Peripheral Technology

 Welcome to Peripheral Technology's retro computer site.  Most of the products in this site were produced by Peripheral Technology from  1978 through the late 90's. With all the recent interest in retro computing I have made these products available again. Some of our products are not available due to lack of bare boards;  these products will still have a product page for historical reference.  Peripheral Technology was founded in 1977 while I was in college.  My first product was the FD-1 floppy disk controller for the SWTPC 6800 computer.  From there I launched many 6809, 68008, 68000 and finally 68020 based computer boards.  There are limited amounts of these products available. The quantity is determined by the remaining number of bare boards, and to some extent, the availability of  components that have not been made in over 30 years.   In a few cases we may have more boards made of some of our popular products. In most cases,  assembled board orders will be built after they are ordered.  While a few boards are in stock, turn around time will typically be around two to three weeks from receipt of order for boards not in stock.

To order product, send a list of what you wish to purchase and the ship to address to, I will email you ordering information and shipping cost.  I am retired now and not always around but I generally respond to email within a couple of days.
