This is the case for the april early birds from what I saw last year. As the season progresses (MIT is every month) the mix changes. < He also had an 11/23 he wanted to sell for $100 and _wouldn't_ < budge. He told me they were 'classic' computers and could If it were an 11/20 or 11/05 it's collectable. Numb is correct. 11/23s are common as house flies and though they are very classic and somewhat desireable for pdp-11 hackers he's out of his mind. Last year there was someone there doing same and I ended up taking it home for free as he couldn't bring it back. Now consider this he was offering an 11/23 complete with RX02 and 2meg memory, plenty of serial IO and TWO complete copies of RT-11v5, two sets of diagnostics disks and two RT11 doc sets. If he parted it out and sold it to one of the used DEC resellers he might get 100$ for the peices total. <PS - I would have paid up to ~$20 for the 11/23, but $100????? thats about right IF it's at least a complete CPU/mem/io/disk! With some software and known operating $50 may not be out of line. more than that it better be pristine, FULL COMPLETE DOCS and actually running. Allison
