ahhhhr now its back again to the first issue. With the stuck bit2 at Right controller, and the issue descriped where the left controller affects the right one is none existing. So it have to be ay-3-8914 that is unstable in some way. I see from the schematics, then some 0.01uf capasistors are connected to some of the pins at the controller pins, maybe they are bad or shorted, would it be causing this issue ? c34,35,36,37,38,39.

ok seems like the stuck bit issue was solved after removing the ay-3-8914 and using some electronic cleaner at the socket and put back the ic again. Everything seems to work find for the Right Controller now. But i see another strange behaviour, when using the left countroller, pressing some buttons, actually will affect bit2 at the Right controller. Especially if i push the buttons hard. Also the pressing the disc, in some directions,at the Left controller will affect then right controller, but only bit2.

ohhh yes thats correct, also the fact for MSX computers. Hmmm could it be a bad ay chip. I might try to swap it out to check.

Hi. I was testing an Intellivision Model 5370 - PAL, mainboard is from 1981 There is a stuck bit at port 1FE, which is the Right Controller. No madder what this bit (2) is set to 0, if I press keys the other bits changes, but bit 2 remain 0, Also while the controller is not plugged in. Normally if nothing is pressed Port 1FE returns 255 (11111111 binary) But now it returns 251 (11111011 Binary). I assume its some logic IC that when bad or is it the CPU ? Thanks.

If anyone should be interested, here is the Memotech MTX charset for use in cvbasic. mtxchar1.bas

Some one told me some IN HOUSE diagnostics cartrigdes for the ADAM can test the KEYBOARD. But I think they did something to swap in and out the memory or something. I did not try to disassemble to see whats going on.

yes that was Andy Key, who made an PS2 expension card, even with loop, so you can use it together with e.g Super Game Module at the ColecoVision I dont know if its possible to make any more, maybe the components get hard to get. I have one myself by the way.

Hi. I want to use the Adam keyboard from a Colecovision cartrigde, it should be possible but not easy I guess, any one have some sample code ?

Hi. I want to develop something using CP/M at the ADAM. Do anyone have information where the VDP NMI address is ? the hook to jump to my NMI code?

Hi. Check this youtube video (Warning you will never get those 35seconds back, they are totally wasted!) Information for @Rev (no snow level for this one) @cmart604 I plan to release it on cartridge, in 20 different colors, so you can buy all of them xmasstar.rom

Hi there In some progamming groups at facebook, there was a challenge, how to write a program to display a xmas star. Mostly using text modes, but some people used graphics.

Have anyone tried to replace the Cartrigde connector, and if so, any good sources for quality parts ?

and also remember to (re)listen the "In Memoriam Keith Episode" of the Intellivisionaies podcast http://intellivisionaries.com/in-memoriam-keith-robinson/

Hi Working on my 13th game (ports) for the ColecoVision and since the game I am working on is very time sensitive, I search for a PAL Colecovision. I would also be interested its defective. Please send me a PM if you have anything you want to part with.
