There have been clones of the Behr-Bonz multicart produced in the past and they have a couple of technical issues.
Since some people have associated these clones and their problems with my products, I find it necessary to post images of genuine Behr-Bonz carts from the 2015-2017 production batches and from those of 2008.
Clones of the Behr-Bonz have a red PCB, no proper screw holes for the case and use HASL on the edge connector.
The HASL connector is badly worn after only a few insertions on this unauthorized clone.
I feel I must correct you on a couple of points here.
The red PCBs were made by me, in a limited run of 10* (see below) boards. They are not unauthorized, they were made after a serious of email exchanges between myself and yourself (I still have the emails in my inbox, the first reply of yours is dated 1st September 2009 - As you can see from the PCB photo, the boards were sent off for manufacture in October 2009, shortly after the email exchange).
As agreed, they carry the mark of "By Eslapion & Viande" and the original, unmodified ROM. You explicitly asked that no credits be changed, as I was only too happy to comply - I would not wish to take credit for someone else's design.
They were sold (at cost) at an open day event of the Retro Computer Museum shortly after being completed. I can forward you our email chain if you want further details.
The reasons for the missing holes and HASL edge connector (which imply are indicators of poor quality) are easy to explain. I did not (and still do not) have an actual VIC-20 cartridge. 3D Printers at the time were still a novelty, and getting accurate dimensions for where the hole went was something of a difficulty. Since I was not able to supply a case, and everyone was almost guaranteed to be running it "bare" anyway, I didn't put any effort into putting a hole in. I left space in the PCB for a hole to be drilled (you can see this space between the two resistors at the top, immediately to the left of the 74LS273 chip above the EPROM).
The HASL plating is far simpler to explain (beyond the fact that most of the people who acquired these boards were going to leave them inserted most of the time anyway) - the gold plating option was more expensive. And in 2009, I was on a damn tight budget.
As for technical issues... to date, there have been 11 boards made. 10 that were sold on as agreed, and 1 I built (from leftover parts) and kept for myself. To my knowledge, there has never been a single issue with any of the boards.
While I appreciate there probably are clone boards out there that you have *not* authorized, that have many technical issues, the red one picture above in this thread (Marked "BUILT OCT 2009" and "BY ESLAPION & VIANDE") are not among them.
