A user recently contacted us about a RAM failure on their IIe motherboard, and inquired as to having it repaired. Of course we can help!
When running the IIe self test it would report "RAM 0 0 0 0 0 1 0 0". The number "1" in this case denotes a defective DRAM. On this particular board all the DRAMs were soldered and not user serviceable. With the right tools and experience however, this isn't an issue.
We desoldered all the old DRAMs, added new high quality Machine Pin Sockets, and replaced all the DRAMs. All new DRAMs isn't required since only one DRAM was defective, however the user requested we do so, and now will have spare parts to deal with any future issues as well.

sbtl "Apple //e Diagnostics"
ORG C3ORG+$300
* These routines test all 64K RAM, as well as the 64K on an Auxillary
* memory card (when present). With the exception of the INTCXROM switch
* of the IOU, all combinations of the IOU switches are tested and ver-
* ified. All configurations of the MMU switches are also tested.
*
* In the event of any failure, the diagnostic is halted. A message
* is written to screen memory indicating the source of the failure.
* When RAM fails the message is composed of "RAM ZP" (indicating failure
* detected in the first page of RAM) or "RAM" (meaning the other 63.75K),
* followed by a binary representation of the failing bits set to "1".
* For example, "RAM 0 1 1 0 0 0 0 0" indicates that bits 5 and 6 were
* detected as failing. To represent auxillary memory, a "*" symbol is
* printed preceeding the message.
*
* When the MMU or IOU fail, the message is simply "MMU" or "IOU".
