🟢 New Product In Stock Now...
3 Slot Expansion Card for the Feersum MicroBeastThe first piece of hardware specifically for the Feersum MicroBeast, my new 3 Slot Expansion Card is now listed up on my website alongside all the other RC2014/RCbus peripherals I make.
https://2014.samcoupe.comPlugging into the single slot at the top of the MicroBeast this card then gives you three expansion slots for plugging in all your other compatible cards.

I haven't got time to play with this card any further, but here's what I really like about the interoperability of #rc2014 and #rcbus.
This card is designed by Jerry Frost (MG013), it's running on a board by Steve Cousins (SC126), to a interface standard by @rc2014 and with a ROM by Wayne Warthen (RomWBW).
And it bloody works.

Achievement unlocked
#Fuzix now runs on the classic 6800 CPU using the rcbus-6808 CPU card.
Took a few small compiler fixes and some other bits and pieces being finished off but with zu2's work on the 6800 code generator all now appears good. Startrek anyway

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
Hardware release very soon

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

Got my Z80 based RCBus computer built and running CP/M. I designed a small RS-232 board that is on its way from JLCPCB. Assuming it works I'll share the design files for it too. #retrocomputing #cpm #z80 #rcbus #homebrewcomputing #rc2014 @etchedpixels

More testing of #rcbus boards. Z180 Mini-ITX board powered up first time (yay). Need to do some work on the firmware and emulator next to get RomWBW driving it nicely.
TMS9995 one however has me stumped. Clock running but sitting with D0-D2 and MEMEN high, nothing indicating instruction fetches, int lines all high, ready high. More investigation needed. Need to finish the NS32K board next.
