PC Board Revision
PC Board Revision Notes
The revision of the PC board is noted in copper on the bottom of the
board.
It only changes when the board is redesigned.
The "as built" revision is noted in the white "rev" block on the top of
the board.
PC Board Revision A
October 2018.
Original board design.
Released for production as no changes were required.
PC Board Revision B1
19 July 2019
Added PSI5 transceiver device and related circuitry.
Removed the MOSFET switch for the VDSI bus supply to the DSI3 Bus Master
device.
PC
Board Revision B2
~ 1 August 2019
A hand modification to the original rev. "B" board.
Remove pin # 21 from J1. This disconnects CPU signal PCS1 from the
PSI5 transceiver TRIG input.
Install a small wire from J1 pin # 25 (signal PFECI2C0) to the hole on
the PC board for J1 pin # 21. This connects CPU signal PFECI2C0 to
PSI5 transceiver TRIG input.
PC Board Revision C1
31 August 2019
Correct the signal change described above.
This results in the removal of wire via 8 (WV8).
No modifications to the board.
PC Board Revision C2
10 November 2019
Hand modified the board to work with the external AVT-441 "DSI3 Boost"
board.
Refer to the modification document for details. (Request a copy
from the factory.)
PC Board Revision D
~5 December 2021.
Changed the 4 MHz clock device. I need to build a batch of boards.
At present there are terrible shortages of electronic components.
I could not procure the original clock device, so I changed the
board layout. The new clock device is slightly smaller and uses
(what I hope) is a more standard footprint.
Also included in this revision are changes to the board to incorporate
the hand modification changes to "C2" needed for the AVT-441 "Boost Device".
