I have bought most of these items in unworking condition and, so far, I have fixed several of them. It is very interesting to have Service Manuals for any serious work or just if you want to understand how a plug-in or mainframe works. In current equipment, Service Manuals use to be lots less detailed, if you can find them.
I have most of the Service Manuals for these items (both in paper and in PDF) so if you need any information, just E-mail me.
If you need manuals, please, check also the Technical Manuals CD-ROM Compilation page.
