Only having 1-bit datatypes is highly limiting. With more datatypes, you would of course need more opcodes, eg:

• add 8-bit datatype
• opcode to add/subtract/multiply/divide from the stack
• opcode to compare numbers from the stack, pushing true/false as the result (greater/less/equal)

If you had these...I think I could build my wanted Counter IC without resorting to Java :)
