Extremely simple design -- a 8080, two joysticks and a beeper. Black and white output. A single cart with five games (Breakout, Tetris, Snake, Xonix, Choplifter). Soon in MAME smile

A previously unknown hardware variant turned up and was dumped, plus there's firmware source code. Some WIP:

Merging that code into mainline will take some doing, it's using a hacked T11 core and I don't have a clear idea how to rework it yet.

Code
# adapt to different memory layout on the KES; makes controller test pass
wpiset 4a,1,w,(wpdata==1 && w@92b==0xe),{ logerror "Hacking IOPB (xfer buffer)\n"; focus 0; temp1=920; w@(temp1+0xe)=4000; w@(temp1+0x16)=600; go }
bpset fcf76,1,{ cx=600; go }
# ACT passes transfer length 0, fix it
wpiset 4a,1,w,(wpdata==1 && b@92b==5),{ logerror "Hacking IOPB (read and verify)\n"; focus 0; temp1=920; w@(temp1+0x16)=200; go }
# firmware crashes, use a different command to fail hard disk test
wpiset 4a,1,w,(wpdata==1 && b@92b==3),{ logerror "Hacking IOPB (read id)\n"; focus 0; temp1=920; b@92b=8; go }


I suppose the next best thing is HLE, since hardware docs for actual storage controllers (iSBX clones) are missing.

Palette might be wrong and two player mode isn't working (yet)


xotmatrix decoded 2nd player's inputs (https://github.com/mamedev/mame/pull/6219) and this now works. Thanks!

LLE is mostly done now and more software runs, for example this 3rd party Sprite OS:

Great! I love seeing more of the not-quite-Apple-IIs fully working.

Bowling and hedge maze simulators on rt1715w -- these might be original, but I didn't look very hard in the CP/M game archives:
