4.If you are using two iSBC 016 Random Access Memory boards, you must jumper one to supply RAM memory from locations 8000H-OBFFFH and the other to supply RAM from locations OCOOOH to OFFFFH. Table F-llists these jumpers. On one board, jumper 7-6 must be connected, which enables memory at locations 8000H-OBFFFH. On the other board jumper 7-5 must be con- nected, enabling memory at addresses OCOOOH-OFFFFH. Refer to the iSBC 016 16K RAM Board Hardware Reference Manual for further information.

5.The iSBC 204 Disk Controller must be set to base address 80H and set at interrupt level 2. The base address is set by switch S2. The four switch settings of S2 are shown in Table F-l. Interrupt level 2 is the factory-wired default con- figuration. To verify interrupt level 2 operation, check for a wire jumper con- necting terminal posts 63 and 67. Table F-l lists these connections. For further information, refer to the iSBC 204 Flexible Diskette Controller Hardware Reference Manual, chapter 2.

6.The iSBC 204 Disk Controller must be the highest priority bus master. You can place the iSBC 204 in the top chassis slot with the iSBC 80/30 directly under it, or you can rewire the chassis backplane appropriately (see the iSBC 80/30 Hard- ware Reference Manual for details). The supplied cable attaches from 11 of the iSBC 204 controller to the plug on the rear of the MDS-2DS disk drive.
