Today I assemblied the new 27C4096->27C322/160/800/400 eprom adapter (v4 ) for the tl866(II) from Keir Fraser..
With this adapter you can program 27c322, 27C160, 27C800 and 27C400 eproms. The new adaptor comes with a nice rotory switch to select the bank.
27C400 eproms are not affected by the rotorty switch, and can be programmed by default.
Keir is selling these DIY kits.. You can find him on facebook or via GitHub.
