@djsundog what all is in this box?
@craigmaloney a 16KB ROM with an upgraded version of BASIC and 128KB of SRAM
@craigmaloney imagine slotting a new 16gb ssd with os upgrades into an old laptop and getting bumped from 4gb of ram to 128gb in the process for half the base system price
@djsundog oh I know. I had a mc-10 for a bit before I donated it to the library so I know how dreadfully underpowered it was. Does it give it compatibility with a proper Coco?
@craigmaloney not quite but close - it's still saddled with a 6803 and a sub-megaHertz clock, but the basic implementation has almost full coverage of its bigger siblings
That's a pretty big jump in capacity for an MC-10!
I didn't think the expansion port could accommodate more than 16K much less that the machine was capable of bank switching to address more than 64K...quite an achievement considering the limited expandability of todays small computer devices!
@msh the rom in the cartridge handles the bank switching - it's a neat add on after thirty years :)
@djsundog people got creative when confronted with limitations.
A long time ago I was thinking of how to make a bank-switching Colecovision cartridge...that had NVRAM for saving stuff like high scores to...for a cartridge port that was designed for ROM only...
The idea was that you'd have the CPU read a specific address to enable "NVRAM write" mode then the next read would be the NVRAM "register number" plus write value as the address
@djsundog Whoa, awesome!
