Hi,
I am building a TF536 that I got as a gift.
The PCB silscreen font size is tiny and of a really low quality on the board. In the BOM I see that there are supposed to be three resistors mounted on the bottom of the PCB, R1, R2 and R3, however I can not find them :ugeek: . I can make out one that looks like "R4" though. Could anyone help me find a photo of the underside of the TF536 in a high resolution so that I can see where the resistors are supposed to go?
Thank you!

Re: Help with finding component locations on the TF536
There are two 1K resistors next to the IDE connector.
If you don't use buffers, you can also populate the resistor networks with 0 ohm RNs.

Re: Help with finding component locations on the TF536
May I ask another question, do I need to mount IC9 and IC10 if I do not intend to use buffers. I see images of unbuffered cards with IC9 and IC10 populated so I am confused. Also in the BOM I found there is a resistor at R3 (CRCW120647K0FKEA), I am not able to find R3 on my card. The font is so tiny but perhaps it is for an older revision?
Thanks!
Thanks!

Re: Help with finding component locations on the TF536
IC10 and IC9 are the buffers between the 030 and 68K bus. You need those. there is no R3 on the board that i can see when i loaded up eagle and searched.erkorh wrote: 08 May 2023 22:25 May I ask another question, do I need to mount IC9 and IC10 if I do not intend to use buffers.

Thank you for the clarification and reply! Getting close to finish the card now! :D

No problem, removed. I followed the BOM that was linked from the thread with the name "NEW BOM" in this are of the forums :)exxos wrote: 13 May 2023 17:32 Can you please upload files and not hotlink to external sites as we don't allow it thanks :)
