thanks Michael. MAME is a great avenue for testing. The only real-world testing that is 'absolutely' necessary is to confirm that both cards work together in the same system. I removed the HFDC from my system to use it for repair purposes long ago, and never got around to putting it back in.
Oh, and not to forget your implementation of the larger Horizon RAMdisk, that will allow us to test the 'hard drive' implementation for the RAMdisk, which doesn't require a SCSI card but relies upon the common HFDC and SCSI routine framework.
