There’s a scanned/printed version of Up Front that you can buy from The Wargame Vault here:

I desperately wanted a copy of the game, but couldn’t justify the $125 price tag on the second hand market. I was directed towards this and decided to take the plunge. I couldn’t find a lot of info about this version so decided to show you what this product looks like.

Grant posted a review of this great game in December 2016. You can read that here.
