That, I'd pay a bit of money for, maybe as much as $50 if it's working. More likely, it's a GRiDCase and maybe worth $20 at most. If, on the other hand, it's a Convertible (2260 or 2270), you're talking real money again; I'd pay $100 for a 2270. The one that was used on the shuttle (I don't think the shuttle ever landed on the moon?) was (iirc) the GRiDPad 19xx, see my other message about those. If it turns out to be a 1535 (or other model with both the Gas Plasma screen and battery power), let Derek Peschel know; he's been looking for one for a while. (I have been trying to find one unsuccessfully for him.) Aside from the bubble memory and the magnesium case, btw, the Compass was the first of the clamshell style computers. Beat the Gavilan by half a year at least. (And no, the Gavilan wasn't the second clamshell either.) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."
