27C400, 27C800, 27C160 PROGRAMMING ADAPTER (as 27C4096)

Hello,

This is a tested and working circuit.

With this adapter you can read and program 27C400, 27C800, 27C160 with your 27C4096 programmer.

With this adapter you can read your AMIGA KICKSTART ROMs and back them up for yourself in case of any failure.

Select 27C4096, then select the voltage and Puls delay values ​​suitable for the EPROM (27C400, 27C800, 27C160) from your programmer software.

In your programmer software, leave the "Check ID" box blank (do not check).

To program 27C400, leave Pin-1 and Pin-48 of ZIF socket empty. (As in the pictures)

You can program 27C800 EPROMs in two steps using switch A18, first one half and then the other half.

You can program 27C160 EPROMs in 4 steps using switches A18 and A19.

Component List:

48 PIN ZIF Socket Manufacturer Product Number 248-1282-00-0602J

2 pcs. 20 pin 2.54 pitch Male Pin header

2 pcs. 3pin 2.54mm SPDT slide SWITCH
