Research Machines also offered plug-in ROM Packs, containing up to 64 KB of ROM . These connected via the parallel interface allowing applications to be quickly loaded into RAM.
33.
While many cross-platform scanners provide only an SCSI interface, the Epson GT-9500 allows PC users to connect through a bi-directional parallel interface and Mac users through the SCSI interface.
34.
Also, USB allows for a transfer rate of 1 . 5 megabits per second ( Mbps ) compared with 115 kilobits per second ( Kbps ) with parallel interfaces.
35.
The serial interface board was $ 124 and the parallel interface was $ 119 . There was a special price for an 8k byte system with BASIC for $ 995.
36.
The LA30 was available with both a parallel interface ( LA30-P ) and a serial interface ( LA30-S ); however, the serial LA30 required the use of fill characters during the carriage-return.

"Compression / decompression engine for enhanced memory storage in MPEG decoder " or " Handshake minimizing serial-to-parallel interface with shift register coupled by parallel bus to address logic and control logic ."
38.
The design provided high degrees of scalability for I / O, memory, compute nodes, storage capacity, and communications; standard parallel interfaces also made it possible to port parallel applications to the machine.
39.
Even though data travels over USB more than 10 times faster than over a high-speed serial port, Visioneer's Strobe Pro scans pages somewhat slower than the Strobe scans using its high-speed parallel interface.
40.
Expected to sell at US $ 299 ( RM1, 225 ), the ScanJet 5100C scanner is HP's first flatbed scanner to connect through a parallel interface, making it easy to install as a desktop printer.
