The TI blobbed cartridge boards

Recommended Posts

The cool thing about blobs is that they still had those via's all around... so for hard to dump carts, you simply have to attach jumpers to the via's and to a socket (put into an eprom programmer to read). Easy to figure out which wires are which data/address line by which pin they go to on the expansion bus or bank switch chip.

The blobbed versions of The Attack use a similar board--and those have only been found as loose boards as well. It looks like these boards were being designed as a cost-cutting measure, as that would seriously reduce the required size of each board. The question there is: does the move to blob cost more or less than the standard IC chip? If more, it would negate the savings introduced by the smaller board, if the same, it would reduce costs, and if less, it would reduce costs even more.

 

I find this topic very enlighening, as there hasn't been much said about these boards in the past.

 

Oh, so the blobbed carts are officially COB carts? You know, I have a The Attack proto in a case marked COB. The casing is slightly different from the standard case. I believe it has 4 slits in the bottom and no screw/middle clip. When I got it, the guy (Bill Barneia?) said it was a new cost cutting technology TI was experimenting with. Not sure if I ever took pics of the case.

Please do take a picture of the case, Toucan. I don't think those cases are documented anywhere else. . .
