Qpc Simm Burner Help Needed

[rjpohl]

I cab read IGT PXL's but I can't write to them.  I need to know if the "write enable clip" I have is the correct one for IGT.  The one I have has "Toshiba" written on it.  Does anyone have a picture of the proper clip for IGT?  Any part numbers on clip would be helpful too.
thanks

Here's the jumper for all SIMMS (except Toshiba).  I'd just modify the one you have.  Toshiba SIMMs are pretty rare.

thanks Tilt I think that's what I'll do.

The taps broke off when i tried to un-solder and rebend.  Mouser has the part (341-012-520-202) but has minimum of 25 pcs to order.  Anyone know where else to try and get the clip?
thanks

That's a bummer.  You can order single quantities from Digikey.

thanks, I'll give them a try.

I have been able to connect the the 2 sets of pins on the write enable clip but I still get an error when I try to write to the simm.


Simm 0 (r/o)   0x0              16 MByte  (this line is there when I start)
00                  0x0              32 Mbit (2x8bit)   ERROR     
01                  0x80000       32 Mbit (2x8bit)   ERROR


any suggestions, dip switch setting???

The (r/o) means read only.  With the write enable plug on the simm hit the detect button and see if that goes away.  If it still shows (r/o) you may have a bad SIMM, try another one and see if it works.  I normally set the DIP switches for that the SIMM card will be when in the machine. e.i. all off for a sound SIMM.

[rjpohl]

You were right, tried a different simm and the r/o was replaced with a 0.  I was able to write, read and erase that simm.


On the igt simms there's usually a 4 digit number inside parenthesis, is that the checksum and if where can it be found after reading simm?


thanks

If you're referring to the original IGT label, yes that's the checksum. 

The QCP software doesn't show the checksum for the file, so I don't know how you'd find it if you didn't know what it was.  You can use the verify function to verify that the file in memory matches what's on the SIMM though.
