Does anyone have the datasheets for the Intel 420TX and 420ZX? All I can around is the first few pages from each, which is of not much use. So if anyone has the full datasheets of these, it would be greatly appreciated.

Same here, the Intel Peripheral Components 1994 pdf had the most but still very limited info.

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....

Let me know if you find one.

In the meanwhile, the datasheet for 420EX can be found and it has similar feature set as the 420TX.

Yes did find that 420EX one. The 420TX/ZX used 3 chips, not 2 chips like 420EX. Odd that the docs to the
82423 DATA PATH UNIT (DPU) and 82424TX CACHE/DRAM/CONTROLLER (CDC) are so hard to find.....
Will dig around some more later, found the Intel Classic/PCI i486 Baby-AT models BP4S33AT, BP4D33AT, BP4D266AT
used the 82424TX/82423TX chips so maybe some digging that direction will be helpful...
