There are disk images for all of the original Mac disks available on the
web. You have several options on making the disks. Go here:
http://www.mac512.com/ssdl.htm
First of all, the 128K and 512K Macs were single-sided, double-density
(SSDD) ,400K, 3.5" disks. You can use Double-Sided, Double-density disks
(DSDD). You cannot reliably use the common Double Sided, High Density
(DSHD) disks that are used on modern (?) PC and modern Macs. At first I
tried and they fail miserably. The DSDD disks can be found on the web if
you search for them (I got some at
http://www.provantage.com 10-pack for
$3.96)
Once you have the proper disks, you need to have a disk drive capable of
formatting and writing to them. The 400K drives were replaced with 800K
drives in later 512K models and their successors, the Mac Plus and SE.
Later on, "Superdrives", capable of handling both the 800K and 1.4 MB "PC"
format were put into Macs.
You have to place a [blank] DSDD disk into one of your Macs and "erase"
[initialize / format] it for 400K (a.k.a single sided). If you are able to
format it for 400K, you are in business! I know that support for 400K/800K
disks is included in System 7 and earlier.
Here are the steps:
Download the files off the web to you PC.
Make DSHD floppy with the files on them on your PC, and transfer them with a
"superdrive" to your Mac's Hard drive.
Format a 400K DSDD disk and copy the files to the 400K disk.
You can then boot your 128K/512K Mac from that disk.
----------
An alternative is to get a startup disk for the Mac with a terminal emulator
program that you can use to download files to via a serial connection
between the PC and the Mac. MacTerminal 1.1 or later and Zterm are two
programs that work. They can accept .bin and .hqx format files and build
clickable applications on you floppy disk.
Using your SE/30 or LC to make the bootable disk is a lot easier.
