The Paralan SCSI expander ASIC (PAR5780) provides a conversion from single-ended SCSI to differential SCSI and vice versa, with isolation between two ports. It may also be used in a single-ended-to-single-ended mode where the intent is to act as a switch or as a regenerator of the SCSI input on one side to the other side. The Expander ASIC does not consume a SCSI address or node, making it completely transparent in a SCSI system.
We make our own SCSI chip, which we use in all our products, and we also sell this chip. The PAR5780 allows us to build single to differential SCSI Converters, SCSI Regenerators, SCSI Extenders.

Leading LED Manufacture
Light Emitting Diodes are generally classified as infrared LED's or visible LED's depending on the wavelength of the light they emit.
The abstract structure of an LED contains Epoxy resin, LED chip, LED leads, Gold bonding wire. LED chip has two electrodes; one is on the suface of the P layer and the other on that of the N layer. The LED lead contains two sections, with a LED chip on one side and a gold wire connected to the other side. Voltage will be able to be applied to P/N junction of LED chip. When a voltage is applied to the junction, a current flows through the P-N junction and light is emitted from the LED chip.

Phylon 20020421: gone?
Modem, sound and other programs for TI processors
They made the Atari Jaguar modem and seems like thats about all they were known for? Might wanna update the page that says the Phylon site is gone, there is another Phylon company named Phylon Communications or something, they also do network products as Phylon did, maybe they are the new Phylon reinvented..
