Hi guys, I'm sorry but due to the extreme personal problems I've had this year I just don't have *any* time to spend on Vectrex related matters or this mailing...
Just a quick note to let everyone know that I'm closing down this mailing list now. It's been fun, if a little quiet for the last few months. I'm sure I'll see...
My condolences Pete. Take your time, as always family is more important than anything else. We will see you when you return. Again I'm sure I speak for the...
I'm going to be disappearing from here and RGV for a time. Unfortunately my mother passed away a few hours ago after a long illness, so I'm not really in the...
Re: Joystick port question ... finalised, has anyone made any? << I have an LRTF controller that I made ... just 4 buttons side by side ... Plus it has 9 pin...
... Looking at the schematic, it would seem that the 6522 (pin 21) is connected to 6809 (pin 3)...even though it is not carried through like A2 and A3. ...
I am so not a hardware guy, but if anybody's gonna do this, it's probably someone on this list... (My appologies to everyone who's heard this a hundred times...
I'm not sure it's such a good idea... My feeling is it's trying to turn a vector system into a raster system and I'm not sure it's really worth the hoops you...
Hi, ... Good point, I'd missed that. In fact the Vectrex joystick port pinout is very similar indeed to Atari's standard pinout (for the 8-bit computers at...
... Huh, interesting...I've seen that so many times...but I never made the connection... they must have know about LRTF controllers and at least used them...
Brett, DON'T use an EPROM eraser the UV is MUCH too strong, it'll burn the coating off. Using the sun is good (we don't have any in UK !!), but if you don't...
... It doesn't really matter what software you use, as long as you can get the B&W images to print onto acetate, if that's the route we are going. I have to...
... That's good advice! What exactly is a PCB guillotine? (XY table?, scoring machine?) Sincerely, Brett Walach /*******************************\ ... ...
... So that custom single chip wasn't you? I thought it was for some reason...hmm, who was that guy? ... I agree. ... Wow, that's good advice. I've done the...
OeK I have finished describing all the connections within the 3 IC circuit of the Animaction cart ... So what are the merits of attempting to replicate this ...
Animaction Described! ... OK ... ... EPROM pinout. ... << I'll compare the EPROM setup to the 6116 RAM memory chip ... Did you see the note on RGV from the...
Hi, me again with another tip :- If you're going to make a lot of boards - join multiple designs together (in your PCB CAD package) and buy the biggest piece...
Hi Brett+Rob, sounds interesting !!. There's seems to be 3 versions of the cart. The single 'custom' chip version I saw a while back, a 2 chip version (a guy...

... this ... I'd definitely like to see it...does it have 2 IC's (ROM & RAM), or is it integrated like the one Richard H. already cracked open? It would...
Re: Vectrex Animaction PCB Design ... Hi! I just opened a loaner Animaction cart ... I will take photos and photocopy both sides of the PCB and work out the...
Re: Joystick port question ... "down", "left" and "right" on the circuit diagram. Anyone know why?<< Who knows ... but UDLR (1234) is standard Atari 2600...
Just noticed on the Vectrex circuit diagram that the joystick buttons 1 - 4 are marked "up", "down", "left" and "right" on the circuit diagram. Anyone know...
Can anyone clarify something for me? Is the IRQ\ line of the 6809 connected to the interrupt line of the 6522 VIA, or is it simply tied high via a resistor? ...
Been a bit quiet in here lately....so a question.... Is there anyone on the list who makes his own PCBs, say Veccy cartridge boards? ;-) If so, what schematic...
Hi, I've been experimenting with the "print" routines in the EXEC ROM - specifically "Print_Str" and "Print_Str_d". What I can't figure out is the relationship...
