DEC Rainbow repair thread

I do not know what this is. The writing on mine is:

16-18998-00 Rev B
ARTTED 10265 HIPOTTED
8310

I tried searching for these numbers or text. But did not find anything useful.
 
I have to order the parts for my power supply. But I'll have to pad the order to be worth paying shipping or get to the point of free shipping. As of now I just need that one cap.
 
Still waiting on a few caps for the mainboard. Once I have those in and swap them ill try them out with my known good psu and report back.
 
Got my parts so removed the one cap from the PSU. I can't tell if this orange is from the cap or something else. It doesn't appear to be glue. The cap charges properly to 9v with a 9v battery connected. I don't really have an ESR tester. Here is a picture of said cap. The rubber appears to be a bit buldged but not by much. It's not a great pic from my old phone. Now I am not sure if this is the problem with my PSU or not.

If it was glue I'd expect to see more attached to the board itself. I was hoping to see another part with glue, but don't see any. Why glue this particular cap?
 
Guess it's glue, as most came off with alcohol, but not all. Some stayed on the board too.
 
So I received the Capacitors I was looking for. Bit of a nightmare with two sellers online. One who shipped them and they were lost and another who shipped them only 2 days after I oped a claim for no product.

They were the same caps as on my working Dec rainbow.

I received the other parts as well that I needed to try and repair the board. I was going to use my good psu and see whats what.

Well I wont beat around the bush. The system is very much dead. All the main ICs that are socketed are completely fried. Even the rx50 floppy controller and the 8088 daughterboard (tried the 8088 cpu as well as the other main chips, controller, z80, FDC controller, etc in good system all ics dead)

This system saw water damage. Probably for a long while. I have to assume someone tried powering it on without looking inside. Shes toast. Short city. I will keep the cards and put it back together. IF I dont find a board in a years time its going to the dump. I dont like doing it but what can you do. Ill probably keep the boards though. I spent enough time and money on this already.. Maybe ill just toss it. I have enough other things to work on.

What a shame.
 
I have another axial ceramic capacitor I could use some help identifying. IT has both ASC 224 and M85 611 stenciled on it. Is it a type 224 0.22nf?
