Just a reminder -- the money collection phase of the group buy ends at the end of the month. On Tuesday, I plan to place the board and component orders based on whatever I've received by then. We have 42 paid units for the group buy so far, an excellent response! There are still three folks who expressed interest, but have not paid. If you want one of these, now is the time! Here are the details again, in case you need them: The 32K RAM kit is for an Omnibus card that should work in the PDP-8/e, 8/f, 8/m, and 8/a: - Complete kit, including battery, PCB and parts. Soldering required. Includes IC sockets for the RAM kit, but not for the prototype area. - The amount is $95, including shipping. If you are outside the USA, please add $20 for shipping. - Please make Paypal payment to this email address. It will show my wife's name, Hildebrand. (My initials are vrs, and that email is just my initials at msn.com.) - Ordering for this project will close March 31, 2014. - The kits are expected to ship by May 8th. (Long PCB turn time is used to keep the price down.) - Please allow up to 10-days for delivery. Some features of the kit: - Battery backup with long life. - Inhibit on power fail to prevent memory corruption. - Easy to build, with all through-hole parts. - Provides full 32K memory in a single card slot. - Cooperation with any mix of core memory or ROM boards. - Compatibility with the Omnibus. - Most of the full Omnibus board area is laid out for prototyping. - High quality board with gold fingers, plated holes, silk screen and solder-mask. You can read Steve's article about the prototype here: http://www.tronola.com/html/ram_for_pdp-8e.html Thanks, Vince PS I tried to send this yesterday, but it seems to have never arrived. Apologies if that version (or this one) appears after the end of the month.
