Jan 8, 2016 at 6:13	comment	added	tcrosley		@TonyRobinson I did try to address the memory isuse (as you acknowledged) but I was also trying to provide information re your desire to make a computer out of discrete transistors and/or relays, and to illustrate that several have been successful at this. Good luck in your endeavors.
Jan 8, 2016 at 4:17	comment	added	Tony Robinson		ctd... this is closer than I'd guestimated, but you do need the address decoding and I'd put in more transistors per memory cell. Maybe a one transistor one capacitor 'DRAM' memory cell is also possible within budget.
Jan 8, 2016 at 4:07	comment	added	Tony Robinson		Sorry, the "I have researched this over many years" was buried in the second paragraph. I've edited the title of the post to clearly state it's the memory I care about.If you can get by with 1K bits, you could build one with transistorized flip-flops; 2048 2N3904's will cost 3¢ apiece ($60 altogether, plus the other components which will be even cheaper -- resisters for 1/2 a cent etc). You can get PCB's made for $10 apiece, then hire a kid to stuff them.
