When you want a recap and that buster upgrade let me know. I can also solder in the required GALS in the new sockets for your ROMY if you havent done it. I would be glad to do it all for you. My prices are very fair.
As for slots for all your gear, you can get a tower and a bussboard for it. This is a great value and is in stock at Elbox:
