asst128 needs work -- it's unclear if it has the DMA chip, f.e., but the BIOS at least displays the startup logo:
ie15 also needs work -- native keyboard is not hooked up, video emulation is a bit inaccurate, and it abuses the bitbanger.
ec1841 software is working -- f.e. the tests on "tps-2.2.14" disk are useful to find emulation bugs; at the moment the CPU test fails due to some DMA breakage).
