and I had interpreted to make these measurements with only JP3 ON, that's all Voltage jumper Jp3 ON and Jp5 ON. Measurements with installed adapter and chip on it. You activate Vcc at first, then activate from SW all adress signal one by one on /off. The best one check adress/maeasure voltage direc...

i select Jumper JP3 and JP5 ON, measure A18 = 3,56 Volt was really JP5 set in chip programming ? yes The read-write operations on the chip have always been done with jumpers JP2 and JP5 ON in your previous post suggested these measures Connect adapter with chip . Programmer voltage jumper Jp3. Will...

A18 = 0 Volt (BU3/21) Check jumper Jp4/Jp5. It should be Jp5 (top) i select Jumper JP3 and JP5 ON, measure A18 = 3,56 Volt question, I tried to follow the pattern of the adapter TSOP56B1 and known differences between the pins of the chip (address) and the corresponding pin of the bus BU5. For examp...

Connect adapter with chip . Programmer voltage jumper Jp3. Willem SW 0.98d12c3, Test H/W. Activate 32-Vcc. Keep activ for all next measures. Activate 12-A0 on/off and measure on top adapter bus pin 32 +3.5/0V Next for all adress pins one by one up to A19 and confirm +3.5/0 A18 = 0 Volt (BU3/21) Are...

Ezo писал(а):Check adress lines A0...A15 from adapter system connector up to target chip pins.

controlled with magnifier and testers and it is all ok

74ACT04 replaced with 74HC04

WITH 0.98D8 and 98D12C3

SW select 16bit 28F160B3B
- check ID OK
- erase OK
- blank check OK
- write quickly and seems ok though
-verify Error
-read from the chip OK but not identical to writing

regards Drago

no JP1, JP2, JP3 and the voltage drops, sometimes under 2.7 volts, and the program gives me error as Vpp Range Error http://img254.imageshack.us/img254/477/vpprangeerror.th.png In fact, I measure on pin 9-15-43 (2.71 volts), this value is the limit for which I sometimes get error, I think Jumper JP2...

I went over all the solder on the pins of the socket adapter clean flux and I got the correct ID http://img842.imageshack.us/img842/6298/idok.th.png then apply the procedure to your nominated: use sw 98D12C3, ezo4v4 jumpers -Jp2 (+3.6), Jp5 SW select 16bit 28F320J3 - check ID (0x0089 Intel, 0x0016 2...

for all, the sw is 98D12C3 Adapter DIP 32A jumper 1,3,5 chip ASD AE29F2008 ID OK, READ/WRITE OK http://img46.imageshack.us/img46/9081/ae29f2008.th.png Adapter DIP 32C jumper 1,3,4 chip P28F001 ID OK, READ/WRITE OK Adapter PLCC 32A jumper 2,5 chip SST 39VF020 ID OK, READ/WRITE OK http://img16.imagesh...

Hello
Ezo not abandon me

More details ? Have you tried erase , write (selected 16bit 28F160B3B) ? select 28F160B3B I tried deleting the first block of 16 Mb and then immediately perform blank test, the program tells me that the chip is not empty, I try to write the same block of 16 Mb but it never starts to write, then int...

Hello ..... Ezo I replaced the 74HC04 added for modify hardware and software 98d12c3 gave me incorrect ID on the chip mentioned above. I connected pin 14 of the 74HC04, directly to the output of the 7805 and pin 7 to GND it gives me the correct ID with SW 98d12c3 I tried to read and verify all the c...

0.98D12C3 (Test)- Test Hardware (my measurements in red and blue) http://img594.imageshack.us/img594/5690/immagine17m.th.png Test Adapter tsop56b1, compared with the table below, list only the changes from the table anyway here are the changes that reflected http://img577.imageshack.us/img577/6929/...

Are you getting valid ID, SW 0.98d12c3, selected 16bit 28F160B3B ? Before you reported valid ID. What settings applied - modified hw, sw, selected device ? 0.97d12c3 is not compatible with modified hardware, don't use it. My answer to both questions sorry if embedded with the software, but I see it...

replaced the 74HC04 and Hardware present, all ok TEST chip SST 39VF020 Jumper 1, 3, 5 (and then also tried, jumper 2, 5 as in chip-test file) SW 0.98D8, selected device SST29VF020, ID, reading and verification is OK SW 0.97D12C3 and 0.98D12C3, selected device SST29LF/VF020 and I get bad electronics ...
