 TI99/4A here. Nice machine in some ways, but... quirky.

 Well, you wouldn't want to run Home Premium or anything like that. For
just "Vista Home Basic", it wants a "20GB hard drive with at least 15GB
of available space". Let's be generous and assume it only uses 15GB.

 Now, the most common C64 floppies could hold ~170KB of data per side.
So, let's see:

 15GB / 170KB = 92,521.4 floppy sides. So, round up and divide by two
for double-sided floppies, and you've got 46,261 floppies. Now, the data
rate for a 1541 floppy drive, with accelerator software and/or hardware,
could approach 4KB/sec. So, each floppy could be loaded in no less than
42.5 seconds. Assume some overhead, add 5 seconds to pop out the floppy
and either flip it over or exchange it, and you've got around a minute
per floppy. So, it could boot up in a mere 771 hours, or 32 days.

 But, of course, it doesn't *really* use all 15GB. Assuming you just
want it to boot, Vista Home Basic claims it'll run in 512MB of RAM.
Of course, my machine was swapping with a full 1GB, but let's assume
that's the minimum. 512MB/170KB results in a mere 1,543 floppies
(with one empty side), and it would load in just 25 hours.

 Now, making a C64 with that much RAM is left as an exercise for the
completely insane reader.

 Sincerely,
