I'm new to the Apple modding community, but having looked through these pages, I have to say I admire your work. And having a personal screwdriver set and a spare Mac, I couldn't resist for long.
First, some background on my systems. Besides my Pentium 4 Windows machine, I have two Pismo PowerBooks - one with a 400MHz G3 and my main computer with a 500MHz (very difficult to find). I bought the 400 back in May last year, and was so impressed that I hunted down one with a 500MHz processor to use as a donor to upgrade mine. I found one in November - it had the chip, 512MB RAM, a 20GB hard drive and an extra power lead. I got it cheap as the screen had met its maker - a long crack from corner to corner. The screen is pretty much dead, so I've decided to mod it.
What I want to create is essentially an iMac G3 TFT. In a nutshell, attaching the working logic board assembley, with hard drive, optical drive and processor, onto the back of a 15" LCD monitor. I've found a suitable candidate for a screen - it's a BenQ with a normal D-Sub 15-pin VGA lead.
The machine has survived being dismantled, and boots nicely. I can use the computer with an external monitor in Mirroring mode, but I would like to somehow attach the screen as the Primary display. Could I hack the Pismo's internal display connector to adapt it to a normal VGA port? I have the display ribbon from the original screen, and am confident with a soldering iron. If this is complicated to do, does anyone have a wiring diagram for the Pismo's display header that I could work from?
Failing this, could I disable the internal port and use the external VGA connector as the primary monitor? The screen has the same specs as the Pismo's internal screen.
Secondly, can I disable the battery system in the laptop? It seems trivial, but I'd like to eliminate the charger card from the machine as it's heavy and quite large. Also, this computer will be exclusively mains-operated. I'll hang the logic board assembly off the back of the screen and stick a custom enclosure over it, with the power supply integrated, thus a battery will be unnecessary.
Thirdly, I removed the screen inverter only to discover the sleep light is built onto the inverter card. Would it do any harm to reinstall the inverter exclusively for the sleep indicator? Or should I modify it so the inverter is disabled and if so, how?
Lastly, does anyone know of a wireless card I could install in the Airport card slot besides the original (they're damned hard to get a hold of)? I'd like this machine to be wireless-enabled, and am not fussed about speed (as long as the crad is not 802.11a-only).
Currently, the machine stands at this:
- Logic board assembly
- 400MHz G3 processor
- 128MB RAM
- 6GB Hard Drive with OS X 10.4.8 installed
- Modem card
- Charger card
- Airport card slot
- PRAM Battery
- Power switch
I also have the speakers, with the intention of mounting them inside the monitor if the integrated ones aren't up to spec. Everything listed above is still mounted in the lower case; I've removed the upper case and keyboard along with the screen, and it still boots. It will not boot if I take out the charger card.
Sorry for all the questions, but this is a project that I feel could have great potential - it'll be unique, and I'll have a desktop Mac to use.
Thanks in advance to everyone who posts,
