The images clearly show it's an Apollo1230 card with a 030/28Mhz and 4Mb Ram. Looking at it I think the HD jumper should be closed. If that won't help getting the computer stable try change the simm (the card can take simms up to 32Mb for a total of 64Mb). There's an FPU on the card (68881/28Mhz). Estimated speed improvement with such a card is roughly about 6-7times that of a normal A1200 and the FPU speed up math calculasions alot helping out with 3D games, renders and packing tools. SCSI controller is onboard (the 26pin connector is to attach a 25pin DS), speed 3.5Mb/s.
