I don't know where they get that hogwash about "dueling systems"; C64 and C128 mode are different memory management modes for the same CPU, and the Z80 is very well-behaved. The CP/M on-board is CP/M Plus (CP/M 3.0 to DRI fans), and DRI supports it even less than Commodore does these days. Not to worry: it was designed to be compatible with the KayPro, Osborne, and Epson CP/M machines (which it is) and most CP/M user groups either have a C128 CP/M library or have converted their old stuff to take advantage of the C128's extra features (colour, etc., you must understand, was NOT part of the CP/M standard!). Since I did some work on PaperClip II and III for the C128 (and 64), I probably won't be sued too badly for telling you that the C128 is more reliable than The Consultant (but don't use Consultant 128 - that's even less reliable than Consultant 64, depending on which week yours was manufactured in). About the worst problem with the C64 was its underpowered power supply - the C128 comes with a nice switching supply (the worst trouble I ever had with one of them was opening it to get at a burned-out fuse from a faulty cartridge).

Solution: take 'em outa their cases (they work fine & you can plug your RGB monitor in for crisp 80-column pictures! -- Geoffrey Welsh - via FidoNet node 1:221/162 UUCP: ...!watmath!isishq!Geoffrey.Welsh Internet: Geoffrey.Welsh@isishq.FIDONET.ORG
