Re: Update 1541-IDE

Hi Antitrack!,

(Just my 2 cents)

I guess, most people on this list are creative "enough" to have plenty
of ideas themself, with more or less time, faith and determination to
realize those ideas in a physical form... usually this latter ability
being the bottleneck. So.. why don't just "you" go on producing the
thingy you're describing?...

(Truly, no offense meant).

Best regards,
