A popular system for hobbyists due to the compact size and expansion capabilities. The SE/30 is powered by a Motorola 68030 at 16MHz with FPU. The system is known to support up to 128MB memory, though you will either need a 32-bit clean ROM or run with 32-bit addressing enabled in the software side.
Expansion
There is a single "SE/30 PDS" expansion port, though you are able to get creative with PDS adapters in order to fit multiple expansion cards inside the chassis. Ethernet is probably one of the most popular options, along with CPU accelerators.
Troubleshooting
Jittery Video
Description: This common problem is not mentioned on the RMS webpage. It's usually caused by problems in the 4 pin connector (marked "P5" on the analog card) interface between the analog card and the CRT yoke. One or more pins in the analog card connector develop bad solder joints. A bad solder joint can cause excessive heating which causes heat corrosion in the associated pins within the 2 connectors. The heat corrosion will cause discoloration of the white connector shells.
Repair:
- Verify that the lug of the black/white ground wire from the CRT neck video card is firmly screwed down.
- If it is loose, tighten the screw and retest before doing following steps.
- On analog card, remove old solder from all 4 pin connections and resolder all 4 pins.
- If there is connector discoloration: Identify which pin pair is closest to discoloration. Scrape down the male pin with sharp pointed xacto knife blade. Use tweezers or needle nose pliars to compress the female pin so that has tighter grip on male pin.
