The '''Macintosh SE/30''' was introduced on January 19, 1989, as a powerful upgrade to the original [[Macintosh SE]]. It featured a significantly enhanced CPU, the Motorola 68030 running at 16 MHz, making it one of Apple's most powerful compact Macs. The SE/30 introduced support for up to 128 MB RAM, onboard expansion via the PDS slot, and included an internal 1.44 MB "SuperDrive" floppy disk drive and optional internal SCSI hard drive. The SE/30 was popular among power users and is still highly valued by vintage computer enthusiasts.
The '''Macintosh SE/30''' was introduced on 19 January 1989: a [[Macintosh IIx]] in a compact case. It is by a wide margin the most capable of the compact Macintoshes — a 68030 with a memory management unit, a 68882 floating-point unit as standard, eight SIMM sockets, a full 32-bit processor-direct slot and the first 1.4 MB SuperDrive fitted to a compact.<ref name="lem">Low End Mac, ''Mac SE/30'' tech specs (secondary source, used for dates, prices, codenames and the 128 MB memory ceiling).</ref><ref name="ssse30">Apple Computer, ''Macintosh SE/30 Service Source'' — Specifications, Troubleshooting, Take Apart, Adjustments and Additional Procedures chapters.

== General Maintenance ==
It is also the compact most likely to arrive dead, because of the surface-mount capacitors on its logic board. '''Read [[Macintosh SE/30 General Maintenance]] before powering up a machine that has been in storage.'''

The Macintosh SE/30 consists of two main printed circuit boards: the '''Logic Board''' and '''Analog Board'''. Below are detailed schematics and the official Apple service manual for the Macintosh SE/30.

== Video: why the SE/30 is different ==
 
The screen looks like a [[Macintosh SE]] screen but the hardware behind it is not. The SE/30's logic board carries a '''separate 64 KB video display RAM''' and a separate '''8192-byte video declaration ROM''', mapped at $FE00 0000 — the address space used by expansion slot $E in the Macintosh II family. Apple calls this '''pseudo-slot video''': the built-in display pretends to be a Macintosh II video card so that the SE/30 can share the system ROM used by the other 68030 machines.<ref name="gtmfh">Apple Computer, ''Guide to the Macintosh Family Hardware'', 2nd edition, Addison-Wesley, 1990 — Chapter 12 "Displays", pp. 408–409 (pseudo-slot video, 64 KB video RAM, declaration ROM) and Chapter 5 "Memory", pp. 208–211 (SIMM rules).</ref>
 
The practical consequence: '''no main memory is reserved for the display'''. The video buffer is independent of the SIMMs, so no memory configuration is better or worse for video.

=== Sound Path ===
=== Apple service manual ===
68030 → VIA Port A (8-bit sample) — VIA Timer 1 @ 22.254 kHz toggles Port B → PWM → RC filter → LM380 → 8-ohm speaker (or rear jack).

The Macintosh SE/30 was introduced on 19 January 1989: a Macintosh IIx in a compact case. It is by a wide margin the most capable of the compact Macintoshes — a 68030 with a memory management unit, a 68882 floating-point unit as standard, eight SIMM sockets, a full 32-bit processor-direct slot and the first 1.4 MB SuperDrive fitted to a compact.[1][2]

It is also the compact most likely to arrive dead, because of the surface-mount capacitors on its logic board. Read Macintosh SE/30 General Maintenance before powering up a machine that has been in storage.

Video: why the SE/30 is different

[edit | edit source]

The screen looks like a Macintosh SE screen but the hardware behind it is not. The SE/30's logic board carries a separate 64 KB video display RAM and a separate 8192-byte video declaration ROM, mapped at $FE00 0000 — the address space used by expansion slot $E in the Macintosh II family. Apple calls this pseudo-slot video: the built-in display pretends to be a Macintosh II video card so that the SE/30 can share the system ROM used by the other 68030 machines.[3]

The practical consequence: no main memory is reserved for the display. The video buffer is independent of the SIMMs, so no memory configuration is better or worse for video.

Memory

[edit | edit source]

Eight 30-pin SIMM sockets in two banks of four, 120 ns or faster, eight chips per module, banks filled completely, larger modules in bank A. Apple's published maximum is 32 MB; 16 MB modules take it to 128 MB but were never certified by Apple. Full rules: Macintosh SE/30 Memory Upgrade Guide.[3][2][1]

Anything above 8 MB requires 32-bit addressing, which the SE/30's ROM does not provide by itself — Mode32 or an equivalent enabler is needed.[1]
