Peter, How exactly do I BOOT the SC-40 from tape? You're the only onw who knows. ;) I have a compatible HVD tape drive and a properly-written tape...now I just need to know how to boot it. -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

TOPS-10 KS10 Ethernet Monitor

by b4＠gewt.net

Hello, I've been attempting to (likely incorrectly) get the DEUNA emulation working in SIMH's KS10 simulator. Current status: * Exists * Has an address * Has a vector * Can be enabled * Can attach to host interface ...and that's as far as I've gotten. Currently having issues getting TOPS-10 to successfully link for KS10 with ethernet support. Anyone have a pre-genned MONITOR executable? -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

TOPS-10 KS10 Ethernet Monitor

by wilson＠dbit.com

From: Johnny Billquist <bqt at softjar.se> >I'm curious on exactly how a DEUNA/DELUA works in a KS-10. Does anyone >know? Does it do 8-bit-byte DMA to the 18-bit memory, leaving the top >two bits alone. Or does it only work if it do word DMA (would be >strange, as the controller itself can send and receive odd byte length >ethernet packets). This is what the BLTBU and BLTUB instructions are for in the later microcode (converting between sensible PDP-10 memory and the mishmash you get as a result of DMA through the UBA to a 16-bit peripheral). Since a DELUA is not 18-bit-data-aware, it ignores the high two bits of each 18-bit halfword when doing DMA. >Is there some potential problem with regards to a PDP-11, which have two >parity bits for data, which are used for actual data on a KS? (If I >remember right.) IIRC you're OK as long as you don't set those bits in memory that the DELUA will read. I feel like the Unibus documentation changed at some point, between whether PA/PB are actual parity bits (I think that's what the very early doc said), vs. being parity *error* bits (and I think PB isn't even really used -- PA asserted means there's been a parity error detected in the current DATI/DATIP). I could be wrong about all of this. John Wilson D Bit

Last month's Ebay auction for DEC VAX Ultrix, NETBSD software, TK50 cassettes, DECDirect Disks

by jim＠deitygraveyard.com

With all the recent Ultrix talk I guess it's safe to assume nobody here won this auction last month: http://www.ebay.com/itm/321694487216 . Right? (I think) I downloaded an Ultrix 4.5 CD a while back so I'm really hoping to get the Software Products Library CD. Among other things I want DECNET-Plus. And I want the Documentation CDs. And... I really wish I had gotten in on that auction. :( Jim

ULTRIX DECNET LMF?

by sampsa＠mac.com

Any of you happen to know what the correct LMF code for ULTRIX-32 4.0 DECNET happens to be? I know a guy who knows a guy with pakgen *cough* so I could get the necessary licenses but we don't know what the product codes are.... Sampsa

Ultrix

by mcguire＠neurotica.com

By the way, since we're discussing Ultrix...I just remembered that I have 4.3 and 4.4 CDROMs for VAX. I just made images of them. Let me know if you want 'em.. -Dave -- Dave McGuire, AK4HZ/3 New Kensington, PA

For a while we were Frick and Frack but we managed to >get it together. Thanks guys! 'Twas great to meet you Steve. Dave has often spoken of creating an uber-cluster at VCF East. Let's do it! As for me, I reside about 12 miles away, so it's no issue for me to get to InfoAge. In the later '80s and early '90s, I provided VMS support at Camp Evans when the Army was still in active occupation of the site. I would love to see a huge DEC presence at VCF next year; especially, VMS kit. I also, albeit Alpha and Itanium are not vintage in the mindset of those running VCF, would love to demonstrate the seamless integration of VMScluster across the different architectures. But, regardless, I would very much contribute DEC kit for next year's VCF. -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG I speak to machines with the voice of humanity.

The other end is my site >with plenty of bandwidth and even more coming. It will be a 100 megs >down / 40 megs up shortly. I have other passions outside of computing too. One is music. For more than a decade, I've been hosting the Aural Moon Progressive Rock internet radio site and doing many/most of the technical efforts to keep it going. My title there is: Janitorial Services and Restroom Supplies; as I keep it all neat and tidy, and free of the script kiddies and forum SPAMmers. Anyway, a Philadelphia FM DJ has a show which Aural Moon rebroadcasts on Saturday evenings and replays on Tuesday. He has also, as an Aural Moon exclusive, done live concert feeds. For this, I've contacted the local cable internet providers and have had cable internet drops installed for the duration of these events -- typically, weekends. With a little bit of preparation, I've had sufficient bandwidth via these carriers for the up-feed to Aural Moon. The installation and fee for the last three-day event's internet was less then $100!!! I have a 4U portable rack with a Cisco router, APC UPS and sundry other bits I've needed for doing remote site live gigs. Think about it! I don't know who is providing internet to InfoAge but I've found it to be slow and unreliable; at least, the wireless on the campus seems to be. -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG I speak to machines with the voice of humanity.
