Knivd came up with a beautiful P2 module, over on the Parallax forum. Others have elaborated on the design but no sign of Knivd in a long time.

He apparently updated RIDE on his GitHub account three weeks ago:

I always intended to build a ELLO but I couldn't find a source of the VGA/PS2 connector at a sensible price once postage had been taken into consideration. In fact, I found it very difficult to source other than from Mouser IIRC - a company I've never dealt with. I had a brief attempt at laying out a new board with more common connectors but gave up as it wasn't working out. I've not touched it for ages, but I still have the PCB if anyone wants it for the cost of the postage. I would advise anyone interested to find the connector first.

Yes, I ordered that connector from Mouser back then, too. It was relatively expensive (significantly more than a standard VGA and two PS/2 connectors would have cost). It’s only worth ordering from Mouser if you exceed the magic €50 threshold - then you don’t pay shipping costs, which otherwise amount to €20 on their own. On the other hand, Mouser doesn’t charge a minimum order fee - only a mischievous person would think ill of that...  

Still, it's a pretty nice little device and a lot of fun to use! It's really annoying that the .lsl command doesn't work anymore. It was very helpful to list the internal libraries...

Unfortunately, I don't have a GitHub account - maybe someone could bring the issues I've listed to Knivd's attention?

I have an affinity for the PIC32MX170 but with the ByPIC interactive language. Such a shame that it didn't catch on.

At 40MHz and 32bit integers, performance is easily up there with the CMM2.

Hardware interrupts and a huge library of code.

If you choose to run your program within a fixed timer interrupt period (in my case, 1ms), the command prompt remains active.

Compiled C code is only seven times faster.

Thanks for the good words about the Ello. In more recent time I have moved onto other things and have not touched it for quite some time. However, my new best friend Claude thought he might take a look at the code and try to fix those reported issues and then updated the repo. Unfortunately, I wasn't able to find my board to test the fixes but he was very confident and I checked the code and it appears correct. So, here it is - R122 in the github repo. I added the compiled hex as well.
Looking at it, this version has some rudimentary support of the 8080, Z80, and 6502 CPUs on which I had started working back then, but can't remember how far I got with it.
Anyway, let me know how it performs. I will keep checking this forum from time to time again.

Thank you very much!      
I’ll give it a go as soon as possible!!!

@knivd:

Unfortunately, the new version isn't working properly:

- ELLO does not start when the SD card is inserted.
- The .lsl command still isn't working
- I can't get any of my old programs to run anymore. After typing .=, nothing happens at all...   Loading the programs seems to be working...

.n without a number no longer renders the device unusable
