I don't even remember signing up for the RetroAbout64K mailing list. I haven't seen any actual dicussion in my remembrance. But I do get once or twice a week an email about COCO Nation or some such. Sounds like a hot chocolate enthusiasts group seeking world domination. Anyway I've had COCOs going back. Or 1 that I scarfed from a friend for 20$ (back in 89 I think). I realize it has a 6809 and all, the successor to the venerable 6800. But what can you do with the things? Is there even a color output, despite the name. I can't remember. I only remember playing Dungeons of Daggorath or whatever. The guy I bought it from claimed he programmed a complex naval similation. Yeah whatever.
As to what can you do with it? A local company was running a homemade NC
drill using the (IIRC) Coco 2 with a pair of disk drives to drive the
thing. I bought it for kicks, but never used it.
To ask another similar question, I have a tektronix 2 axis controller
that uses paper tape. Changing the questions slightly, WHY would I use
such a thing? And ditto for an Intel software development system.
I have more than enough nostalgia items to keep me busy for the next
hundred years or so :).

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.

Does anyone by chance have a schematic for the 3/110 main board? Its been
running great until recently where my framebuffer died. It boots right up
to where it polls the cgfour and then stalls. I was hoping to do some
troubleshooting.
Thanks,
Kurt

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?

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 : (
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?
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!
Jan Secker
