Errata to 25MGUPGD.DOC of 28 December 1988

     1- Background- On 256K chip diagram pin 8 is labeled VDD. This should
     be changed to VCC for comparison with the 1 meg chip and to be
     consistent with the truth table.

     2- Major Tools - Paragraph 1 should read: "heat source" not "head
     source".

     3- Procedure - Paragraph 3a. The 32 ohm resistor referred to should be
     a "33 ohm".
     
     4- Shareware Policy - Added further information of the Utility Disk
     including a file listing and description of each file included.
