Hardware required? Works on basic PCs even an old IBM PC with an Intel 8088 running at 4.77 mHz and anything later..
What is the correct pin-out of the wall adapter or I need to get a wall wart (power adapter ) to run over seas, what kind do I need? ? Look here The wall adapter for the 'Pocket programmer 2' is now center positive (don't interchange - but the new one won't get hurt by backward voltage!) PRogrammers with an LED can have either polarity.
Does It need AC power for operation? That is, will run off plain DC power, like that from a car battery? Normally the pocket programmer uses the included DC wall adapter. With our cigarette adapter you can run it off car voltage, Don't try to just make a cable - the 12-14Vdc of a car have been known to break the programmer. you can also run it off a battery (just don't go much above 12 volts
How do I prevent static damage while handling EPROMS? - Read this
Why does the voltage of my power pack read so high? It is normal for it to read high without a load - it is rated at 9Vdc with a 300mA load.
Does It Work with all kinds of parallel ports? All but USB parellel port converters. unidirectional, PS/2, Note EPP, ECP power management (both CMOS and config.sys) should be turned off.
How fast is it?Very fast! 1 1/2 sec per K byte even with an old 286 running at 8 mHz!
How can I check the Vpp
voltage? start the program, select a device, and
highlight the
Vpp button. Then press 'T'. You can then press the Vpp button and
change it to the value you want to test (you must
press the new Vpp button at least once. You will want to put paper
clips in the pin holes for the pins you want to
measure as most meter probes won't reach. In the DOS program, select
function 88. Normal ranges for Vpp are as
follows:
12.5V - 12.7 to 12.9
21V - 20.5 to 21.5
25V - 24V to 26V
The
Modification for very old PP II
is as follows:
Remove the Dc-Dc base resistor (1.5K or 2.2K). This resistor
is located by the Power connector between
the 39 ohm resistor (Orange-White-Black) and the 1N914 Diode. Replace
with a 2.2K (Red-Red-Red) from the base
of the 2N4401 or MSPA06 Transistor (Middle Leg) on the bottom side of
the board to Pin #19 of the 74HC374
located by the 7407. This will only be affective when the software is
running or the 74HC374 latches Low on power
up.
Finally, run the software. Click on the Vpp voltage then type a "t". Use the test Vpp menu to adjust the pots to provide the correct Vpp for each voltage setting.

Start Addressto include Buffer Start.

Most of the time you will never have to touch any of these unless you are splitting ROMs or pasting together files.
Buffer-start Automatically set - but you can change where the software thinks the beginning of the binary file data gets loaded. The buffer-end is always the buffer-start plus the device size.
Device start Normally 0 but you can change so that it will start putting buffer start data at some other address.
Device End Should be the end of the device or equal to device size + device start - tells the program where to stop programming at.
Hex file start Most should never touch this - for pasting together hex files. works the same as buffer start. IF you have to ask you shouldn't be using this.
Hex file end Most should never touch this - for pasting together hex files. works the same as buffer start. IF you have to ask you shouldn't be using this.
Hex offset Makes it load hex file data at different place in the buffer
Buffer notes:
The buffer size is always the
same as the chip size -- extra data will wrap around!
To manipulate the data you can do it a few different ways -
you can make use of the buffer or hexfile-start and end
settings which will load the buffer from the start point to the end
point and will ignore the rest. This is useful if
you have a lame compiler that includes the stack as part of the data.
The hexfile offset increases the address of where the file is loaded. To move it down you would need to increase it enough to cause it to wrap around.
Why can't I find my device in the windows program? You must have your video set to at least 800x 600 resolution to see the complete parts list.
How do I put a 1 meg Bin file into two 27C512s (or similar splits)? Assuming a linear split (See below for odd even splits), load the buffer and burn the first chip normally. Then change the start of buffer to 10000h (or what ever the capacity of the chip is) and burn the second chip.
Why am I having problems programming a FLASH part?
APC Sleep mode power down etc. These set ups are a problem - especially on lap tops. They are in the BIOS code so there is no way for us to turn them off in software. They are often the cause of problems programming the Flash 29C256. There is one IBM lap top that is set up so you CANNOT turn it off. Make sure there is a way to disable the power down settings before you buy a lap top.
Software updates? See Upgrades
Software requirementsWin95, 98, 98SE -- Win2000 is hoped to added late 2001
Minimum DOS version required for I-DOS-I-PP1 operation? 3.0 or later
What program should I run? Unless you are using and adapter you should run fileprom.exe dos and for windows run win_prog_.exe
What is new with the 3.60 or more DOS software? It has a fix for EPP and ECP printer ports. It is no longer necessary to change them in the CMOS setup tables.
Why is there also a DOS program? - There are several reasons for us staying with DOS. It is faster, many customers use BAT commands to script procedures using the COMLINE feature, It becomes messy to install device drivers. By sticking with DOS you can make a bootable DOS disk and it will run on any machine with out installation many of customers like that because it enables them to run it on a clients machine with out doing an installation.
Version 1.79 has a device selection bug
Particular chips
27C256R - I can't reprogram this why? - it is a OTP(One Time Programmable) It can't be reprogrammed.
2732 - It was working and then I erased it and now it won't program - all of them from that batch act the same way. - Often these were programmed at the wrong voltage - once erased they will never work again.
How do you put a 28 pin chip in the AIP socket? Leave the empty socket holes on the end with the lever. The end of the chip with pi 1 is near the lever.
What are the steps required to program a chip in the WIN program? Start the program, pick a device from the list that matches your ROMs part number. Press file type if it isn't binary. Press load buffer and pick your ROM image file. Press blank check. Press program.
What are the steps to copy a chip in using the DOS program fileprom?
Why am I having trouble programming a Flash chip? If you are running under M$Windows make sure you have very little else running or try it from DOS. If you are trying to load a Hex file on an Atmel remember that those parts have an automatic erase cycle which will cause problems with Hex segments as they load. Save your object code as a binary file and try again. - see
Why isn't the check-sum the same? Several things can cause this - if this is a hex file the sum-check depends on what was in the buffer before the the data was overlaid in the buffer. You might try filling the buffer with 00s. Also, you may be comparing the file check-sum with the ROM check-sum -- they are not the same thing.
I get an SES error code - This probably means you have a bad check sum due to the un programmed part of the chip. You would normally fill the buffer with FFs or 00s (depending on the particular ECM computer) before loading the file to the buffer. Hex files can also give bad check sums if they over write the same address space.
More about Checksums - There are many types of checksums! The Checksum the pocket programmer does a Byte Checksum while GM does a Word Checksum, because they are using a 16bit CPU. They also store their checksum at the beginning of the Hex file without including it in the actual ROM code. GM might use a Word or Byte? on their chips (if anyone know this for the different computers please email us), but definitely use Word on the OBD Computers.
Well what is a Byte Checksum? This is where all bytes are added together throwing away any 16th bit carries to keep the Sum check one word or 16 bits in length. i.e. 12h + BDh + 56h + C8h = 01EDh In other words, the pocket programmer makes a 16-bit check sum by adding all the 8 bit values in the buffer while throwing away all the carries above the 16 bit boundary.
And what is a Word Checksum? This is were all the 16 bit words are added again throwing away any 16th bit carries to keep the Sum check one word or 16 bits in length. i.e. 12BDh + 56C8h = 6985h
Why can't I find the non CMOS version of this chip in the DOS software? The NMOS version might be listed as the same number as the CMAOS version - 28(C)16 means both 2816 and 28C16.
Where can I find a particular EPROM ? We have a few see Surplus ICs
Why does it fail with Intel parts using the I-874X or I-875X adapter? You need to highlight the Vpp Button and Press the 'T' Key. This will bring up more buttons on the right side of the screen. You need to increase the Program Delay X2 or more when using Intel parts as they are slower than other Manf. These parts need more time for the MCU to send the data back other wise the data address will be offset by 1.
What is the correct programming voltage for 2732s? 2732 - Oh, this is a nasty chip - it comes with more than one suffix and has differing programming voltages. If you program it with too high of a voltage you ruin the chip - AND sometimes blow out the programming voltage supply. The new programmer should be better about this and not cook itself. Be VERY careful about WHICH 2732 you are working with. Look at the suffix to the part number As use 21V Bs and Cs use 12.5 anything else use the plain 2732 setting.
What is this secret 'T' function (88 in DOS) all about? First, It is not listed because 99% of the time you don't need to use it. Select the vPP (programming voltage button) and type the letter "T". This will bring up a hidden menu.
Why am I having problems programming with the PLCC adapter? If you are programming 32 pin layout parts (like most FLASH) you need to remove the bottom header from the adapter. It is used for 28 pin layout memories (512 or smaller)
Emulator problems? there was a version change for the newer board the old software wont work with the new board and visa-versa.
What Can I do to keep from breaking the pins on my Emulator cable header?
Put a Machine socket on the Emulator header. You end up plugging the pins of the machine socket into the car's computer socket instead of the cable header. Now, if you break a pin off, it will be the machine socket and not the header. Then all you have to do is replace the socket. We should have some in stock for you. Not a bad Idea to use a machine socket on your car computer board as well.
How do you use a 29C256 in place of a 27C128 or 27C64? - you will need to 'relocate' the ROM image to the top of the 29C256 address space.Do you support SNAP or other programming algorithms?
The SNAP algorithm is only one of several that works; its
advantage is one of speed. When programming UVEPROMS one must keep
pulsing the cells until they are programmed and then add programming
time to insure that they are programmed enough
that they won't flip under different temp, Vcc conditions. By
increasing Vcc it helps provide a worst case condition.
Other parts of the algorithm count the number of pulses to flip the bit
and then multiply that by some factor and add
insurance pulses. There are all numbers of recipes for doing this. Some
expose the chip to excessively high Vcc that
can effect the life time of the part. Some are quite slow.
The pocket programmer uses the quick intelligent algorithm
(often just called quick) with an elevated Vcc which is
supported by all the manufactures (ask you sales rep to get you in
touch with a factory engineer if you doubt me). It
is a somewhat more conservative system that stresses the chips less (as
is required by some military specifications)
and uses a bit more time in programming.
The snap algorithm is for programming chips in consumer
products in
a minimum time (cost), but at the expense of more stress to the
part.
It is possible (but not recommended) to program
without raising the Vcc and using a very high number of insurance
pulses, but with the larger chip sizes that takes a very very long time
and fails to provide a worst case check that
the elevated Vcc provides.
How long should I erase a UV erasable chip (27xx types?)
Take a programmed part - put it in the eraser for a minute at a time checking each time to see if it is erased. once it is erased triple the time for all chips of that particular part number AND manufacturer. See theD_erase
My eraser rattles is the bulb broken?
No. it is normal to make a slight sound.
My eraser won't light up?
Most likely because the door is open. There is a tiny safety interlock that keeps it off unless the door is closed. You can check the operation by looking at the pilot lamp - it is actually a bit of florescent material that glows from the UV light.
I programmed my part with a HEX file - If you don't have the unit set to hex - it will program the part with the ASCII representation of hex instead of the binary You need to set the software to the correct file type.I don't seem to be able to find a supported chip on the windows program? Be sure your computer video card is set for at least 800x600
I am working with S-Record files do you have any utilities? Download the Srecord utilities that convert Srecords to Bin and Bin to Srecords. To contact the author of these utilities, Mr. Ant Goffart, Email him at ant@goffart.co.uk Please thank him for giving permission to share his software.
I need to convert a Hex file to Bin so I can program a particular flash part? Use this Hex2Bin converter. HEX is incompatible with FLASH memory. The empty part of the file is best set to all FFs or 00s if there is a sum check involved

Where is the BIN editor for doing EFI computers?
There seems to be some confusion as to what a bin
editor is (it might
mean something else in the EFI world than in
the electronics world?) The programmer comes with a Bin or Hex editor
where you can change values of different addresses, but there are no
boxes saying this location will set the idle etc.
Also, the programmer does not include instructions on how to
tune up a car ROM. All the programmer will do is put the
information in the chip you provide that information from someone
else's program.
