Revision as of 02:07, 14 September 2020

The SE was available in a few different hardware configurations including dual 800KB disk drives, single disk drive and a hard disk, high density disk drive.

Powered by an 8MHz Motorola 68000 processor. Typically shipped with 1MB RAM and is expandable to 4MB. Replaced by the Macintosh SE/30.

General Information

Memory

The Macintosh SE requires 150-ns (or faster) SIMMs. RAM speed is indicated by the -xx number after the manufacturer’s part number (-15 indicates a 150-ns SIMM).

Two logic boards are available for the Macintosh SE. The original board uses a solder-type resistor to identify system memory configurations; a resistor is installed in R35 for 1 MB and in R36 for 2 MB. The revised logic board uses a jumper to identify system memory. On boards with a jumper, remove it entirely for using 4MB RAM.

Expansion

Includes SE PDS expansion. Common types of upgrades include CPU accelerators, video cards for external monitors, Ethernet network adapters.

Notes

  • The SE board doesn't use the same leaky capacitors as most other Macs in the 80s and 90s, but hobbyists should be aware that the battery may still leak due to age.
  • SE/30 PDS cards cannot be used in the SE PDS slot.
  • From MacsBug or the interrupt debugger, enter "G 41D89A". (To get into the interrupt debugger, press the button on the left side of your machine closer to the back. If you're running System 7, just Shut Down your machine, then while the "you may turn off your Macintosh safely" dialog is displayed, press the button.) This brings up a slideshow displaying four bitmap pictures of the Macintosh development team. Reboot (hit the button on the left side of the machine closer to the front, with the triangle on it) to get out of the endless cycle. Also, entering "G 4188A4" into the debugger gives you a tiny "Stolen from Apple Computer" message in the upper left-hand corner of your screen.
