Kai,
any plans to order more - I am in UK and now have 2 possible donor boards - just got a new one on the ‘finds’ thread. We could go 50:50 on something maybe?
Went to look at a promising SE/30 here in the UK. On closer inspection there is what I imagine to be typical battery Damage to the logic board and case.
It has got as far as the ROM socket:
There are a bunch of RAM chips - 4xOKI and 4xMotorola(??):
A quantum SCSI Drive:
A Sony Floppy that...
I am in the UK and am thinking about ordering some of these. Basic green boards with the bottom side populated from the BOM/Parts Placement. I have at least one donor board that is in pretty bad shape.
1. Is anyone else interested in one of these - looks like minimum order is 5?
2. Can anyone...
Pretty much what I was thinking. I have a mouser cart with the F258's, UA-G8 and some resistor nets, and a couple of Zilog branded SCSI chips that I am working on finalising.
I am having trouble tracking down something for RP9 - they seem to be out of stock with a MOQ of 2000!
At this point...
I picked up this SE/30 board on eBay and I think it’s going to be a challenge. There is quite a bit of visible green gunge to deal with. I have scrubbed down with vinegar, and IPA soak and some contact cleaner.
Caps are off and there is some pad damage to repair.
Folks in here have pointed...
I picked up a 'spares' SE/30 logic board from ebay - OK I didnt look closely enough at the pictures, live end learn, and discovered once I started working on it aht the SCSI controller chip is GONE!
Looking at another board I can see an NCR 53C80 p/n 609-3400257 a few google searches are not...
My first ever Mac was a G4 15", I think the USB 1.0 model. I gifted it to my Niece to take to University here in the UK.
I saw this as a £0.01 auction on eBay and ended up picking it up for the princely sum of £16.00. The seller contacted me to say the keyboard had gone missing so the...
Raster I have done all of that - see earlier in this thread, its definitely Logic Board. The problem moves with the board and the 'good' board works in the 'bad' boards chassis. Good board with boot either chassis hard disk. I have swapped ram and rom around the two boards and even used s 3rd...
I am being ultra careful with the clips, this board has an odd mix of plastic and metal clips on the sim slots.
I don't think its the Semisamac (??) problem here. I have tried all combinations of ram and rom I can thing of and always get the same issue. The interesting thing is as a final...
The diagonals are camera artefacts from my iPhone - the screen is just parallel lines in real life.
Board has been fully recapped and cleaned thoroughly in IPA and dried.
I have a Rominator that I can try and some new 16MB ram sticks.
I have another SE/30 that runs fine without battery - I am...
So I have some progress to report. I checked all the continuity between UF8 -> UGC -> HSYNC Pin on the main board (Pin 11) and there is continuity everywhere there should be.
So I went ahead and replaced UF8 and I now have VSYNC. The picture fills the screen but is garbage:
The...
Just fired up my recapped SE/30 and put the network card back in. I found some diagnostics on the HD and fired these up and am getting an address error from the Hardware diagnostics. Card is using the dynaport driver but its a Shiva Access-T
The drivers seem to load and the led flashes...
Is it normal to have a Mac SE/30 with an 800K drive. One of My SE/30s has a PC compatible FDD which has successfully formatted and written to a 1.44MB floppy. The other won't have anything to do with the 1.44 Floppy disks and just ejects them when I try to format them. I have some old Mac...
So the recap is complete. The board has had 3 days to dry out - no smell of IPA. I re-assembled everything this evening and powered on, everything seems to be working plus the sound is now working again. A complete success.
So I am looking at the schematics. UF8 looks like it feeds into UG6 pins 2-8 and the VSYNC comes out of UG6 pin 14 which then connects to the PIN 11 on the Logic Board socket:
So I can check continuity between the UF8 and UG6 connections and continuity between UG6 pin 14 and Pin 11 on the...
