OPTION 1 -- BEST CHOICE -- ORDER DIRECTLY FROM PCB MANUFACTURER
The SBC-85 Hardware is a publicly shared project, i.e., the files to build the hardware are free for all to use for non-commercial purposes. These files can be downloaded in the documentation page for each piece of hardware. The files required for building can simply be uploaded to board houses such as JLCPCB and getting a set of boards really is as easy as clicking the quote now button, uploading the zip file, adding to cart, and checking out. There are numerous videos and guides on youtube on how to order from the various PCB shops. Note that some of the SBC-85 boards use two traces between pads which tightens the board specifications (i.e., minimum spaces). As far as I know, all the board houses except JLCPCB charge extra for narrow widths and spaces while JLCPCB has the same rate for gaps down to 5 mil. In the end, rather than paying for domestic shipping and certainly before paying international shipping, it is cheaper and probably faster to order directly from the PCB house. After receiving your boards, consider jumping directly down to Option #2 (below) and SHARING the extras.
OPTION 2 -- JOIN A LOCAL VINTAGE COMPUTER GROUP OR HACKERSPACE AND SHARE AT COST
The boards were designed at the 100mm x 100mm whenever possible because that is the size for the cheapo runs from board houses such as JLCPCB. For new accounts which get a $5 coupon on shipping and boards costing 5 for $2, the delivered cost for 10 boards is a few dollars per board. At this cost, consider simply sharing the boards with other 8085 enthusiasts at cost or swap for something. Unfortunately, this offer often goes away for repeat customers so it is quite likely you can get boards from the manufacturer cheaper than we can. So look up your local vintage computer user's group, local hackerspace, or forums to see who locally is interested in sharing boards. After all, this is about the technology, not creating revenue for the postal or shipping services. If you are interested in sharing boards, please let me know and we will keep you on our list.
OPTION 3 -- BUY FROM ME OR SOMEONE ELSE THAT HAS ALREADY HAD BOARDS BUILT
Probably the cheapest way to get boards is to send me an email and buy them directly from me using paypal. No seller overhead from tindie or ebay--- the process is simple, quick, safe, direct. . . But hardware is also available through the regular sources like ebay and tindie or user groups such as the site Retrobrewcomputers.org has a hardware inventory list and contact information of those selling the hardware. Typically, these are enthusiasts that have ordered boards and are selling excess. There are listings for SBC-85 hardware on ebay directly from me and, at times, from others that have had PCBs built. The pre-shipping cost of bare boards can be a few dollars for 100mm x 100mm boards and will go up with additional features such as hard-gold plated fingers, larger boards, kits, and assemblies. There is an appreciable jump in cost between 100mm x 100mm and anything larger, with 125mm x 150mm boards boards being a couple of dollars more than 100mm x 100mm. Note that the cost of the board to whomever is selling the boards can vary significantly by which board house they use. For the same layout, delivered cost for 5 pieces of 100mm x 100mm board can be as low as $5 to or over $100. So if the seller you find has boards that seem much more expensive than a several dollars, that may in fact be their actual cost. But it does not hurt to ask a few questions to make sure someone is not taking advantage of a (technically) free board design.
