Put pullup resistors on the rom strobes.
Hmmmm... should switch to just gates.
Also fix the polarity of the rom address lines.
Missed the PNP transistor spice model
The bss84 model I was using appeared to have unrealistically high on
resistance.  Replace with another model (Zetex '00) that appears more
realistic.
The transistors I am actually using have superior characteristics....
Uh, we need all 8 bits of the instruction...
The very first simulation test script.
A-to-alu had wrong polarity; fix it.
Name some nets
Fix the priorities of the carry strobes.
cs# needs a complemantory driver.
Shuffle things around in prep for adding vk#.
Strobe the register to V connection.
Add some more signal names.
Adjust some labels.
The flags were a bit messed up...
dlatch doesn't need a BJT.
Tweak...
First cut of binary-level simulation.
Make the spice checker more configurable.
Update notes.
Move test sources into subdir
