Wanted - higher quality 505 schematic scan

Post by **dave** » Mon Apr 09, 2012 10:03 pm

Hi all,

I can't recall who gave me the 505 schematics I have in the archive. That scan was made way back when bandwidth was expensive, scanners were slow and tedious, and disk space was a precious resource.

Of course all that has changed by now. Would anybody with a set of original 505 schematics be willing to make a fresh scan using a 300 x 300 grayscale setting on a modern scanner? I'd be happy to turn those into a PDF if necessary. Or, if you already have such a scan, and are willing to let me use it for the archive--fully attributed--even better! Thanks in advance!

Dave

Also, high quality 540 / 542 rev B scans would be most welcome.

Both have been scanned at 600dpi 8-bit greyscale, jpg. I'm uploading them now. These are the raw pages from my binder with a few of my handwritten notes. If you want to wait I will clean them up and make PDF's, or you can use them as-is if you have the space or there is demand.

Hi Steve,

The 540B and 542B scans are beautiful. I will have no problem turning them into PDF's.

Best regards,

Dave

I also have 527 and 502 schematics which I can do the same way if needed.

I have uploaded the Omega Science OSI dealer price list for Sept 1980 in PDF format. This is the place I bought my C4P... (you can see the invoice on my web page

)

I have uploaded the OSI Disk and Cassette software handout in PDF format 600dpi (since the text is quite small).
