Not all of them. (-; Even inside the same standard we may find some "wildderness". An example: japanese computers that has external devices to turn off the drive. You will say this is not defined on standard? Well, once there is a variable to do it on the higher memory, it should be used. >> MSX RedBook.

The Technical Handbook was out a loooooooooooooooooong time after MSX1 was release, AFAIK. >> TR standard is defined in a japanese-only book that I don't even know >> the name. >MSX Turbo R Technical Databook? Maybe, but it's in japanese! (-; Ademir has one of them. >> The MSX and MSX2 standard defines Cassete. MSX2+ I don't know... but >> TR standard not even mention cassete. >Which means they are not MSX compatible. No, they are MSX2+ and TR compatible. They still being from MSX family. (-; It's just like someone said about PC (about the Basic ROM). Moreover, you always can add the cassete port using an external hardware (if Padial did one to add a Keyboard, it's possible to add a cassete). It'd be out of the standard if MSXTR had defined something else in the place of the Cassete Port. >> Note that MSX2 *is not* MSX. MSX2+ is not MSX nor MSX2.

AFAIK so is MSX2+, unless it lacks cassette >port. Not even the palete may be the same from MSX1 -> MSX2. This do not affect the game play, but it's weird and out of MSX standard... (-; BTW, the V9938 has support for lightpen, V9958 has not (they cut it off so it was possible to add horizontal scroll...) Another incompatibility issue? Sure! The MSX system is full of incompatibilities... (-; And I'm not talking of programs... Hardware.

Talking only "MSX" will reffer to MSX (1.0) standard. >Which is the basic standard, with which all standards above should be >compatible. So, if a game will be made for "MSX", it should run on MSX1 32Kb also. ----- Abra�OS/2, Daniel Caetano ([EMAIL PROTECTED]) /| | | |\ \| ___ |/ OS/2 Sites: http://www.quasarbbs.com/daniel/ \/ ----- \/ http://www.geocities.com/SiliconValley/8752/os2hp/os2index.html | | MSX Sites: http://www.fudeba.cjb.net/ -- -- Drawings: http://www.djgallery.tsx.org/ ...Programar e' a arte de organizar zeros e uns de forma que eles produzam trabalho util! **** MSX Mailinglist.
