Which model of CoCo?
The last ones could go up to 512K and could support OS9 Level II, using a memory control device called a “GIME” chip. It would have been slightly more capable if Tandy had used Motorola’s 6829 memory mapping chip.
I had a couple different CoCos, including one marketed through Tandy. I did get OS9 level II running on it.
I have a couple of connections to those HW and SW products.
People are still supporting the CoCo, with advanced video and storage add-ons. There’s a couple of annual meetings of CoCo partisans, one of them near Chicago.
——Which model of CoCo?-—
It had to be model 1.0. It was brand new on the market from Radio Shack and was only available with 4k memory
I had no idea it is still around.
I learned to program in Basic and developed a program on it that actually ran on the model III at the office. It would input the number and length of pieces and calculate the number of 21 ‘ stock lengths of each extrusion required. It was a tremendous benefit for such a mundane calculation.
That was the end of my programming
My young son would devour the Hot Coco magazine and did all sorts of neat stuff.
