afaik the bottom 2 pictures show engineering prototypes of the original Pulsar before the product was released.
There are also some photos where this board is shown together with a touchscreen driven controller and a keyboard. Blueprints that never made it to reality.
The TDAT16 on the first picture probably was a quite successfull product.
Based on TripleDat recording software it was an affordable way (with the A16 box) to do 16-track digital multitracking in the pre-millenium years.
The card was not developed at Creamware, but is an OEM version of the Sonorus Studio. As a sidenote the partnership ended rather unfriendly as Sonorus later accused Creamware to have stolen intellectual property...
Dunno any details but that was what Sonorus support told me on the phone as their reason why they wouldn't support any of the TDAT boards at all
