I have access to inexpensive 16550A's. These are 16550A's, NOT bug ridden 16550's. If you would like some, send a check to the address listed below. The price is $10 each including shipping via US mail. The offer is only made to locations within the continental United Stated. California residents add appropriate sales tax. !!!!! Please don't call regarding this deal. !!!! The warranty is 30 days or your money back. You must return the product to get your refund. The reason I'm selling these parts is because ANTHEM Electronics refused to give me a quantity discount on 32 parts. They wanted $20 each. So, I bought 1000 from one of their competators, and I'd like to save as many people as possible from buying them for $20 each, plus my company uses them, so everyone is happy, except possibly ANTHEM 8-). I convinced the company to allow me to do this on the basis of the goodwill it would generate for our company in the Unix community. If you have any questions PLEASE use email! DO NOT CALL!

I have a question. How might I discover whether I'd benefit from having one of those chips? I have a vanilla Zenith 386. I looked on the I/O card; the only chip that I thought might be a serial chip has the part number NS16450N. Please respond via e-mail. --- Bill {uunet|novavax}!proxftl!twwells!bill

From the 550's data sheet: The NS16550A is an improved version of the NS16450 Universal Asynchronous babble... To *benefit* from it you have to enable the fifo's, which takes either driver hacking or dropping the right stuff into I/O space and hoping your software can deal with it. What I hear is that the software out there doesn't barf if you go around it and enable the fifo's, but you get better performance with a driver that knows about it. PS: If any of the half dozen folks I've sent pre-release copies of my driver to read this, let me know how its going. -- Steve Nuchia | [...] but the machine would probably be allowed no mercy. uunet!nuchat!steve | In other words then, if a machine is expected to be (713) 334 6720 | infallible, it cannot be intelligent. - Alan Turing, 1947
