Logic Module ID? CS-1139-1

[Steve in VA]

I'm trying to figure this logic module out. Can you help?

and informed me """87 CSX LM is CS1079 or 4467415 (which would put a "415" on the connector and chip)"""

Anyway, mine is CS-1139-1 Supplier 7902 01/05/90. On the blue connector outside is 640, also the second to last chip inside is 640.

The very last chip is either 016 or depending on how you look at it 910.
It does have a map on the outside, but I was told its a differnt case possibly. I'm hoping its a 87 CSX computer.Thanks for any help.

Yeah no "640" LM on our list :( Anyone got any more numbers?

[sdac guy]

The CS1139 number means it was a Shelby Automobiles box, but I don't have a reference for that number. I do have a reference for a "640" cal. It is the 86 GLHS stage 2 which was originally sold by Shelby in the performance catalog.

Another thing that would point to it being an 86 box is the fact it has two chips in the lower left corner of the board. 87 LM's only have one.

Good info Barry :clap: Can we add this to the computer P/N list?

[ShelGame]

I show that as the 'StageII' GLHS cal. Both the 016 and 640 binaries are posted in the repository...

[86Shelby]

Any idea what the difference is between the two cal numbers?

[ShelGame]

One chip is cal data only, the other is mostly code with some cal data on it. They go together and I don't think you can mix/match chips...

[86Shelby]

Ok, that makes sense. I was thinking there may have been 2 different MP GLHS cals.

Thank you all for I.D' en the logic module. Now I'm on the hunt for a 87 CSX LM since I dont have one. It doesnt have to be the Stage II for now. I may start off with my 3 spare 86 TII modules for the Rampage I'm building. Its due back from total paint in about a month.
