Bill Loguidice Posted December 22, 2006 Share Posted December 22, 2006 Well, some good news on my 'ditch the monstrous power supply' quest. I finally got the time to refurb the standalone Adam here, and it seems to work quite well with my PC power supply. CV mode works fine, as does Adam mode along with AdamNet and the floppy drive, and even the DDP functions correctly. Woohoo! The composite video out from the monitor port seems a tad weaker than with the original CV PS, but I think I can easily live with that. It's interesting about the monitor out weakness. It would seem to me if it could power a DDP and an internal modem AND not have to worry about the printer, that the display would be unaffected. Of course, based on earlier comments in this thread, it seems like the video output is one of the items most commonly affected by a non-standard supply. Is there any way you can confirm that there is indeed a difference? Also, I wonder if an Adam configuration like mine, with internal memory expansion, two DDP's and a disk drive would be compatible with that hack? Obviously there's no modem in there, but I don't think you were actively powering that anyway, right? In any case, if you can ensure there are no "issues", I'd gladly pay you for a hacked PS.

GrizzLee Posted December 24, 2006 Share Posted December 24, 2006 I have an aftermarket ADAM PS. It looks a bit homemade... but it works. I've had it for years. If there is interest, I can take a better picture of it. Quite honestly, I use my modified Colecovision. It has Component video out. It is incredible.

Murph74 Posted January 3, 2007 Share Posted January 3, 2007 Lee-- I'd love to see what's inside the homebrew PS. Also, I just gutted a Time Pilot arcade game and pulled the switching power supply out of it-- oddly enough it has +5, -5 and +12. I'm wondering if this might be the useful here.

If I get a chance this weekend... and I remember to, I will post some fotos of the innards. I don't think it is a homebrew Power Supply as such. I think it was offered as a commercial product. I know of the existance of 2 more of these. -Lee Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted January 5, 2007 Author Share Posted January 5, 2007 Also, I just gutted a Time Pilot arcade game and pulled the switching power supply out of it-- oddly enough it has +5, -5 and +12. DOH! Why didn't I think of that. I've got a nice little Chou power supply I will try out. Sure thing. If I get a chance this weekend... and I remember to, I will post some fotos of the innards. I don't think it is a homebrew Power Supply as such. I think it was offered as a commercial product. I know of the existance of 2 more of these. Lee, cool that would be appreciated!

Murph74 Posted January 5, 2007 Share Posted January 5, 2007 Well, Remo-- if you get to try it out, let me know! I don't even have an Adam here to TRY and make it work with right now-- my stand alone is in the parents basement still. Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted January 6, 2007 Author Share Posted January 6, 2007 Well, Remo-- if you get to try it out, let me know! Well I tried it out, and it works like a damn charm! I think I've found the perfect answer to my Adam power supply question, Woohoo! So long scary old linear power monster! Video looks good (doesn't seem to suffer from that slight degradation I experienced with the PC PS), DDP drive/AdamNET, floppy, keyboard all work perfectly.

One of these? http://www.happcontrols.com/powersupplies/powsup_xref.htm Was it plug and play? Quote Link to comment Share on other sites More sharing options...

One of these? http://www.happcontrols.com/powersupplies/powsup_xref.htm Was it plug and play? It's one of the 'Peter Chou' switching arcade power supplies. This isn't the exact model number of mine, but it looks very similar. http://www.happcontrols.com/powersupplies/80021500.htm It's not quite 'plug and play' per se, you need to connect a 120V AC line cord (and you should fuse it externally as well), and connect the right pins of a joystick cable, or the original ADAM cord hacked off the old PS, to the correct voltage lines. Here's a pic of mine with the AC and joystick cord (the ADAM business end ) attached. It's a beautiful thing! Quote Link to comment Share on other sites More sharing options...
Murph74 Posted January 6, 2007 Share Posted January 6, 2007 (edited) Damn-- I'm a friggin genius. lol Just kidding-- but good work Remo on testing it out! at least now we appear to have a workable solution. Wondering how this will compare to the PS Lee has??? Hmmm... these power supplies aren't new... wonder if maybe this is what Lee has in a box?? And now I'm wondering if I can use an Adam printer to power my Mame cabinet? Ok, at the very least, an arcade cabinet. I'm also thinking with a little fiddilin and some hotglue, you just MIGHT be able to make this thing fit in a standalone Adam case. Maybe even add a small muffin fan to boot! The possibilities are now limitless. lol Wonder if I'm using too many smiles here. Murph Edited January 6, 2007 by Murph74 Quote Link to comment Share on other sites More sharing options...

For those of us technically uninclined at the moment, who would be willing to build and sell something like this? Quote Link to comment Share on other sites More sharing options...
Pixelboy Posted January 7, 2007 Share Posted January 7, 2007 OK, next question. For those of us technically uninclined at the moment, who would be willing to build and sell something like this? I second that question. Quote Link to comment Share on other sites More sharing options...
GrizzLee Posted January 7, 2007 Share Posted January 7, 2007 Ok, Here are some pics of my ADAM PS. Please ignore the crappy splice job as I wanted to use an actual ADAM printer power cord over the one they provided (It nestles in sideways and makes it more compact.. personal preference). Hope this helps -Lee Quote Link to comment Share on other sites More sharing options...
Murph74 Posted January 8, 2007 Share Posted January 8, 2007 Thanks for the pictures Lee. That is pretty much what I expected. I remember Eve fairly well, and their great line of prodcuts mainly after Coleco dropped system support. The power board itself is interesting, and I'm thinking it was just modified to be used with the Adam, or at least wasn't originally designed for hte Adam. Can you tell us what the model of the board is-- it looks like it's under the red capacitors along the edge of the board, but unreadable in the pictures. As for iriichi tsushin kogyo, they apparently made power supplies for the TI 99 also according to google. Bill-- there's really nothing technical to making this-- just using an arcade switching power supply and a joystick cable, it's just tighening a few screws. I'm sure someone could do it for you, but the cost of shipping alone would probably double the cost of the thing. I'd say the Power supply could be found almost anywhere locally (try craigslist wanted ads or a local arcade collector from newsgroups) for $10, and the joystick cable is only as expensive as you want it to be. What I don't know for sure is if the d9 sub connectors have a universal color coding or not, so you probably want to check each line to make sure it's goign to the right pin before connecting power to it.

Murph74 Posted January 14, 2007 Share Posted January 14, 2007 Just came across this link on related topic-- if you're going to make a PS for your CV, more is not always better. http://www.arcaderestoration.com/index.asp...A=647&CBT=4 Stick with a 15a or less PS. PM me if you guys really want one made for you. I'm thinking it can be done for about $40 shipped, but can't confirm that just yet.

A.J. Franzman Posted March 24, 2007 Share Posted March 24, 2007 What I don't know for sure is if the d9 sub connectors have a universal color coding or not, so you probably want to check each line to make sure it's goign to the right pin before connecting power to it. Most DE-9 joystick cables follow the Atari 2600 standard color code (pins 1-9 = white blue green brown red orange yellow black violet), but I've come across at least one that didn't (from the tiny Amiga Power Stick, the directions were swapped U<>D and L<>R, which is: blue white brown green red orange yellow black violet). Also, most Atari compatible joystick cables will lack the wires for pins 5, 7 and 9 (red, yellow and violet). If not sacrificing a joystick, just buy a 9-pin serial cable or extension cable (make sure it's "straight through" and not "crossover") -- this will definitely have all the wires.
