,000 of these machines made it into market, and are becoming less common today.
