Need more CPU power, your #rc2014 mini-cray not pulling its weight, jealous of people with multiple CPU cores. All that can be in the past. The new ECP180 allows you to put up to 8 Z180 processors to work at once on your system (16 with a small PCB mod). Each unit as a shared memory interface and 512K of local SRAM as well as local serial and SPI/SD interfaces via the CSIO in case you want to build a classic MP/M & CP/M multiuser box S100 style
I wonder if there’s a way to make an @emf@badge Tildagon hexpansion to bridge to @rc2014. It’s ridiculous, but it’s stuck in my head. #emfcamp#rc2014#badgelife
Amazed at how many subtle incompatibilities there are between the (pirated??) Microsoft 8K BASIC the UK101 ran and the Microsoft BASIC-80 CP/M version - eg PRINTD$ without a space between the T and the D$ is not OK in BASIC-80!
OK - I can now update the playing area successfully, but it's too slow to play if the whole playing area is updated every time a move is made. Time to improve the movement algorithm - should be straightforward enough I think.
Note to self: you'd make faster progress if you don't stop to refactor the code every 10 minutes!
But I do have the swamp and wood scenes working correctly now. I need to work on the castles next and I've noticed glitches on scene exit and status area formatting.
And yet more refactoring is required, as well as speeding up the entry to new scenes ... this is taking longer to port than I'd estimated - nothing changes !! 😂
There's a glitch in special finds to fix, plus yet more refactoring and speeding up scene changes required ... but the game is now playable on an #RC2014 or #RC2040.
Also on the to-do list - looking at moving beyond 7 bit ASCII codes for display when running on the PicoTerm VT emulator!
Managed to route the #rcbus Zilog Super8 card today and the 80C196KB CPU card. Some compromises needed on the 801C96 in particular to get all the I/O on the card. Both a bit bigger than standard #rc2014 size but who cares. In fact it may even be helpful as some of the connectors are quite tall (PS/2 especially).
The super8 also hopefully has 8bit DMA driven digital audio because one of the 8bit ports can be driven via DMA and an external ack, and there is a timer output pin
So close! Just one failing test on the zexdoc #Z80 instruction exerciser left to track down (and another couple on zexall that I don't think I need to bother too much with at the moment).
Made an enclosure for my rc2014 computer (sc-114) from polystyrene and acrylic glass sheets. There are two mini-USB jacks for serial connections on the backside, both attached to FTDI adapters. Only drawback: you have to open the case to reset the system.
I am mostly using this computer to test my T3X/0 compiler and other Z80 programs on a real machine. #retrocomputing, #cpm, #rc2014
sending hex files to my #rc2014 by pasting them into ed with a serial paste delay of 2 ms (the baud rate is too high for xmodem to work and i dont have the jumpers soldered to reduce the baud rate atm)
it would literally be faster to take the CF card out and copy the file that way but where would the fun be in that?
Slight update for 2024 - my SID Sound Chip Interface for the #SAMCoupe
Added a colour coded power LED to show the status of the SID power supply circuitry and improved board layout to clearly identify the type of SID chip it has been built for, rather than having a label attached.
Also supports modern SID replacements such as the SwinSID and ARMSID.
Trying to build the RC2014 zed kit. I got really confused about how to connect the partially single-row, partially double-row bus pin headers. No matter how I tried, combining single- and double row pin strips didn't work. And I couldn't find a decent description. Only this picture gives a hint: use a double row strip and pull out the unused pins....

I finally got my #rc2014 into a proper case. In the process, I've learned that Santa needs to bring me a drill press for Christmas so I can drill straight lines of holes!
Thanks @rc2014 for the endless possibilities and the hours of nostalgia.
