There was also the Tandy 1100 FD/HD, a laptop which had 640 KiB of RAM and a NEC V20 running at 8 MHz apparently. I have an old Nixdorf 8810, which is almost entirely the same as a Tandy 1100 FD. Unfortunately the diskette drive (90mm 720 KiB only) is not functional and I haven't gotten around to fix it yet. (And the power supply cable is unreliable, and of course the battery is long dead.)

The NEC V20 supports 186 level instructions, though it needs special detection for this model as opposed to the typical 186 check. The typical check is shift count masking with 31, 8086/8088 and the NECs do not mask large counts in cl, the Intel 186/188 and up do mask the counts.
