- Mac Portable / PowerBook 100 emulation
- By R. Belmont
-
- These are electrically identical 68000 machines in very different form factors.
- The Mac Portable came in a large, heavy, "luggable" form factor and didn't enjoy
- much success.
-
- The PowerBook 100 was much smaller and lighter, the result of
- Apple partnering with Sony to redesign the Portable motherboard to fit into
- a much smaller case. The PowerBook 100 pioneered the modern convention of
- having the pointing device nearest the user with the keyboard pushed back
- towards the hinge.
-
- These are sort of an intermediate step between the SE and Mac II in terms
- of functional layout: ASC and SWIM are present, but there's only 1 VIA
- (CMDμ G65SC22PE-2, not the "6523" variant normally used in ADB Macs) and an
- M50753 microcontroller "PMU" handles power management, ADB, and clock/PRAM.
-
- VIA connections:
- Port A: 8-bit bidirectional data bus to the PMU
- Port B: 0: PMU REQ
- 1: PMU ACK
- 2: VIA_TEST
- 3: MODEM
- 4: N/C
- 5: HDSEL (floppy head select)
- 6: STEREO
- 7: SCC REQ
-
- CA1: 60 Hz clock
- CA2: 1 second clock
- CB1: PMU IRQ
- CB2: SCSI IRQ
-
- PMU (M50753) connections:
- IN port: 0: PMGR_IN0
- 1: A/D FILTER
- 2: SOUND LATCH
- 3: OFF HOOK
- 4: ?
- 5: Target Disk Mode flag (0 = TDM, 1 for normal boot)
- 6: ?
- 7: ?
-
- Port 0: 0: IWM_CNTRL
- 1: N/C
- 2: HD PWR
- 3: MODEM PWR
- 4: SERIAL PWR
- 5: SOUND PWR
- 6: -5 EN
- 7: SYS_PWR
-
- Port 1: 0: N/C
- 1: AKD
- 2: STOP CLK
- 3: CHRG ON
- 4: KBD RST (resets keyboard M50740)
- 5: HICHG
- 6: RING DETECT
- 7: N/C
-
- Port 2: bi-directional data bus, connected to VIA port A
-
- Port 3: 0: RESET
- 1: SYS_RST
- 2: VIA_TEST
- 3: SOUND OFF
- 4: 1 SEC
- 5: PMINT
- 6: PMACK
- 7: PMREQ
-
- Port 4: 0: PMGR_ADB (ADB out)
