I would rate the Milano as the best but between the 3 of them is not much difference in strength, not more than 30 maximum 50 elo. The problem was that since the Polgar I already had reached the limitations of the 8-bit processor and its limited RAM and ROM and thus no big improvements could be expected. Requests from me to H&G for more RAM and speed were declined and so they more or less forced me to find my own way and move on to a new processor instead, this against the express wish of H&G. My choice fell on the Archimedes RISC chip which later was produced by H&G after all (known as the Mephisto RISC) after a lot of juridical tug-of-war. >Today we have the discuss that Rebel can be stronger with "only" more tactic >(opinion from my chess friend, not my). Tell your friend he is wrong, nowadays there is very little to gain with SEARCH (in comp-comp) because even nowadays so-called amateur programs are real good in that. Today the top programs win their games because of better chess knowledge, this shift started 2-3 years ago. My best, Ed
