Thanks. I thought that the 4341 had it, but I couldn't find anything on bitsavers to back that up.

I'd like | to add that to the wiki [[IBM System/370]] article. In hardware, it was the 3033 (as well as the 3042 Attached Processor), as well as a hardware assist MES for the 3031. It was also, of course, also supported on the 3081 (and all processor models thereafter).If I remember correctly, this support was not offered for the 3032 in any form.

In software, it was supported on any System/370. The ABENDs were intercepted by FLIH and the unsupported instructions and control registers emulated. This worked on my 370/158 at the time (1980). -- William Blair Sugar Land TX ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
