Thanks, will make the checks again within the week. Will also get a normal battery for replacement. Will also try to zoom in on Y5 while the computer is off, but running off battery to see if the frequency is still in spec, as well as see if the 2.9v battery even runs the crystal in the first...

Removed both D7-8 and measured. Both are good, reinstalled, and working. Measured Y5 and it is spot on per the picture. Measured UK14 pin 2 and 1Hz is present (think my crappy scope is loading the circuit and distorting. MacBatt/CR2032 was at 2.9V, which is where the previous one was before...

Thanks, I had assumed I could not measure the crystal directly since I lack high impedance probes, but will try tomorrow anyway. It booted and is working properly (less the clock running), without the battery installed. Can also remove D7 tomorrow and measure out of circuit. Thanks for the...

I ran it previously without regard for if the clock was working or not. Ran it again this morning since adding an Asante, and it locked up (any other work does not lock it up, and only one attempt was made before rebooting and running benchmarks with Snooper and MacBench, which completed...

Oscillator Y5 - C131 & C129 good ground (16MOhm on other side) Clock Path (as far as I can trace without understanding how the 1Hz comes out of the UE9 RBV) UK14 p2 -> UD11 p43 good UD11 p23 -> UE9 p103 good R40 = 1kOhm R40 -> +5v good (measured UD11 p23 -> F1) +V to RTC UK14 p20 -> D7 p3 good...

No it does not flicker or do anything unexpected. Have the logic board on the bench now and will start tracing things out.

IIci had very little corrosion and it was isolated to pin 7 of UE13. Cleaned the board and recapped with tantalums from DigiKey. Seller shipped with PRAM battery removed and there is no damage or evidence of the battery having exploded. The clock was originally working, but now it just stays on...

This is resolved. It was indeed a sync-on-green issue that was resolved by changing out the monitor. Still using the DIP setting 1478 without issue now. Original LCD (washed out image): HP ProDisplay P201 PN: C9F26A Mfg: 2014 Working LCD: Acer X223W PN: ET.EX3WP.003 Mfg: 2009 Guess it's a...

IIci with a BMOW Sync-inator on a early 2010's LCD monitor gives a washed out image. The graphics are clear and crisp, just the gamma is wrong. Any greyed-out text is invisible unless I select uncorrected gamma in the monitors menu. It has been recapped a few days ago, and the only corrosion...

Installed the print and only had to modify the VGA shroud by removing some plastic material and make space for the BlueSCSI. Good clearance from the PDS cards, and also doesn't obstruct the HDD/LED header. Overall a good design and was exactly what I needed.

That's perfect, sending off to print now. It eliminates the potential I/O errors of SD card extension as well!! Thank you!

Does anyone know of a .stl or pre-made expansion panel that has slots for both VGA and SD card? I have one for my bluescsi v2 to mount it to the bay, but it does not fit with both of the PDS cards mounted. The bracket cannot be modified since the physical bluescsi would also be in the way. I...

Yes, thanks for the support. It works great.

My apologies. I responded with the requested images last week, and again yesterday once I received and tested with the molex->berg cable. Will try tomorrow to see if it boots properly without the RM2 fitted.
