Hi
With the reissue of the CEM3340 I thought it would be nice to add a couple of the VCDCOs to my ever expanding modular I have 2 2716 eproms winging their way to me but I need some helpful soul to let me know where or how I can get them blown with the files I have.
I don't really want to buy a programmer as I only want 2 in my system
Any ideas?

I did something similar, but wit a FIFO (9 bits wide, 256 words) so I can refill the memory (the FIFO) with waveforms "on the fly"-ish Rolling Eyes
