Title: EII error on memory option board Post by: n.flanders on October 16, 2011, 06:44:53 AM Hello all together,
when running the memory test, i get Err BnkA 60010 Data: 09 S/B: 01 which leads to IC 26 on the memory option board. swapping rams (even the complete segment) did not hav any effect - afterwards i got the same error code. So i resoldered the IC sockets of the whole segment and the capacitors. But unfotunately still the same error code. >:( Does anyone of you have an idea waht else might cause this malfunction?

Do you have a problem in reality also, I mean, do you hear glitches in the sound ? (I assume you have a basic 512K EII, right ? Should be... because you have a memory option board... but I'm asking anyway) Title: Re: EII error on memory option board Post by: n.flanders on October 16, 2011, 01:27:39 PM yes, it had bad effects of the sound.
Now i´ve exchanged the ics of the whole two last segments with new ones and... finally it works!!! ;D ;D Thank you for your help anyway :) But please tell me: how do you get to ic 24 interpreting the error code?

I think it was IC24 because the error message from the Memory Test says: - Address = 60010 - Wrong bit = bit 3 (09 should be 01, so 00001001 should be 00000001, which means bit 3 is different, taking into account that counting starts with 0 at right side of bit representation) The memory segment table says that address 60010 is located in the IC range Memory Board IC20-27. The schemas show that the third bit data line is at IC24 (the one with the MD0B3.D signal) |
