Firstly sorry if I'm posting in the wrong place, there isn't a dedicated mac hardware section so I thought it more appropriate to post here. I have an iMac G3 98, and a wallstreet or pismo powerbook (can't remember) as well G3. It turns out that both machines have the same defect, the processor …

could it be that the ram size setting isn't just set by the bios, but also by some resistors on the board ? I've read once about configuring resistors to define the model, but I've never read anything about the vram. In the case of the model, I found that it is not defined by resistors, as I found …

1) Did you reference the part numbers on the actual memory chips (assuming they haven't been tampered with) and determine the real size and speed of the memory? 2) It sounds like you may have already tried flashing the BIOS from other GTS 450 cards, but did those detect the correct memory size or …

Why not flash the original gts450 bios? Quick answer: doesn't work. Long answer: These fake boards are OEM, which means it's as if you could choose a series of variables, directly from the manufacturer, such as: vram manufacturer, type (ddr3, gddr5), speed, thermal solution, pcb design, etc. Any of …

Well that sucks. Not sure why you're getting a max of DX2-66 on that though, machines I have that max out around there for emulation are an Atom N270 and a Celeron Mobile 1.6 (Dothan). My T7200 (C2D 2Ghz) manages up to about Pentium 200, maybe more, I haven't been emulating anything that needs more …

What speed of hardware do you need for PCEM to be fast enough for what you want to do? If I may interject, the OP's 13 year-old Intel Core2 Quad, while still perfectly adequate for many modern tasks, has single thread performance that is less than half of a current generation 100 US$ Core I3 CPU …

but virtualpc and vmware are not emulators, they are virtualizers, they are almost the same thing as i install win98 directly on my core2quad, they can emulate a sound, video and network card, but they don't emulate a processor. The first version of Connectix Virtual PC for x86 host computers was …

The kind of cards you think of for personal systems did exist for a few PowerMac in NuBus or PCI format, Sun workstations had PCI addons cards too with emulated storage iirc and in some measure for the Acorn RiscPC (only as a 486 or 5x86 CPU add-on card, audio and video were emulated). I have a …

Yes, but there are many implications, low security, difficulty maintaining a w98 and w10 network, low transfer speed, 2 machines taking up space (I use a desktop pc on my bed for lack of space, at night I have to disassemble everything to go to sleep)

I wanted something better than just emulation, I wanted something like there was on some macintosh 6100, a "slave" board, which contained a 486 processor. I've seen something like this on an industrial level, but they weren't made to work together with a motherboard traditional, they require their …

Exactly, I'm not sure what's bad for plastic, but some of my notebooks are over 25 years old and are in perfect condition, and others are breaking down. After 25 years, some displays have started to break down, the polarizing film seems to peel off the screen, creating bubbles. I don't know if this …

Don't worry about speed. The south bridge chipset is extremely old, the transfer speed is 33 or 66mbps, so a fast ssd would just be a waste. A CF Card or an SD would be great

I had a discussion like that with some devs on the msdn forum. The guys said it would be easier to rewrite windows 3.1 to be 32 bits, than to deploy direct x. I think the main advantage of 3.1 for me is because it is a simple interface on msdos, you can copy it to a floppy disk, and start it on …
