If it is a K6 and the motherboard has a Super Seven socket (and BIOS and chipset that supports the K6-2), the easiest upgrade would be to slap in a K6-2. Keep in mind that you will need PC100 RAM if you go with the K6-2 300 or up.

200 MHz...can't be a K6-2 as far as I know.

Also, regarding where/what to buy: I have a home-based business (part-time) and I can put together better systems for a better price and with better service (at least to home users; to business' I warn them that I am not available 9-5) than any of the big companies. And I generally have better warranties (2 or 3 years minimum on everything, some stuff longer). If you decide to go with a non-brand name, just make sure you are getting a good mainboard and good components. I prefer Asus mainboards.

Also, adding to the advice about the Intel Celeron: 333 is a good choice. If you go with 300, make sure it is a 300A. The 300 doesn't have any cache; the 300A and above does...and it is a big difference.

>First, there are several AMD processors on the market; presumably this is a K5, K6 or K6-2, probably a K6. This machine is below what I'd consider entry-level at this point; HP, COmpaq IBM and others have systems based on the AMD K6-2 266, Cyrix MII 300 and Celeron 300A, with everything but monitor for well under $1000 at retail.

>The K6 processor itself is not a problem, except for some easrly releases of the K6, it's pretty close to a Pentium MMX in terms of compatibility. It is necessary to use a BIOS that can handle the K6's slightly different identification and setup code, and the motherboard needs to supply the proper voltages 9which are not the same for all chips.) You'll need to check their motherboard to ensure that it's set up properly.

>I'd strongly advise that they reconsider if it's a K5 or K6 (the K6-2 isn't a bad chip) and look into a system based around Intel's Celeron processor. An HP Pavilion models 6355 has a Celeron 333, 64MB of RAM video, USB, 56K modem, sound, speaker, a ~6GB hard drive and 32x CD ROM drive for under $800 locally at Staples without a monitor. HP has a great rep for service, and I've installed a couple of dozen of these both at my office and at client sites; they're a piece of cake to set up (in our case, we add a 3COM 3C905B/TX 10/100Mbit NIC for ~$50 and a monitor; the machine boots and configures out of the box, recognizes the card, and with minimal selection, comes up live in our LAN environment (mixed NT/Novell environment.)
