So I read that taking a sawtooth/DA 533 mhz board is a cheap and pretty good upgrade for the cube. I did do this, it did say 533 on the chip, however the computer boots and reads it as 400 mhz. I did do a few PRAM resets and upgraded the cube to the latest firmware. Is there anything I'm...
I've tried original Mac upgrade cards (IE Radeon 8500, Radeon 9000, Radeon 7500) and flashed ones and they all do the same thing. The only one that works right off is this rage card that came with it. I boot it up and there's some sort of rainbow color screen happening and I'm really not quite...
So I purchased a boxed IIFX from Japan. Looks to be in good condition. Came with foam, boxed KanjiTalk 7, boxed Hypercard, boxed keyboard, mouse...all hooks. But the most surprising was this:
Apparently they sold the IIFX with stands in Japan...which would make sense since they were limited...
Was a rather fun project. I bought a 2 Spicy O clock, new back panel, made 60 ns video ram, overclocked the 040 to 45 mhz and added a RGB amp connected to a vga socket. So it's RGBS out. Works great and I like how It turned out. Since it's 45 mhz, 60ns video ram, and a video out, I decided to...
So I'm trying to trace the RGB/S connections on this motherboard. I found the RGB signals going into the 343S1091 Antelope ramdac, but the composite sync is going into the 343s0164-a MemCjr memory controller. So I'm guessing the H/V comes from the Antelope ram dac, but I'm not able to trace is...
Got a Color Classic II main board that was turning on, but the screen wouldn't go on and there was no sound (and this is on a known good analog board). The CC2 board was also completely recapped
Looked around, making sure I didn't make any errors, I looked around online and noticed the 341s0788...
So I was looking at the L2 cache card and noticed that it had 32 pads for each chip, but was using only 28 of them for 32x8 (256k).
The original chip on there is: https://www.datasheetarchive.com/pdf/download.php?id=4d1abe23f2f7d82516765643adf153033d176e&type=O&term=KM68257BJ x8
Looking at the...
So I installed a 575 in my color classic and installed a PPC accelerator. I also put 128MB of ram which is seen correctly in 040 mode, but then when I turn on the PPC accelerator, it goes down to 32MB. Is there a reason for this?
So I watched Techknight's video on youtube for troubleshooting the board...I got to the part where he was checking the main cap which turned out to be shorted on mine. I took it out and found the two areas to be shorted still. I'm wondering where I would move from here? (Mines been completely...
So I purchased one of these from Japan for around $150. There were no pics of the insides, so I was kind of on edge since it could have had an exploded battery.
Well, I got the machine and not only was there no exploded battery, there was a Mystic upgrade already in it (575 board) with a...
Since the other thread/PMs went caput due to the server loss, I'll make a new one. If you are interested in new sets of 64MB (16MB x4) for $95 + shipping Lmk here or give me a PM. They will be arriving in a few days. I think the original price was $90, but unfortunately a little hiccup in...
So I asked Doug if I could use his design to make some modules and sell the rest to people to which he was fine with. I wanted to see if there was any interest in these. Obviously each FX would need a minimum of 4 modules, IE 64MB of ram. These boards are 4 layer, so it's not the cheapest to...
