How to localize bad RAM

According to Amiga History Guide’s A guide to Guru Meditation Error Codes [archived], #81000005 means “corrupted memory list,” and since it threw the error at the same address twice, I assume that’s a bad RAM chip.

The question is, how do I correlate the memory address to the particular memory chip in which that address resides?

A1000 all set up

Really liking this machine. Loading the Kickstart from disk is an extra step, but since you don’t have to re-load it when rebooting, it’s not that big a deal.

Video output seems to be cleaner than my 500s, this is with a non-buffered straight A23 RGB to VGA cable, and it looks about as good as 640x200 can on an LCD.

Today’s haul [A1000]

Got a VERY good deal on this CIB A1000 with all original software (Kickstart/Workbench 1.1, 1.2, and 1.3) and manuals at the DFW Amiga meetup today. The AmTRAC trackball is a big win, I love a trackball and didn’t know one was made for the Amiga. It also came with a 1020 5.25” floppy drive, which is neat because I’d like to see how Transformer performs with an accelerator.

Ended up selling the 1702 that I don’t need to another group member who has been looking for a reasonably priced one for a while, so I was able to recoup some of the purchase cost and give him a good deal, which always feels good.

The real win for me is that this will save me quite a bit of real estate on my retrocomputing desk as it will be replacing an A500. The garage gives it a smaller footprint when not in use AND things can be stacked on top of the case.

Can’t beat that with a stick.

Whyyyyyyy are the flushing volumes from Bambu not available in Orca??

These are parameters I am very interested in changing, but I don't see them in Orca in filament settings.

Orca tolerance tester hexagons coming out all curved

I don’t expect super sharp interior corners, especially with a 0.6 nozzle, but the sides of these hexagons are profoundly bowed, to the point that I’m not sure they’re useful datums for determining shrinkage. Bambu H2D, both ASA, although results are similar in ABS and HIPS.

By profession I’m a machinist, so really what I want is for the printhead to slow down before entering a corner, same as if I were cutting a pocket on a mill, but I don’t see that Orca has a setting that does that.

Anyone ever strip the coating from a PEI plate?

I’ve been thinking about putting a WhamBam PEX surface on the back of my Bambu Textured PEI plate, since having a duplicate surface on the back is useless to me and my print throughput isn’t fast enough to really need a second plate. I also have a nasty scratch on one side, so there’s not much to lose.

Has anyone ever stripped the PEI powdercoat off a build plate, and if so, how’d you do it?

How do I name/organize filament profiles so the full name doesn't show in the dropdown menu?

I'm really struggling to get my head around this, and I cannot figure out what the program wants from me.

Some filament profiles, when I switch nozzle sizes, continue to just display <base name> in the dropdown, but some display <base name> for one nozzle size, but the full profile name for a different nozzle size.

If I save a new profile from either the system profile (PolyLite ABS @ H2D ) or the existing custom profile (PolyLite ABS @ Bambu Labs H2D 0.6 nozzle) named PolyLite ABS @ Bambu Labs H2D 0.4 nozzle, it will only display the full profile name in the dropdown.
I've checked the printer profile dependencies, PolyLite ABS @ Bambu Labs H2D 0.6 nozzle has dependencies checked for all the nozzle sizes I use and will show up in the list with just the base name when any of those three nozzle sizes are selected, which is hunky dory...except that adaptive pressure advance and flow rate settings aren't the same for every nozzle size, so I need to have different profiles for each nozzle size.

The way Orca Slicer (and by extension Bambu Studio) handle profiles is maddening, and seems needlessly complex. Why can't I just name the profile what I want it to display as? Why are dependencies a thing, since the dependent profiles don't inherit any changes from the system profile, which is static? Why does the full name get truncated sometimes in the dropdown menu, and sometimes not, and why does manually naming a profile according to that pattern not result in that same behavior? It doesn't need to be this complicated.

Is there ever a use for dynamic mics in field recording?

I often record a lot of very quiet sounds and ambiences (wind rustling in leaves, wind turbine blades), so I've chased low self-noise from a Tascam DR-100 MkIII to a MixPre6 and a pair of CM4s to finally biting the bullet and buying a BP4025 (a very large expense for me as a non-pro), but I was thinking that the relatively low self-noise of a dynamic mic with a high-gain, low-noise preamp (like the SD Kashmeres in the MixPre) could accomplish a similar goal.

Are dynamics ever used professionally for field/location sound, and if so, in what situations?

Repeat character to position, rather than number of characters?

I want to pad a section title line in a config file with `=` up to a specific character position (specifically, column 64). Since the title text is of inconsistent length, a normal &lt;n&gt;i &lt;char&gt; won't do it.

Example of a title line formatted the way I want it:

More exciting things in the works over here at A16

Combination round/square DIN replacement power socket for Amiga (and C128). Contacts modified for the non-standard CBM pin footprint, retains full compatibility with original square power plug but also allows use of much cheaper and easier to acquire 262º 8-pin DIN 60574-18 connectors. The Commodore square guy is really just a heavy modification of the 60574-18: CBM pin 1 is in the position of DIN pin 7, pin 2 in position 4, pin 3 in position 5, pin 4 in position 8, and pin 5 in position 6.

So far I have designed and 3D-printed new connector shells and bent one of the existing contacts into shape for the non-standard pin location of contact A2/DIN4. I'm currently talking to an Alibaba supplier about the feasibility of a custom run of their DIN connectors (the ones I'm taking the contacts and backing plate from) all properly injection-molded and with nice rounded pin ends.

Filthy commerce is not allowed on reddit dot com, so you'll have to DM me if you have further questions. ;)

So, when is the class-action suit getting filed?

Bambu locking down hardware mods and cloud printing is a pretty clear instance of changing the contract after the fact, and they should have to answer for it. We bought a printer that worked with our software, software that has equal legal footing with Bambu Studio, and after we were using it, they locked us out with the lamest IT excuse there is—“security.”

Sure, we don’t want our printers getting hacked, and it’s great that there’s the turnkey software setup for people who just want to push button and receive print, but locking those of us who want more control out of our own equipment is not necessary to make that happen, and it is the removal of a feature we paid for.

How does one initiate a class-action suit?

What’s the highest chamber temp for PETG?

Trying out PETG as a support material for ABS, and it’s jammed up the extruder on my H2D hard enough to require printhead disassembly twice now, stretching out between the extrusion gears. I suspect it’s softening due to the 60° chamber temp (and sitting there heat soaking since it’s loaded in the second hotend), but I’ve seen quite a few things written about using PETG instead of HIPS as a support interface material for ABS so there must be a temperature that’s a workable compromise for PETG without the ABS print warping.

H2D, 0.4 stock nozzles, 60° chamber temp for ABS, Inland PETG+ on the spool holder feeding left hotend, Inland ABS+ High Speed in the AMS feeding the right.

What are folks’ experiences with this combo?

Color-matched ABS/ASA 3D printing filament

Does anyone have a source for ABS/ASA filament that's a color match to the A500 and/or A1200? I've seen a few options mentioned for PLA, but I don't print PLA except for rough prototypes. Filamentcolors.xyz has let me down, the closest they've got is Prusa's Signal White, which doesn't look beige at all.

WB 2.1 HDSetup crashes on A600 or FS-UAE

I'm trying to install WB 2.1 on a 500MB IDE drive, with no luck. Attached to the A600, it doesn't show the drive in Workbench, and the HDSetup crashes with no message when I try to format it.

I connected the drive to my Mac with an IDE-USB bridge, to verify that the drive isn't bad—no issues there, takes a format fine. Deleted the HFS volume, added hard_drive_0=/dev/diskr in my FS-UAE config. WB 2.1 Install boots fine, sees the hard drive as an NDOS disk, but HDSetup still crashes the same way. 

What's the deal here?

List of CRT VGA monitors that support 15kHz horizontal sync?

Y’all might be the ones to know this. Is there such a list? I have heard people say that most any CRT will sync at 15kHz, but I’ve also heard that some won’t. Is there a way to look this up, or is it just guess and test?

Is leaded, non-no-clean paste solder a thing?

I'm having trouble finding such a thing for sale, is it not made, or have I just not looked hard enough?

EDIT: I know what no-clean flux is and what it does, which is why I know that it's a lie and I don't want it. I'm perfectly happy to clean rosin off after soldering if it means I don't have to deal with that gummy bullshit.

Exciting things in the works

Sampler cart for Amiga based on the excellent Open Amiga Sampler, with significant modifications and upgrades (wider input level adjustment, tunable anti-aliasing filter, 1/4” phone input) and an all-new 3D printable case. Plugs directly into the parallel port on the back of the computer.

KiCad 10 not expanding variables in paths

I set the environment variable KICAD_USER_DIR in path configurations, but when I reference it in other path definitions, EG: ${KICAD_USER_DIR}/template, it creates a directory called `${KICAD_USER_DIR}` with the path to the template duplicated.

This worked fine in KiCad 8 & 9.

What am I doing wrong?
