My I/O card currently has one serial port installed with sockets available for another. I would like to leave COM1 alone and install a 16550 AFN in COM2. My problem is that I cannot find anyone willing to sell me the UART chip alone. Also, there are two additional small ICs which need to be installed for the second serial port. Any ideas on which ICs I need there? By the way, I have called WD and they could only offer me the names of distributors selling the chip in large quantities. AdThanksVance. Brian young@agsm.ucla.edu

I'm sure other places sell it--it was the first catalog I grabbed. The two small chips are probably 1488 and 1489 RS-232 drivers. They are very cheap and are available at Radio Shack. -- Jay S.

Believe it or not, I've known a Radio Shack or two to carry UARTS _in stock_! Give it a try--they might even be able to order one for you... -- +-----------------------------------------------------------------------------+ ! Adam Goldberg ! * ! "It's simple!

Try Jameco Electronics in California (Sorry, don't have their number
handy). We buy them in quantities of 1 and 2 all the time. Last time
I checked, the price was $17.50.
