Eprom Programmer Hell - Death by 27c4002

[jdkmunch]

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. 

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.

[jdkmunch]

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

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

that is totally depressing

I got these with mine...

[jdkmunch]

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.

[jdkmunch]

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

[opman]

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.

[jdkmunch]

I bought this

I hope it works and leaves HK quickly.

[opman]

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.

[Brianzz]

I hope it works and leaves HK quickly.

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...

[KirkLasVegas]

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

[StatFreak]

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.

[CaptainHappy]

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??

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!

[opman]

JD,

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

[stayouttadabunker]

I always smile when I pull... >>>

[jdkmunch]

lol I'm not touching that!

[StatFreak]

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