Got this at auction monday. The first 'laptop'.
99% new in the box...but it didnt work. got the SM online which has the SCM, poked, prodded, discovered no -5v supply. but it was working with no LCD. found a bad cap and a bad diode on the internal power supply, replaced with modern...wrote a Q&D to test it...
There is quite an online following for these from the past...the listserv is still working and some people put a lot of effort into a machine dwarfed in speed, memory and function with the disk drive manager inside the HDD on THIS machine....
but cool none the less. I now have a timex sinclair 1000 with RAM module, a TI 99/4A and this M100.
