If the info for the Checksum modification is not up on http://www.spies.com in the game archive, test equipment section, then I will forward it to Al and he can add it to the info there...it is an easy mod, you just need to add a toggle switch and connect it somewheres on the board, grounding a resistor if I recall. I have made a few other mods to the Cat Box, including beefing up the power supply so the Cat Box can actually power up smaller logic boards (I use that for Gottlieb System 80 MPU testing, and added an indicator LED that blinks when the UUT (Unit Under Test) has RESET stuck low or is pulsing...

Hi to all TTL'ers!

I have just acquired another CAT box but this time I got 3 pods with
it.(6809,Z8002,Z80)
I haven't quite got to grips with it as yet but have a few questions if
anyone can help

Which Atari games use the Z8002 & Z80?
The Z80 pod I got was uncased..... did it come this way and why 4
connectors?
Did Atari ever have a manual which accompanied these pods?
What other Atari pods were produced?
Anyone have the Atari info for the mod required to do ROM checksums with
the CAT?
How good a job does the CAT box do? (Are all my troubles over?)
Anyone got a flyer for the CAT box?

Thanks in advance
