oh boy. So that's the beast! Much bigger than I thought. So it's run by a Zilog Z80 CPU. it is essentially a full running computer w/ I/O and peripherals. The block diagram from Hoss indicates that it is connected to the CPU and via one of the Serial Comms connections.
Not sure how to really offer much but I am still wondering about the old board -vs- new board. Are your pics (the two) of the same board, or the old and new side-by-side? I know you said 'identical'.... Here's what I'm thinking; On the larger board you can see the other smaller IC's w/ tie-wraps and white stickers. Those are some type of programmable items as well.. you might need to move those from OLD Bd. to NEW Bd. w/ the old board PROM. (back to why the new board does not know how to talk to your CPU.... )

I think I got it!
Copying the old am27c256r eprom and programming it to the at27c256r did it!
Now its error out on 134 Tool clamp fault.
The tool clamp has been sticky since i've been putting tools in it, ill try to work it and see if I can get it to work properly.

Bought a hoist and setup a bridge to allow me to move the tool changer over and down. the garage door is 96in tall, the machine is about 111, but if I take the tool changer, hydraulic piston, y axis motor and some sheet metal panels I can get it in.

Well I bought my first house, it has a 10ft tall garage with and 8ft tall door, I was able to strip the machine down to just under 8ft allowing the riggers to slip it under the door. I was hoping to get 3 phase, but ive settled for a 400 amp panel upgrade and a 60hp american rotary adx phase converter just for the cnc. I had to remove the y axis motor, the entire tool changer and the sheet metal that attached to the column and saddle to get the height down. I guess it will be a good opportunity to get in and service certain things like belts and hoses. getting the phase converter motor up onto the mount on top of the machine was fun... I used a few pulleys, a pallet rack ratchet straps and an overhead winch to hoist it onto the existing mount. I used the same winch to lift and then lower the tool changer.
The x and z axis screws look and feel great, but the y axis definitely needs to be repaired or replaced. Haas lists a replacement screw for $3000. I can afford it, but id prefer to find a less expensive solution. Ive read about having screws reground or reballed, and this seems like an option, however I dont know the full extend of the damage to the screw.
Once I get the machine back together, other than repairing what's broken the next plan for the HS-1 is to find a suitable HRT310 wiring and drive to setup on one of the pallets so I can spline axles and do 5 axis work. From what I can tell, from the factory only the 5ax models came with the additional 5th axis. and they had no pallet changer. That being said ive seen pictures of several machines with dual palleted 5th axis and drives for each rotary, so I know it should be possible, unless they had a newer control.

@Hoss710 any input on how I should hook up a rotary phase converter to the HAAS? From what I read in the manual for the phase converter, two of the legs pass through, and the third leg is "manufactured". They recommend checking the electrical diagram of the machine and using the passthrough legs to power any circuits that have microcontrollers. From what I can tell in the haas manual, mostly everything is powered through a power supply that uses all 3 phases. The crt, operator pendant and tc door run on legs 2 and 3 of the 115v 3 phase, the work light assembly runs on legs 1 and 3 of the 115v 3 phase, and the standard coolant pump runs on what appears to be legs 1 and 2 from the (I cant really tell). I cant really tell if the power supply that runs the main cnc control runs off of single phase, but it doesnt appear to. so in that case I think I would be ok in connecting the 3 phase input any way I want so long as its sequenced properly for the through spindle coolant pump.

On your Y-axis ballscrew, be sure to check all the plastic oil lines for cracking, and all sections for proper flow. The recommended lube oil, Mobil Vacta-2 can start "gumming" or leaving deposits that can block lines or flow metering parts.
If you're doing all this work I'd replace all the plastic lines and be sure to flush everything else.
Can't help on the RPC, and Hoss710 hasn't been active since January of this year (TTBOMK). Someone else might comment, or make a new post specifically asking for RPC help.

I just did a few of these RPC and home RPC in prior posts the past few month... I'll get em' and post back links. It's just a hoot to fight w/ the power-co for a few months to replace the pole transformer. (it'll make sense ) Good to see your still around and playing. Still a fav post the past year.
You can buy the oil restrictors too, along w/ the line. I wanna say $13 each? Ping if you need a PN.
Someone also once noted that there is a oil carry line inside a protective plastic line. NEver really looked. So get the right ID/OD for the oil line. (if this is accurate or not?)
Gimme 5. Dogs wanna go out. bRB...
This was from Sept. and has some good stuff.

Odd- Not sure why.. but I'm not finding all my posts on search here. So putting some bullets here.
Compressor start ups cause issues. locate as close to breaker source as possible.
the Wildleg should go to the middle tap. (so it's been listed on posts in the past). someone can verify maybe?
The difference from the wildleg to the single phase can be an issue. it was for us. Phase-a-matic voltage stabilizers really helped there. (Zoro sell's em. and look for a 15% discount code!!!).

I ended up going with the american rotary adx 60, I upgraded the whole house to a 400 amp single phase panel, and put in a 200 amp panel in the garage. im running the phase converter off of a 200 amp breaker right at the top below the main breaker for the sub panel, so the resistance should be minimal. I was talking to the haas guy while he was servicing our office mill at my work, and he said the motors are actually rated at 15hp, and have a 30hp drive, so the 60hp phase converter is likely overkill despite the machine having the 30hp branding, and the American rotary recommendation of double the horsepower. My compressor only draws about 15 amps,from the single phase panel, if it causes an issue I can run a dedicated line from the main panel. My main concern is the incoming lines from the pole are a lot thinner than what I used to make the run for the subpanel, so if anything that will be where the voltage drops.
By wild leg I assume you mean what American rotary calls the manufactured leg. I know what the wild leg is on standard 3 phase, I don't know the terminology for the 3 phase legs that comes out of rotary.
I took the y axis ball screw out and its quite pitted, but its not that difficult to remove, so im not going to wait until I get a new one to put the machine back together. I also got a sand blaster and a parts cleaner so I can repaint all the rusted sheet metal.
