Having failed to get my first version of the C011 #PC104 #transputer adapter to work, I've gone for a simpler approach.
This has just the Inmos C011, 5MHz oscillator, decoding logic (CPLD/74*245) and of course some LEDs.
I've added more this time which I hope will give me of an idea when something is working or not.
I've also brought in all 20 bits of the ISA address bus to the CPLD (not that I think I'll need it but just in case).
I've also used DIP chips in case I need change the speed. -
NotLadp and NotSys are two addresses (0x150 and 0x160) and are asserted when the address matches.
PCLK is the ISA bus clock (14.3MHz on my #PC104 PC).My logic here is that this is a 3 stage ripply counter.
When either address is invalid, the riple counter is reset (.ar = asynchronous reset).
So when an address is valid the IOCHRDY signal will be LOW, i.e. force a wait state. -
Wohooo!!!
My #Transputer #pc104 adapter lives!!!
Turns out the CUPL code has two pins inverted (active low) that should not be inverted. -
Same sequence of events on my pc104 PC controller by QBasic, I don’t get a response from the TRAM for first read :(
So something isn’t right with the PC timing or the CPLD.

The #PC104 version of #PicoGUS works and is sounding just amazing!!
Thank you to @polpo for his work and efforts that made porting his ISA card to PC104 such a doddle

Are there #monitors #displays our there that do this (see image) nicely i.e. have mounts and/or compartments with power for one or more #miniPC or #raspberrypi pi #formfactor #singleboardcomputers #SBC on rear of #monitor and feed #ports to a built-in / attachable #hub #dock #dockingstation #KVMswitch ?

I’m getting nowhere with my #PC104 computer, basically it’s too fast for my needs (celeron at 1Ghz with 1Gb ram).
Does anyone have something sub 300Mhz in pc104 they would like to swap? -
#PC104 #Transputer woes...
It seems I can write a value to the TRAM (a T425 based one) but when I try to read it back I get rubbish :(This is my writing 0xAA55AA55 to address 0x8000FF00 (this is a valid address)
but when I read it back, I just get 0x10101010

Well the #PC104 #Tranputet link board is assembled. And it sort of works.
I can write to the link controller (0x150 base address) and I can send and read data through the link ports for the transputer. But (you knew it was coming right?) when I try and read the status from the control logic I get the wrong values, even though I can reset the TRAM and set the analyse signal.
So I’m a bit baffled. -
Quick fit check of the big parts, everything fits.
I got lucky with one SMD part that if it had been slightly higher on the board it would have clashed with a part on the underside of the TRAM but I did have high 8pin headers just in case.

Hooked up a display to my #PC104 computer and did a quick qbasic program and yup it works.
I need to do proper address decoding next.
That’s what the CPLD is for. -
And finally the dual #Transputer TRAM #PC104 board is done
Going to let them sit for a couple of days in my head, and then order PCBs.
-
And of course, my #PC104 #Transputer link card had to be updated :)
-
A while back I bought a couple of #pc104 power supplies, one is just pc104+ and one is pci104.
So I figured what the heck and went for the flashy one first and yup it lights up, connecting it to my pc104 computer it does indeed boot. But I did need to remove the previous battery clip and put in a lower profile one.
The flashy one is rated for 188W which is insanity in this form factor. But it will be handy when I start adding cards and transputers to the stack.

I designed a PC104+ breakout board.
I'll be using this for various experiments and tests, almost certain around transputers.

Oh, here is a better picture of my pc104+ computer. Kinda cute eh?
Depending on how well my pc104gus card works I may do more cards. I have ideas.

@furan
I think I read about PC104 in popular #electronics like 30 years ago. And in the last 20 years, I read about #arduino and SBCs. what made you decide to use #PC104 ? -

And yes, #ISA also includes PC/104 (and I've also compiled support for that in as well) so I'd love to see people try this with anything they got at hand.
I wished I had @rasteri 's #WeeCee to test OS/1337 on....

@polpo the only feature one may miss is #SoundBlaster 16 / #GameBlaster compatibility and maybe a #PC104 version and a header for a #Gameport...
Then it would be a perfect replacement for the discontinued #CS4237B that @rasteri used on the #Wee86 & #WeeCee...

@ActionRetro C3's are hard to come by...
You may be able to find some #C7-based #industrial and #embedded boards, similar to the SBCs that @rasteri used for the #Wee86 (A #PC104-based Retro Mini PC) and #WeeCee (same concept but smaller and eith a more modern CPU) but those will be frightingly expensive.
Not shure how well #VIA made cross-generation compatibility but consider getting a #ViaNano and see if you can choke it down in the UEFI/BIOS to match C3 performance...

@flyingsaceur @polpo *nodds in agreement*
Maybe @rasteri and @foone would be interested in taking a closer look at it.
Considering they did somewhat work on the #wee86 / #WeeCee's sound solution based off #PC104 / #ISA that could be in the realm of possibilities, tho both Wee86 & WeeCee do have an RTC and only need a battery hooked up to the correct pins to just work out of the box...

@suprjami thanks to @polpo for developing the #PicoGUS because that solves a big issue I see with the #Wee86 & #WeeCee that @rasteri made:
Finding a still-in-production #ISA #Soundcard, because the #CS4237B is out of production amd whilst it's not looking as if the stocks are going to dry up soon, I think avoiding out-op-production parts as much as possible is the most sustainable way to keep it available.
OFC one could also redesign it for #PC104 too...
