[Coco] Help with Drivewire

I found this EPROM from eBay EPROM, 27C64A-15F, 64K (8K x 8) 150ns, 5 Volt, 28-pin Dip 5 Volt 27C64 | eBay will it work or not? I still need to find away to program it.

I can't emphasize enough that this is a better way. The signal to noise 
and distortion of the cassette recorder is 30 to 40 db worse than the 
signal to noise and distortion of the pc's audio channel. Whereas the 
cassette load is often done poorly and the volume setting on the 
cassette is very critical, the pc's lack of the cassettes dc bias noise 
makes a perfect load 99.9% of the time.

The presence of an ac bias circuit in a cassette recorder was a huge 
advertising advantage, and raised the price of a cassette recorder out 
of the means of most who did not grok that the difference in price was 
worth every cent of the increased cost. I had one once, paid nearly $150 
in 1985 dollars for it, but my kids found out it just worked and wrecked 
it in a week. I never bought them anything better than a $20 mayfair 
from then on.

Use the pc's audio, it Just Works(TM). Leave the cassette recorder in the 
rusty mists of time where it has belonged since the 1970's.
