Hi! Good news! I ordered a batch of the N8 PCBs. The N8 is a group project design from the N8VEM home brew computing project. I received some questions about the N8 so I am sending this bit of background on the project. The N8 project is on the N8VEM wiki and mailing list. I had previously offered the PCBs there and here on VCF directly to builders. However now I am also putting them up on VCGM to help get the word out a little better. The N8 is intended to be a "home brew" style computer in the style of early 1980's all-in-one home computers with a usable set of features such as color graphics, audio, an assortment of mass storage options, a variety of ports, etc. Although a bus expansion is supported no additional boards are required. The N8 is designed so builders can assemble it themselves using common tools such as basic soldering iron, VOM, etc. It is a simple two-layer board construction using all commonly available plated-through-hole (DIP and PLCC) components without requiring any SMT skills, programmable logic devices, etc. A quick summary of the N8 features: Processor & memory: Z8S180 CPU (Z80 compatible, 33MHz max), with 1MB SRAM and 512K Flash boot ROM (in-circuit reprogrammable) Primary Interface: Color video (TMS9918A), Sound generator (AY-3-8910), and PS/2 keyboard and mouse ports Mass storage: IDE drives (including CF adapter) port, Floppy drives port (1.44MB 3.5"), and SD socket Expansion I/O: Two Serial ports, Parallel Printer port, Two MSX compatible Joystick ports, RTC w/NVRAM (configuration data), RS-485 networking port Various diagnostic LEDs, "front panel" status indicators, buttons, with optional debugging hex display and keyboard (DSKY) A builder has also designed an enclosure for the N8 http://n8vem-sbc.pbworks.com/w/file/52623834/N8%20Case%20Construction.zip Photos of prototype enclosure http://groups.google.com/group/n8vem/browse_thread/thread/e7cf446f1e33760c# There is an MSX BIOS ROM image (in development) here http://groups.google.com/group/n8vem/browse_thread/thread/c880ea6aa13ccff7 There is a Z-System ROM image (in development) here http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder?m=RomWBW The PCBs should be here in mid to late Jun 2012. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder?m=N8-final Click to view PLOTS of PCB https://www.freedfm.com/freedfm/0011697403232210/results/plots.htm The N8 PCBs will be the usual $20 per PCB with $2 shipping in the US and $5 elsewhere. I am offering the PCB only. No assembled units as this is for home brew computers. Most of the chips are available through Jameco, Digikey, etc. Some of the specialty chips like the AY-3-8910 and TMS9918 would have to come from eBay, UTSOURCE, Unicorn Electronics, etc unless you have those on hand. I don't know what the final assembly cost would be and it would depend a lot on how you build it. Styles differ dramatically and depending on your supply of parts could vary widely. Several builders have working units on the N8VEM mailing list so I suppose you could ask them or look up costs on the parts list/BOM from the wiki. Since it is an all-in-one design rather than multiple boards there are a *lot* of parts stuffed into the 60 square inches of PCB. However there is only one PCB. There is some efficiency gained by stuffing everything into a single board rather than spreading out over several boards on an ECB backplane. The N8 is a bit like the P112 SBC except it is all DIP/PLCC (PTH PCB assembly, no required SMT) and has richer IO options like video and sound. It is larger though so it is a bit of a trade-off. Thanks and have a nice day! Andrew Lynch PS if you want to see detailed close up photos of the N8 prototype in its enclosure then download the large ZIP file above on the N8 Case Construction.
