Project is far from dead. I've been thinking and planning. I haven't been entirely happy with the current STaceX as it doesn't allow for serious upgrades due to space restrictions and the bus extension. That's why I haven't bothered with getting the Magnum ST to work.
Major pitfall is the DC-DC converter. It's huge, and almost unnecessary. Many don't realize that you can actually toss the DC-DC away and power the STacy by feeding power to the floppy power connector. However, this would require the use of an external monitor as the LCD is deprived of the -20V bias supply and the EL-backlight of 85V AC @ 590Hz. So all that bulk just for the LCD? There has got to be a better way.
Darklord and AlanH are pioneers with experimenting on the STacy. AlanH showed us the trick of powering the STacy with just the floppy power cable. Darklord went as far as anyone could with trying to adapt another, much more modern DC-DC converter we love or hate, the PicoPSU. One of the two obstacles was overcome with Darklord finding a separate inverter for the EL-backlight. That remains the best alternative so far. The -20V source sadly has been elusive.
I already mentioned the MAX629 in my previous post just above. I'm no engineer. I made my first PCB exactly a year ago. But I did find Maxim's datasheet for an evaluation board for said IC. Layout and all and for -20V. See here: https://datasheets.maximintegrated.com/ ... 9EVKIT.pdf
. Seems trivial enough to do.
So would open all kinds of possibilities. Here's what I've been thinking of:
It's crude. I might have overlooked something, but physically it should fit.
So, lot's of space now. So here's where I'm gonna need help. Considering how far I've come in a year, I'm sure I could cook up something really cool in a few years time. Right now it's just basic stuff.
If there could be some collab to get alt-ram, flash-TOS, IDE, and a booster in there, that would be sweet. I can do all those individually but to get them working together on a single board...yeah...not there yet.
Otherwise it's plan B:
