THE NAME OF THE MAIN TEXT FILE IS "ttmap50d.doc". READ THAT AFTER THIS. Note that this file goes from latest release to oldest release. Rev 5.0d2 8-Sep-93 1. Oops! This is what we get for working on a diagram late at night. On the diagram "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 file "PAL-NTSC_SWITCHER.IFF" 4. The label on the 256x4 RAM chip in the picture "TTMAP50D_PARTS1.IFF" incorrectly said "PAL". We changed it to corectly say "256x4". Rev 5.0d 27-Aug-93 Initial release 1. No changes. This was the first release.
