One thing that's very obvious is the modern geometries in the pcb

traces all the 45 bends are perfectly symmetrical and the
corresponding corners are sharp as a knife. Boards of the day always
had a some discernible tolerance between the traces and distinct
rounding of the corners, even the 45 bends.
The traces are different, but in general that isn't a good way to
identify a vintage / replica PCB.
The cassette board is also missing the copyright and NTI logo.
There are too many specific details about this to list them all...
Is anyone
else questioning if this 'original' might instead be
one of Steve
Gabaly's
(aka 'obtronix') replicas?
That appears to be the case. The Rockwell 40 pin chip is wrong as well.
Unfortuantely, "counterfeits" doesn't appear to be in any of the categories
eBay lets you report.
