Category: TRS-80 Color Computer (CoCo)
After three parts dealing with CoCo cross development, I thought I’d change direction for a bit and discuss something completely different. We’ll get back to cross development once we have something to develop. Before WWW was BBS The story so far… My first exposure to computer bulletin board systems (BBSes) was in Houston, Texas around 1981. I had become friends…
See also: Part 1 and Part 2. Previously, I presented a simple way to write 6809 assembly code on a modern computer, compile it there, then load it in to the XRoar CoCo emulator as a BASIC program. (That last bit makes much less sense when I read it back.) Today, let’s look at moving files back and forth using disk…
Updated on 1/5/2018 with more details on getting the XRoar emulator going (ROMs, xroar.conf file). See also: part 2 and part 3. In 1980, programming on a then-new Radio Shack TRS-80 Color Computer (“CoCo”) initially meant using Microsoft COLOR BASIC 1.0 with a glorious 4K of memory. More advanced programmers might have chosen to learn 6809 assembly language. With a…
The 10Liners is a contest that programmers can show off their skills creating a game using the BASIC language using only ten lines of code. Any BASIC dialect is accepted, as long as it is a line-based BASIC. The contest webpage summarizes very well the idea behind the event: The BASIC 10Liners competition is like a time journey into the…
Once again, John, Neil, and Mike Rowan are back to invade your podcatcher and green your screen with news, discussion, and Q&A about the Tandy Color Computer. This month, the Crew feature an interview with CoCo programmer Rick Adams and a tech segment on the SN76489AN audio card. Link: cococrew.org Subscribe: iTunes
Glen Hewlett has made a conversion from the Arcade version of Space Invaders, using Z80 CPU to the TRS-CoCo 6809 and we reported that a few days ago. Now he started a new project trying to port the Arcade version Pac-Man. Again the first runs on Z80, so Glen decided to write a blog about the steps he is following…
After three years of development, with several interruptions and side projects, the game Pop*Star Pilot for the CoCo3 has been released! Developed by Nick Marentes, the game consists of a colourful side-scroller in which the player controls an airplane that flies through different levels whilst popping up balloons. As well as taking care of the balloons, it is important you avoid buildings and keep…
