This has 1 MiB flash, 256 KiB RAM, 120 MHz clock speed, an Ethernet MAC and an external bus interface (so I could have more colours via a resistor DAC). Even 80 column mode should work. But is it too much?

256 KiB RAM would let you emulate a Z80 and run Z80 software for the Commodore 128. It also lets you run a really old version of MS-DOS (https://forum.winworldpc.com/discussion/8288/minimum-ram-for-ibm-pc-dos says MS-DOS 3.3 will run in 96 KiB). The original Macintosh only had 128 KiB of RAM (but the screen was 512x342, so at 400x300 we'd be missing a chunk off the edge). The 6809 based TRS-80 CoCo series went up to 64 KiB.

Plus Ethernet would be fun. Could we write a Monotron 128K Twitter client, using HTTPS?
