YES! I noticed a few interesting things about the TS1500 and S ZX Spectrum 16k ;
Power jack : exact same place, but not same jack.
MIC and EAR : exact same place, exact same part.
TV : TS1500's port is closer to the EAR port while Spectrum's port is far from the EAR port. And same RCA F jack "part".
Memory: exact same part eight 4116s ; TS1500's memory chips positions are widened and loosened while ZX Spectrum's memory chips positions are closer together and tighter.
Thanks.
I will post the .PDF file with Dropbox's web link here soon.
