Shop : T48 Eprom Adapter voor 27C400 / C800 / C160 / C322 Eproms

De T48 Eprom Adapter ondersteunt Eproms van het volgende 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 T48 USB programmer, and possibly other cheap programmers too).

The T48 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).

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:

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)

Dit ontwerp is gebaseerd op het werk van Keir Fraser, helaas past de TL866 versie niet op de T48 programmer
