How do I run TRS-OS?

If you want to run TRS-OS, I will assume you are a developer, experimenter, programmer or other enthusiast.

I welcome everyone to this project. With your support this could continue its evelution into a 21st century 8-bit operating system.

What you need;

Zilog eZ80F91 or eZ80F92 Acclaim development board from Zilog using Zilog Development System (ZDS). This allows you to load and manipulate memory as well as compile assembly modules..

Other eZ80f91/f92 based devices whereby you can load and run programs starting at 0000h.

TRS-OS and its guest TRSDOS must run from RAM, not flash.

You will need approximately first 800k RAM starting at 0000h to be available and loadable with core image file. This file will contain both OS and two 180k drives (similar to Model 4 with keyboard, screen, printer, storage drives).

You will need ANSI terminal or HyperTerminal to connect to development board and use for video & keyboard. Project is desgned around ADDS25 terminal standard. Paid version of Hyperterm has this opton as I understand. I use Tera Term,

You must be able to start execution at location 0000h.

If you have a device in mind we can discuss specific hardware requirements and/or needed changes.

Happily I now support Circle M Systems & recently added AGON platforms to our growing family.
