Do I need a new ROM tower or is it possible to burn whatever special ROM it needs?
Brain is rusty on this.. but if I remember right.. U182/U183 could be replaced directly on the board using 27C4096 / 27c2048/ 27C220 type eproms.. I've done this before eons ago.. also some A3000's have the ROM0 ROM1 labels reversed.. so keep an eye on that as well..
Units that had the rom tower would adapt the "usual" Amiga ROM / 27C200 pin-out to U182/183.. Tower was there since U180/181 on the motherboard was not routed properly on the PCB..
