Hello Witchy, I sold these things for Dick Eichorn....in Washington DC against burroughs/redacdon......did quite well with sales as a matter of fact......but that was yesterday> no it isn't a home computer by any stretch of the word.....it is a very powerful, 2nd generation 8000 CPT..what is the serial Number???should be on the inspection plate on the back or near that area...when the unit came on the Market..CPT was in the early stages of financial difficulties....that did not keep those in DC from selling the box.....If you plug the 8000 key board into the 8520 you will either get the 8520 to work or not.....it just happens that way....when we rec'vd the 8520's the tech had to try to build a complete unit from what ever parts they had in house....oh the units came in complete, they just were rushed thru production. and the end result were always marginal....the original power up.....always asked for the floppy......in my files somewhere, Knoxville, tn....where I now reside/retired ....I'll try to connect/email with one other person that is still in the DC area.....we will see what activity this produces.....what prompted my search on this is a statement from a financial organization about 120 shares of stock/in stock ownership plans that split @ 60 back when I was selling the boxes....go figure......it has been a long time but the america social security system must actually keep records of that sort of thing....I left CPT Corp for Hol Inns, spent 13 years with them....Moved into the hospitality Industry...Room safes,,,,like the EL Safe ASSa Abloy...web site www.elsafe.com or www.assaabloy.com I now do contract work for www.perma-vault.com of Warminster, PA. I,m still in the hospitality industry....work is now concentrated on the distributors....they buy more.........I"ll keep a watch for your response....it should be interesting.....Happy Holidays....
