Anyone familiar with strange transistor. capacitor and these IC markings
such as
"X2 080" ,"X8 761" ,"TL 761" (not opto) ,"X8 082" ,"X6 081" ,"X6 082" ,
V4007D (not CMOS 4000)

Found in an old VEB Kombinat Mikroelektronik databook:

B080D = TL080
B081D = TL081
B082D = TL082
B761D = TAA761
V4007D = CD4007UBE
