Yes, I keep old E-mails to some extent and I found a report from
you specifying the following par_userint file:
vga mode [11]
font scale [1]
mouse speed [64]
input mode [0]
rx channels [1]
ad channels [1]
ad speed [6000]
ad device no [32]
ad device mode [0]
ad frag [8]
da device no [33]
min da speed [5000]
max da speed [44100]
max da channels [2]
max da bytes [2]
min da channels [1]
min da bytes [1]
check [2220024]



These were the par_wcw parameters:
First FFT bandwidth (Hz) [15]
First FFT window (power of sin) [1]
First forward FFT version [3]
First FFT storage time (s) [4]
First FFT amplitude [1000]
Enable second FFT [0]
First backward FFT version [0]
First backward FFT att. N [5]
Second FFT bandwidth factor in powers of 2 [2]
Second FFT window (power of sin) [0]
Second forward FFT version [0]
Second forward FFT att. N [7]
Second FFT storage time (s) [5]
Enable AFC [0]
AFC averaging time (s) [5]
AFC delay (%) [25]
AFC min S/N (dB) [6]
AFC lock range Hz [150]
AFC max drift Hz/minute [100]
First mixer bandwidth reduction in powers of 2 [4]
First mixer no of channels [1]
Baseband storage time (s) [200]
Output delay margin (0.1sek) [5]
Output sampling speed (Hz) [6000]
Default output mode [0]
A/D speed [6000]
Check [1110024]

The parameter file changes a little from version to version
but I think the above sholud make it easy to restore the
performance you had Sept 14 2001, at least with 00-35.
In case more recent versions run slower or behave incorrectly
on your 486 I would be very interested to know.
