Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Heck, I had to troubleshoot an ancient Heidenhain CNC today. OMG, what those guys achieved with a TMS9995 and virtually nothing for RAM/ROM. I am in awe of this thing.

No OS-BS, just incredibly efficient bare-metal programming.

The kind of stuff that only we old guys can appreciate.

The TMS9995 was hindered by it's 8 bit databus (being a 16 bit processor), similar the Intel 8088. But as long as it uses internal RAM (256bytes) only it was pretty fast.

I thought that it was the opposite; that its 16bit bus was the hinderance due to lack of peripherals and hence, IBM picked the 8088 for its 8bit bus?
