PICSimLab supports picsim microcontrollers (PIC16F84, PIC16F628, PIC16F648, PIC16F777, PIC16F877A, PIC18F452, PIC18F4520, PIC18F4550 and PIC18F4620) and simavr microcontrollers (ATMEGA328). Arduino is an open source computer hardware and software (Italian) company that designs and manufactures CPU board kits for the control of objects. A handy pocket book for RT11. GZ/80 - Zilog Z80 turbo card for Apple II computers Submitted by GG on Thu, 01/30/2020 - 09:57 The Microsoft Softcard was the first card to allow CP/M software to run on the Apple II. 44MB floppy drive?!. The table below provides the Personal Computer Drive A Pinout for either the 3 1/2 or 5 1/4 floppy drive. Interesting idea… So basically when the Z80 activates MREQ and RD, the Arduino sends it an op code as if it were reading from ROM? I have a Z80 project right now that uses EPROM and RAM in the usual configuration, but uses an Arduino as a peripheral device, so that when the Z80 activates IORQ and RD, the Arduino sends it a byte on the databus, and vice versa when the Z80 activates IORQ and WR…. A handy pocket book for RT11. The other end of the flatcable is connected to the Arduino shield and the Arduino to a modern PC with a terminal emulator. See it in YouTube:. An Z80 Dis-assembler driver for all. That said, the address lines on the bus should be continuously changing.
