Early VLB card with OAK OTI087 chipset. This seems to a design similar to Cirrus Logic 542x series. That means 32bit memory interface with 16-bit host interface adapted to VL-Bus through a series of 74F245 bus transceivers. The same chip appears on ISA cards and also on some Weitek P9000 cards (which cannot do VGA natively). The card supports up to 2MB of DRAM using 4bit DIP26 DRAM chips.
One comment on “OAK OTI087 VLB”
This was a lot of the times the way the first VLB cards were made since anything moving to 32-bit was a massive improvement over the 16-bit version.
