Phoney op-codes list?
Richard Milward
Does anyone have / remember the big list of phoney op-codes for
(I think) IBM 360s? It could have been more general than that, of
course. Two that I remember were : HCF - Halt & Catch Fire, and
RWO - ReWind Operator.

I added to the handwritten addenda....
BOA - Branch if operator asleep
BPO - Branch if power off
BCD - Branch if CPU Dead
CRN - Convert to Roman Numerals
SSD - Seek and Score Disk
MR - Munge Register
RSC - Read and Shred Card
SBT - Stretch and Break Tape
RWR -Rotate Word Randomly
and mine...
IWE - Insert Word Edgewise (part of the interrupt system)
If others make contributions, perhaps you could consolidate the list and
post it.

I seem to recall that up until recently (the 3090 series) all IBM Big Iron had
a 1401 emulation feature/option available and that many DP shops were still
running their 308Xes as essentially "fast" 1401s.
Anyone know of any confirmable cases of this?

Somewhere in my archives, I still have a copy of the Instruction
Codes and Features for the 360/69. If anyone is *really* interested,
I can dig it out and type it in. To really appreciate it, you must
have some familiarity with the 360 and other machines of that (and
prior) vintage. The "407 Emulation" feature only makes sense if
you recall that the 360/30 had an option to emulate the IBM 1401 CPU,
while the the 407 was an electo-mechanical accounting in use prior
to the 1401. Many 1401s had programs which emulated the 407. Thus,
you sometimes had the 360/30 emulating a 1401 emulating a 407.

BBW branch both ways
BEW branch either way
BST backspace and stretch tape

It was much more general. I've got a nice copy of it printed in three
columns per page of six point text and it takes up about 5 8.5x11 pages.
I pulled it out of Nutworks, a quite good but saddly defunct electronic
magazine. (Damn, don't you hate it when the editor graduates? :-)
Anyway, I should still have a flat ASCII file around somewhere. I can
be convinced to email it, or if there's demand I can post it. It's not
quite as long as the Jargon File... :-)

'Load A and X' - reads memory, puts it in A and X regs. The 'Store A

result of A AND X (logical AND). pretty neat

Michael McClary tells me that on one machine that there was a command
that through the machine into a test mode that could not be left without
rebooting the machine. It's actually name wasn't HCF, but many programmers
nicknamed it that.
I forgot to ask him if it is OK to name the machine, so I won't here.
Sorry.

I would appreciate the old 360 Op Code list....I was at RCA on
the Spectra/70 series...we called our list the Spectra/69 list.
I can remember Rewind Printer, Electrocute Operator, Seek Center
Spindle, Eject Disk, Plane Disk Surface, ReRead and Stretch
Tape, SetFire to (card) Chad, Make Tape Confetti, etc.
I still wonder if the SNA command "ROFF" for Remote Power Off
(for which I presume there is no acknowledgement) was intended
as a tribute to the 360/69 Op Code list.

These undocumented 6502 opcodes are listed in a book by PCW magazine (a British
computing magazine). Can't remember what the book was called - Programming
the 6502 or something similar I suspect.
They made great encryption algorithms though :-) None of the disassemblers
even had a clue what was going on ! Of course, none of these undocumented
calls work on the 65C02 series, so they weren't that much use as they would
never work on BBC Masters (but maybe you deserved that if you bought a Master
rather than a BBC Model B !)

>BPO Branch on Power Off
I always thought that one was a joke. Then I worked on a SEL 32/35.
It had a voltage sensor on the AC power line. If power failed, it
generated the highest possible interrupt. The interrupt routine would
roll the register contents out to memory. By the way, this was core
memory, it didn't go away when the power went off. On power on, it
would wait awhile and then pick up the registers and resume where it
left off!
Before I realized that it would do this, I used to turn it on and key
in the bootstrap loader on the hex keypad on the front panel. Real
computer didn't boot up by themselves, not in those days. One day, I
turned it on and went to get a cup of coffee without keying in the
bootstrap. Imagine my suprise when I came back and found the sucker
running! I was half convinced that it was haunted.
