I'm planning to build a small 68k board as an educational project
and as something fun to do in my spare time. My background is pretty good
but I have never built anything this ambitious before. If anyone can offer
any wisdom/advice please send me mail.
Is dynamic ram too much of a hassle because of the refresh? What
memory management chip should I use to simplify my refresh etc..?
What is the easiest way to fabricate this beast? Wirewrap? Point to
point solder?
I will probably want nothing but a couple of serial ports to start out
with. What is the best uart for me to use?
Will I want to remap my ROMs to higher addresses after bootup? How
is this best achieved?
What is the fastest clock speed I should try for without creating
timing problems etc... I was thinking of 4Mhz as pretty safe.
Are there standard locations for ROM, peripherals and such that
I should use so as to be compatible?
All comments appreciated!
Billy
