I had an Ohio Scientific Challenger 1p (not totally sure on the numbers and letters) which I am pretty sure had 8K static RAM for main memory and a 1K video RAM for character addressable graphics. Microsoft BASIC in ROM and a tiny hex monitor for doing assembly. https://www.pcjs.org/machines/osi/c1p/ https://www.pcjs.org/machines/osi/c1p/
