[EI 502, IC 503, EI 405, EI 611] My Microprocessor Design Book is finally Ready!

My last blog post was about a series of questions. If you, seriously, wanted to solve those problems you could do well by reading this text I had published quite a while back. I finally have a electronic version that can be shared easily. Send me  a mail at ddas15847@gmail.com  and I will share it with you. I need to update the book a bit and orient it with the WBUT syllabus. This version, as is, has a lot of solved problems and a lot of exercises too. If you would like a copy of the Electronic version, I'll give you a discount of the price on the forthcoming revised version.(It's free for my current EI 502 students, of course!) The current Electronic version will cost you Rs.150 and when the revised version comes out you would be able to buy that at list price minus Rs.150. If you are paying in USD it is $3.99.
