Interest in a PDP-8/e/a/f/m 32K RAM kit?

On the question of whether F-RAM would be a suitable replacement for the CY62256 CMOS/battery solution: There was a longevity calculation posted that appears to have been in error. The 1e14 cycle limit was said to be good for 30-years continuous access at a 1us cycle rate. I calculate about 3-years. Perhaps 2us would be a more appropriate cycle rate for the PDP-8 and that would make it 6-years. That might be considered sufficient and I have added a section discussing the availability of various F-RAMs to the article: http://tronola.com/html/ram_for_pdp-8e.html#F-RAM Unfortunately, the suitable through-hole devices are now obsolete but are still available from Hong Kong/China. I would appreciate any comments you might have. By the way, in response to comments here about how the Omnibus interface compatibility issue was handled, I have rewritten parts of that section. I hope it meets critical approval now. I would like to say thanks for holding my feet to fire. I think it has improved the article. Steve Lafferty
