Paint Shop Pro's attempt at rendering it is at:

in a much-reduced 697x606 form (~ 100KB transfer)
The default render was four times that size (pixel-wise) and chews up 14MB on
disk in PSP's own format.

Doesn't mean anything to me, but it might be familar to you.

I think I still have a pile of 6809s somewhere...
