It is the same as the mod 8, the arachnid is the base of a bunch of the FV-1 based circuits. Some have specific requirements that won’t work or won’t work as intended ie. rainbow machine, hydra, organizer. The chip that runs 8 options is the eeprom. These are totally customizable and interchangeable. @PedalPCB has a section in the FV-1 where you can create your own 8 sound eeprom.

Ok and how could I go about finding out the limits? I guess that depends on the pcb I decide on first. Do you know of one that could be .....how to put it ? Completely inter-changable? I guess I mean (again if I'm getting right) a board that will accommodate pretty much whatever EEPROM you toss in there ? Can you use more than one EEPROM at the same time? Or would there even be a need or reason to? To me what I'm talking about sounds more like a breadboard thing popping this in pulling that out but that's why I'll always use sockets for all the customizing places on my builds. Even if I dig the final sound I really like the fact that any given moment I could do some, albeit mostly subtle, changes to the build so as you could tell the option for that for me would be very cool

Like @carlinb17 mentioned, there are a few effects that won't behave properly with any other PCB than the one they were designed for.... The Deflector, DMD-2, Hydra, Organ Donor, and VHS were all designed specifically for their EEPROM/PCB combination.
The HAARP algorithms will work in the Arachnid / Pythagoras PCBs but it isn't ideal since neither have the "Direction" switch. (One of the knobs would behave as the Direction switch, which might be a little awkward)
The Leprechaun uses one of the internal effects of the FV-1 and doesn't require an EEPROM at all.
The Daydream, Spatialist, Unison, Radium Springs, and any effect in the EEPROM Builder can be used in the Arachnid or Pythagoras PCBs interchangeably.
Short version, any of the effects listed in the EEPROM Builder tool can be used in the Arachnid or Pythagoras PCBs, but any others may or may not behave as expected. If you plan to swap EEPROMs go with the Arachnid (8 effects of your choice) or Pythagoras (3 effects of your choice).

Thank you I now have a clear picture and a decision. The Arachnid. Thanks again

I just built a Spatialist and it is amazing. And you're here to tell me I can just customize and swap out EEPROMS in endless combinations? Unreal.

Yup! I have 2 Arachnid platforms on my board; Spatialist and Module 8 with 3 additional EEPROMS. You can also get pre-programmed EEPROMS from Mas Effects: https://shop.mas-effects.com/collections/all/products/custom-fv-1-eeprom
