| MISCELLANEOUS TECHNICAL NOTES |
|------------------------------------------------------------|
| The standard SCSI terminators terminate data bits 0-7 |
| on the SCSI bus. The SCSI-wide terminator terminates |
| data bits 8-15 (wide portion) on the bus. |
| |
| Maximum use of two SCSI connectors is recommended. |
| This means devices should be chained off connectors |
| SC1 & H1, SC1 & SC2 or SC2 & H1, but not all three. |
