Sometimes I make retro inspired computery things. Very occassionally they work. 
I sometimes 3d print stuff too.

We did get the X-rays done, but it was utter chaos when we went to collect her.

Any dog in serious pain would have been absolutely terrified by what was going on, not just in the waiting area, but also back of house

So incredibly unprofessional

It’s mildly* annoying when your dog needs urgent medical care, and to be told getting X-rays done might be an issue because of a fucking Halloween party in the waiting area

* = very fucking annoying. #notimpressed

We gave 3player #Sowee a test run last night. It might be even more brutal than 3 player on a standard board!

Next step is to print another set, the edges fit together with pin and hole, so a 6 player board, with 3 players, and an unused start/home between each is the idea

I took the initial #Sowee design by @PaulaMaddox and recreated it in #Freecad. Getting it right was hard work, as it’s resizeable (mostly), but I think it came out quite well

In case it’s not obvious, it’s a 3 player version of Sorry, but could be extended for as many players as you could practically fit around the table.

Every time I think I'm getting somewhere with #Freecad, it gives me a huge sucker punch, and reminds me that I really haven't got a clue how it works.

I am so close to just giving up on it.

Spent this weekend working on the #PC6502, this is my stack up, consisting of the CPU board on the bottom, fitted with a #16bit 65C816 running at 12.5MHz, a Compact Flash storage board in the middle, and a 65C22 VIA board on top

Various bodge wires, CPLD tweaks, and testing with various BASIC programs, have this running nice and stable, even if I overclock to about 17.5MHz

First attempt at the CPLD for the #PC6502 compact flash storage board, and it only flipping works. I'm doing it all from BASIC again, so it's slow, but it reads and writes sectors successfully.

I kinda want to mess around with the memory map to maximise the amount of RAM, and use a minimal ROM to boot the system from CF.

About to start on the CPLD code for the #PC6502 #CompactFlash board. If it works, then I'll adapt my "monitor" code to read sectors from a CF card

Should be interesting.

Here is the full stack.
Top to bottom we have;
* Apple II slot card
* VIA card
* Dual SPI card
* Compact Flash Storage card
* OPL3 and Speech card
* 6502 CPU, RAM, ROM, console card
* power supply (USB upto 15W or DC barrel upto 50W)

Interesting... Having first programmed in BASIC on a #ZXSpectrum back in the 80's, I just assumed that line numbering always topped out at 9999

On the OSI/MS BASIC in the #PC6502, the highest valid line number is 63999
