Oh right, I didn’t read far enough to see there’s no DRAM support - very unusual for a 286 system (at least a PC-compatible one). That’s a big tradeoff, indeed.

- rasz 2y agoI wouldnt call it a tradeoff. Author didnt want to design memory controller, and SRAM gets him effortless 0 wait state access. Personally Im also a fan of keeping ram oldschool. I even reverse engineered a ram card for a 386 board just last week https://github.com/raszpl/386RC-16 https://github.com/raszpl/386RC-16
- moosedev 2y agoThe tradeoff would be speed and implementation simplicity against the high cost of SRAM, like you highlighted :) (Re your 386 RAM board: Nice necroproject!)
