11. Another internal 32-bit parallel interface was used for the coupling the 8-bit to a 16-bit microcomputer card. 12. The WDC communicated with the host over an eight-bit-wide parallel interface in conjunction with additional control logic. 13. Initially, the " SCSI Parallel Interface " ( SPI ) was the only interface using the SCSI protocol. 14. The Stats : $ 200, 25 or 100MB cartridges, SCSI or parallel interface . ( Iomega : 800-697-8833) 15. Godbout also sold components to Processor Technology for their 4K Static RAM board and serial / parallel interface board. 16. This included scanners, tape drives, hard disks, computer networks connected directly via parallel interface , network adapters and other devices. 17. That and the bit-parallel interface and peculiar timing requirements meant the Selectric could not be directly hooked up to a modem. 18. The above sequence is just a simple implementation of a 4-bit wide parallel interface which is used to execute a SCSI transaction. 19. No longer was the consumer required to purchase an expensive SCSI card & mdash; they could simply use their built-in parallel interface . 20. The same recommendations hold for the Epson, whose parallel interface card is every bit as quirky and demands IRQ 5 or 7.
