An Eagle 1600 runs MS-DOS but is not a PC clone. C: Well I did use clone in my op. It's often used in different ways. I hadn't thought people would always revert to giving the most obvious answer to a question. Of course if you made a totally identical clone mobo of a 5150/5160, the roms would work. My question was (or should have been) given? an empty socket (as is the case on a 5150/5160 mobo, rarely anywhere else) or a means to extend that bus to accept additional roms via a plug in board, would you expect BASIC roms to work in say a Tandy 2000, AT $ T 6300, Compaq Portable (original), Zenith Z-100/120, etc. Wouldn't most of the lower level stuff be BIOS driven? ?And while there are not degrees of pregnant, there are degrees of clonage. Looser usage albeit. Did Compaq *not* seek to clone the operation of an IBM PC? From a s/w vantage, it most certainly was a clone. But I'll agree a true clone is mostly and exact one. ?Did you mean the Columbia MPC1600? I don't personally know of an Eagle 1600, unless you're referring to a little seen portable unit. But I don't follow the rest of your post--perhaps if you used shorter sentences... C: Ok. I will. Next time. Promise. No more. Then two. Words between. Periods. Period.
