A couple of things that might or might not be correct:
- Doesn't RISC generally require larger executables? So the switch from 68k to PPC would have automatically increased code size.
- Certain modern processor features require a lot of overhead. Multithreading comes to mind.
- To allow true...
The "processing horsepower" was definitely lacking in earlier Macs. Incomplete Quicktime Musical Instruments (essentially a preset sample player) were introduced with Quicktime 2 which in turn required System 7. I don't completely remember if the instruments also required an 68030 or higher or...
Check the completed listings on ebay for SE/30s that were actually sold. 300 € might be reasonable for a unit in good condition. Computers that boot but show problems seem to sell for under 200 € in general. But admittedly the prices can also be on the high side.
To give you an idea: During the...
I was able to make the IIsi talk to a NEC Multisync EA190M and a Panasonic Panaflat LC50s but not to a DGM 19" display. The latter works with nearly all my classic Macs though - but it also refused to cooperate with a NeXTstation so maybe it's the display itself. I think NEC MultiSync monitors...
A couple of interesting things in this circuit:
AGND and CMMGND pins are both connected to digital ground. Usually AGND signifies analog ground.
For some reason both sides also have different capacitor values for identical circuit positions: C6 is 1uF while C24 is only 0.1uF. Also, the...
As I said I will be able to make detailed tests only after I got it recapped. It might well be that you are correct about this.
My experiences come mostly from a (recapped) IIsi (same timeframe albeit different video subsystem) which is behaving somewhat strange in the video department.
I'm...
LC arrived. Dead power supply, logic board probably needs a recap too. But it boots in general. Tests will have to wait after I got everything in order.
I'm not sure about this. My experiences with a IIsi are similar: adapter and monitor work with a different computer, adapter works also with the IIsi and a different monitor. Perhaps there is a sync signal that somehow differs.
Anyway, I'll be getting an LC soon (condition unknown) and will run...
Not sure if it is "working" in the complete sense.
(Please correct me if I'm wrong.)
That the floppy gets ejected immediately seems to indicate that the LC is not booting from the hard drive. Hence it's waiting for a bootable floppy - which the floppy in the movie obviously isn't. If it were...
Yes, the "Pomeranian" part gave this away somewhat.
Anyway, I've recapped a IIsi, a Performa 475 and an SE/30 so far; so if everything else fails it would at least not mean shipping the machine around the globe...
Another thing: I think without the VRAM upgrade the LC supports only 512 x 384...
