mpc3000.cpp - Akai / Roger Linn MPC-3000 music workstation
Skeleton by R. Belmont
Hardware:
CPU: NEC V53 (33 MHz?)
8086-compatible CPU
8237-compatible DMA controller
8254-compatible timer
8259-compatible IRQ controller
Floppy: uPD72069
SCSI: MB89352
LCD: LC7981
Quad-UART: TE7774
Panel controller CPU: NEC uPD78C10AGQ @ 12 MHz
Sound DSP: L7A1045-L6048
DSP's wavedata bus is 16 bits wide and has 24 address bits
DMA channel 0 is SCSI, 1 is floppy, 2 is IC31 (some sort of direct-audio stream?), and 3 is the L7A1045 DSP
IRQ 3 is wire-OR of the 72069 FDC and 89352 SCSI
IRQ 4 is wire-OR of all 4 TXRDYs on the TE7774
IRQ 5 is wire-OR of RXRDY1, 2, and 3 on the TE7774
IRQ 6 is the SMPTE sync in
IRQ 7 is RXRDY4 on the TE7774
TE7774 hookups: RXD1 is MIDI IN 1, RXD2 is MIDI IN 2, RXD3 and 4 are wire-ORed to the uPD7810's TX line.
TXD1-4 are MIDI OUTs 1, 2, 3, and 4.
MPC2000XL & Classic:
CPU: NEC V53
Floppy: uPD72068
SCSI: MB89352
LCD:
Dual UART: MB89371A
(V53's 8251 is used for panel comms here)
Panel controller CPU: NEC uPD7810 @ 12 MHz
Sound DSP: L6048
MPCs on other hardware:
MPC4000:
CPU, LCD, panel controller: SA1110 StrongARM @ 176 MHz
SCSI: FAS236 (same as NCR 53C96)
IDE, UART, DMA controller: FPGA XC2S100-5TQ144C
USB Host: SL811HST
USB function controller: NET2890
DSP, MIDI: MB87L185PFVS-G-BND (gate array?)
MPC1000:
CPU, LCD, UART, panel controller, DSP: SH-3 7712 (HD6417712)
MPC500:
CPU, LCD, UART, panel controller, DSP: SH-3 7727 (HD6417727) @ 100 MHz
MPC2500:
CPU, LCD, UART, panel controller, DSP: SH-3 7727 (HD6417727) @ 160 MHz
