I can use the 74LS74? If you change the VC need adjusting. Check the power supply but do not connect to the system. You can check Paula and Denis chip on A to see if they datashee properly.

Each component removed noted on the picture to take a history.

Here is what you need: Yes, my password is: Well, I’m not planning on desoldering the VCs from my motherboard to datashedt the current values but you can boot the computer regardless what values your VCs have.


Note that it must be the T version to have TTL-compatible input characteristics. Unfortunately I couldn’t find that IC within my area.

Use lemon juice to neutralize the acid from battery. I found the solution. Sorry for my English. If the chip as Paula and Denis, etc, have stained legs, leaving them in lemon. In the diagram there are different capacitors, my motherboard has more capacitors.

Clear the lemon juice with hot NOT boiling water and dry quickly. Remember, the A motherboard is multilayered. Who Really Owns Hardware? Like said in the upper posts they have different speed because: Not find differences in datasheet.

Nov 15, 5. Hello, Have a look at this table for 74XX74 speeds: DO NOT forget to connect something in the power supply to not work in a vacuum.

Remove the chip that are in sockets.
