About me edit
I am a long-time, off-and-on contributor to Wikipedia. I'm new to Wikibooks with the intention of writing a book about programming the 1292 APVS family of video game consoles. These include Radofin's 1292 Advanced Programmable Video Sytem, the Acetronic MPU 1000, Interton VC4000 and the Waddington's Videomaster / Voltmace Database. In 1982 I started working for Voltmace and programmed a couple of cartridges for them.
This book is part of a larger project of mine. That is to create more interest in these neglected consoles and investigate just how capable they really are. Back in the day memory was expensive. Many cartridges were limited to 2k ROM. Some were 4k, and a few were 6k ROM with 1k RAM. In my experience development times were short and I think done by lone programmers or very small teams. SO I wouCd like to see what might happen if I can use the full 6k+1k format, and exchange ideas with others.
To this end I have started a blog, sig2650.wordpress.com, and built myself a development system. Although I started writing tutorials on the blog, I think that maybe wikibooks would be a better medium for such an endeavour.
I am very much in favour of making this all a community effort, so feel free to contribute.

| eorz r0 | |
|---|---|
| Exclusive-OR r0 with itself is an efficient way to set it to zero |
 | When using indexed addressing, the register operated on must be r0 You cannot do something like loda,r1 foo,r2+ |
 | The PVI is accessed at addresses starting at $1F00 |
