Hi I've updated the N8VEM wiki PCB inventory list to correct several inaccuracies and correct quantities available. There are many PCBs remaining so if you are looking for some please contact me. Especially there are some recent PCBs for the ECB like the DSKY, Color VDU, MF/PIC, and DiskIO V3 which may be of interest to you. There are technical data for these PCBs on the N8VEM wiki including schematics, PCB layout, KiCAD EDA files, software, photos, etc. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=Board%20In… tion Using the N8VEM mini SBC V8 and/or the ECB backplane PCBs is sufficient to build your own system. There are sufficient 6x0x PCBs to build 6502, 6809, or 6802 CPU based computers. There are some mini-boards like AT2XTKBD for $5 each that allow connecting AT/PS/2 keyboards to PC/XT computers. Also there are ECB to Z80 socket adapters which allow the ECB boards to be connected to a Z80 socketed CPU rather than an ECB bus. Here is the link for your review: http://n8vem-sbc.pbworks.com/w/page/35044530/PCB%20Inventory The PCBs are $20 each plus $3 shipping in the US and $6 elsewhere. If you are considering getting one or more now is the time! I am stuck and need to move the remaining boards to free up the funds to do other board orders/reorders. I appreciate all the community support for the N8VEM home brew computing project. Thanks and have a nice day! Andrew Lynch PS, there is also one S-100 8088 CPU board PCB remaining.
