picoZ80 on an MZ-700 Upper screen is the picoZ80, lower screen is the original Z80. Some minor tweaks needed, you get the occasional wasted T-State between multi-byte opcodes which is down to the time taken for Redcode emulation to process as it makes 3 calls (Opcode, data 1,…

NoriQ has created an easier to build version of the SharpKey and enhanced to work with the MZ-6500/MZ-5600 machines, great work, thank-you.

Sharp MZ-80A Owners I have put up the necessary details of the Kuma 40/80 col modification on my website eaw.app/kuma80 - if you don't have 80 columns this is the best way to add the functionality. Also, I have placed MicroTech CP/M and Sharp F-DOS.

The tranZPUter Fusion Project - 2 boards assembled, CPLD/FPGA/K64FX512 tested and operating - now the hard part, writing the OctoPSRAM HDL and migrating the tranZPUter SW-700 code!

What is this expansion board for the Amstrad PCW-9512? Replaces the Z80 by soldering the board on top of the original Z80, hardwiring the original Z80 BUSRQ low and provides 1.5MByte RAM and 128KB Static RAM. Also appears to use a faster Z80 (8MHz) CPU.
