Why the unusual frequency? — #12

As noted, why not just tap the frequency straight off the motherboard? It's right there. But whatever works for you. (And also, just have to ask... the specs for the propeller say…

I think the "16MHz" quoted for the Plus is probably nominal (ie near enough) and is actually 15.6672MHz Click to expand... Oscillators with a 7.8336 frequency and its multiples…

Although I thought it did have a bit too many screws I didn't find it difficult to open up and get in.

Interesting project MarkS. By coincidence, I've been reading the following similar projects in the last 24hrs: Prop-6502 laptop pPropQL020 and pPropQL I think the "16MHz" quote…

pcmcia ixmicro road rocket — #4

Zoomed Video is for video *in*put - it's a direct pipe into the GPU, bypassing the rest of the computer, and allowing video to be displayed on the LCD. The Road Rocket is a second…

Site works poorly with Classilla — #3

Excellent. For some reason I didn't think to change the style, even though I've done it on other boards for this very reason. Argh

The G3s have "Zoomed Video" connections on one PCMCIA slot, whatever that is. Normally it's for a DVD decoder card. :scrambled:

Beige G3 Conquest — #14

Back in 2006 when the 128MB DIMM I had in my iMac died, I booted it once or twice with the original factory 32MB of RAM. It took somewhere around 15 minutes for Jaguar to boot, and…

The Apple II uses a 14.31818MHz crystal (4x color burst) which gives it the ability to generate pseudo-color video on a TV. Click to expand... And so did the original IBM PC, i…

Why the unusual frequency? — #7

Everything in a Plus runs off a single crystal which was chosen for compatibility with the SCC chip and standard baud rates. If you change the crystal, the Mac may beep and start, …

Why the unusual frequency? — #6

15.6+- khz is the time it takes to produce a single line on a NTSC tv, so the apple screen is probably really running at or near ntsc tv specs Also it was very common in the 80's t…

Beige G3 Conquest — #13

Haven't played with it yet. No space on the bench to set it up. Leopard. Now there's a thought. I have a pre-loved 10.5 DVD, but I don't think the machine has the RAM. It'd be …

BatteryReset on a Lombard — #2

I can tell you that it very seldom works on a Wallstreet.... Resetting the battery can be done in Open Firmware, I gather, on a Pismo. Mind you, it hasn't worked for my Pismo's de…

What was the reason behind the odd clock speed? Click to expand... It divides evenly (ie by integer) to generate baud rates. But I imagine the pixel clock was an important reas…

Everything derives from the same clock. The frequency from the oscillator is divided in half for the processor and further for other IC's. The full clock speed is fed to the video …

If I were to swap out the oscillator, would it potentially damage the Mac? I doubt the .1664 MHz jump would hurt anything, but I want to make sure first. Click to expand... Ser…
