Is that you CPUWIZ?!?! I have my multicart!! I did not know that you made. I bought it from someone at ebay auction in...maybe 2004 or 2005. I don't remember what year I bought, name seller, and price either. I don't know how many you made. I'm glad. I found you this forum!! You made 5 of 5 correct? I just read the posts. Last night I was planning to sell it at ebay. I have not post yet but I will do soon. And I have not tested it. I don't have Arcadia 2001 system. I sold it. I did not sell this multicart yet because I lost it in the past. I was cleaning up in the closet. I found it in the box at the closet. I was surprised. I thought I lost it or my friend borrow it. I am glad. I found it. Whew! Here is picture. Serial #2 !! BTW, 5-11under, good luck that you make multicarts! Nice Cart ! Maybe let the community know , im sure one of us would love to buy . I know I would I only recently acquired my Arcadia but im amazed it slipped under the raider . I have heard of the sytem but never seen one in the wild . I was pretty lucky to pick my one up just the other day .

I have an AUstralian Arcadia 2001 , I would love one of these carts . Can you please put me down too . Cheers

I have done the same mod except I had to bump up the 22ohm resistor to 55ohm due to the top half of the screen tearing . I have a good stable picture the only thing is when the bright colourd graphics/sprites are against a black background the leave a dark band horizontally with the bright grahpic . This is a US version INTV and im using a step down converter because im in Australia . BTW I also had to leave the RF module connected due to no picture issue . Does anyone have any idea if this issue can be fixed ? Thanks for your help Karl

What noticeable differences are there with the RAM upgrade ? Sounds like your really into your Coleco

I wanted to add to the above post but site wouldnt let me edit ??? Just for some extra info to reverse engineer the SECAM adaptation back to the orignal PAL board I had to resolder some cut traces and remove wiring on the back of the board . The crystal was also removed due to the SECAM RF video . Strange thing is they were done post factory on PAL INTV's . There are resistors and caps that are clearly cut . I guess there wasnt enough demand for the Mattel factory to make SECAM INTV's .

Heh....dig the Atari XE game in yer avatar. I too was suckered by Atari one last time and bought onna those. What was I thinking.... Anyway....the video garbage was prolly not related to the input buffer(s) going south. I'd check the pwr switch first, then the output voltages of the pwr supply. I've seen several just over the last couple weeks that were putting out wrong voltages. One had a 5v output that was close to 9v. This is baaaad for your board.... Haha , Actually I think apart from its ugliness and brief history , IMO is the best Atari I have . It plays the old Atari 800 carts and all the games are better in every aspect compared to the 2600 . Its an 8 bit console and top of the range in Atari console in the 80's . Unfortunately it had an Identity crisis and was marketed bad and too late anyway as Nintendo started to dominated . The XE is very rare here in Australia and I think I bought the last 3 on ebay a year ago and havent seen any since lol . Thanks for the tip on power , I will check all the voltages and give the power button an overhaul . But last night it played beautifully and for some reason NO display issues

Ok just to update : I have found the right 8.86Mhz Crystal and it didnt work . So I put in a standard 4.43Mhz which is usually used here in AUSTRALIA for PAL . and it worked !! I wasnt too sure what size at first as the only SCematics I could find was for a US version .US INTV has a 7.15MHz Crystal which led me to believe the equivelant in PAL . These are the components I had missing : This is the SECAM board I removed which has the RF : This is the AV mod I used from GAMEX : This is the result : Thanks for replying BTW , appreciate your help .

Thanks 5-11 and Yurkie , I swapped the IC's out for a new pair and its working flawlessly now . Thanks again , really appreciate it

Yes, but very little in the way of sprite animation variation and size in comparison. Mario is like half the size of Popeye. And you're already using multicolors on the in motion Bluto, Oliver, and then the backgrounds as well. True , I think its Olive-oil thou Are they your own screen shots ?

What about Mario in DK , He has more than one colour ?

The white band seems a little strange, but the on/off switch is a good first option. Do you know how to de-solder? I have an SMD solder station with the heatgun . I usually give it a little heat before I bump it up to 320c and the chips comes of perfectly .

Thanks Guys , Was was wondering if it was a controller chip . Looking at your PDF now 5-11 EDIT: I like the sockets makes things easier for the future . I will get a couple of those chips and sockets on way home . What about the picture going strange on me all of a sudden , you think its related ? or maybe the ON/OFF switch is buggered from me switching so much trying to work out the controller problem ?
