The case is different from the more common HC-85. But are they internal differences?

Thanks to the [Pocket Computer Museum](http://pocket.free.fr/) for this picture.\

This model is Arthur's property.

|

Even if the key were not very well aligned, the quality of the keyboard was better than that of the Spectrum.\
|
||
The keys arrangement and the functions of each key was exactly the same as those of the Spectrum but in only one colour, which was not very convenient.\
|
||
Note the reset switch located beside the 'Zero' key.

ICE Felix made several peripherals for its HC series, among them:\
|
||
• this joystick interface,\
|
||
• A Sinclair comptatible joystick,\
|
||
• A tape recorder\
|
||
• And even an optical pen.
|
||
|
||
The joystick interface is Sinclair Kempston compatible; it uses port 1 of the computer. The jack is used to plug in an optical pen.

The mecanical part of this tape recorder looks strongly "inspired" with the one from Spectrum +2.

|

text: |-
|
||
The light pen is a very simple device, containing a photodiode. It is connected to the jack of the joystick interface. When the electron beam is crossing the area of the screen where the light pen is positionend, it sends a signal to the interface, that resets bit 1 of port 191 of the HC.

|
||
In 1985, despite of the severe limitations of the political system, the Romanian computer company ICE-Felix, located in Bucharest, started to design and produce Sinclair Spectrum compatible computers.
|
||
|
||
The company was founded in 1970 and became the main computer equipments manufacturer in Romania. Several mini and microcomputers were developed, based initially on the French C.I.I. company licence.
|
||
|
||
The HC-85 was the first manufactured model. It was primarily intended for the Romanian schools and universities. As the engineers could not use the Spectrum / Feranti gate-array chip, they replaced it by a whole of logical chips that carried out exactly the same tasks.
|
||
|
||
The plastic case and the keyboard were of poor manufacture quality. However, the machine looked solid and the motherboard printed circuit was same quality level as the Western productions of the time.
