HI

I've bought an EPROM burner as above and just checking out how it works....

I have managed to combine U1 & U2 codes in DOS from the downloaded 2716 codes on the IPDB, and created a new U2 Binary file. This U2 code verifies against the 2732 U2 fitted in my Bally Kiss (EPROM bought elsewhere). I cant however get the IPDB U6 code to verify against the U6 2732 in my kiss. I read something about doubling up on code, can anyone help me with the DOS command to convert the IPDB code file 720-30_6 into a working 2732 code so it verifies against the one fitted in my working Kiss.

cheers
Brian

Copy /b u6.716+u6.716 u6.732

Copy /b u1.716+u2.716 u2.732

I make batch files (.bat) in notepad instead of using command prompt. I find that easier.

This worked for me....

COPY /B Protext1.bin+Protext2.bin Protext32.bin

In line with mcluvin:

COPY /B U2ROM.716 + U6ROM.716 U2COMBO.732

I think Andrew is converting two 2716's at U2 and U6 to two 2732's at U2 and U6.

This is incorrect.

Kiss ROMs are originally three 2716 sized ROMs at u1, u2, and u6. When using 2732 EPROMs, you combine U1 and U2 together into one 2732 sized eprom at u2.

copy /b u1.716+u2.716 u2.732

For 2732 at u6 you have to double up the 2716 sized rom.

copy /b u6.716+u6.716 u6.732

Send me you email address i can send them to you.

Indeed I am incorrect. I didn't read the original post close enough.

U6 could be a 2716 with 2732 in U2 position if you have jumper 16A-18

cheers for all you help I have managed to combine files now - i cant seem to write the file to the EPROM?

I am using an AMD AM2732A, so I have set this as the device, I load the .732 file into the programmer but it comes up with the following error:-

Write failed, Address=0x000000, Buffer=0xB9 Device=0xFF

I have erased the chip using a UV device and the Blank check says "blank"?

any help much appreciated

forgot to say i do have an external power supply connected

Be sure the chip is inserted correctly.

Be sure you have locked the lever.

If it fails again, blow the socket clean, slide the chip to one side of the socket and try again.

You could also have a bad chip that blanks ok but can't be written. Try a different chip.

I just did three AM2732A chips with a GQ-4X no problem.

Got the chips from Dave Astill pre-programmed for a Kiss, erased them for 5 mins? Checked they were blank and then no luck. Is there any offset setting or anything on the settings I should use?

I'll try again reseating them in programmer

5 isn't usually enough. I've had 2732s get errors on writing after 15-20 minutes of erasing. Try erasing for 30 or more minutes. Fixed the issue for me both times.

Tried again and all good thanks

Do the blank check with the burner, that tells you all.

Also, if you still have writing problems after all that, try lowering your write speed.

Quoted from Matt_Rasmussen:

I've done the blank check before with positive results and still the chip didn't burn. I re-erased, then tried again and it worked. Not sure why, but was glad I didn't have a useless eprom.

General question on this burner, when you see the 'plug it in' message, and don't, but the burns wrote and verify fine it should be good right?

I seem to have sorted the art of burning Bally -35 ROM's is it the same process from :

Bally sound ROMs (ie: double write?)
DE CPU ROMs (Double write or just write once?)

The burner has lots of features / settings I havnt touched yet, not sure if I need to for pinball chips so any help and advice much appreciated, including when I need to or don't need to double write

Many thanks
Brian
