So... Here we go.... :-) For reference, TALOS is my pdp11/83 system from way back long ago. It's running real hardware, RX02, RL02, a 330mb ESDI disk, TK70, and 4mb of parity RAM. Runs with 2,000 blocks of cache, read-ahead of 5, and purrs along pretty nicely overall. The next step is to get 4mb of PMI memory as the 1mb board I have *is* faster than Q bus memory but there's not a lot I can do with DECnet and TCP/IP in only 1mb. But finally I can get to my system without an RS232 cable. And fix the time offset. But progress! (Now I need to back it up) Thank you Johnny for writing this code.

USB Attached 5.25" drives?

by Zane Healy

I’m now aware of the GreaseWeazle, but what I’ve not seen is if it allows standard access to the data on a floppy, or only provides a way to image the disk. With an USB attached 3.5” floppy the disk mounts on my Mac, and I can easily pull files off the disk. Does this work with the GreaseWeazle and a 5.25” floppy drive? Zane

HPE StorageWorks DAT 40 USB Tape Drive questions

by Stan Sieler

Hi, Has anyone used an HPE StorageWorks DAT 40 USB Tape Drive on a Mac / PC / Linux as a "standard" tape drive (i.e., I want to be able to "dd" from one, not use some HP provided backup package). (I have no interest in writing to tapes, BTW) I just got such a drive today (#1), and hope to use it to read 10 to 20 year old DDS2 & DDS3 tapes in a "tapecopy" (semi-raw data to disk file) manner. (The DAT 40 is a DDS4 drive, which supports reading DDS2 and DDS3 ... newer drives don't support DDS2, and I've never seen a DDS3 on USB.) I found HP's cache of docs/drivers for the newer DAT 72 drive, and some indications that the -40 and -72 are essentially similar (other than the -72 being a DDS5 drive). I'd prefer reading the tapes on a Mac, but if Linux/Win is needed, I'm hoping I can use a virtual one :) thanks! ---- 1. I'd try it out today, but my main computer is packed up, waiting to move to a temporary house, because we have to move out of our house due to water-damage driven kitchen remodel : (

IBM PC/XT and NEC "gold" tam

by skogkatt007＠yahoo.com

I have an xt mobo and some portion is populated w/NEC 4116 or 4164 chips (but 4116s were specific to the 5150, no? It's not in front of me). There are a bunch on the board, not sure if it's all the ram. Was this typical (I'm sure that wasn't the case). Is this an example of an early 5160? Why did they goldnplate the covers?

Searching documentation for

by jf.secker＠gmail.com

Hello List, I have made an implementation of Sytse van Slootens PDP2011 MINC system ( https://pdp2011.sytse.net/wordpress/pdp-11/minc/ ) on a Terasic DE10 Lite board. There exists documentation for the MINC system, but it is not complete. Schematics and/or user guides for the DEC MINC modules MNCAG and MNCTP are still missing and not to be found in the usual places. Maybe some of the contributors to this list own a MINC system wich contains these modules. If so, they might have the documentation I am looking for and are willing to share these. Thanks in advance!

OT: boxed board games (Avalon Hill, etc.)

by skogkatt007＠yahoo.com

Looking for a recommendation for an older (or even newer, some d games have been rereleased anyway) for a either historical boxed table game ~A.D. 400 - 1300. Or something sci-fi (nothing tv or movie related though).

But that's putting and 8" drive on a 34 pin interface. That works great.

scsi

by skogkatt007＠yahoo.com

How do you know if a termimation is suitable? Is connection all you have to worry about? I have an HP Ultra 320 drive, a 320/m compliant adapter (id jumpered to 2. Does a this need to be 0 for a single drive setup?), the cable with an ultra 320m terminator (" LVD + SE ACT NEG + HVD ISO " printed on it). Everything seems legit. I want to plug this into 2 different serverboards, an Intel SCB2, dual PIII, dual ultra 160/lvd channels, and an IBM xseries 350/Netfinity 6000 (8682 serverboard), quad PIII xeon slot 2 cpu's, similar scsi capability. Whaddaya think?

Contact information for Scott Lurndal? (or V-Series MCP/VS documentation)

by Andrew Warkentin

Does anybody have any contact information for Scott Lurndal? I'm trying to get his V-Series emulator working (I downloaded it quite a while ago), but it doesn't include any documentation and his wiki is no longer available (and a lot of pages weren't archived). I can run it and get to the coldstart screen but I'm not quite sure what to do from there. Bitsavers doesn't have much documentation for Burroughs medium systems.
