BTW, I left CD-ROMs with Dave last weekend that have 1.3/2.x/3.x Kickstart ROMs on them, as well as a complete set of Workbench files from 1.x to 3.9.
He should already have everything he needs for WinUAE.
(He owns a system with 3.x ROMs, and has physical copies of WorkBench 2.x and 3.x - I saw them myself)
I took pictures of his SimStation, you can find them
here.
