Mini80 Prototype Project Files (2013-03-23)


This article contains links to the project files for the Min80 project. The project source files and resource files are contained in a zip file and should be extracted to a work path (where you keep your other Propeller based IDE projects).


Mini80 Overview

This article introduces the Min80 project. The Mini80 project is a Zilog Z80 based CPM 2.2 computer. All the computer peripherals are emulated using a Parallax Propeller chip. The Propeller chip is used to provide a boot loader for the Z80 CPU, four CPM disk drives (uses SD card), 3 COM ports (2 are 4 wire, 1 is 2 Wire) and read access to the root folder of the files stored on the SD card. The two main constraints for the project where; a real Z80 CPU (no emulation), and keep the project as simple as possible. The first prototype uses the PropTerm project as the system terminal.

Third Release of ForthTerm Program

This release of the ForthTerm terminal program is version 2.1. The update fixes the windows COM port section problem in ForhTerm version 2.0. COM port number greater then 8 now work. A COM port selection dialog has been added to the com port settings that allows the selection of a com port from a list of com ports available on the windows computer. The list of com ports will update when USB com port devices are added or removed from the computer. The upload and download function now work over a TCP connection. If the forth system has a W5100 or W5200 ethernet device you can now update and control the MV4th16 system over a TCP connection. See the Forth examples included with MV4th16 download.

Update for Third Release (ver 0.92) of MV4th16

This download is an update to the version 0.92 (third) release. There are very few changes to the Forth implementation in this update. A number of bugs fixes and enhancements to the example source and base I/O code are included in this update. There is a Wiznet W5200 driver included with the examples. The W5100 driver was also updated. The example NTSC and VGA code examples were updated to reflect the changes to the base Forth words "ROLL" and "PICK" which were changed to use a 0 based index instead of a one based index. as of version 0.92. The base Forth dictionary was also updated to reflect the changes in the words "ROLL" and "PICK".
