There is no reason on God's green earth that the 2000 could not have come out with Zorro-I card slots. Just make them horizontal. You would have lost some convection cooling, but proper placement would have allowed the fan to draw air straight over the cards. And you would have been able to get to the cards without popping the top off and pulling the machine out of your hutch. It would have been harder to make it IBM-PC compatible, but then that's another advantage to the scheme.

The REAL 'Los Gatos' A2000 had/has Zorro-I slots and it was working!!! What
it didn't have was an IBM interface !-) The REAL A2000 was up and running
prior to the 1986 Monterey Calif., Developers Conference!

Actually, the Los Gatos A2000 prototype was along these lines. It used an A1000 main-board (*NO* enhancements, folks), *two* more PC boards to adapt from the A1000 expansion connector to the horizontal slots. It had 5 "Zorro I" slots, only 4 of which were usable unless you replaced the RAM/ROM tower with ROM's. There was some sort of arrangment whereby a ribbon cable would connect a varient of the sidecar/bridgeboard to the backplane and somehow provide a single PC slot. Externally, it looked a lot like a PC or the current A2000. I don't think it had the magical keyboard garage. In short, it had no advantage over the current design, *except* the "Zorro I" slots and would have had to retail for a much higher price to cover the cost of all the complications. It should be admitted the the Los Gatos crew wasn't all that eager to make this A2000. Their plans had apparently been for something more powerful, to be delivered at some poorly defined later date.

Actually, I don't remember any of us (I used to hang around LG a bit :-) being especially pleased with the 'Los Gatos' A2000. It was a quick and dirty machine, had 1 PC slot, and was a mechanical nightmare inside. As I recall, it was just a hack, and didn't help the machine we were actually interested in doing (remember Ranger ?) a bit. >BTW I expect Commodore to anounce a NEW user iconic interface to replace >Intuition ... GEM! :-| > >Hans no, instead I think we'll announce CAOS. :-) Talk about mixed emotions on the part of the developer community. :-) Tripos actually has been very educational. I've read the CAOS specs, and even used the prototype (on a Sage micro). AmigaDOS does a number of things better than that would have. I think that we could design a killer DOS at this point. Maybe someday; ie 2.0 cause it would break everybody in existence.

> [grr @ cbmvax] > [description of totally hacked up A2000 prototype at Los Gatos.] Hmmm. I would like to point out that a totally hacked up design produced under duress can't be considered proof that the concept is wrong. You shouldn't need more than 2 PC boards: (1) Amiga motherboard (like the 500, but with the 86-pin card edge at the back). (2) pure slot board, with an 86-pin slot and <n> Zorro slots. The motherboard plugs into the 86-pin "slot zero". On the other hand, this experience would have turned anyone off. So, where's my cheap Zorro-2 box for the A-1000 that doesn't force me to raise my monitor Yet Another Inch Or So? -- -- Peter da Silva `-_-' ...!hoptoad!academ!uhnix1!sugar!peter -- Disclaimer: These U aren't mere opinions... these are *values*.
