Hi all,
Found a little something in a "lucky dip" so to speak with some other
boards I "needed" Any one have any idea what the hell it is?? Follow the link:

Any info would be apreciated.

Just airing a pet peeve here, but I won't traverse any link through
Geoshitties with all those gawd damn pop-ups of theirs unless I absolutely
have to :(

Sellam, I've d/l the jpeg already for closer analysis. Email me off-list
and I'll bop it to you, no ads guaranteed.
I hate Geocities too -- printed off a bunch of their pages and the
'commercials' that I thought weren't there printed out anyway.

I think it is a communication controller or an intelligent serial board :
the chip Zilog Z0853006 is a serial communication controller, the Nec D8237
is a DMA controller. IC52 and IC53 (near PL2 connector) are RS485 drivers
and in the same zone there are some RS232 drivers.
The first step is a dump of the ROM near the Intel 8254 : it can be supply
many information.

The ROMK is not in a socket unfuatunatly, So it's not going to be
convienient to read it. Though If I have to I supose I could desolder it and
plug it iinto the Eprom programmer and do a quick read if I really cant find
anything alse....

There is another solution : plug the board on an old ibm compatible computer
(the bus is AT bus) and try yo dump the ROM code with debug or other
programs : normally the rom fill the memory at address C800 or D000 or D800
and similar.

You can probably plug the card into a PC and use something like Checkit
to find the address and headers of the ROM (Checkit displays the first
70(?) bytes of each ROM). Then use Debug or another utility to dump it to
a file.

It's a very good idea ... I was not remembering Checkit :)
