Since it was exposed to the rain, I took the plunge and disassembled it, washing it with clean Japanese water. After drying it thoroughly and powering it on, there’s no sign of it speeding up, and the memory seems to be 128k.

Does anyone know how to operate an old accelerator? I found one a few years ago when I took apart a mysterious Mac.

After all, this machine will go to the next owner. Perhaps I had a chance to replace the surface-mounted chips with Io shoes. I replaced the electrolytic capacitor. I decided that it would be better to buy another individual with the money I sold and try to repair it.

Let me tell you about my Mac screen. I think it will be cured if you replace the chip on the board. However, I have no idea which tip should be replaced. There is a floppy mark on the screen, so it seems to be cured. Do you have any opinions?

I wrote that it worked normally when I inserted the examined SIMM into the SIMM3 slot. However, the truth is that the total memory display recognized by the main unit was 4Mb. In other words, SIMM3 did not recognize the inserted memory SIMM. Should I replace UI4 and UJ4 in UJ4 from UI2 for chips...

OH! I examined the memory according to the advice. She worked fine. I examined the manufacturer of RAMSIMM. Recognized 6 out of 8 slots. Fill the remaining 2 slots to create an arpeggio. I plugged in two 256kb SIMMs at hand. I'm going to work now. This continuation will be challenged after...

Thank you for the information. Use this weekend to get the same brand with your RAM SIMM I would like to choose and fill the memory bank. Currently, I am ordering an IC near the memory bank and would like to try replacing the IC. My soldering technique is inexperienced, so I hesitate. I use...

If you replace the tip around here There is a possibility of improvement \(^_^)/ www

Thanks for the response. Memory bank A is filled with 1Mb SIMM. (It recognizes 4Mb capacity.) In that state, the machine normally displays a normal screen. However, if you point 1MbSIMM or 256kbSIMM to memory bank B, you will get an arpeggio. The logic board capacitors were recapped long before...

My name is nekogahora280. My SE / 30 has a machine when SIMM is inserted in addition to A bank I'm going to jail, but I can't identify the location of the failure. There are 4 (1Mb)SIMMs in A bank.
