Sure, at least it's both historical and Unix. The CH11 device is for all SIMH Unibus computers, so VAX, PDP-11, and PDP-10 (KS1).

Why oh why is there such a high correlation between archaic obsolete systems and sheer hacking joy?

I'm not doing that hacking, too old and burnt out, but for those who still have some juice left my guess is it is fun because the older systems were pretty simple. A kernel and a few well known device drivers is not a lot of code (the millions of lines of Linux kernel code is almost all drivers). ^ permalink raw reply [flat|nested] 8+ messages in thread

I've always found it easier to help someone else solve their problem than it is to solve the same problem for myself. I attributed that to the desire vs need. Maybe the attribution should be more to the company than the singularity. -- Grant. . . . unix || die [-- Attachment #2: S/MIME Cryptographic Signature --] [-- Type: application/pkcs7-signature, Size: 3982 bytes --] ^ permalink raw reply [flat|nested] 8+ messages in thread

Much like many of these old systems, owning one is far from practical, let alone a functioning one, but emulation is so convenient. Just as dynamips is another great hero of emulation, bringing all kinds of networking topologies into play. I guess it's also a break from the x86_64/arm64 boring of the day to day.

I have also tested MINITS running on the pdp11 simulator. MINITS is a Chaosnet gateway, router, terminal concentrator, graphical display, printer server, etc. At one point there existed Chaosnet patches for PDP-11 Unix V7, but so far I haven't found them. ^ permalink raw reply [flat|nested] 8+ messages in thread

The hackmem describes all the changes needed, but it's a poor substitute for the code.
