View Full Version : PCB Repair : Data East (late 80's)

25th November 2005, 09:09 AM
OK I got a few Data East boards here (Midnight Resistance, Bad Dudes, Chernov, Robocop).

They all have these same transistors marked D880. Looks to have something to do with the power. Voltage regulator?

A couple have been removed, some look damaged/dodgy.

Any ideas where to get replacements or what the modern notation for a replacement would be?

My DMM has a transistor test port, any tips on how to use?

Yeah I have a few faulty data east PCB's as well:x haven't had the time to troubleshoot them yet :cry The transistor can be replaced by 2N3055 NPN Power Transistor :D You can get them from http://www.futurlec.com/TransPower2N.shtml
I tend to get most of my electronic parts from there, they are excellent to deal with, but to make it really worthwhile you need to be ordering bulk parts:o

Suspect any 2016/2018 slim rams. There's another that I can't remember, but I have been changing a lot of these..
