I have a GQ-4x and I'm trying to program a 27c4002 chip.

When I select that device the little window shows that an adapter is needed.  Why? the chip fits in the programmer?

I'm guessing that it doesn't work because I've baked these chips for over 30 minutes and they are still not reading blank.  :37- :37-

any ideas??

I had similar problem with other proms - if the prom is bad you will get that message -  see if the programmer IDs the prom - check a known good prom and see if that one IDs.

I bought 10 new ones and they all read the same.   I have put in a known good 4002 chip and I can read it  -  It looks like it reads it but I have know way of knowing if what I'm looking at is garbage or not.   

When I try to ID - I get that it's not supported on this device.    But I've gotten this many times before.

i think I have some 4002 - let me try and see what my burner does. will get back to you tomorrow.

Thanks! I'm upgrading to 5 now.  I was using 3.03 if that makes a difference.  :103-

Hey Munch,

I have that same burner but ended up getting the kit of adapters with it
and for the 4002 I have to use the ADP-O55 for it to work.


The kit also had adapters for plcc stuff too
for my spectrum's Think I paid $119.00 for the burner Full pack  kit with adapters

Tim

that is totally depressing

I got these with mine...

AND - to throw salt in my eye

this adapter is on backorder

Munch,

You will need this adapter to use for the 27c4002 e-prom. Although your programmer has the correct socket on it you need the adapter because it has chips on it that change the alogrithm to make it able to read and write to the 27c4002 e-prom.

Thanks k+ all around. How long does stuff stay on back order at
mcumall?

Munch,

Not usually too long. I believe they also make another adapter that you can use in place of the one I pictured. I believe the number is an adapter number 15 which you can view at mcumall.com but not too sure on that you may want to give them a call to verify. The phone number is listed on the site. I bought mine direct from them and it shipped from Canada quickly.

If you need help with something while you wait Munch let me know.

I bought this

I hope it works and leaves HK quickly.

I believe you will be ok with that also. Just not as easy to pull chips in and out of since it doesn't have the zif socket (zero insertion force) with the lever.

You'll see it in 6 months or less. I remember the last thing I bought from the tropical paradise HK.. took so long to get here I forgot I ordered it.

Munch,
Send me your stuff and I'll do it for you...be faster than that boat they send stuff on...

All he has to do is install some of these on that PCB....

Munch, although you probably figured it out by now, the reason that you need the adapter is because they are 16 bit chips. You can program 40-pin 8 bit chips without the adapter (although I don't know of any).

I'll have to get one of those adapters myself one of these days. I keep putting it off since I don't really need it yet for the machines that I have.

Try looking at the adapters page again as they used to have a few different types of adapters that did the 16 bit chips... Call them also as they are very helpful as well. Maybe they have one adapter in, but the other adapter is out of stock??

CaptainHappy :95-

Thank you all for the help.    Stout That's the funnest thing I've seen in a long time!  lol

I'll let everyone know when the adapter arrives.  It was $15 no shipping - it beats the mcumall's $29 (055board) with shipping or $39 (054board).    $30 is a lot for something that I may not use that often. 

Heard from Hong Kong!

"ship by airmail on 29-1-2010.10-21 working days."



Let's see how fast stayout's rickshaw is!

JD,

That depends on if it is a 50cc or 150cc Rickshaw. LOL!

I always smile when I pull... :96->>>

lol I'm not touching that!

Things that I have ordered from Hong Kong generally arrive in 10 business days, but you're on the wrong coast!  :72- :72- Add whatever time it takes to get from the west coast to the east coast -- probably another 5 business days -- in short, three weeks.

I need a faster rickshaw then!!!
CHAIN driven!!!!

I don't blame you! Stout's a nice guy, but this is definitely NOT the time to offer to lend a hand! :81- :47-   :208- :208-

This is the kind of Rickshaw I would want to drive to have a little room for hauling my hobby parts.

The boat arrived!!!!

 -  I don't know when it came though - cause I was away all week.

1/29 to 2/21 less a couple of days = three weeks: right on time. :89- :71-

Yeah, but where's the most important piece of info??? :103- :103- :103-


Does it work???? :30- :30-

C'mon, Munch, post up the results!  :88- :96- :5-

It's been so long, I forgot what he ordered!  :127- :200-  :208- :208- :208- :208-
Some kind of 16-bit phase-shifting Borg adaptive technology... :79- :130-   ...or was it a rickshaw? :128-

Qwesh-tun: If you order a slow boat from China, how do they ship it?  :81- :25-  :104- :97- :97- :97-

I think it might have beeen a slow boat... :127- :127-

You beat me by 12 seconds.  :96- :88- (see previous post edit, which I was typing while you were typing. :186-)

I'll definitely post pictures and let everyone know if it works.    I just couldn't stay awake and passed out last night. 

I seem to have that problem every weekend...

Well it doesn't seem to work.  I'm so tired I'll try again when I get a second but when I try to write it fails.

  I  remember hearing that exposing that window on the chips to light is one way to erase it. Cover the window with a label or piece of electrical tape and try to write to it again.  Dont know if it will help but it may be worth a try until someone with a better understanding sees your post.

Good Luck



 

I believe the GQ-4X does not need adapters to do a 40 DIP, post a question in MCUMALL forum about that chip and programmer, specifically.
They will usually answer quickly.
If you cant get it programmed I can help you out. send a PM.

I think the 27C4002 should be in other socket. 

It depends upon if the chip is 8 bit or 16 bit. Most of the regular eproms are 8bit, but the ones that we use for the base and key chips (27C4096 or 27c4002) are 16bit eproms, and they DO require and adapter for the GQ-4X. The adpater that I use was from the MCUMALL Folks, but i am not sure about the adapter pictured. I agree that he should post a question with the picture of the adapter on that forum.

CH :95-

I posted a question about the 4002/4096 on there.
It has me curious. I would love not having to run Sun/Oracle VirtualBox to do slot stuff.
my EasyPRO 90B does them without adapters, but it is limited to a 32 bit OS for now, until the low level drivers are done for 64 bit as well.

Munch, you probably have done all of this already, but I thought I'd add my two cents just in case. :96- :88-

You said that it doesn't write, but does it read?
Have you been able to confirm that you've inserted the adapter correctly? (I see exposed pin holes in the GQ-4X. Does the adapter use only 32 pins?) 
Are you sure that you've selected the right chip in the software?
If the right chip is selected and the 4X software indicates that you should have the adapter inserted, etc., can you then successfully read the ID of the chip?
The jumper looks like it is set correctly. Have you tried the chip in the other socket as Tilt suggested? Just for giggles, have you tried changing the jumper anyway?

I have good news and bad news.
 The bad news is the adapter from China doesn't work.   I don't know if it's just incompatable or broken - the result is the same it doesn't work with my programmer. 
The good news is I got the "official" adapter from mcumall and it works perfectly. 

It only took 4 days to get to me too.   :204-

Glad that you got it going finally. I really like the MCUMALL guys as they are very helpful, knowledgeable and fast!  :244- :244- :244-

This is great news Munch!
It now begs my question of course...
Why did you buy the blue one?  :96-
Was it like...cheaper than the MCUMall one?

I'm on my iPhone so I can't look up the
price but there were two reasons

The first was price I think $10 cheaper
the second and deciding factor
was mcu was on backorder - remember I started
this a month ago.

i am in the same pickle - I need to write some 27c4002 - clear chips for s2000.  beside the adapter from MCU - did you have to download anything as well?

nope- once I got the adapter - it was able to read and burn easily.  The cheap adapter on eBay didn't work.  The one from mpumall did.

thanks - ordered the adp55

Make sure you download the latest update for your  GQ-4X  from their website...I had the adaptor and didn't work until I had the  latest  update version for that exact  programmer.

I know this thread is old but it is the most relevant...
Where would be a good source for the 27C4002's?
These puppies are becoming "obselete" on most IC component warehouses.
I have a few games I want to back up...looking for 10 of these or similar for the S2000 base chips.

 :172-

Ebay reseller has them for  $2.60  ea /in lots of 10.    shipping incl.   

http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=280712780489 (http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=280712780489)

Those ST chips for the S2000 are one of the best I've tried.
Does anyone know off-hand if SST makes the "electrically-erasable" eproms?
I know they cost more but they are a breeze to use...

Also, it's been coming up here and there that the MXic company makes MX27C4096's that are "compatible" with the base chips? I've never heard of this company or know if these are "cross-referenced" anywhere to the STM27C4002's we normally use.
I'm thinking of trying some for backing up my personal games - have some insight on them?

The reason why I said that was because I've had some problems sometimes trying to UV erase the NM and AT chips.
( National or NEC, and Atmel brands. )
It could be that they were just done and had seen better days, I don't know,
but I seem to have erasure problems with those two name brands.

I've never had too many of these so I erase them a lot as
I'm constantly changing out kits for "experimentation, and educational purposes".

(Tell the truth Bunker! We KNOW you like games!)
That was my schizophrenic :200- personality thinking which oughtta be analyzed by the BAU...  :96-

Bunker  I get mine from China  http://www.buyicnow.com/fincat.php?cat=79   

Thanks guys!  :3-
A member PM'd me and I may have some different ones soon to try out.
Thanks for the help! Karma + storm!

Bunker,

Look at my picture in the link below where it talks about the chips for Neon Nites Base chip... you can use 27C4002, 27C4096, or 27C240 actually. (AMD does AM27C4096, and Hitachi does H27C4096 as well.)

No need to post that PIC twice you can just pop over there to see it.

CH :95-

Funny... I just noticed that for the Key Chip they do not mention 27C4002 which is just fine as well. Maybe they need to read a couple lines up! HA HA TYPO! :97-

no need to repost, or jump over to the other thread, just link the pics

Nice sheet!  :89-
But that documentation you've guys posted are for the I-Game?  :103-
I'm wondering if these MX27C4096 chips work for the S2000's as base chips utilizing the GQ-4X unit?

Would that be a good assumption since the GQ-4X supports the other name brand chips
and the I-Game sheet doesn't dare mention any chipmaker? 

Bunker   If you go to this China-man's site, you leave there with the impression that they are compatible !! ( First two lines )   http://www.buyicnow.com/search.php?searchx=MX27C4096&zl=0

He's on vacation but will be back Sunday.
I just talked to his "secretary" this afternoon...( she sounds cute...lol)
I will place an order with him soon and thanks for the great link Buzz!
I want to see if a couple of the 27C4096's to experiment with.

Someone on this site posted about them and I kind of think it was Foster.

If you called China today your lucky you got hold of anyone cause they are right in the middle of their New Year.

She sounded a little... uh...happy? lol
probably a small home-run biz.

27c4002 and 27c4096 are exactly the same...Use them all the time, have for years. Been a secret that they work. nobody looks for them. Just picked 50 brand new off e-bay for $39 shipped from the USA in 3 days. So did Ford..I tipped him off to them.

Thanks for verifying coors!  :3- :244-
Are yours the MX ones?
Have you tried the MX brands in the GQ-4X because there's no mention of that chip at the MCUMall.

MX are Macronix?   AMD am27c4096 or St (SST)m27c4002 are supported....

Wayne,

Thanks for the wise photo link post, I never thought of that, and was in a rush! :131- :244- :259-

Others,

I have used the 4096's for a long time as well. Also I have programmed 4096's while the programmer was set for 4002's and there were no problems. Works fine on S2000 and iGames as has been said indirectly.

CH :95-

If that one is on backorder the get ADP-054

http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4289 (http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4289)

I like it better since it has 2 ZIF sockets

CRAP, that one is on back order as well -- Sorry

They have them listed on eBay.
