Macintosh SE/30

thumb
The Macintosh SE/30 was an updated version of the Macintosh SE that was released by Apple Computer on January 19, 1989.
==Features==
The SE/30 featured a 16 MHz Motorola 68030 processor and a 40 or 80 MB hard drive. It supported System 6.0.3 to Mac OS 7.5.5. The processor direct slot was updated to a 68030 version that could share some expansion cards designed for the Macintosh IIci and later, as long as they fit within the physical constraints of the SE/30's compact Mac design.The SE/30 Is the Perfect Mac by Daniel Knight, Low End Mac. 2002-04-01.Mac IIci, Low End Mac. 1989-09-20.
==Legacy issues==
Due to shipping with "32-bit dirty" ROMs, the SE/30 could originally only address up to 8 MB of physical RAM, regardless of how much was installed. Installing a software patch called MODE32 (or replacing the original ROM with a "32-bit clean" version) allowed it to support up to 128 MB of RAM (and system software versions up to Mac OS 8.1 with a new ROM).Mac SE/30 with Upgraded ROM, Big Mess o' Wires.

===Capacitor leakage===
Over time, the s will decay and leak, causing problems such as horizontal stripes on the screen. It can be fixed by cleaning the three circuit boards and replacing the capacitors, and maybe replacing the exploded clock battery as well.Replacing leaky capacitors in a Macintosh SE/30: this time with modern SMD ones by Terry Stewart, Webzone for Classic Computers. 2015-04-27.
===Display upgrades===
Although the hardware of the SE/30 did not support it, the built-in monitor supported grayscale display. Third-party video cards for the SE/30 added support for external color monitors or grayscale display on the built-in monitor.Macintosh SE/30 DiiMO030/Xceed Grayscale by Risata, YouTube. 2013-05-28.
