I'm sorry Jim, but I can't answer your last question. However, I do appreciate the extra information you have provided. The information I have received to date has met my requirements. Thank you very much for the offer of additional project sheets. Once again - Thank You.

As a student (several decades ago) I developed several 64K and 512K DRAM cameras. I used TI and Intel DRAMs (at the time I was unaware of the Micron opticRAM). In its day, I thought this was pretty cool. The DRAM was attached via tether to my computer and I varied the refresh rate to get gray scale. Assembly language is a beautiful thing (or a nightmare). Of course the real trick was to remove the ceramic package lid and polyimide protective "goop" to reveal the chip die imaging surface (without damaging the die). Anyway, I have attached the covers of Mircro IS32 and IS256 information that I readily found. I believe I may still have the MicronEye Camera and Manual, as well as other information. If you would like copies of this information let me know. I will be out of town for a week or so (and I will have to recall where I have stuff the other information). Why are you interested in the OpticRam? Enjoy, Jim
