Like last year there will be a retro devroom, the CfP is here.

I also noticed that after taking care of my LC-III, on the next one I noticed that and went back to fix it. It seems people "discovered" that just now again. 🤷‍♂️

In case you missed it, the FOSDEM RetroComputing devroom CfP is out. Deadline is December 1st. It will take place in Brussels on February 2nd.

Indeed, that's what egretrom does (it's linked to from the thread's first post and the image contains source code): thePB.pbCmd = 0x2; /* read 6805 memory */

Actually it seems I posted it on this same thread in 2023 😅 Thanks :)

When I say I'm on it… I'm on it. I spent nights digging the schematics and comparing pinouts, and producing that spreadsheet, but you didn't ask :p I also patched radare2 to fix support for 6805 disassembly so I could reverse the other dumps, but haven't finished yet. Fixing tools takes so...

It's not the only one that might work. I've been on that for 3 years :p Which is why I didn't go the simple programmer route because they all have their own variant and I didn't want to make 3 different boards. I have a prototype programmer already but the software is not yet working.

Well, it's not that old… incidentally someone prodded me into looking at it again this week-end, so…

I'm starting to have some stuff to sell… Joe told me Tindie had some issues (like, not allowing different items per order!?), anyone experienced that? I'm already behind on sysadmin for other servers, I'd rather not have to maintain my own shop…

Last changes on these, I think we can ship! Wait, I don't have a shop yet 😅 Protos from left to right, original on the right.

Nice result!

Hmm yeah, I suppose for more complex or visible parts that'd be something to try. But they you'd need to add the adhesive layer, so cut it anyway. Btw, the round ones if they are what I think they are, you can find them quite cheap already on ali.

Updated last prototype, I think it's close enough. Though sanding makes it clearer so not really better looking.

Yeah thought about molding as well but we lack the equipment here… Laser engraving works not too bad, except for the raster effect (although I want to try sanding that), and it takes time so it's not as cheap as I envisioned, but if I use the full width of the machine I can probably make it fast...

I've been modeling (if you can all drawing shapes with grey gradients in Corel Draw modeling) some feet since then, mostly for PowerBook stuff… and VAIO. Latest prototype, can you guess for which machine? (left is original, right is first version):

Last week I finished the test equipment, so I can make sure they work after soldering the chip:

The pitch is half of that… So yes it's feasible but best avoided, as it could give shortcuts.

Well I found the perfect connector in KiCad's library… then I failed to actually order one because they don't exist in 2x50 pins unkeyed 🤷‍♂️ I experimented with slicing PCI connectors (it needs 2 more pins than the actual amount on the main section…). Would work but it's finicky…And the other...

My initial idea was to make a board to support both with either connectors, but I'm wondering if it might not be too large, probably simpler to do separate boards…

That's great, now if only you didn't have to sacrifice a Mac for that…
