Mad-Pascal meets X65

-

Mad-Pascal now has an X65 target,

and resources are in: you can attach binaries or assembler code and get a proper segmented XEX out of it. RCDATA and RCASM both work, $resource lands in proper segments, and the prolog and epilog write the header and the vector segment the way the machine expects.

So it is already usable - with two honest caveats. Keep the program under 64 KB and stick to 65C02 for now, and you can start flying. The X65 CGIA register and constant definitions are there in lib/x65.pas, with samples/x65/plasma.pas using them.

The next tempting thing is hardware multiplication: X65 has it, and teaching the compiler to use it instead of a software routine would be a nice win.

Do not expect the full library yet. RTLIB is still empty — no @putchar, no @clrscr, no graphics, no sysutils — and many units simply do not exist, because the target is still under development. Treat it as WIP, not as a fixed contract. But the groundwork is laid, and the emulator already runs Pascal.
