Hi Guys/Gals...
The Atari AUX board/Maths Board, can use AM2901 bit-slice processors. Each
device can process 4 bits. There are four of these devices/chips on each
board. therefore, the board can process 16 bit numbers, which is what it
does.
Atari call these devices elusively "Transistor Arrays" - but they are
really these 4-bits per chip slice-processors. Each device is
interchangeable, you can swap any of them around on the board.
They are not 1 bit-slice processors, neither are the Atari chips
equivalent to to 4 x AM2901s. One 137004 is equivalent to one AM2901.
Hope this helps, there seems to be a lot of confusion over these
devices!!!
PS: These chips get hot, so faster 2901's the better and if you want to
protect your ageing game, suggest you consider heatsinking them.

I missed that KEY part of the original e-mail, aka I win the bonehead
award, with 4 gold stars for extra demerit.
The AM2901s from B&G are a replacement for a single 137004.
Sorry :-(
