New Programmer baby born at my house...

[stayouttadabunker]

Whoops...I did it...went out and bought the GQ-4x True USB Universal Programmer.
I want to back up all of my collection of S+ chips.
First thing I did was mess around with the installation of USB stuff to connect the programmer to my computer.
Took a while but followed the help instructions to a T and got it installed correctly and verified connection.
Then I did a  USB "voltage test" to see if my USB ports would sufficiently power up the programmer.
Everything passed! this is the results of the test>>>

I've got a lot to learn...

[stayouttadabunker]

Okay, put in a blank AMD M27C512 EPROM to see if the chip was indeed blank.
Ran the programmer first to ID "read" it then I ran a "blank check" this time to to check it out...sure enough, here are the results...man that's fast!

ID check OK
Reading...Code Memory
Elapsed time: 2.90 seconds.
Read completed.

ID check skipped
Blank checking...Code Memory
Elapsed time: 2.98 seconds.
Chip is blank


I'm going to bed, can't wait to play some more tomorow!

Oh NO! Don't tell me you're burning Z80 replica CPUs and selling illicit copies of the TRASH-80 level I? (Radio Shack TRS-80)   
I'll take one with 4K of RAM and a cassette deck please.

(in a slow, southern drawwl...)   You guys crack me up....

Boy did I ever blow it....I tried to make a copy of my favorite game SS4667 Double Cherry Bar 2CM 85%. This SS is  burned onto a Texas Instruments TMS27C64 EPROM. I'm sure I corrupted my original Eprom by putting the chip in notch backwards and turning on the power to only get a "62-1" error code (Bad Data Prom)   
 
1). I first "read" the eprom then saved it to "My Documents". I have, at least, a saved copy of it. 
2). I did a "blank" check with a new blank AMD AM27C512...fine, programmer displays it as blank. All code memory has is "FF"'s.
3). Then I punched in "C000" into the File Offset box and "C000" into the Device Offset box. 
4). Uploaded my saved file of the SS4667 in to "Code Memory" display on the programmer. (Lots of written code, noticed "ss4667" in the code way down on the right hand side where there's mostly periods typed in.
5). Check marked the "Write" box and "Verify" box on the programmer.
6). Ran the programmer... Got checksum:0xA6DO and "Device is verified" message on the bottom of my screen.  Unlocked the ZIF lever, removed the newly burned Eprom,  and exited from the programmer software.

I put the newly burned copy in my game and got error Code "62-1" again...what am I doing wrong? In my excitement to do a swap,(To check and see if my board is okay) I took out the burned Eprom, installed the original SS in notch backwards and got a "Code 62-1"  

Can I re-burn a new blank using my saved file of the SS4667?
The saved file when "read" displays Checksum:0x86D0
The blanks "read" Checksum:0x0000.
I know I probably didn't do it right the first time. 
I think I'm doing something wrong on the File and Device offsets settings. 
I noticed that the code memory is only about half as what is written on the original and saved files. Is that because of the differences in chip sizes? 

Any help of course is greatly appreciated ! Thanks.

I may have sent that same surprise to him! 

[stayouttadabunker]

Whoa there Nellie!!!! I'm getting swamped with Z-80 replicas and Trash 80 Level 1 software!!!!!(just kidding)
I would like to take this moment to deeply thanks everyone for sending me...you know...love? 
I'm gonna be online all night now trying to thank everyone for their "contributions"...I will (when I get better at this)
send all those who helped me a "little" gift...just get that StatFreak to stop pickin' on me!!!!

I think r273 helped me find out what I was doing wrong.....He sent me some of his personal programming notes which I feel is very important to have as a reference to assist a newbie programmer like me. I will ask his permission later on to have it edited so that it could be presented as a valuable tool in helping someone make a backup copy of an eprom that can be used in various games and equipment such as pinball, arcade, DBV's and of course slots.

On the 4th step of the second paragraph, there's a procedure to "change A-B to B 0xC000 as B address and 0x2000 as the size". I totally overlooked this because of the simple reason...I don't know what the nuggets this is all about and what it's used for... So I neglected in reading further about it and skipped the step in the GQ-4X programming instructions.
Instead, I typed in "C000" in both dialog boxes hoping to burn a perfect backup copy of my game.
That may explain why the eprom wouldnt work on my machine and shoots me a "62-1" error code instead.
I may be wrong, but I will make another attempt to make a copy before the evenings over....it's a good thing I bought a dozen of these for my learning ("I'm gonna say...practice") rounds.
I will succeed in accomplishing my goals of backing up my collection and repairing my game!

Hmmm.   I thought I sent you the same thing everyone else did, but after reading your last post, I realize that what I sent you might be a bit different..
Check your email.

Got it, thanks SF!

After installing the newly burned backup (containing checksum:0XA700, and "verified" but not "Locked") onto a 16MHz board, I'm getting that dreaded "62-1" error code (means "Bad Data Eprom").
Ther are no jumpers on a 16MHz board whereas, the 10MHz board has a jumper on both the reel & game sockets.
I'm thinking of putting the copy in a 10MHz board instead.
Normally (because S+ reel eproms are made with 27C64 chips) the jumpers are jumping the two pins facing the dipswitch side of the board.
Should I move the reel socket jumper towards the transformer side ,leave it where it is, or pull out the jumper altogether?
Whoever has the correct answer for this: wins a free machine from Navinut...

[jay]

I am sure I am disqualified from this contest because I am staff (thankfully ......)

My conjecture is that your error could be because your chip is not fast enough. Your suggestion of putting it in a 10mhz is probably a good test.

[stayouttadabunker]

This is the specs on the blanks I'm using...is it fast enough to use for reel eproms on a 16MHz board?

[jdkmunch]

On the other thread I was told that a 70ns chip would work so I think your 55ns should be fine. 

[StatFreak]

For a 16MHz S+ I'm pretty sure that anything faster than 120ns is fine. (I think that even 150ns will work, but am not sure). 55ns is blazing for the S+; the chip is probably bored.

All kidding aside, when you burn an SS reel chip (8KB file for a 27c64 chip) onto a 27c512, you must burn it starting at the chip offset of 0xc000 for the S+ to read it properly. If you've done it right, when you look at the hex readout of the finished chip, everything will be blank (0xFF) from 0x0000 to 0xbfff, the data will start at 0xc000 and stop at 0xdfff, and 0xe000 to 0xffff will be all 0xFF (blank). The data at 0xc000 should match the beginning of the file.

I would like to add: If you use a 27c512 or SST 27SF512 in a S2000 or Vision the C000 offset will not work.

The reason the S+ needs the offset is on a 27c64 they apply Vcc to Vpp and the Programming Pin which corresponds to C000 A15 & A14 Logic level 1 on a 27C512. Where the S2000 just keeps unused pins at logic 0

Foster,
Can I send you a copy of my GQ-4X software?
I need to know what to type into the dialog box.
It's too hard to explain but easier for you to see if you peruse the software yourself.
You'll see what I mean.
I've sent this software to Statfreak and r273...no one's been able to figure out how to burn a copy and get it to work without getting that dreadful "62-1" error code on my S+.
What is this box for ?

[stayouttadabunker]

That looks like you can fill an area with any value (FF)  -  or forcibly erase the chip.

[stayouttadabunker]

Yes and No,
These AMD  AM27C512 Eproms can only be erased when the paper is removed from the window and submitted to UV light.
You need EEproms to "Electrically Erase"or "Electronically Erase" with this dialog box.
You CAN however, add/ or erase whatever file value you want into the "Code Memory" data box area.

[StatFreak]

Actually, I haven't had a chance to install the software. I apologize. 

You won't want to mess with the 'Fill' command.

I believe that what you need to do is to put 0000 in the file offset box, and c000 in the device offset box.

It that doesn't work, try it the other way.

[stayouttadabunker]

I tried this...the first pic is the dialog box for "File and Device"  offsets.
The second pic is the blank Eprom configured to be written with an offset of 0XC000...
Should I change the "File" offset before I burn another attempt?

No. Did you already burn one this way and try the chip? If so, and if failed, then try setting the file offest to c000 and the erpom offest to 0000 (but I was pretty sure this first way would work).
