Mandrake 10ce - I have got it to run on :
AMD Duron 1Ghz, (256Mb RAM), EPSON C40SX - no issues at all.
Intel Celeron (256Mb RAM) - had issues with the USB printer, an HP PSC 1210 - but that was not an issue with the printer nor the machine but rather with kernel 2.6.3.
IBM T20 (700GHz) - I haven't checked out the Winmodem, but I suspect it doesn't work (as always). I have an unresolved issue with Wireless networking - I have a Netgear MA401 PCMICA wireless LAN adaptor & I can't figure out if the problem is PCMCIA or Wireless in general. I have had this working just once - when I inserted the PCMCIA card during the boot sequence.
