The Roadrunner product kit included with this document is mechanically compatible with

both AM-167 based AM-1000 and AM-177 based AM-1200 computers. However, there

are some minimum revision requirements for both AM-167 and AM-177 boards that

must be met in order to be Roadrunner compatible. The minimum acceptable revision

levels for AM-167 and AM-177 boards (along with the minimum acceptable revision

levels for other AM-1000 and AM-1200 related hardware) are documented in the next

section.

Some AM-1000 and all AM-1200 computers contain a 68000 or 68010 CPU chip which

is soldered to the main electronics board. If this is the case with your computer, you

must make arrangements to have the CPU chip un-soldered from the board. Also, a

64-pin socket (included in the product installation kit), compatible with the AM-985

board, must be soldered in the location where the CPU chip was removed. The process

of removing the CPU chip and installing the 64-pin socket is a delicate procedure, which

if done incorrectly could result in a damaged AM-167 or AM-177 board. This procedure

should only be done by an authorized service technician.

Some AM-167 or AM-177 boards may have an old style side-contact 64-pin socket.

When installed in this type of socket, you will notice the AM-985 board will easily move

from side to side, even though it is seated into the socket. If you encounter this situation,

have your old 64-pin socket removed and install one of the full-contact 64-pin sockets

included with the Roadrunner hardware kit.
