1920x1080 on PM8500 built-in, Twin Turbo 128 — #6
This program and driver allow custom resolutions using built-in video on a PowerMac 7300, 7500, 7600, 8500, and 8600. I have used it to get perfect 1920x1080 on an LCD for over a m…

somebody already laid claim to it, but I do have another B&W G3 with similiar specs and I wasn't 100% on if he wants the monitor or not. So depending on that you could take…

What could I do to diagnose the problem?

get a volt meter and start tracing voltages until it stops
Mac Classic corpse — #3
When I switch on absolutely nothing happens, no sign of anything working. That's why I checked that the mains voltage could be seen on the inside of the switch. Hence the word 'co…
cube hard drive issues — #10
Take the VRM (DC-DC board) out and clean the contacts. While it's out, look for evidence of overheating. If anything looks scorched, you probably should replace it. Check the rest …

The spin up/spin down issues you are experiencing suggest a flaky DC board; check the CubeOwner forums for more information on this. While you're at it, check the PRAM battery and…

In 1985 Steve Beck wanted to be able to project a Mac's video with a standard TV projector. I built up a bunch of dual ported VRAM (parallel I/O and built-in shift register) with a…
cube hard drive issues — #8
Some newer hard drives are low power 5900 RPM drives. I've started buying only LP because the power consumption is about 1/3 of a typical 7200 RPM drive they're replacing. For inst…

Hello. I will leap in and express an interest in the B&W G3 also. I currently only have a G3 iMac to run OSX on and would like to get a 'regular desktop' machine. I love…

well I have checked the voltages and no issues the cube ran fine last nite. The day before the drive just stoped and then the machine did not boot ie no hard drive. May be the dc…

Propeller God? :lol: No. I've done one project with the Prop, a temperature controller for a reptile enclosure. It used a 4x20 character LCD and I had to write the driver for tha…

Just again out of curiosity, what other projects have you done with a propeller? It doesn't look like it's actually *that* trivial to add high-speed external RAM to one. (Unless I'…
startup chime twice on cold boot — #16
If you have a Fry's Electronics, grab the battery there. They have them for round $5 or $6. Otherwise places like Radioshack charge an unbelievable $21 for a battery.
eMac HD replacement - yikes! — #10
They're good machines the eMacs but they are very loud and huge. The main part is that retarded cable that goes to the power button.

I'm probably going to have to grab the whole frame. The scan doubling sounds interesting, but it will be displayed on an LCD monitor. What I think I'm going to do is make the bitma…

I'm using Mac OS 9.2.2, but I imagine it'll work even with System 7 (I could try tomorrow, as I still have an easily-bootable version of it... I didn't stop using System 7 until ab…

Excellent work, Noidentity. I suspect that you are repeating some of the investigations performed by the authors of the various shareware "set res" utilities, but it is much better…

Heh. While doing a quick Google I happened to run into your thread on the Parallax.com forum, and it looks the last answer in that forum is basically what I was suggesting, other t…

This is marvellous stuff. Under what System/s will it work?
eMac HD replacement - yikes! — #9
Geez... eMacs. The kind of machine that you have to stop every 15 minutes, get up and shout as loud as possible into a paper bag to restrain yourself from kicking the neck off the …
CC? Si, si! — #4
I did have my eye on that at first, having wanted a Colour Classic for some time (and for some reason, technically I don't need one but oh well). The lack of logic board is what pu…

Sorry, I was writing my post while you made your post. Taking the signal off the board is an option, but then the two boards are physically locked together. I really don't want to …

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
