Here's the roundup of our posts for June. Comments welcome on this thread! Check the original posts on gplus for comments too. (See also our previous roundups and our profile page - or look here.)

2017-06-02 - Ben Chong has made a nice little 6502 CPU card for the RC2014 retrocomputer, which is a modern 8-slot backplane-based computer kit, originally for Z80.



2017-06-09 - the wonderful expandable Acorn Electron! A cost-reduced BBC Micro, it has an edge connector at the back - with some solid bolt holes, so no wobbly RAM pack here - allowing for a surprising amount of expansion.



2017-06-16 - a treasure trove of materials from Dennis Jarvis, ex-Commodore, working on the 1581 and the famous C65 - seen here in prototype form, on a wooden base.



2017-06-23 - an Apple II emulator in Python, by James Tauber - from 2013, and originally conceived in 2001.

Just want to chime in that these are great summary post of such things, but the images have never worked for me.

Hmm. Is that on a desktop (which browser?) or mobile (which platform?)

I've just checked in an incognito window on Chrome and they are fine. Hmm, but checking in IE11 on browserling.com the images are little black boxes.

Are you able to click through and view the posts OK?

For me, (Firefox, Win7, Desktop) the images appear only as a link to the image, not as actual inlined pictures.

Also, I maintain KiCad libraries of Retro Computing and Arduino components you might find useful.

Sorry about that, it seems I was always choosing image links which were a bit special. I've fixed the ones on this page, I think.

Ah yes, I had thought that where it said image, it was just supposed to be a link, because I wasn't getting an image either. I use FF under Ubuntu 10.04 (Linux). Thanks for fixing them so they show.

What's an additional VIA among friends, anyhow?

yea, a lot of the times this happens, it works okay for the poster because the links are tied to them, or because they're logged in to the picture site, or something like that. In the end it becomes "works for me, must be you" because they do, indeed, work for the poster.

But thanks for fixing them.

I thought I'd defended against it being just me - but in this case it wasn't that, it was an image format supported only by Chrome.

Just curious, what format was that?

It was WebP.

Ah. Hadn't heard of that one.
