Picked up a bunch of these on ebay. Thought before I spend$400 I might as well see what I get with these and do some trial runs.

I have a couple questions. I want to use, if possible, theoriginal artwork provided to builders in 1973. Here is a sample of themainframe artwork that I posted before:
http://www.swtpc.com/mholley/TV_Typewriter/page_18.pdf
This is literally all I have to work with, since an originalcopy of the artwork is impossible to get now. So questions:
Is itdark enough to be usable?
If not,what would be the best way to get it darker without altering it too much? Itried just ‘paint bucketing’ black onto it in Photoshop but it seeks out theless visible grey tones and ‘thickens’ the traces, and sometimes obliteratesthe drill holes.
I’massuming using the toner transfer method I need to print the image inreverse? I assume this image was intended to be used with thepresensitized boards, thus it would be printed on clear overhead film and laidon top for exposure.
Whatwould be the best way to get it to print at the correct scale. On otherartwork I’ve seen actual scales (or ruler edges) displayed. For somereason that is not done here. I guess these would have been printed onstandard 8.5x11 pages or something as life size. But because these werescanned from pages of a magazine it’s not quite exact (I printed and comparedto my ICs). I guess I could just scale it up a percent or so at a time,but I’m thinking there must be a more scientific way.
Anythingelse to consider?
Thanks guys!!
