Here is the revision information for those wanting to know what the
difference is between the versions.


Rev 5.0d4 21-Nov-93

1. Double oops! There was another mistake in the file
   "PAL-NTSC_SWITCHER.IFF".  The resistor and wire were shown to be
   connected to the wrong pin of the PLCC plug. The error in this
   diagram will cause no damage, but will simply cause the computer
   to think there was a memory error, and put up a red screen, when
   set for NTSC mode. Reconnecting the wire and resistor to the
   proper pin will fix the problem. The file "PAL-NTSC_SWITCHER.IFF"
   has ben updated to version 2.0 which shows the proper connection.


Rev 5.0d3 23-Sep-93

1. Initially we said that the 8375 Agnus would not work. This used to
   be correct. However, there is a new Agnus marked 8375B that has a
   part number of 318069-03. This is the only version of the 8375
   Agnus that will work. It must say part number 318069-03 or it will
   not work. The 8372B Agnus still works fine, and it also has a part
   number of 318069-03. The text file "TTMAP50D.DOC" and picture file
   "TTMAP50D_PARTS1.IFF" have been changed to reflect the new Agnus
   option.


Rev 5.0d2 8-Sep-93

1. Oops! This is what we get for working on a diagram late at night.
   In the picture file "PAL-NTSC_SWITCHER.IFF" one of the wires that
   connected the switch to the board was on the wrong side of the
   resistor. This has been fixed in the diagram.


Rev 5.0d1 7-Sep-93

1. We were able to buy most of the parts in bulk which decreased the
   cost. This is reflected on the order form price list.
2. We were able to get very good pricing on the 2 megabyte Agnus chip
   and include it as an option. This is shown on the order form.
3. We included an IFF diagram showing how to add a PAL/NTSC switcher.
   This diagram is the picture file "PAL-NTSC_SWITCHER.IFF"
4. The label on the 256x4 RAM chip in the picture file
   "TTMAP50D_PARTS1.IFF" incorrectly said "PAL". We changed it to
   corectly say "256x4".


Rev 5.0d 21-Aug-93 Initial release

1. No changes. This was the first release.
