I just got Vector 7 std-Gold running on a Compaq 5WV252 desktop I bought new in 2000. Not sure what my specs on this machine anymore. The motherboard is the only original part left to this little guy.
I maxed the cpu out at about 1100 mhz. Up from a stock 750 mhz. Memory is up to 768 mbs RAM. Up from stock 64 mbs. This was a WinME machine when it was new. Now it dualboots WinXP SP3 with Vector 7 Gold.
I couldn't get Vector 7 lite to install on here at all. The only other distro that worked, however buggy, was Antix 11. This computer used to run about any distro you wanted to load; but, lately, it's getting finicky. I don't know if it is going bad or if technology is passing it by.
