 The svg uses m68000-m-3.png as background, which should be in the same directory.  Beware that inkscape uses 5+G of ram to open and display it. The svg uses m68000-m-3.png as background, which should be in the same directory.  Beware that inkscape uses 5+G of ram to open and display it.

 Note that the simulation program is essentially digital, with the side effect that relatively important things like the clock do not work. Note that the simulation program is essentially digital, with the side effect that relatively important things like the clock do not work.

 +The text version of the schematics is composed of 3 parts:
 +
 +    * Header: one line: size x, size y, size ratio w.r.t traced image
 +    * Nodes: one line with the node count followed by one line per node. A node id is its line number, starting at 0.
 +      * Node type, t=nmos enh, d=nmos depl, v=vcc, g=gnd, p=pad, c=capacitor
 +      * x position
 +      * y position
 +      * linked nets ids (t1/gate/t2 for t/d, t for v/g/p, t1/t2 for c)
 +      * w/l ratio for transistors, surface for capacitors
 +      * orientation (except for v/g)
 +      * name
 +    * Nets, one line with the node count followed by one line per net.  A net is is its line number, starting at 0.
 +      * Number of reference points in the net drawing (beware, can be 0)
 +      * x, y coordinates of each point, the id of a point is its number, starting at 0
 +      * Number of lines in the net drawing (beware, can be 0)
 +      * pid1, pid2 points ids of the start and end point of each line
 +      * Number of big dots in the net drawing (beware, can be 0)
 +      * points ids of the big dots
 +      * Name of the net, often a number

 At the center two inverters are looped to keep the value.  Two independant vertical busses a and d are used for both reading and writing.  Reading is done by letting the bus float and connecting the memory to the bus with the a ctrl or the d ctrl line.  Writing is done by locking a value first on the bus then afterwards connecting the memory bit to the bus. At the center two inverters are looped to keep the value.  Two independant vertical busses a and d are used for both reading and writing.  Reading is done by letting the bus float and connecting the memory to the bus with the a ctrl or the d ctrl line.  Writing is done by locking a value first on the bus then afterwards connecting the memory bit to the bus.
