What has changed in the primer since it was first published, newest first. If a section you followed last month reads differently today, this is where it says why.
| Date | Section | Change |
|---|---|---|
| 26 September 2026 | S3, S13, S15, Appendices III and IV | The keyboard, put right. The Einstein has two grey cursor keys, not four arrow keys: a horizontal one (right, or left with SHIFT) and a vertical one (down, or up with SHIFT). The three keys marked with a single arrow are the [, ] and ^ character keys. Earlier text said "the arrow keys type brackets and do not move the cursor", which describes MAME's mapping (its Left, Right and Up arrows press the three character keys; Tab and the Down arrow are the cursor keys), not the machine. In XBAS the two cursor keys move the cursor over a listed line, and ENTER stores it as it now reads. Appendix IV now has both keyboards side by side, and says what was checked in MAME rather than on a real Einstein. |
| 20 September 2026 | S17 | A new picture: three filled shapes - a square, a triangle and a circle - in place of the house in the sun. The three changes to try are new with it, and the section now says what the start angle does. PICTURE.ASC on the disc changed to match (disc version 1.1). |
