    RT809H - Old Philips IC S87C751 (80C51)

    Hello everyone,

    I got an very old Philips IC S87C751 that I would like to dump; unfortunately due to its old age this IC is of course not in the list for the RT809H.

    Is there anyway to add this IC manually? My experienced with the RT809H programmer is still quiet limited.
    I do see there is an CFG directory in the application folder but so far I haven't been able to find any generic instructions for setting it up.

    Hope someone can help!

    Thanks!

    does your programmer support any other 87c51 versions?

      RT809H Programmer Firmware Corrupted
      by Teeheeze
      This is a shot in the dark, but I was just using my RT809H programmer and it got stuck in a certain state so I power cycled it. Now, the device LED just flashes quickly and does not connect to the software. I've tried to update the BIOS of it and it fails. I went so far as to remove the ROM from the programmer itself but it's some weird chip (I believe ATMEL, but I can't find any datasheet on it) so I've been unable to read the BIN from it w/ my other programmer. Chip has ATMLHC4C56BM CN written on it (I think). I'll upload an image. I have the programmer's BIN ready to program it manually. Anyone...

      The new xgecu T76 vs rt809h programmer
      by sassan
      hello,

      i want to buy a new programmer mainly for use for laptops bios chips and i'm between the Xgecu T76 and the famous RT809H.
      i think that T76 is faster wich makes it the best choice for using Pogo pins,i asked the support if it supports Mec ships found on some Lenovo laptops i didn't get an answer yet.

      i would like some ideas and which one do you recommend?...

      The right BIOS Programmer - The right software (HP Elitebook 820 G1, 840 G2) no soldering, EC, DMI, ME
      by STKR123
      Greetings badcaps community,

      I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
      So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

      Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

      I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

      These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

      I learned that desoldering...
