Project Resources
Project resources are allocated on a per student basis. This means that a two-person
project has twice the resources that an individual project has, etc. You have already been
issued a kit and a quantity of ICs. The following items are available on an individual
sign-out basis. Note that the quantities listed must suffice for the entire class.
Quantity Item
200
Proto-boards which do not have switches, lights, or
power supplies. Suitable 5 volt power supplies are
mounted on the lab benches. Each proto-board will
hold about one-half the number of ICs that can be
mounted on your kit.
100 50 pin 3M ribbon cables for kit to kit connections
The following items may have to be shared. Cables for the TVs, and VT100s must be
signed out and returned daily.
Several VT100 Video Display Terminals with RS 232 cable
15 Monochrome TV Monitors with BNC cable
15 Color TV Monitors with cable
