1 ENTER 2 ENTER 3 ENTER 4 ENTER 5 ENTER 6 ENTER 7 ENTER 8 ENTER 9 ENTER
+ + + + + + + + (8 times)

Now, if you get

• 68 then you've got type 1 (classic RPN) with 4 stack levels,
• 54 then you've got type 1 (classic RPN) with 8 stack levels,
• 45 then you've got type 2 (RPL) with a large ('infinite') stack,
• 60 then you've got type 3 with 4 stack levels.

There are a few other RPN flavors.
For example, if you get

• 81 then you've got a calculator with 3 stack levels and Y as the accumulator, such as the HP 9100A/B or HP 8010
• 26 then you've got a calculator with 3 stack levels and no top level replication, such as the NS 4510
• 33 then you've got a calculator with 4 stack levels and no top level replication, such as the NS 4640
  

I don’t have access to an early HP desktop calculator, but judging from the manual I would expect one of the HP 9100 or 9800 series to produce 72 in this test.
Who can do the test on the hardware?
