I can't find my link to whoever wanted a TI s1500. I think is was a museum. Please respond to mmcfadden(a)cmh.edu. I was diving through my local computer surplus exchange and came across the following. I had to stand on top of a fork-truck and look into a big box to examine all of these. There's goodies in those dusty boxes. TI S1500, also external expansion chassis wd900 Doesn't look like my TI explorer. TI Business Pro TI 990 with 9-track cipher tape equivalent all in 5 foot rack Tektronix 4052 I'm keeping the Tek 4052 but I want to have the surplus exchange transfer the TI S1500 to the museum. I'm taking pictures before I transfer any of these. Mike mmcfadden(a)cmh.edu
