I think the circuit for the 555 is correct so there is no need to change it - as you say only when we see a real board will we know the R4/R5 situation... this will then be correct or the forgers idiosyncrasy...
Your circuit diagram you posted in #192 is too low a resolution to read so I cannot work out why you have the +5v on the bottom of STEP? I think it should only go to the top of R11.
On my board and circuit I have R11 other end going to the middle PIN not the bottom one of RESET - mainly because I could only get ON-OFF-(ON) switches - this could be simulated by joining the two pads so no need to change the layout really.
Also on my vero board I had to make a physical bit of wire through the hole in the switches to make a good Physical strength - maybe the pads need to be a bit bigger to allow this or the switches will quickly break with just solder?
I am also worried that the PADS for Link wires are too small for the larger patch wiring that will be used on the Ground connections?
I am still checking again but, the other switches, CPU, Memory and LED buffer sections seem correct .
You have chosen a different set of pins to my two circuits on vero and schematic/layout on IC11 - I have checked and yours is also correct and will work, so I will update my circuit in the booklet to use those pin numbers.
