- Well, there was an article in Datamation in the mid 60s that was the first
- I remember seeing of lists of funny instruction mnemonics. But it was
- probably years in gathering.

- HCF Halt and Catch Fire
- BST Backspace and Stretch Tape
- XPI Execute Programmer Immediately
- ACA Add and Clear Accumulator

- are a few of the ones I remember. Now in the Burroughs B6500 there are
- a couple that are for real -
- WHOI - read processor identification register
- HEYU - interrupt all processors

- Hey Jim, when did you write that??? Did you ever find a fuller list?? The
- date on this archive (distributed fourth or fifth hand as an LBR file on an
- RCP/M system in Norcross Georgia, downloaded by me in 1988) is lost, because
- I rearchived it in ZIP format, which destroyed the date. I've been wanting
- to ask you that question ever since, but not until now have I had the
- capability to ask... :-)
