The extraction tool fits into opposite corners of the 68HC11 socket; the bent ends will lift the chip
from beneath. Touch a ground point to avoid static discharge damage, and remove the case top.
Insert the tool and pull gently and evenly on both sides to extract the chip. Press the upgrade chip
into the socket, observing the small diagonal corner key. Replace the case top; your upgraded RT-
11 is ready to use.
You will return the old processor chip to LDG; the upgrade is sold by exchange only. The
processor chips are recycled and reprogrammed to minimize future upgrade costs. Upgrades will
cost about $10-20 with chip exchange, and will be announced on our web site when available.
Feedback
: If you have an idea to improve our software or hardware, please send us a description.
If we incorporate your idea in the RT-11, we'll send you a free upgrade as a “thank you”.
We encourage everyone who uses the RT-11 to contact us (card, letter or e-mail preferred) telling
us how well it works for you. We are also always looking for photographs of the RT-11 in use; we
frequently place such pictures on our Web site (www.ldgelectronics.com).
