I have a few Z80 based machines that may benefit from your efforts. Do let me know if a Cambridge Z88, Amstrad NC100 (W/ PCMIA card), or even a Lazer PC4 or even-er a NEC 8401A would be amiable to your efforts. As said they all Z80 or similar & have more memory than the m100 type machines. Thanks. ds
