I'm looking to purchase a ProGrappler OR a Grappler+ card where chip U10 is a 74LS374. This article from Apple claims this revision is required for use on the IIGS, which is how I intend to use it:
The ProGrappler is specifically meant for the IIGS. Regarding the Grappler, it seems there is a later vision with a reduced chip count, I'd purchase this one as well as I presume it works. I just don't want a Grappler+ where chip U10 is 74LS373 as it might not work on my IIGS. Thanks!!
