    Troubleshooting DEC Pro 350 w/ Ultrix-11

    ultrix is aware of disk geometries but i think you should be able to mount any properly formatted ultrix disk on any properly working ultrix install, unless i'm misunderstanding the question? i.e. an image of a formatted rd53 should still be usable in simh as an rd53, i would think

    Best "starter" CP/M machine? (and looking for KAMAS outliner software)

    kaypros are fun and reasonably interesting machines, with the bonus that they're very common and relatively cheap. i see good ones on ebay going for $250 or less regularly and i was able to get a 2 and a 2x from a local guy for only $300, definitely not a bad choice

    issues generating RT11FB for TSX+

    that's definitely a thought, SIMH has SET THROTTLE, i'll have to play around with that a little bit

    issues generating RT11FB for TSX+

    i can see the clock ticking, though, and i think the clock is enabled by default unless you explicitly disable it. it's there in my config: sim> sh clk CLK 60Hz, address=17777546-17777547, vector=100, BR6 .tim 00:00:50 .tim 00:00:51 .tim 00:00:52 .tim 00:00:52 .tim 00:00:53 .tim 00:00:54

    issues generating RT11FB for TSX+

    was able to get TSX generated and linked, but i'm getting this: .r tsx ?TSX-F-Computer line time clock (50 or 60 Hz) is not working the 60hz clock is in both SIMH and RT11 configs, and i'm not seeing anything i could modify in TSGEN.MAC. the install guide also doesn't say much, beyond the fact...

    issues generating RT11FB for TSX+

    if unloading the unused drivers is just as good then i'm happy to stop wrestling with the sysgen, i have a feeling if i keep trying i'll end up in a padded room :p thanks all!

    Grid DOS V3.30 needed - and maybe other versions

    buy one of these specifically and you'll never regret it: https://www.ebay.com/itm/235778894921 there are a lot of similarly priced new ones on ebay with fast shipping; they're all crap, these are bulletproof

    What was your greatest or wildest needle in a haystack poor score, or pick up?

    somehow forgot: a while back i got an rs/6000 off of ebay and had a good conversation with the guy i picked it up from (he was a mainframe software developer and was surprised that people were into them as hobbyists), eventually he got around to checking out my personal site and saw that i...

    How to best clean a H7864 power supply? [BA23 Box]

    the only caveat with the fan swap is that you either have to use both of the molex power supply cables in the chassis, so you cannot run fixed drives. it's probably possible to hack off the end of the noctua fan cable or otherwise mod something up, but i did not try- if you manage to get that...

    Mystery DEC software

    P/OS was pro only, but it's just a very whittled down RSX11 so you aren't really missing a whole lot also, al runs bitsavers, the images should be small enough that you can just email them to him, maybe in a zip archive

    How to best clean a H7864 power supply? [BA23 Box]

    the BA23 stock fans are good but are a bit noisy, depending on your configuration you may be able to replace them with more modern ones like myself and others have done as long as the airflow rating is correct: https://forum.vcfed.org/index.php?threads/new-fans-for-my-micro-pdp11-23.1247515/ i...

    this, they own the heathkit trademark and all associated IP and sell access to it, so they have a vested interest in making sure the filthy peasants who aren't willing to fork over $25 for a manual that should be free never get it
