Really? A SD card is a few dollars.
- jjoonathan 8y agoReverse engineering the 30 year old CNC and making a proprietary-SRAM-card emulator probably costs several hundred thousand (consulting overhead, a few engineer months of effort, downtime risk). It would likely be cheaper to simply replace the machine. A "hard drive unit" probably refers to a contemporary piece of kit that can be purchased new-old-stock for several thousand. Or someone is selling a $30 kit on eBay that nobody has thought to look for. Hard to tell, but one thing is certain: the cost of an SD card wouldn't even cause a rounding error in this equation.
- rasz 8y agoI can do it for $1K by overcharging you by x3. For starters SRAM is not proprietary :), and the reason we used to use SRAM for settings storage was always the price of durable component.
- jjoonathan 8y agoSure, just pop it open, read the SRAM engraving, RTFM, maybe probe around a bit, whack together an arduino sketch, and wire up some glue circuitry. Now why didn't I think of that?
