These seem to be like memoryless ISD chips. I'm looking at an
app right now that could use ISDs or the CML parts. Plus for the
CML parts is that memory size is infinite whereas AFAIK you can't
hook up external memory to ISDs. Minor glitch might be the memory
chip availability situation but wouldn't pooh-pooh the CML altogether
for future consideration, I'll get a price on them at least. Big downer
is the bandwidth, only 4kHz, despite CML sampling at up to 128kbs.
The one I use now has a bandwidth of 18kHz, around about cassette
tape quality, which I need for good music sampling
