NOTES & ERRATA Versatile Multiple Announcement Recorder (February 1995): The 47k x 8 `SIL' resistor packs for RP1-3 are available from Rockby Electronics in Melbourne, and also from Daktron Electronics (phone (02) 671 1333) as Allen-Bradley part number 709A473J. The parts list incorrectly shows R28 as 2.7k; it should be 2.7 ohms, as shown on the schematic and PCB overlay. The schematic shows C12 as 22nF, when it is actually 10nF, and also shows C19 as a disc ceramic when it is of course an electrolytic.
