**82420TX/ZX PCIset (for 486) TX (Saturn), ZX (Saturn II) c:Nov92
***Notes:...
***Info:...
***Versions:...
***Configurations:
Original TX version (Saturn):
ISA:
82424TX + 82423TX + 82378IB c:nov92
82424TX + 82423TX + 82378ZB c:oct93*
EISA:
82424TX + 82423TX + 82375EB + 82374EB c:mar93
Updated ZX version (Saturn II):
ISA:
82424ZX + 82423TX + 82378IB c:oct93*
82424ZX + 82423TX + 82378ZB c:oct93
EISA:
82424ZX + 82423TX + 82375EB + 82374EB c:oct93
82424ZX + 82423TX + 82375SB + 82374SB c:94
Updated ZX version (Saturn II-50):
ISA:
82424ZX-50 + 82423TX + 82378IB c:oct93*
82424ZX-50 + 82423TX + 82378ZB c:oct93
EISA:
82424ZX-50 + 82423TX + 82375EB + 82374EB c:oct93
82424ZX-50 + 82423TX + 82375SB + 82374SB c:94
>* These configurations are unlikely as the 82378ZB variant was
introduced at the same time as the Saturn II 82424ZX.
For the differences between the IB and ZB variants for the 82378 see
the relevant section. Same for the EB ans SB variants of the 82375/4.
These chipsets are often paired with the SMC 665 for I/O support or
the NCR 810 for SCSI.
