| 20,00 Euro | A complete and assembled TL866 Eprom Adapter, including a 48 pin ZIF Socket. (Also for TL866II - TL866II Plus) |
| 15,00 Euro | Like the above, but then as a complete DIY Kit. |
This TL866 Eprom Adapter supports Eproms of the following type : 27C322 (4Mx8-bit), 27C160 (2Mx8-bit), 27C800 (1Mx8-bit) 27C400 (512kx8-bit).
Converts the mask- EP- EEP- ROM pinouts of the above parts to the JEDEC pinout of 27C4096 EPROMs (as supported by TL866 USB programmer, and possibly other cheap programmers too).
The TL866 programmer is supported through its MiniPro software by selecting '27C4096' device and disabling 'Check ID'. You may also like to reduce VPP Voltage to 12.50V (check your device data sheet).
TL866 Eprom Adapter with support for 27C400 / C800 / C160 / C322 Eproms
Since the TL866 has only a 40-pin programming socket, the extra address pins on 27C800 27C160 are configured manually on the Eprom Adapter via dip switches: (Rotary settings below, for dipswitch settings see picture.)
27C400 : no need to set dip switch, program all 512kB in one pass.
27C800 : program in 2 512kB passes: Rotary set to 0 (bank 1), then Rotary set to 1 (bank 2)
27C160 : program in 4 512kB passes: Rotary set 4 times to 0,1,2,3 (banks 1,2,3,4)
27C322 : program in 8 512kB passes: Rotary set 8 times to 0,1,2,3,4,5,6,7 (banks 1,2,3,4,5,6,7,8)
Since 27C322 is a slightly different pin-out to the other devices, there are 2 jumpers that need to be set accordingly to support 27C322 devices. (only when programming the C322 Eproms)
