lc ii Macintosh LC II Recapping and Dishwasher - please don't!
Alex posted a topic in 68k LC & Performa
So this is not about the retrobrite that the 8-bit guy completed, that turned out very nice. Instead it is about this really bad video he did, sorry I know some of you may like him but this video was wrong in so many ways that I had to warn potential viewers. I couldn't comment on youtube because they were not available for this video. Do not twist off caps from any logic board, it's not in the manual as it were for a reason … you run the risk of ripping of the pads that capacitors are soldered to. Once a pad is removed through the force of twisting off- 31 replies

I have a LC III and an LC II, and as you know, they have an empty FPU socket on them. It would be nice to put in an FPU in them, right? You know it. But I also have a couple of LC Ethernet Cards with an empty FPU Socket on them as well. Actually, of the 3 cards I got, 2 have a FPU in them (68882 @ 16MHz) and one has an empty socket. Its obvious that they were made for the LC. This got me thinking - the 68K can support multiple FPUs. So can I put in an FPU in the logic board and another FPU in the ethernet card? Though the CPU can support it, will the software support it? Will there be

I have just recapped the LC II. After a recap, it worked correctly -- it had a steady picture, it chimed and it booted off the SCSI CD-ROM into System 7.5. Then I installed the Asante network card, which was originally installed, and it stopped to chime, but it boots and works correctly. Removing the card did nothing. Also the board was throughly cleaned twice, so there is no cap leak residue. I discovered that it actually chimes, but extremely quietly, if I put the speaker next to my ear, I can hear a faint chime sound. I also triple checked all my recap work, and found no problems. Also

This has been on my mind for years, and have never acted on it. But where does it say that an LC or Classic is stuck at 10 Megs of RAM? Most II Series data bus is 32 bits, thus making a 4MB address into 16MB of RAM in 32 bit. But the LC and a couple of others are 16 bits, which would make a 4MB address into 8MB of RAM in 16 bit. Thus the 10MB RAM size in an LC is just in 16 bits. If the bus can be expanded to 32 bits, it increases the RAM size to double! Since finding the Classic II and comparing it to the SE/30, there is very little difference between 16 bit Classic II and the 32 bit

My LC II motherboard with what appears to be leaky capacitors; the board boots and works except the video output has some corruption (thin vertical lines that become closer together as you increase the bit depth/color count).-
