A few newbie questions

[frax]

Just got my first PCjr, 128k, upgraded with Pico ATX, Flash Floppy and a parallel port sidecar.
No modem, original floppy removed.

1: Surely I can run this without the original floppy fan right? It's a bit noisy.

2: I copied PakuPaku to to a floppy image and ran it, hangs on startup sometimes but once it starts it's all monochrome.
It it just me? Not enough memory?
I'm using a normal tv connected via composite. IBM startup screen is in color so it shouldn't be a PAL/NTSC problem.

3: FlashFloppy = floppy images, is there any place I can download a few nice game images? All I can find is Total Mega Huge DOS collection 42, 17GB full of Zips,
which unzips to a gazillion more zips wich each contains .EXE/.COM, .Dat etc which I have to copy fo floppy images for each game.
Not really what i'm looking for. Found a few nive images on http://retrograde.inf.ua, but I want some more

I think the technical reference says that the fan is to keep the media (diskettes) at a reasonable temperature when in use. If your machine is completely solid state and the larger heat generators are gone (the floppy drive and the power card) then you can probably run fanless, or substitute in a more quiet fan.

I can't remember the details on the screen mode, but it might be your monitor having trouble picking up the colorburst signal. I've seen this on other systems and newer monitors; as things warm up the monitor fails to detect the colorbust signal and reverts to B&W. We had a devil of a time at VCF West in 2019 with this as we were trying to run an Apple 1 through a series of composite to VGA converters, all of which worked for short while and then spazzed out. The PCjr is a bit more compliant with respect to generating the composite signal correctly, but newer equipment is just not tolerant enough to make it reliable.

To your software question. Try searching for Abandonware in your searchbar. (Sorry but I won't directly link you to it, you have to do some of the work on your own )
