I saw that one too. I wanted to buy it but $40 postage to AUS stopped me!

The black slot cover makes me think it was intended for a Model A 5150.

I had also seen that out there before, but had not noticed the chip dates. Davong was an early third party manufacturer of IBM PC add-on parts. They also made a hard disk controller that ran under DOS 1.x.

It is - notice outside of the black color the wider bracket. The problem with these is the dip switch settings. W/o a manual it is a pain to get one going. I have two MS RAM Cards, one with original box packaging and driver disk but no manual for either one....

I know the feeling. I've got a 512k lavasoft card I can't get going :(
