- THE NAME OF THE MAIN TEXT FILE IS "ttmap50d.doc". READ THAT AFTER THIS.

- Changes and modifications to the project are shown below.
-
- Note that this file goes from latest release to oldest release.

-
- Rev 5.0d5 21-Oct-95
-
- 1. Since RAM prices have risen since we originally set our prices, we
- are forced to either stop selling the boards or follow the increase
- in RAM prices. Our markup on the boards is extremely small
- and we cannot afford to eat the difference in the price of RAM.
- If RAM prices rise more we will have to raise our price accordingly
- again, but at this time we don't anticipate it happening soon.

-
- 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.
