Thank you very much, Bajin. And apologies, I should have followed up - some months after starting this thread I did find another SIMCHECK with firmware version 2.40, and it does indeed work with the 72 pin unit. So I'm overdue to extract and dump the EPROM and share it for comparison purposes.

I recently went through this, trying to find a compatible keyboard for a Tek 4207 terminal. It was quite a slog trying to determine which keyboard models were compatible, and had the correct connector, then finding vendors that weren't just playing SEO games because of the scarcity/higher...

Person I contacted in .de doesn't seem to have an appetite for the MX300. I wonder just how bad shipping would actually be... Might be a bigger problem if, like the PC-MX2, it requires a Siemens terminal for the console?

Would love to provide a home for the Siemens MX300, but I doubt shipping across the Atlantic is practical. Let me see if somebody I know is interested...

It is fun to poke through older systems, or there would be a lot fewer of us here. Nice to be reminded of a time when Linux (used broadly) was on the outside looking in, and distros like RedHat were meandering towards respectability. But you will find gems scattered around liberally the further...

Something like top or ofiles (precursor to lsof) has to access kernel data structures, but early on they were written on or ported to 4BSD. I believe I grabbed top v2(.1) out of comp.sources.unix volume 7, and an archive is available on archive.org. Excellent question, but unfortunately I'm...

Might be interesting to see if they just followed the application note, assuming it came out before the 440x was finalized. Only reason I went for uemacs 3.8b was that I found those sources (after I found and built 3.7). If I'd had a later version on-hand, I would have given it a try. I'm not...

Oh, uhm, which I believe you are very well aware of... 😅

The 6130 uses the typical NS32000 chipset - the NS32016 CPU, the NS32081 FPU, the NS32082 MMU, the NS32201 TCU (timing control unit), and the NS32202 ICU (interrupt control unit). Mine both appear to be clocked at 10MHz, but I've read descriptions of 6130s where they were clocked at 8MHz, and...

I've continued playing with the Tektronix 6130 I posted about last year (and the year before), and I finally put together a web page with some of the links, information, and whatnot I've been collecting. Figured I might as well mention it here in case somebody finds a system down the road and...

I'm assuming that you're looking for the kinds of random PD/FOSS software that we all used to build when setting up SunOS 4 systems out of the box at a new site. Have a look under http://ftp.gnu.org/pub/old-gnu, you should be able to find versions of packages that were released while support...

Nice score, and thank you for sharing the STL for that ZuluSCSI bracket! I hope to make use of that in my 9000/380. (We'll see if that ~33% clock upgrade tempts me down the road...) I took a look to confirm which model I had, and noted that there appears to be a second socket (for the heatsink...

Hi Egon, I opened up the 5000/240, and found a PLCC under the middle TURBOchannel slot. Didn't remember that - I'll need to find my bag of extras with the extractor and adapter before I can read this. --S.

Don't know if they'll be different from whatever may already be online, but I'll try to get a couple over the weekend.

Circa 1994 we had a copy of SimCity/Micropolis running on a few UNIX systems at an X Windows software company in Cambridge, MA, USA. Can't recall if it was the demo, a "courtesy" copy between the companies, or abused. Reactions seemed to mostly be of the "Oh, that's neat. Well I've got...
