on 02026-03-18suggestions for running #CICS for #transactions in #emulation. “it depends on the installed operating system, if you manage to get hold of a copy of z/OS, then it's accurate. most people run the old MVS3.8 system that was the last release that was out there in the open without restriction.”
on 02025-11-11I think "Kicks" is a #CICS clone or fork? For playing with #transactions on your IBM 360 in #emulation I guess. “KICKS is an enhancement for CMS & TSO on IBM mainframes (or emulators) that lets you run your CICS applications directly instead of having to ‘install’ those apps in CICS. You don’t even need CICS itself installed on your mainframe. KICKS provides a high level of source code compatibility with CICS. You can migrate applications either way between CICS and KICKS simply by recompiling.”

on 02017-03-22simavr does #AVR #emulation with timing and dumps out #VCD files, a sort of built-in virtual logic analyzer. The instructions in the README here produce somewhat less debugging output than shown in the current version of simavr, and it took me a while to figure out how to open them in gtkwave, but they do work. Also the VCD format, which sigrok supports for both input and output, seems super simple.
