Hi all,

I am new here and wanted to know if there is an EPROM/IC burner at TAMI ?

Thanks,

Gal

We have a bus pirate that should cover most of those needs.
It's on the box labeled "bus pirate" on the elec table shelf.

there is actually an eprom burner with several vintage IC's having clear
windows on them
i think it was last in the white shelves on left back wall of hackerspace,
around the 3rd/4th shelf
this is ancient tech btw , maybe not what you were looking for??

Hi Jr,

This is what I am looking for,
I just don't want to buy a new one and using it every two years.

I know it is some sort of ancient history but still, there are many working
things with burned IC's that needs to be replace.
I have some work parts that there are a few PIC chip's that I need to
replace but the manufacturer will not sell them only
a new set that cost about 600 Euro.

I will check it next time I will be at TAMI,
Thanks

Can you look to find an EEPROM Pic to replace your eprom pic?
Presumably this is an easier thing than

I have two programmers - one is an old Labtool 48, which requires Windows
XP at most and stopped receiving updates years ago, and the other is a
newer chinese TL866 (
http://www.eevblog.com/forum/blog/eevblog-411-minipro-tl866-universal-programmer-review/).
They are not at TAMI, but if you have specific needs maybe we can arrange
something. I also have an old EPROM eraser (with a UV lamp), but I've never
checked it.

Ahh... the old days... When I was really young (high school, in the
mid-80's) I used to work on various commodore hardware, mostly adding
Hebrew characters to commodore dot matrix printers. I had a Promenade C1
programmer for my C64 (
http://mikenaberezny.com/hardware/c64-128/promenade-c1-eprom-burner/) , and
my debug cycle was a function of the # of EPROMs I had at hand, and the
cycle time of the EPROM erase UV lamp I had :-)

And remember, you can always write a '1' bit to '0' but not the other way
around, so I would make incremental changes and test them.

I think my biggest achievement was neutralizing a checksum check at the
beginning of the EPROM, with the firmware written for an obscure NEC 8-bit
controller. I fed the mnemonics and opcodes into a primitive C64 database I
had so I could sort them by opcode and have a more convenient table for my
pencil and paper disassembly.

Udi,

I would really like to sit with you some time in the close future and talk
about that
or even try to read the info from some pics I have.

When you will have the time.

Hi Gal,

I don't visit TAMI very frequently, I'm mostly active on the mailing list
(not facebook).

As for your PICs, it would help if you specify the exact model you have.
Do these have a code protection option, and do you know if your PICs are
protected?
If yes, I don't think I can help much (there are techniques for bypassing
that, but they are not straightforward, and I'm not an expert on the
subject).

It's not a question of passwords. Usually when a Micro is read-protected,
it simply cannot be read back, period.
The only way to crack these kind of micros is either via an intended
backdoor in the firmware, unsecure code (buffer overflow on your micro??) -
both are unlikely, but the common tricks are to play with the power supply.
sometimes running it on a marginal voltage can be used to bypass the
security uses.
In extreme cases, you can find examples where people have decapped the IC
(using hot nitric acid), shielded part of the die and the exposed it to UV
to clear the security fuse.

Hardcore :-)

I will check the data sheet of the chip,
Ibeleive it needs to be written there.

I think I will also order from Ebay the one you said you have
I had seen the TL866 at about 50$

Thank you very much for the help.

there is actually an eprom burner with several vintage IC's having
clear windows on them
i think it was last in the white shelves on left back wall of
hackerspace, around the 3rd/4th shelf
this is ancient tech btw , maybe not what you were looking for??

What IC do you specifically need to burn?

Hi all,
I am new here and wanted to know if there is an EPROM/IC burner at TAMI ?
Thanks,

notice that there are two models, the TL866 and the TL866CS which lacks the
ICSP programming port, and is cheaper by 10$-15$. there is a hack for
converting a CS model to noon - CS, but since the hack is at least 6 months
old, the manufacturer may have already implemented countermeasures. so if
you don't need ICSP programming, want to save a few bucks, and be
adventurous, pick up the CS model.

Hardcore :-)
I will check the data sheet of the chip,
Ibeleive it needs to be written there.
I think I will also order from Ebay the one you said you have
I had seen the TL866 at about 50$
Thank you very much for the help.

Post by Gal Bazel
Thanks Udi,
I will check the numbers of my PICs
and I really don't know if they have password,
I hope not :-(

Hi Gal,
I don't visit TAMI very frequently, I'm mostly active on the mailing
list (not facebook).
As for your PICs, it would help if you specify the exact model you have.
Do these have a code protection option, and do you know if your PICs
are protected?
If yes, I don't think I can help much (there are techniques for
bypassing that, but they are not straightforward, and I'm not an expert on
the subject).

Udi,
I would really like to sit with you some time in the close future and
talk about that
or even try to read the info from some pics I have.
When you will have the time.

I have two programmers - one is an old Labtool 48, which requires
Windows XP at most and stopped receiving updates years ago, and the other
is a newer chinese TL866 (http://www.eevblog.com/forum/
blog/eevblog-411-minipro-tl866-universal-programmer-review/). They
are not at TAMI, but if you have specific needs maybe we can arrange
something. I also have an old EPROM eraser (with a UV lamp), but I've never
checked it.
Ahh... the old days... When I was really young (high school, in the
mid-80's) I used to work on various commodore hardware, mostly adding
Hebrew characters to commodore dot matrix printers. I had a Promenade C1
programmer for my C64 (http://mikenaberezny.com/hard
ware/c64-128/promenade-c1-eprom-burner/) , and my debug cycle was a
function of the # of EPROMs I had at hand, and the cycle time of the EPROM
erase UV lamp I had :-)
And remember, you can always write a '1' bit to '0' but not the other
way around, so I would make incremental changes and test them.
I think my biggest achievement was neutralizing a checksum check at
the beginning of the EPROM, with the firmware written for an obscure NEC
8-bit controller. I fed the mnemonics and opcodes into a primitive C64
database I had so I could sort them by opcode and have a more convenient
table for my pencil and paper disassembly.

Hi Jr,
This is what I am looking for,
I just don't want to buy a new one and using it every two years.
I know it is some sort of ancient history but still, there are many
working things with burned IC's that needs to be replace.
I have some work parts that there are a few PIC chip's that I need
to replace but the manufacturer will not sell them only
a new set that cost about 600 Euro.
I will check it next time I will be at TAMI,
Thanks

It's not a question of passwords. Usually when a Micro is
read-protected, it simply cannot be read back, period.
The only way to crack these kind of micros is either via an intended
backdoor in the firmware, unsecure code (buffer overflow on your micro??) -
both are unlikely, but the common tricks are to play with the power supply.
sometimes running it on a marginal voltage can be used to bypass the
security uses.
In extreme cases, you can find examples where people have decapped the
IC (using hot nitric acid), shielded part of the die and the exposed it to
UV to clear the security fuse.

we have a fancy pic programmer at the top leftish bin in the wooden hive.

Jr, that thing you mentioned is an eprom uv earser.

Hi Udi,
I am looking to read and burn data from PIC chip like this
http://pdf.datasheetcatalog.com/datasheets2/16/1643295_1.pdf
and burn CMOS Flash like this
http://pdf.datasheetcatalog.com/datasheet/macronix/MX29F040PC-70.pdf
and also some eprom's
