A500/A2000 Technical Reference Manual revised version differences
 

I noticed my copy of the A500/A2000 Technical Reference manual has several pages which say REVISED in the top left corner, but the PDF version of the manual available online doesn't. So in case anyone is interested here are the differences between the online PDF and the later revised version.

Page 103
PDF version says:
Burst NTSC/PAL colorburst. Pin 18. To obtain the correct PAL colorburst
signal, the video plug-in card must multiply this signal by 1.25 (i.e.,
3.55*1.25 = 4.433 MHz).

Revised version says:
Burst Gate NTSC/PAL colorburst gate. Pin 18. Used to remove colorburst during
the vertical interval. Active low.

Page 106
The PDF version shows pin 36 of the video slot as "Reserved for Expansion".
The revised version has pin 36 "/PSTROBE (B2000 only)".

Pages A-5/A-6
This is the Amiga 2000 Form Factor diagram. [In the PDF version, A-5 is PDF page 241 and A-6 is PDF page 244. There are a couple of out-of-order pages between them in the PDF.]

If the PDF version the board diagram on page A-5 has a different numbering for the PC/XT/AT pins on the connector. The pins marked are A18, A1, A39, A1.
In the revised version the corresponding pins are marked 36, 2, 62, 2.

Similarly on page A-6 of the PDF version, pins on the the video slot diagram are marked (from left to right) 18, 1, 18, 1.
In the revised version those pins are marked 36, 2, 36, 2.
