A forum user here has started and sent me a sample i have invited them to post it here if they like. EDIT I would like to add whoever (else) translates this should get credit where credit is due, perhaps at the bottom of each sheet "Translated by......." or the like. Just a suggestion.
I have been given the go ahead to share the translation as done so far. This is the first page of what I believe to be the "Hard Check" Pages 41-43 of the manual. Comments are welcome, but it looks pretty good to me! ================================================== ====================== ----------------------------------Page #41---------------------------------- Checker Specifications Ver.2 Model: MEGA-CD CHECKER /PART No. 610-0276 SEGA Checker Specifications Model MEGA-CD Checker Part No. 610-0276 Published: CS Product Engineering Dept.

When placing the Mega Drive into the CD Checker Test Box, please disassemble the unit and use only the internal circuit board. For information on each component, refer to the CD Checker List "610-0267". For wiring and connections, refer to the CD Checker Schematic, "610-0267". 4) Check Flow The Checker Flow (inspection procedure) can be split into two parts. The first stage handles simple signal-variation and basic functionality checks, such as short circuits in the power line, various voltages, current, frequency measurements, basic Mega Drive access, MEGA-CD internal CPU (SUBCPU) and MEGA-CD gate array (MCE), substrate-functionality checks for basic operations and electrical checks for external sections. The second stage runs two concurrent programs to conduct a detailed self-checking routine (functions check) to check the various MEGA-CD's functions through the Mega Drive unit's internal CPU (MAINCPU) and SUBCPU. In other words, short circuits in the power line, data, address and control-signal path line shorts, etc. Functionality that can lead to substrate or CD Checker damage, unresponsive states and other unexpected behaviour, is excluded from the first-stage procedures, and so the second stage includes a detail checks to isolate the problematic areas, such as which IC pin or resistor is defective.

Mega CD 2 Service Manual, Mega CD 2 Supplement and (what I call as it has no title) Mega CD2 Additional Information added. These are quite nice manual's, lots of good useful information. This finishes up all the manual's I have.
Hey guys i will be uploading the 32x service manuals and mega CD model one service manuals soon as i get them. thanks for the upload guys will help me in future repairs.
Are they different to the one's I uploaded? (link again) http://www.sega-16.com/forum/showthread.php?23228-Sega-Service-manuals-16bit
You should put all the download links in your original post here - rather than links to other forums scattered across several pages of this thread. I have been trying to follow, but still not sure if I have them all downloaded
New thread started, purely for the manual links. These are all the manuals I have done. The GG VA0 is at SMSPower and the Mega Drive and Accessories manuals are being done by someone else. Cheers Pete
Thanks help me out a lot alps made a lot of switchs for sega stuff i even found the reset switchs you can get the same rubber replacements still.
