Sizif-512 DIY - PCB with Altera + ROM

Sizif-512 is a clone of the ZX Spectrum 48+/128/+2/+3 computer with SD card support, esxDOS, joystick socket, and other extras. It runs on a real (not emulated) Z80 processor, an AY-3-8910 sound system, and a programmable CPLD as a ULA. The Sizif-512 project is a more modern version of the Harlequin 128 project. It is the motherboard for the ZX Spectrum Neo computer.

The kit includes a PCB for self-assembly with the most difficult SMD systems soldered and programmed. Thanks to this, you do not have to solder difficult systems or have programmers for them. Assembling the system comes down to buying and soldering the remaining parts.

• CLPD Altera EPM1270T144 - soldered and programmed
• 4 x SN74CB3T3245PW - soldered
• SST39SF040 (512 kB ROM) - programmed
