Need help identifying hardware

Ibm / 300gl 6282-7
February 25, 2010 at 18:16:16
Specs: MS-DOS 6, 286
I have an IBM PC 300GL 6282-75U
The motherboard has two slots for ram, and there is an intel chip that reads SB82437VX and is dated '95

I need help with a few things for this PC.
It says on the case that it was "designed for Windows 95", however, there is not even enough memory to play Wolfenstein 3D on it..

There is only one stick of memory in it right now, I need help identifying what kind of memory is compatible with this motherboard, so I can buy more, preferably 64MB.

Also, this board has no built-in audio device. What soundcards would be compatible with this PC? Could I put a soundblaster 16 in there or something? I would like to have a soundcard that is compatible with my older DOS games.

It currently has an IBM 2559MB AT hard drive in it P/N 02K3493, (drive C:\) and has Windows 3.1 loaded on it.
Would I be able to add a second hard drive, a Caviar 21000 AT? That is compatible with this machine correct? I would like to put Windows 95B on it.

I have been doing as much research as possible on this computer to no avail. If you can help me know what I can do to make this computer efficient enough to run 95' and games like Red Alert, Duke 3D and whatnot, it would be much appreciated!

The IBM 300GL 6282 accepts a max of 128MB (2 x 64MB) of PC66 SDRAM. It has one PCI slot & one ISA slot but it appears that they're shared, which means you can use one or the other but not both at the same time. So you'll have to decide what you want or audio.

Thank you for the reply, it was helpful.

When I open the case, I see three ISA slots (titles isa slot 1, 2, 3), and 2 PCI slots. Perhaps it was a later upgrade?
One of the PCI slots was inhabited by an ethernet adapter which I removed, because I do not plan on using the internet with this computer.

Do you think a Soundblaster Pro 2 (8 bit) would be a good card to get?

Here's all the downloads available for your machine. Best to download everything now while it's still available and save it for later use.

More about shared slots. As jam said, these are shared slots and for each slot, you can either choose an ISA or a PCI card. The PCI connector is shared with the ISA slot just below it.

About any sound card will work long as it comes with drivers for Win95; I have a box full of 'em.

A nice PCI video card will probably be a little harder to find. The problem is chasing down an 8Mb or 16Mb card and gettin' it for nothing or next to nothing.

Does that thing still have the original 32Mb of memory in it? 1Mb or 2Mb of video memory? At the C:\DOS prompt, you can type MSD and hit the enter key to get an idea of what you have.

"there is an intel chip that reads SB82437VX and is dated '95"

That's the Triton II chipset. It will take 128MB of RAM, but it can only cache 64MB of it. This means that if IBM installed an L2 cache, any memory that you install above the first 64MB will not be cached, which can really hurt system throughput. So if you find cheap SDRAM on ebay, don't buy more than 64MB of it. Fortunately, it doesn't take much to satisfy Win95. '95 smokes on a DX2-66 with 32MB; it'll burn the house down on a Pentium with 64MB.

"Would I be able to add a second hard drive, a Caviar 21000 AT? That is compatible with this machine correct?"

Yes, that drive will work with your machine.

"Do you think a Soundblaster Pro 2 (8 bit) would be a good card to get?"

8-bits indicate a monaural card. Go for the stereo Sound Blaster 16.

An old ATI Rage PCI video card will run your DOS games quite well. The Rage also had great 2D acceleration, which will give Win95 a little more pep than the EDO-based onboard chip does.

Do you know of any small PC shops in your area? Many of these smaller guys hold a ton of old hardware that they sell for a couple of bucks each or even give away. That would be much easier and cheaper than eBay.
