Default Tesla Programmer

Last year I started looking at the problem of programming Tesla PROMs and seeing if I could use the existing Acorn PROM Programmer (intended for National Semiconductor PROMs).

Well it turned out not as the programming method is effectively reversed, data lines are pulled low rather than high. It proved difficult to adapt the design to cope with both makes of PROM due to a lack of spare control lines. The easy solution was to build a second programmer card. After a 6 months delay (caused by other project diversions !) I've finally gotten around to finishing it off. I've updated my PROMER2 software to PROMER3 which works with either or both Programmers.

I've put a full description and write up here including the source code: http://www.theoddys.com/acorn/replic...mer_board.html
