It happens... I talked about it a few blog entries before already....

Miguel's Amstrad software and compiler pages seems to be lost (I mirrored his MESCC Small C variant now) ...

http://www.s100-manuals.com

Randy McLaughlin's S-100 Manuals Site is gone also

May be somebody mirrored Randy's pages already, but I didn't found any mirror yet.
