I have recently bought a external floppy drive for my new mac. How could i put a game from the internet on a floppy and have it work with my 1984 macintosh
Hmm. My goto vintage Mac would be a Macintosh IIci because you could really utilize both of those machines. The Mac 128k could run original Macintosh software that only works on the original machine, and the IIci could pretty much run everything else.
However, if you want to simply download software and just make floppies for your original Macintosh, then perhaps a nice PowerMac G3 or G4. While the PowerMac may be too fast or incompatible with quite a few older bits of software and games (but not too many), it will certainly make creating floppies a breeze. It'll have an ethernet card built in, it'll be able to run Classilla which will get you onto Macintosh Garden to download the software, and it can run Disk Copy which will let you make the floppies.
Unfortunately, it looks like eBay has gone insane with prices. And I mean more than normal. I would recommend checking out your local Craigslist. Do a search for Macintosh or PowerMac, hopefully you can find something for under $50.
So if i get a g3 it should be able to read/write files that are able to be used with the macintosh 512kCan the G3 write 400K floppies? My G4 can't even mount them.
A G3 is certainly useful in many other respects. I have my G4 MDD sitting next to my IIsi, and they trade off many bridge-type tasks.
An SE might be another decent option - they seem to be the most plentiful and cheap machines on ebay. Definitely check craigslist, local machines are almost always cheapest and easiest if you can find them. Alas, I don't get many in my area, though I have picked up a few nice finds.
is there any other cheaper alteritivesThe beige Power Mac G3 is the latest machine that can read and write 400k and 800k floppies. The blue and white G3 and all G4s lack a built in floppy drive. Add-on drives don't support the requisite variable spindle speed for these disk formats. Software-wise, Mac OS 9.X or earlier must be used as Mac OS X cannot access the built in floppy drive in any Mac. I've found this a helpful guide for making 400k and 800k floppies: http://siber-sonic.com/mac/newmillfloppy.html
Edit: Do note that Mac OS 8 and later cannot write data to or read data from 400k disks in the Finder. You can't simply drag and drop individual programs or files on or off the disks. You can write disk image files to floppy from Disk Copy though. If you want full read and write support, you'll want a Mac that supports Mac OS 7.6.1 or earlier. I use my Performa 6360 as a go-between.
So as long as it has a built in floppy drive it should work, so whould A G3 with built in floppy workFloppyEmu, while ridiculously cool and useful, would most certainly be more expensive than a used Mac.
Macintoshguy1984, seriously, look on Craigslist. Do a search for Macintosh or PowerMac in the computer section. Find the cheapest, working Mac, and you should be all set.
