Haven't seen that card before but going by the chips I think it was meant to interface with lab equipment. Reminds me of the ada-lab cards which also used two of the r65c22p1 chips.

Picture 1: Its a Super Serial Board II, for connecting to modems and printers.

Should be relatively inexpensive. I have seen them brand new in the box, still sealed for anywhere between $9.99 to $24.99. Although some sellers up on eBay have lately lost thier minds and are charging up to $50.00 for one. Smile

The one that has the 44 Pin IDE interface block is one that I have never seen before. It looks to be some sort of IDE controller card that can be used in an Apple II, but if it's for a hard drive interface, I would believe that there would be a bit more circuitry onboard. Is there any writing on the back?

Hmmm?! Smile

thanks Wayne, gsmcten

I'll ask the guy to photo the backside of the board and will report back. Thanks again for the clues!

PS yes it is the unknown /maybe HD interface card I'm interested in Wink

Hi all,

I think the card isn't a IDE controler. It's just an I/O card. The two 65c22 are VIA (take a look at http://pdf1.alldatasheet.com/datasheet-pdf/view/129884/ETC1/R65C22C1.html). In addition, all the IDE controlers for Apple II lines need an EPROM with firmware. This card has no EPROM. So be careful...

Amauget,

I looked at the Spec Sheet and I see what you mean, but what I do not understand is what the 44 Pin Header could be for. It has to be for some kind of IDE I/O?

It's just a serial controller interface that uses flat cable. Nothing too special.

Hello,

This chip is multi-purpose oriented : the specs are two 8 bit bi-directional I/O ports and one serial bi-directional I/O.

The header is just for connecting user stuff to the multiple I/O of the chips.

So..conceivably, what could you connect to with this card?

You will have to excuse me for asking, but I am not that familiar with this type of I/O card. I am used to the APPLE card with the 25 Pin connector (at least I believe its 25, it could be 19 Pin?). Smile

gsmcten,

You can connect whatever you want : relays to command some stuff in the house, switches to detect changing states (you can do an alarm system for example) and so on...
The only limit is your imagination !
This type of cards can also be use in laboratories for probing measure instruments.

Re: Identifying an unknown card for apple ii

thanks for your help. since you posted the seller has noted that some boards are missing IC's so I've withdrawn interest and he's cut the price to clear the remaining 3. Same link as before.

thanks again, really appreciated
