    Well I tried 2 games, both get to where i need to press fire to proceed. pressing every key there is gets me no where

     

    A bad CIA perhaps? There are 2, one of them is for the keyboard and joystick. Maybe swap them around and try again? Not sure if they are socketed or not.

    ... theres a wire thats not hooked to anything on one end but idk where its supposed to go?

     

    ...

     

    Is this wire coming from the keyboard? There is a ground wire that goes from the keyboard to a screw located on the floppy drive. It's a braided silver color wire.

     

    Maybe more of a description of this wire you are talking about will help.

    When I first got my Amiga 500 (it was tested working before I bought it) I didn't have any Workbench floppies or games. I used an HxC floppy emulator to boot from and then create a real floppy with an external drive.

     

    I just plugged up my HxC where the internal drive goes and downloaded an ADF (converting it to HxC format of course) of Workbench and put it on my SD card. I already had an HxC though because I used it with my TRS-80.

     

    I'm sure there are other ways to get going too.

    Ok all I have is workbench 1.2 & 2.04 disks guess I gotta try find a disk online and see if I can get my floppy emulator to work :P

     

    I should clarify, most games will just boot on their own, you don't need Workbench. Also, you should be able to boot 1.2 Workbench, just not that 2.x since you don't have a 2.x Kickstart ROM.

     

    If you can't get the WB 1.2 disk to boot or maybe a game disk, then I suspect something else is wrong. Unless of course it's just that those disks you have are bad.

    So I hooked it up and the caps lock lights up and external drive light comes on but thats it. opened it up and looks like the power LED is cracked and theres a wire thats not hooked to anything on one end but idk where its supposed to go?

     

    the internal disk drive works now, guess the cord came loose in shipping, so now that drives light comes on and when you put disk in it trying to access it but still nothing on screen

     

    Does the screen display a certain color? Or does the keyboard light flash? The Amiga will provide you with some troubleshooting clues:

    Who has one?

     

    Opinions?

     

    Can it be used with Game Genie?

     

    Price new and used?

     

     

    I have one and can recommend it. I don't use Game Genie so can't say anything about that.

     

    For US based folks I can recommend: http://www.stoneagegamer.com/everdrive-md.html

     

    They shipped rather quickly once the order was placed and the cartridge I received was well made and works great!

     

    I purchased the "Mega Everdrive" from a place in Canada that I can't recommend, unfortunately the name escapes me at the moment. Took them forever to ship and the quality wasn't there like the one from Stone Age Gamer.

     

    Update: The place in Canada I can't recommend is called gamersection.com.

    Cool, thanks. Didn't know such a thing existed, but I'm rather new to the Amiga world.

     

    I found this to describe what it is in case others are finding this thread:

     

    "

     

    The A1000 phoenix was a subscription funded replacement motherboard for the A1000, ie a totally new 3rd party motherboard which was designed to fit into the A1000 case. It was designed and manufactured by Phoenix Microtechnologies in South Australia (circa 1991). It was a totally enhanced A1000 motherboard. It came with the ECS chipset, Kickstart 1.3 (on ROM) and 2MB of RAM. Depending on your configuration preference, the RAM was either configured as 1MB Chip and 1MB Fast or as 2MB Chip. It also had an optional SCSI-II controller on the motherboard. Every motherboard has the SCSI header present, but it was optional because it required the purchase of the SCSI PAL Chip and EPROM. The A1000 phoenix also had a single Zorro II slot, but because of the limitations of the A1000 case, any Zorro II cards needed to be mounted in an external unit. An a2000 video slot was also added to the motherboard as well as a battery backed-up clock. The motherboard could either be installed manually by the user, which required the retention of some chips from the original motherboard (Paula, Denise, CPU), for installation on the new motherboard or users which lived near the manufacturing facility could have their motherboard replaced by Phoenix Microtechnologies themselves. There is estimated to have been between 500 and 1000 production units of the A1000 phoenix made.

    Thanks, looks good! Now I will not be afraid to use my NOS A1200 since I can find a replacement board rather easy if/when that time comes.

     

    Of course not "all" the options I have currently will work on the "Reloaded" board it seems, so far anyway. None of them are showstoppers. I'm sure the details will change by the time he actually produces something.

    There was a difference in the 64C models. Do you have the skinny board 64C or does it look like the size of the regular 64 but in the white case of the 64C?

     

    Also, here is the service manual for the 64/64C:

     

    http://www.bombjack.org/commodore/commodore/C64-C64C_Service_Manual_314001-03_(1992_Mar).pdf

     

    You'll find some additional troubleshooting information:

     

    Per the manual. For blank screen on power up:

     

    Check External Power Supply
    U4 (KERNAL ROM), U17 (PLA)
    U7 (6510 MPU), U3 (ROM)
    U8 (7406 IC), U19 (VIC II)
    U9-U12 (4164 RAM)
    U21-U24 (4164 RAM)
    VR2, CR4, VR1

     

    You have to be careful with putting ICs from a regular 64 into a 64C. Depending on the board revision, you can damage the ICs. For instance, the SID 6581 used 12v where the SID 8580 is 9v. Commodore changed to HMOS with 85XX chips which uses less voltage.

    I found another means that may be of use to someone:

     

    The SAMS book "Commodore 1541 Troubleshooting & Repair Guide" has a listing for a BASIC program to assist in repairs/cleaning. It can turn the motor on/off, bump the head, move it half tracks etc.. Not that long as well.

     

    It's on page 30 (Fig. 3-1). You can download a PDF here, but it's very hard to read:

    Hi, a blank screen can be a result of many different failures unfortunately.

     

    Take a look at some of these symptoms and what might be their cause: http://personalpages.tds.net/~rcarlsen/cbm/c64/c64c-ic.txt

     

    Failed or failing RAM is one of them. Check the ICs to see if any are hot.

     

    Maybe download a repair manual or two from this site: http://www.bombjack.org/commodore/books.htm

     

    A Dead Test cartridge is useful in situations like this. If you don't have one, an Ultimax type cartridge can be used to see if the issue is bad RAM or ROM. A failed CPU can result in no video as well.

     

    I answered a simliar quesiton on the lemon64.com site today. Not sure if you are the same poster.

     

    Good luck!

     

    Update: Here is a list of Ultimax cartridges in case you have one:

     

    Avenger, 1983
    Billiards,1983
    Bowling,1983
    Clowns, 1982
    Gorf (MAX), 1983
    Jupiter Lander, 1983
    Kickman, 1982
    Lemans, 1983
    Mole Attack, 1982
    Money Wars, 1982
    Omega Race (MAX), 1982
    Pinball Spectacular, 1982
    Radar Rat Race, 1982
    Road Race/Night Driver, 1982
    Sea Wolf, 1982
    Slalom/Ski,1983
    Speed / Bingo Math, 1982
    Super Alien, 1982
    Wizard of Wor (MAX), 1983

    Yes, j12 is 3.3v power out, there is another connector in the bottom that is 5v input.

     

    Actually, vga is not the point with this device. You will get 720p hdmi out, so i did not thought vga with scan doubler important. If it's needed a simple device can be hooked up between j14 and j16 to do the scan double. To be honest I do not have a lot of knowledge about this.

     

    Regards,

    StaringL

     

    Thanks for the information. Will look forward to the final result.

    Interesting... that routine is:

    F982 AD 00 1C LDA $1C00
F985 09 04    ORA #$04     turn drive motor off
F987 8D 00 1C STA $1C00
F98A A9 3C    LDA $3C
F98C 85 48    STA $48
F98E 60       RTS

    This is from Abacus Software's Anatomy of the 1541 Disk Drive. Notice how the routines are reversed from what we expect and observed behavior. Maybe an error in the book's disassembly.

     

    I've never really taken a look at the disassembly of this before.

     

    You can turn the motor off with:

     

    OPEN15,8,15:PRINT#15,"M-E"+CHR$(232)+CHR$(249):CLOSE15

    I will be receiving my Zoomfloppy today. What software would you guys recommend using to download from the internet to the floppy drive?

     

    Are these thingies pretty easy to set up?

     

    I am getting my 64c motherboard back from Ray today as well - things are looking up for my C64 endeavors.

     

    -Ralph...

     

    Nice!

     

    I just use OpenCBM: http://root.org/~nate/c64/xum1541/index.html

     

    http://root.org/~nate/c64/opencbm-ZoomFloppy-2.0-i386.zip

     

    http://root.org/~nate/c64/ZoomFloppy-Manual-2.0.pdf

     

    For Windows of course.

     

    As far as setup goes, not much really to it. You'll need a USB cable where one end is a mini-USB and then of course your IEC cable that goes to your drive.

     

    Just make sure you read the PDF manual, because it's important you follow the proper power up/down procedures for it.
