I just saw your youtube video ... awesom work!!! Thank you for invitation, but I would like to stick with recreating custom ICs.

I am always interested in that kind of development. I will take a look how you are proceeding with the development ... maybe I can help with something. The only problem is the time ... work/family/hobby balance and other retro equipment I managed to pile up in last two years, which needs to be...

Seems like I was lucky today. After tracing signals with the scope and inspecting everything with magnifying glass for several hours I was lucky to notice that VGC IC pins and it's socket had micro gaps between. So I took it out and i cleanned IC pins/legs and pushed them towards outside of the...

I was just reading your thread "SE FDHD Restoration" you posted above. Is looks much, much, worse on the area around the battery then my case. But this is very useful, thanks! When I bought it, a guy who sold it to me said that Mac was working after he stuffed it somewhere in the attic. I can...

Just for the sake of sharing experience I will post more images here than needs to be post. When I opened the Mac I found battery on the opposite side of the board sicked to the front plastics near the speaker as on the image below (this one is taken from the video I was preparing): It seems...

Hi, I'm back with the immage of the IC. Or, even better, maybe you could sell me the whole board? Because the battery damage is substantial (had to put new RAM sticks, the old ones were unusable) and I don't know if some other part is potentially damaged. I did try to wash the board twice and...

Thank you cheesestraws, I will take a look at it. I need to check if it is worth time and money. Also, I would like to build it by myself if I can do it im my workshop. Hi LaPorta, I will send you photo of the IC, maybe you have it. Althou, I have Eurpean version of the Mac SE FDHD, and I do...

Finally I managed to do some probing with the scope. Unfortunately the "Gate array" IC is dead, it does not provide a clock signal to the CPU and it is not showing any signs of life. But luckilly I just installed IDE2SD to the Macintosh Classic and it works great. Thank you guys for trying to...

Hi, yes, ignatio sent the same. Thank you both. I do already have these schematics. I was just hoping that someone has a complete one. I will try to use this one and check some routes on PCB, hopefully it will be the right one. Seems to me that P4 connector is missing ("hard to read image")...

Hi ignatio, Thank you for the tip about the battery. I thought that this is the case, because that is the only logical thing. I was just wandering if it might not be the case because I found somewhere in the swamp of manuals I managed to download that the battery "should" be inserted on the...

Hi to everyone! I am new to the forum, and need some help with my Macintosh SE FDHD. I just refurbished and fixed one Macintosh Classic and it works perfectly except SCSI HDD (which sometimes requires side kick to start spinning), for which I already purchased SCSI2SD on eBay and can't wait...
