The different resistor values are:
D7 D6 D5 D4 D3 D2 D1 D0
v1 1K 2K2 4K7 10K 22K 39K 82K 150K
v2 1K 2K 4K 8K 16K 32K 64K 128K
Where v1 uses standard E12-series values. Whilst v2 uses less common values like 2K (which you may not have at home), and even totally non-standard values like 4K (which aren't manufactured, and need to be produced by using two 2K resistors).
'''Caution'''
Both schematics connect GND to Pin9, which works on the CPC's (unmodified) 7bit printer port, but not on (upgraded) [[8bit printer ports]], so better connect GND elsewhere.
