Please Help Identify Mystery ISA Card

I just recently purchased an old Toshiba T5200/100 Laptop at a thrift store. One of the cards installed in it was an old 8-bit device of some sort. First of all, here are pictures of the card in question. http://webpages.charter.net/scarletdown/Geekworks/GW-Mystery-Card-0.JPG http://webpages.charter.net/scarletdown/Geekworks/GW-Mystery-Card-1.JPG Can anyone here help me identify what this card is, and more importantly, where I can download MS-DOS drivers for it? It is from Maynard Electronics, 1988. The large socketed chip says: WD33C93A-PL 00-08 9031 069660200102 PROTO Other markings state: Type II Controller, and Rev. -5 The FCC ID number is D8I6I2 60201. Just taking a wild guess, I suspect that this is some sort of SCSI Controller. However, I could not find it in the TH99 archives. The only match for Maynard on Driverguide is for a 16-Bit SCSI driver from Seagate. Also, I could not find any info on Seagate's site either. So, anyone here have any info on this card and possibly know where to get drivers for it?
