I recently had an email conversation with Ralf Baechle <ralf(a)linux-mips.org> regarding some manuals he'd scanned: Both. The ones I scanned myself are the R6000 and R8000 manuals - extremly rare documents. I managed to get hold of them while still working for SGI and only recently got permission from MIPS Technologies to publish the manuals. The two manuals would be the R6000 and R8000 manuals. They're available via ftp on bacchus.net.dhis.org:/pub/mips/ I also scanned manuals for the WD33C93 and WD33C95 SCSI chips. Those however I don't have permission to publish, so they're not on my ftp server. And of course a whole bunch more that I downloaded from random places on the net over the past decade ... I btw convert my scans into PDF files for which nice reader software is available. [...] I found proper 68000, 68020, 68030, 68040 and 68060 manuals on the net, that is "real" pdf files, not scans. These are the URLs: http://www.freescale.com/files/archives/doc/ref_manual/M68000PRM.pdf http://www.freescale.com/files/archives/doc/ref_manual/M68000PRMER.txt http://bellota.ele.uva.es/~jesus/datasheets/motorola/68000UM.pdf http://dac.escet.urjc.es/docencia/Micros/DataSheet/CPU/motorola/68020um.pdf http://dac.escet.urjc.es/docencia/Micros/DataSheet/CPU/motorola/68060um.pdf http://dac.escet.urjc.es/docencia/Micros/DataSheet/CPU/motorola/060d.pdf http://www.tornado.nsk.ru/support/docs/68030UM.pdf http://www.tornado.nsk.ru/support/docs/68040um.pdf And this one is scanned but given the age I wasn't exactly expecting a Postscript or PDF file ... http://bellota.ele.uva.es/~jesus/datasheets/motorola/6809.pdf Ralf
