Back to topic, I think the Nintendo DS looks more like what a new MSX would look like. Only then with the bottom screen replaced by a keyboard Smile
Internally too, it has an ARM7 and an ARM9 CPU and 2D+3D graphics.

PSP's MIPS processor is no fun at all to program.

Do you think professional developers like to program for CPU's which have something 'attractive'? Do professional programmers also look back at old CPU's with a certain nostalgia? In other words, do current professional programmers love the Z80 or the 6502? Smile

You're comparing the PSP with what the new MSX should be like.
The new MSX should be fun to program, in assembly or higher languages like C or BASIC.

I don't understand what 'professional' programmers have to do with this, as they generally program in C. But ofcourse, the easier a CPU is to program, the easier it is to write optimized assembly routines for it, which even 'professional' programmers still have to do sometimes.

Which is why our new MSX will have a 28MHz R800 Wink

That would be like what... a 110MHz Z80 equivalent?

if a 3.5MHz R800 ~ 28 Mhz Z80 then 28Mhz R800 ~ 224 Mhz Z80.

I think the msx 3 should havelooked like an oversized fz-1 3do real multiplayer with two floppy drives, a hard drive a keyboard and mouse port and two joystick ports. 3do will build the msx and it will have daisy chainable controllers up to eight players.

btw, is sony combined the PSP and the Vaio Picture Book into one unit, that will be nice!

R800 is 7MHz, so theoretically 4 times faster than a Z80 at the same clock. At double the clock it's 8 times, in theory. In practice, this is only 5 to 6 times.

So a 28MHz R800 = 28 * 5 to 6 = ~150 MHz Z80
