Here is a regular SCSI card for an Apple IIe Enhanced or a IIGS. I just used it on my IIGS and it worked fine and only just slightly slower than the high speed SCSI card. This is vintage electronics and will only work in the above machines. Bid on this only if you know what it is and what the system requirements are and, of course, that you want it. I ship priority with confirmation only. You will get this pretty quick if you are within the continental US. Correction to the question asked: The ROM chip reads 341-0437-A.
