Dick, I have a couple of "dead" E1938A's. Your more than welcome to a 'pulled' U105 if that's any help. Postage to the States would be reasonable. Kit VK2LL Sydney *********** The E1938A I have has an empty socket for U105. Does anyone know what it was used for ? It is a 16C74 8 Bit uController. 73, Dick, W1KSZ
