Never heard of it ;-) From the description, however, I'd guess that it
dates from 1990 or so ...

Unless the device can do EPP, it's a losing proposition.

There were a few devices like this from manufacturers like NEC, HP and Iomega.
The original PPA (for Bernoulli drives) looked like that.

Many of these things were, in fact, based on the 5380.

The rest of the adapter seems to have been built from standard off-the-shelf
components.
If the device is as old as it seems (most of these things have been based
on single ASICs for at least 4 or 5 years now) it almost certainly cannot
do EPP. In that case, you would not be able to burn CDs on your CDD-2000.
If you still have the DOS drivers for it, and are interested in doing
some experimentation, it may be possible to get it working in SPP and PS/2
mode. If you don't have the DOS drivers, your only hope is that somebody
else here might recognise it as something else relabelled.
