- Hard Drive image option for the Premium+
Check out MAXIM's - DS12887+ these fit into the latter MB1248, Premium and 256TC Microbee's with very little changes required. These are available new from various sources, just be aware of none new ones (ebay) as the internal lithium batteries maybe depleted, been caught there, however even then they can be repaired using an external battery for the adventurous.
Even reduces the original parts required as both the battery and the clock are on-chip. Just ensure you enable MOTOROLA mode not INTEL mode.
Works really well with the PJB Enhanced BIOS.
A little more challenging for the early Microbee that didn't have RTC provision on the mainboard, however not too hard to do an off board option with flying lead type connection in the original RTC fashion, PM me if you're interested as I have a couple of boards left that fit vertically to the left of the top cover support of the Microbee case.
I agree with the Hard Drive idea, the SD card has plenty of room on it and being able to emulate four partitions of a hard drive Microbee would make the system a lot more usable, making most programs available without the hassle of swapping Floppy images in and out.
Rather than the complexity of SD Wifi, just having the ethernet port functional to transfer files to and from another PC would help with file transfers.
