The machine itself is just a regular STe with 4 1MB Simms, which although expensive at the time, were quite commonplace.

The badges can be bought from eBay, so seeing one of these machine for sale is no guarantee that you are getting a ''Genuine'' developer example.

I own 2x 4160STEs, but as for provenance, they have none, since they have been assembled from parts bought from eBay and other sources. As has been said, a 4160STE is just a 520STE with 4MB RAM. You can even still buy original, NOS 4160STE case badges, so unless you have documentation that proves it to be something special, I wouldn''t take it as read that it''s anything other than an upgraded STE.

I own an origianl Atari 4160 STf Engineering Sample!

An 4160 STe never exists and is never sold in the World! Only the Type Stickers exists and were sold separately over the World!

Atari decide to produce only the Mega ST 1, 2 and 4 und the following Mega STe 1, 2 and 4!

So the 4160 STf is the only existing 1040 like ST with 4 Mb Ram on Board!
