Hi everyone!
I'm working on a project where I need to build an RS-232 to Current
Loop adapter. I've seen some schematics on-line and the parts list
seems pretty small, but does anyone have a specific set of
instructions and schematics that they trust? Or does anyone in the UK
have a spare adapter they'd like to send me? :D
Thanks!

If it’s specifically to interface to a model 33 Teletype, here’s a design that works well and is pretty simple.

Are there any 3D printing experts hanging around here? I need help.
I want to print things like a bracket to mount my FreHD in a disk bay.
Some other things, too. The problem is the STL file wants to print
these items
vertically instead of laying flat on the table. Needless to say by the
time it gets
to the part where it wants to print the faceplate the object is unstable
or, in some
cases, completely tipped over.
Is there any way to change the orientation of an object on the table
using just the
STL file?
I have a Creality Ender 3 printer and their slicer software.

Can anyone tell me what I picked up at a NH hamfest this weekend for $20? I see it says RL01/RL02. I have two RL02 drives and some platters. None of which I have gotten around to trying. Other than a copious amount of pine needles, what can this be used for? Or maybe the right question is, should I not use it for fear of destroying an RL platter?

Hi,
a friend of mine is currently working on a FPGA implementation of the
CERES-3 workstation (cpu-ns32k.net/TRIPUTER.html#Ceres).
He currently lacks of information of the RTC chip M3001 which was
manufactored by Swiss company Microelectronic-Marin.
Does anyone have a pointer to the datasheet ?
Thanks Bernd
I have at least 5 in my stock. I could easily part with one or two. I would rather trade rather than get cash. Do you have anything to offer in trade?

I'm interested in recreating MMI application note AN-114 which describes
adding an sn74s516 mult/div/acc chip to a 68000. Unfortunately, I haven't
been able to find an sn74s516 in the couple of years I've been looking.
Does anyone have some they'd be willing to part with?

I saw a clip of this project on DW News:
https://www.memory-of-mankind.com/
They're recording works for posterity on ceramic tiles.
How's that for preservation?

I learned today about Dave’s Old Computer website http://dunfield.classiccmp.org/ which is listed as a subdomain under classiccmp.org. I wasn’t aware of subdomain sites. Can any one list any other ones or is a list of sites available ?
