Vectrex32s are back in stock. I have 19 available (I had 20 made, but one was DOA). You can order one here.

Thank you for the patience in answering these questions (and so many more to come I'm sure).  I had the same ones.  I'm looking forward to jumping in!

News and Updates / More Vectrex32s available, now with "no-buzz" support!

I have ten Vectrex32s available for purchase. If you'd like one, you can buy it here.

The is a new revision of the hardware that supports all Vectrexes, both the original and the late model "no-buzz" Vectrexes! BASIC programs written on the older Vectrex32s will run on this new hardware and vice-versa (assuming the old Vectrex32s have been upgraded to firmware version 1.15).

News and Updates / Version 1.15 Released
« Last post by Vectrex32 on May 12, 2017, 01:22:31 PM »
Version 1.15 has been released. It consists of bug fixes and a very minor new feature. If you already own Vectrex 1.10 or newer, you can download the firmware here. If you still have version 1.00, please read this.

Many thanks to "Astrosynthesist" who found and reported many of the bugs.
No, controller 2 doesn't exhibit the same behavior.

Now that you've fixed reading controller 2 Y axis, does it exhibit the same behaviour?
If not, could it be some kind of memory conflict?
Any luck with the weird Controller 1 Y axis behaviour?

You mean where the terrain shrinks? The short answer is "beats me".

I played with it a little.  If I draw the same LEM regardless of the joystick (i.e. the same amount of thrust coming out the rocket bell), the problem still occurs, so it's not that the LEM drawing is affecting the terrain drawing. If I read the joystick as digital instead of analog, the terrain problem doesn't happen.

There's only one digital-to-analog converter in the Vectrex and it's shared between the joystick and the vector drawing. So my hypothesis is that reading an analog joystick affects the D/A converter which affects the screen. I asked Malban about it and he didn't have any experience with it. He said he'd look into it, but he might not be able to get to it immediately.

I have found these bugs and fixed them for version 1.15.

General Discussion / Re: Adjusting the Frame Rate on Lunar Lander

There are other people who know more about this stuff than I do. But I think you want a fixed frame rate throughout the game. Otherwise, the brightness of the lines on the screen will vary and, in the case of the Vectrex, the rhythm and the volume of the buzzing would change!
