A2000 Rev 4.4 schematics?
Hi all,
In my adventures in repairing an A2000 rev 4.4, I haven't found any schematics for my revision. Using rev 6 has been fine, but I need to take a look at the board area and it's quite different. I thought these schematics weren't on the net, but then I saw them in this video: [ Show youtube player ] and it seems they're clearly out there somewhere... Does anyone have a link? EDIT: I used more creative googling and I found the schematics for 4.0, which is much closer to my board than rev 6. Link is http://www.retro-commodore.eu/downlo..._Main_Unit.pdf but it gave me a 404, so I used the torrent download available in the same page (http://www.retro-commodore.eu/amiga-...=506&width=700). If for some reason that doesn't work either, and you're stuck without schematics like me, send me a PM Last edited by GoodCrossing; 13 September 2021 at 01:09. Reason: Found it! |

try the Amiga 2000 Service and User Manual available as a PDF from https://www.opweb.de/english/company...re/Amiga_A2000
It has schematics for both the A2000 and B2000 versions as part of its appendixes. A similar manual is at: https://usermanual.wiki/Document/Com....981032141.pdf For Revision 4.4 specific hires pictures also see https://bigbookofamigahardware.com/b...uct.aspx?id=17 The amiga hardware database has a summary of the changes introduced by each motherboard revision, see http://amiga.resource.cx/mod/a2000.html The 1987 manual may be more relevant https://web.archive.org/web/20120613...anual_1987.pdf Last edited by jlin_au; 13 September 2021 at 04:46.

I had seen those schematics, unfortunately, none depicted the 32-chip RAM configuration found in the Amiga 2000 Rev 4.x. The manual I linked in my edit does include them, however, and so it's been really useful.

Based on the mentioned source from GoodCrossing I was able to find the pdf.
I have extracted the relevant pages: https://pdfhost.io/v/NqVKWqBpX_Commo...v4_Schematics_ Hope this will help. |

Thank you for the link I've added the PDF to Turran's FTP in http://ftp2.grandis.nu/turran/FTP/Co...uals/Hardware/ as 'A2000CR_Rev4_Schematics.pdf' (pdfhost.io seems to be a bit slow)
