Is that a Solo? 2500 maybe? I had one of these as my first "real" laptop issued to me by work in 99, they let me keep it when I left in 07 because the tech had increased so rapidly. I had it for years and years until a "too fast" hard drive change snapped the connector off the bottom of the board. Sad day indeed--been on the look out for one since but they go for $100+ now days and I have plenty of other DOS era devices around so its hard to justify another one.
