Identifying DRAM
I accidentally posted this in the wrong forum but I couldn't figure out how to delete it there. Sorry!
Does anyone know if you're supposed to connect passive or amplified speakers to a Performa 6400? I heard that the built in subwoofer acts as a regular speaker but switches to a dedicated sub after you connect speakers to the system. Just want to make sure I connect the intended type of speakers (passive or amplified). Thanks in advance for your help!

It is pretty common that people run accross a DRAM DIMM or SIMM that isn't labeled with an obvious capacity. In that case, to properly identify the size of the module, one must either install it in a compatible Mac or use magic to decode the numbers on the chips to figure out the overall capacity of the card.
Well, someone has figured out all the magic for you.

I have yet to find a DRAM IC that I cannot identify this way...
Peace,

I've linked to this thread from the other one.
On the 6400, my understanding is that the sub becomes "active" (maybe "more active" is the best way to put it) if you connect external speakers to the speaker jack on the rear of the system. They should be powered speakers, because the 6400 doesn't do any special powering of its speaker port. Many of them were used with Apple's monitors that had speakers built in, but it should work just as well with whatever powered computer speakers you have on hand. I happen to have used mine with the side-firing speakers on a Multiple Scan 15 (non-AV model, though it did still have speakers) and with the glorious audio system of an AudioVision 14-inch display.
Fun sidenote! With BeOS R5, you can manually control what audio outputs on the system are used, including enabling the subwoofer with no external speakers attached, and enabling the internal speaker when there's a headphone or speaker device attached to the system.

Happy though I am that the site exists, because it has many times been of great use to me, it has also been often a source of frustration, too. It seems not to have been updated in recent years, and there are many holes in its listings, especially of SIMMs.
