I have a reloaded board in a Simasimac status. Current clock signals are:
Y1 = 32Mhz in spec
Y2 = 32Mhz in spec
GLUE PIN 17 = 32Mhz in spec
GLUE PIN 18 = 16Mhz in spec
Y3 = Erratic, Intermittent supposed to be 16Mhz? Sometimes around 10, sometimes no reading.
Anyone have any idea what might be...
absolutely not sure but it's my best theory at the moment because it had a good deal of corrosion when it came off the bombed board. Pins were OK and it cleaned up ok. Wouldn't hurt to have another if I can pick up a iici or whatever relatively cheap.
(for idiots perhaps...). I've got a Simasimac reloaded SE/30 board and I suspect the GLU chip is at fault. It cleaned up well but was kinda rough when I got it off the bombed board.
I have checked all pin continuity several times and everything checks out to destinations. No bridges also...
I did try but nobody ever responded to my request. I might pop in every once in awhile. I just noticed this was the exact issue I'm currently having with my reloaded board.
Hi, did Will explain the root cause of the slow death chime and horizontal lines? Sorry if I missed that in the thread. I'm in the exact same situation with my reloaded board. Thanks for any info.
sorry I see the explanation now. Disregard.
It's true. Apologies for asking again but I figured I'd get all my questions in one post and was still hoping there would be some way to test it with an oscilloscope, multimeter and the datasheet if it exists. I will accept defeat lol.
As I’m working on an SE/30 reloaded board, a few questions have arisen, If anyone would like to offer any knowledge or advice, I’d appreciate it.
1] U32 Crystal Oscillator (see pic) appears to be polarized based on the silkscreen on the board? As I was cleaning the parts, the writing on the top...
