Programmers Wooo! - BK Precision 866b (aka Elnec Beeprog+) Universal Device Programmer

[@games2replay]

Nice work, I wonder if you saw my post on my blogspot about upgrading the psu on my Beeprog+. I ended up using a 15v 4A laptop power supply, anyway I own the Beeprog2 and Beeprog+ but much prefer the + even though it's an older unit. I like that it uses an external psu and doesn't require over priced adapaters for non dip stuff.

I think I found your blog believe it is for the 866 aka beeprog not 866b aka beeprog+ I show here. Either way, it is useful !

Wow, it looks like new. Nice score. How do you find them? By now even Arcade Jason doesn't have as many programmers as you do ;).

[@jacklick]

I typically find them on ebay but have scored some off of facebook too. If they aren't keepers, I offer them up on KLOV. No need for more than a couple :)

@@jacklick This one looks to be a keeper ;). How much do these go for?

[@jacklick]

@@Omega_Mark they don't come up often enough for me to say but I paid 250 for this one.

@@jacklick Ok, thanks. Yeah, they were crazy expensive with more than $1000.

The BK 866b reads, writes, Tests and verifies JEDEC Files? You mentioned that is does CheckSUMs the JEDEC Files. JEDEC files are only used for GAL chips, not for PAL chips?

[@jacklick]

@@waynegram8907 that isn't quite what I said but my point was the contents of a jedec file is variable so you can't just rely on a simple hash of the data for comparison reasons like rom ident does

[@waynegram8907]

@@jacklick When the BK866B READS the Jedec File, what do you compare the Jedec file against to verify if the data comparison matches? In the video you Read the Jedec file but after reading the data how do you test it, you just only did a CheckSum the Jedec File?

@@jacklick Arcade games use ROM chips to store the game code data files but are these considered jedec files or what type of data files are they called on the ROM chips?

[@jacklick]

@@waynegram8907 you can use google or chatgpt. ROM file format is binary

[@waynegram8907]

@jacklick the jedec files are binary?
