This will begin to make things right...
I pray to the yard sale gods every Saturday, and last week they answered my prayers and smiled upon me: I found the geek holy grail of a working Amiga 1200 with monitor, external floppy, power supply, mouse, and a %&$#?@!%&$#?@!%&$#?@!%&$#?@! ton of (mostly pirated) programs, games, magazines, and documentation for $100. The hardware was all stock original with no HDD or accelerator so I did some research about possible upgrades. So far I have ordered from Amigakit a kickstart 3.1 chipset (i had 3.0) and 4GB formatted / bootable Compact Flash Hard drive with IDE adapter that has workbench 3.1 already installed. It will mostly be a games machine at first but if it appeals to me down the road I may want to do more. That being said, I was hoping to get some advice here about a few things. My budget is a few hundred dollars. I could afford more but don't want to spend it until I know I am going to get a lot of enjoyment out of the Amiga. Gotta test drive before I buy.
1) After I have the Amiga HD installed and the machine buttoned up, what would be the best way to copy files between my PC and the Amiga? I've heard a CF card with a PCMCIA adapter for the Amiga is a good way to go, but how do I format the CF to Amiga format and then write files from my pc to the Amiga formatted CF card? My understanding is that PC and Amiga formats are not compatible.
2) Since it is mainly a game machine at first, would there be a benefit to adding an accelerator? Amigakit is selling an ACA 1221 Accelerator that is in my price range, but would it worth getting for me? It would be fine with me if only 90% of the games run well on my Amiga - I happen to have a gaming PC that is very good at emulation and Far Cry 4.
3) Is there a USB floppy emulator that would work without needed any mods? I have zero interest in soldering or rewiring.
4) Can anyone recommend a basic but serviceable graphics card so I can use the Amiga with a modern LCD?
5) Is the PCMCIA the slot used for networking? Any suggestions for a basic network adapter.
6) Do all memory upgrades only use the trap door accelerator port? (meaning that I could not install an both an accelerator and a separate ram card at the same time?) I do understand that Amiga accelerators also come with extra ram installed.
7) If I totally pimp out my Amiga with upgrades, would I need to get a better power supply? I've heard the original power supplies aren't very good.

Does anyone have any other upgrade advice or Amiga advice in general? I may not realize that I'm missing something obvious.
9) Last but not least, any game recommendations?
Damn this post is long - sorry. I'm extremely curious :-)
