Shawn Posted June 8, 2012 Share Posted June 8, 2012 (edited) put this 16k of junk data at the START of the binary after you have signed the 48k worth of code. copy /b junk16k.bin + 48k.bin 48kwjunk.bin junk16k.bin Edited June 8, 2012 by Shawn Sr. Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 8, 2012 Author Share Posted June 8, 2012 I don't think my GQ-4x programmer software has the option to do that. Quote Link to comment Share on other sites More sharing options...
+Mitch Posted June 8, 2012 Share Posted June 8, 2012 Do you have a hex editor? I use ultraedit32 myself. WIth a hex editor open the bin file and insert the desired amount of blank space. If you want to use Shawn's method you can just paste his 16k blank file to the front of your bin file. You should be able to do this from the Windows command line as well. Something like: copy junk16k.bin+48kgame.bin 64kgame.bin I beleive that's the correct syntax, it's been a while. Obviously substitute your own game file name for the 48kgame file name.

jwierer Posted June 9, 2012 Share Posted June 9, 2012 I don't think my GQ-4x programmer software has the option to do that. You just do what Shawn suggested from a Windows commandline. -Jeff Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 I made the 64k binary successfully, however a 64k EPROM won't work on a 48k cpuwiz board will it? Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted June 9, 2012 Share Posted June 9, 2012 Yes, it is made for 27C512's. Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 so will a 27512 work in place of a 27c512? Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 I think maybe the EPROM is incompatible. Here is a pic of the board. Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 Here is a board with nothing on it. I say 74LS02. Quote Link to comment Share on other sites More sharing options...
PacManPlus Posted June 9, 2012 Share Posted June 9, 2012 so will a 27512 work in place of a 27c512? Yes Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted June 9, 2012 Share Posted June 9, 2012 Dude, you have a 74LS21 in there, not a 7402/74LS02/74HCT02. Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 (edited) Fu%&ers at Jameco sent me a non-compatible substitution I guess. I was a dummy and ordered the wrong thing by mistake. Edited June 9, 2012 by Yurkie Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted June 9, 2012 Share Posted June 9, 2012 74LS21: That chip doesn't even remotely do what the 74LS02 quad 2-input NOR gate does. I am shocked Jameco would do something like that. I should have just sent you a few of the 74LS02's with the PCB's. Sorry. Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 Turns out it was my bad. I ordered the wrong part by mistake. I looked in my order history. I love Jameco. I just placed an order for 25 74LS02s Now I need to buy some more of your high quality boards! Fantastic board quality! Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 Damn it is a bummer to spend hours messing with something, only to realize one was an idiot and is using an incorrect component. Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted June 9, 2012 Share Posted June 9, 2012 Yeah, Jameco is awesome for older parts, I used to live very close to them and could actually just go to their warehouse store-front. That is why I was saying I was surprised, they know their sh*t, if you know what I mean? Glad you like the boards. Quote Link to comment Share on other sites More sharing options...
+Yurkie Posted June 9, 2012 Author Share Posted June 9, 2012 Yeah Jameco is fantastic. I would be always broke hoarding components if I lived down the street from Jameco. Quote Link to comment Share on other sites More sharing options...
