Along the same note, I am hoping someone can help me with several questions
relating to 386sx vs. 386dx architectures.

1. I have a DTK 386sx (ppm-1630 is the technical name) with 2 megs of 100
ns drams. ?) Are these memory chips the same as that used in 386dx chips?

2. I have looked at the DTK 33 Mhz system featured on page 333 (aprox.)
of the latest Byte, and it says that its 64K cache is capable of 
maintaining zero-wait states with 100 nanosecond DRAMS. Since the 
boards are made by the same people, could I use them if I decide to
move to 33 Mhz? It claims 8.17 MIPS. The fastest I have heard of is
the Mitac with a claimed 8.31 MIPS. Everex has 8.2.

3. Does anyone know of any 486 boards with 100 nsec DRAMS?

4. When I upgrade, that is, change mother boards, I would be getting
the same performance as building the system from scratch, right? By
this I mean simply buying a 33 Mhz DTK from a shop with the same
componentry I am using in my present machine.

Thanks so much. Please reply by e-mail so as not to waste net bandwidth,
unless you feel posting will benefit others. Oh yes, what experiences
(if any) have you had with DTK products? Good? Bad? So so?
