Whilst we are on the subject of the 28C, I have a couple of
questions that maybe someone (Corvallis?) can answer.
1. What does opcode 80810 do on the new Saturn processor?
2. HP-Journal (August issue I think) states that there are
17 objects defined so far for RPL; I count 19 object
prologs. Here is my list, perhaps you can correct / fill
in the missing bits.
Prolog
Address Object
------- ----------------------------------
02911 Short integer (5 nibs)
02933 Real (16 nibs)
02955 Extended Real (21 nibs)
02977 Complex (32 nibs)
0299D Extended Complex (42 nibs)
? 029BF Byte (2 nibs)
? 029E1
02A0A Array
? 02A2C
02A4E String
02A70 Long integer
02A96 List
? 02AB8 ROM/RAM pair
02ADA Algebra
02C67 'Program' (new thread)
02C96 Assembly code
02D12 Global name
02D37 Local name
? 02D5C ROM pointer (11 nibs)
3. In the 'lex' file header (to use 71 terminology) what is
the last 5 nibbles supposed to be used for. Its a bit
difficult to work out since all of the internal files
have them set to zero. Are they an offset to a poll
handler?
