NEW Arm Wrestling Repro BAK PCB

Might be hard to get a loaner as this might hurt the value. Sadly.

I asked the only person i know with a board and he said no. Theres a couple members here from California that have boards. Idk where in ca you are.

I did meet a local last month buying a game who had an arm wrestling in the corner wrapped up. Said he never plays it but wouldnt sell. Still holding out hope for that one.
 
Well, I hope there is at least one person out here on the interwebz with a board that would like to see these be reproduced and available for others to enjoy, but honestly it isnt manditory I have one to make this board. Schematic should get me there. We will see.

Good to hear.
 
Editing my post as I have made a decision. Got schematic in hand and bill of materials in hand. The board is going to have the 4 proper connectors to interface with the video and cpu cards, sockets for the 11 proms, but instead of all the individual ic's it will have a single CPLD. So this wont be an absolute identical as original card but it will be much cheaper and faster to make. I'll keep everybody updated as things progress.

Someone should repro the rubber damper piece that goes between the base and restrictor. :eek:

Seems to be the only htf part aside from the security board.

That is cool ! You will definitely speed up the development using a CPLD. I still want to have an exact repro of the original board but I will need to find one at some point. As mentioned earlier, I doubt that someone who has one will be willing to loan his PCB and on top of that, there are a couple of people looking for one.

Awesome news!

Or atleast a good picture of it. Ive only seen pics of it still on the joystick and you cant see much. Im sure most of them need replacing at this point, likely broken down by now.

sign me the frick up I'm all in cost be damned, if you need investment let me know...

Looks like Mike's has manual pictures. So I guess the manual had a decent pic.

I mean you could probably just cut a thin piece of rubber mat. Use a hole punch from Northern Tool for the screw holes. The center hole may have been oblong, but a round hole would probably suffice.

If not, I sometimes have to cut custom gaskets. To do so I take a piece of stainless tubing or pipe, sharpen the tip edge, and drive it through with a hammer. Leaves a nice, clean hole. I'd think it would be easy to just bang the tip oblong and use the same method.

The sizing should be easy to approximate using a restrictor plate for a template.
 
The phases to complete this board are:
Original Netlist Capture
Creation of HDL Blocks
Simulation & Testing of HDL Blocks
Instantiation of HDL Blocks / CPLD Selection
New Netlist Creation
Board Layout
PCB Creation
Board Assembly

Currently I am still capturing the original netlist. I work on it during my lunch break when I can. I'm also doing a leaderboard overhaul on the Global VR PGA community server at the same time. So things will accelerate after I complete that. But all parts have been captured, datasheets pulled, pins and descriptions documented, and nets being connected. There are over 1200 pins on the original board that must be defined/connected by hand via reading original hand drawn schematic. Takes a bit haha.

This board is going to happen, it just takes time, and needs to be fun not stress/work. I'll check in more.

any updates on this project?

Thanks for the update, can't wait
 
I was debating on picking up a punch out pcb and converting it.
Sorry I wasn't specific before, so based off of a punch out pcb what would I need to do to convert it to an arm wrestling?

If it's the same as SPO: this board, a working PO/SPO/AW board, EPROM set for AW, PROM set for AW.

This board (the security board), AW ROMset (EPROMs), AW PROM set. Not sure offhand if you need an extra wire for the pull feature on the joystick.

A control panel with a 5-way joystick that has been restricted to 2-way and has the rubber grommet to cushion the rapid left/right action would probably make it nicer, but a SPO control panel or a PO control panel with a 5-way stick installed would work.

I learned that the video and bak boards must be of the same revision. I.E. 1 or 2. Due to the EEPROMs used on the video board the design is different between the two revs and if you mix a rev 1 bak with a rev 2 video board you get graphics issues. All of this has been documented by the user 2600. I just learned the hard way.

I have only seen rev 1 AW sets. With that said the EEPROMs and PROMS for AW are going to be for rev 1 hardware. So the best thing for me to do is build a single board that replaces the video and bak board. That means you will only need a PO, SPO, or AW CPU board.

I have acquired a loaner AW boardset from a collector and swapped my PO CPU on the AW boardset and verified both boardsets still work properly.

An honest time frame is 9 to 12 months. I have a bunch of projects in front of this, family, work, etc. This isn't the only thing I do and I do it in spare time for fun. Its going to happen, but I want to be explicitly clear on time frame expectations.

Sounds great, subscribed and rep'd!
