le R800 n'est pas la piéce maitresse du Turbo-R , c'est le S1990 : http://en.wikipedia.org/wiki/S-1990
oui vu qu'il a déja une partie du Turbo-R intégrée le T9769C
on ne peux pas partir d'un msx2 ou d'un autre MSX genre sanyo ou sony car c'est trop différent
il faut tout ça en fait , en gras les piéces communes
256kB of main RAM (Can be expanded to 512kB or 1MB internally).
32kB BASIC/BIOS ROM and 32kB subROM (MSX-BASIC V4.0, with extra command _PAUSE to make delays in BASIC independent of the current CPU and extra commands for the PCM device (_PCMPLAY, _PCMREC)), 16kB DISK ROM, 16kB FM-BASIC ROM, 16kB KANJI BASIC.)
CPU R800 (DAR800-X0G), with 28.63630 MHz external clock and 16-bit ALU. (Can be accelerated to 40MHz by changing the crystal.) Note: the bus frequency is 7.16 MHz, however, an instruction on the R800 that takes 1 clock cycle, often takes 4 clock cycles on the Z80, so one can indeed say that the R800 runs roughly like a 28.6 MHz Z80.
CPU Z80A 3.58 MHz compatible (included in the MSX-ENGINE, see below)
TC8566AF disk controller
3.5" double sided double density (720kB) disk drive
S1990 MSX Bus-controller
T9769C MSX-ENGINE (also contains Z80A)
2 expansion ports (cartridge slots)
2 joystick connectors
2MB ROM with a Japanese text editor, a spread sheat and a sample program
MSX-Music (Yamaha YM-2413 OPLL)
PCM synthesizer 8-bit (sample rate 16kHz)
Internal microphone for the PCM unit
pause key (software in R800-mode, hardware in Z80-mode)
MSX-JE ROM with approx. 32000 characters
16kB SRAM for backup (used internally)
No cassette port (so strictly speaking, it's not an MSX!)
MSX-DOS V2.30
Reset button
RGB/CVBS (NTSC) output
110 volt main power (because it's a Japanese machine!)
A disk with a drawing programme
External microphone connector (input, mono)
6 LEDs (power, caps-lock, kana-lock, pause, CPU mode, FDD in use)
Panasonic FS-A1WSX:
64kB RAM,
128kB VRAM,
720kB 3,5" floppy disk drive,
MSX Music,
256kB JIS 1st+2nd Kanji,
Ren-Sha Turbo (autofire),
hardware pause key,
firmware (A1 Cockpit,
Word Processor with Color Print Support for Color Printers,
MSX-JE),
no cassette interface,
S-Video output,
Z80 compatible CPU built in MSX Engine (T9769x) that can be switched to from 3.58MHz to 5.38MHz via I/O port

OK ,je vais voir pour la musique
MSXien...pur et dur et toujours Supmsx
Jipe :
si tu trouve le schéma d'origine bien clair , quelqu'un d'assez fou pour faire les soudures (genre Igal )et en partant d'un 2+ Panasonic on peux en rêver 
Mode tonton flingueurs [on]
Oui, c'est pourquoi!
Qui je dois dessouder? Lol
