That's a bit worrying...I'll have to get something working on the Falcon IDE first & then I might have something to compare against. Any details on the IDE to CF adapters you've found to exhibit this behaviour? So, I just re-tested the adapters and this one works fine: CF1-working.jpg CF1-worki...

I have some 44 pin IDE to CF card adapters that work in my H4/H4 but not in my Falcon. I think there are different version adapters around.

Hi @kodak80 I let some of your ISA PCB v1.3 be made in China for my ATX Board. I am struggling a bit with sourcing the SMD battery holder for the RTC Do you evtl have a source or a vendor/ part number for a suitable component? All I could find locally here in Germany are much wider than the 20mm on...

Okay, I have the mATX ST MIDI in working now with original pinout. Using an alternate optocoupler CNY17F-3 chip borrowed from one of my H4 boards.


MIDImaze 2 connects and works

Hi, The original PinOut is absolutely Ok for the 4N33, but the chip itself seems to be not suitable - too slow. I have been successful with a CNY17F (available via e.g. eBay) using the original pinout At least using a Diag Card and a MIDI Loopback cable this gives me a „pass“ (I do not own any MIDI...

Yes, 8 bit ISA slot is what is in the EtherNEC adapter. I have built up 3 x 8 bit network cards from this one: https://github.com/skiselev/isa8_eth I need to find a way to program the 93C46 - 1 Kbit EEPROM as the network cards do not seem to work without the chip being programmed. A program is prov...

Okay, my MIDI Opto fix adapter boards arrived today that swap pins 4 and 5 on the opto-isolator IC on the mATX ST board. If anything, the fix adapter makes things worse as MidiMaze cannot communicate at all over the MIDI cables with the fix in place. Clearly there is something else wrong with the MI...

Version 1.2 is now tested and RTC, cartridge port and internal 40 pin header work. EtherNEC is now also tested and works when connected to the cartridge adapter internal header.

I tested the v1.1 of my ISA cart adapter yesterday and it works which is great considering I had to move from Eagle to KiCad for v1.1 due to the size of the PCB. It was too big when I moved the cartridge port outside the ATX casing and Eagle (free version) would not allow the size board needed. I ha...
