ASCI u68 System X

I have one of the above systems. ?I acquired it about a decade ago sans power cord. ?The power cord isn't the standard one we are used to?today.. and uses differebt polarities.. I simply didn't know enough at the time to purchase one. ?Recently though I did.. and have gotten it to power up and operate, although at times it seems to not want to do anything at all and sometimes requires a few power cycles to get going.? My question to the community is.. does anyone else put there have one of these? ?And do any of you have a manual? ?I've googled all over but its useless. ?I'm also hoping to one day find the expansion board for it that allowed it to run BASIC. ?If anyone has a line on these. ?I'd be most interested.
