List: Just passing this along to any who might be interested. Shaun Halstead is interested in cleaning this out: StorageTek STK-2920 9-track, 6250bpi drives. We have 5 of these, at least one, possibly two, have 100ips boards installed. One may have a SCSI interface, the rest are STK interfaces. ExaByte EXB-8700 8mm, SCSI, worked when last used (2 years ago). Tandeberg Data 1200MB QIC drives, SCSI. We have two or three of these, all worked when last used (>5 years ago). Xerox-branded 9-track tape drives. 6250bpi. These are marked Laser Magnetic Storage International, BY36KL. I believe they are LMSI/CDC model 92181, Vertical mount streaming tape unit (per the maint. manual found at bitsavers.) I have at least 2, maybe 3 of these. One can't read it's own writing. Not sure what the interface is, beyond 2-cable. Could be pertec, could be STK, could be Xerox-custom. 3480 tape drives. One worked when last used, one is parts-only. Also, one of these had a SCSI interface, the other is STK. At least one, possibly more, Aviv Unibus tape interface boards. As I understand it, these boards required a backplane modification in the 11/34's to operate correctly. I have 3 PDP's with these boards currently installed, and at least one NOS on the shelf. Other, assorted gear: Bus & Tag cables and interface cards (ISA and PCI), with appropriate PC hardware and software for print serving. PDP11/34 with floppy/Winchester (8" floppy, unknown HDD), last ran >5 years ago. SMS-1000 w/ HDD, last run >5 years ago, needs software. Tapes. Lots of tapes. 9T 2400', 1200', 600'. Some QIC tapes in various capacities, a few 8mm. Never stored in garage/shed/attic. I have no idea of value, usefulness, or current operational condition of anything except the Cipher drive (dead). I can take pics of any/all if desired. Shipping or pickup would be from Wichita, Ks. Shaun Halstead Microfilm Services, Inc. Wichita, Ks (316) 269-2203

From: Steven Landon <slandon110 at gmail.com> > blah blah blah Return the money for a transaction you won't complete: Shit happens and people move on. Don't return the money for a transaction you won't complete: You're a thief. It's not like you didn't know shipping hundreds of pounds of stuff costs money. Are we missing anything subtle here?

VCFMW: Call For Tables

by silent700＠gmail.com

There's a dual meaning in that subject header: I need to gather table reservations for the show but I'm also putting out a request for actual tables, too. Many of you may remember that last year (and previous) Heron Point ran out of tables before we ran out of people and stuff to put on them. If anyone has one or more folding tables they don't mind lending to the show (you don't have to use it yourself,) we'd much appreciate you bringing it/them along. Put some masking tape with your name on it underneath to make sure you get the right one(s) back. I'll be bringing one 5' folding "banquet" table myself - this would be the ideal size but whatever you have will help. This will allow us to pack the two rooms most efficiently and expand comfortably out into the hallways. The more people and computers we can welcome to the show the better it will be. Extra network cables, power strips and extension cords will be handy as well. As for reservations, I have heard from a number of you but not all that I usually see there. If you'd like table space, let me know your requirements (in units of 2'x5' tables) and demo theme, if you'd like that listed, ASAP. We're going to be tight this year (and that's a good thing) so please give some thought to what you can fit into 1-2 tables worth of space, if possible. Thanks all and I'll see some of you at the 8/30 meeting. -j

Vtserver, pdp11/34, and saving images

by ak6dn＠mindspring.com

Nothing besides running XXDP via TU58EM over this higher speed link. That's all I really use the TU58 for anyway, running XXDP diagnostics. It would be interesting to test running RT-11 over this emulated high speed TU58 link. It has a different s/w driver architecture so it may (or may not) work ok. In any event if the mod is done to the DL11-W you can back off to 57.6kb or 28.8Kb by changing the DIP switches. Those would probably work and are better than 9600b.

Notes-11 for PDP-11?

by dave＠mitton.com

I'm pretty sure had one on RSX. Don't remember what it was written in, but I wouldn't be suprised if a RSTS/E one existed too. Dave.

Fujitsu Eagle

by t.gardner＠computer.org

Anyone have a DEC system with a controller that talks to a Fujitsu Eagle (M2350A, M2351A, M2360A, M2351A). These are modified SMD interface drives that attached to VAX with controllers from Emulex and others. Alternatively, anyone just have such a controller

FS:AmigaMini- Thin Client- The Dedicated Amiga Emulation machine

by slandon110＠gmail.com

I started a project a a while back to come up with a nice way to run Amiga Emulation. Came up with a prototype recently based on an HP t5735 Thin client that has enough power to run the emulation smoothly. Finally got all the bugs worked out and I thought id sell some that I built up. I call it the Amiga Mini Specs are as follows HP T5735 Thin Client 1GB RAM, 1GB ATA Flash Disk, Holds Windows Embedded 16GB flash disk, Holds UAE and all other relevant files 8GB USB Flash Drive that mounts in workbench for easy file transfer. Over 1000 WHDLoad Games come preinstalled on the 16GB flash drive, Along with 500 Demos. AmigaForever is also included. Comes with ClassicWB 3.1 UAE installed and the system boots into Amiga Workbench 3.1, The cool part is it has Picasso emulation, so you get 32bit color at 1280x1024, Looks great. Boots right into Workbench 3.1 as soon as the system powers up. You can also configure UAE by just hitting the F12 button. Here is a youtube of the prototype http://youtu.be/HPRHPqXSgRs The internet is fully functional as well. So you can browse the web with AWeb, Chat on AmIRC with it. Transfer files via FTP or share files via SMB. Im asking $120 shipped anywhere in the USA. Good for peeps who want to see if they like the Amiga Platform, and its cheaper then finding a tricked out expanded amiga. I have 5 available, If there is demand for more I will build more of them.

Anyone with an EPROM burner out there? Need a chip programmed..

by drlegendre＠gmail.com

The KERNAL ROM in my Commodore SX-64 took a dive, and I don't have a spare. Far as I know it can be replaced with simple 8K PROM/EPROM. I've got the correct .BIN file - is someone willing to make a kernal ROM chip for me? If you don't have a suitable chip in your stock, I'm sure I can turn one up on ebay and have it sent to you. (And no, it's not the same as the C-64 kernal rom.. close but not identical.) TIA for any assistance. Please feel free to mail me off-list.
