Ice-Felix
HC-91

The HC-91 is a Romanian ZX-Spectrum clone. Two versions of the HC-91 computer were manufactured by Ice-Felix.

The first one used the same case and the same keyboard as the HC-85 with coloured keys for only external difference. This version was also sold with the HC-90 name.
The second one featured a new 50 keys keyboard design (picture). Thanks to two small rectractable feet, the keyboard can be tilted.

Also, the motherboard was completely redrawn to take account of the new memory chips (only two 4464 memory chips was needed instead of 24 chips in the HC-85 version). No additional feature was added and the systems were always pure Sinclair Spectrum clones, but also CP/M compatible machines if a disk extension was used.

Despite the use of many components from Eastern Europe, one finds however several Japanese, American and even Brasilian chips.

An HC-91+ was also produced, it featured a daughter board with three interfaces: 5,25" floppy disk drives, serial RS232 and local network. (See the Read More section for more details)

production of HC-91 was stoped in 1992, when Ice-Felix lunched the HC-2000, which had same basic features as the hc-91 plus built-in floppy disc drive, and hardware upgrades.

The last HC model was a 386SX PC compatible with 1 MB ram, vga, buit-in 3.5 floppy, apox. same case as HC2000 and TV and monitor conectors. An optional 40-100 MB hard disk could be added. The computer was available a year or two and it didn't sold very well.

My HC-91 had an extended fdd 3.5" extern and came with 2x 720kB floppies - one floppy with CP/M and one floppy with games.

bai baiatu nu abera cu chestii de tipul mesterit acasa ca in afara de intrerupator si portul com e de la mama lui. asa ca lasati lumea sa descopere chestiile vechi de odinioara fara a fi indusa in eroare de timpenii.

The jack on the joystick interface is used to plug in an optical pen.
