I have a large lot of linear slides, some bare with trucks, some fully mounted with belt drives. Anywhere from 36" to 75". Typically, they are NSK LS20 slides. Have eight fully mounted slides with ball screws and stages. Have several VEXTA 5 phase drivers as well.
Also have a rare IBM PS2 486DX computer running DOS 6.0 and a Camelot driver control board with interface to the computer.
