Re: [cosmacelf] Re: Membership Card Owners
- I think that "microdrives" were about the size of a double-thick
flash memory card... something like you'd use in a digital camera.
If the drive is 2" to 2 1/2" wide, it's like a laptop disk drive.
The microdrives are *much* smaller.

4k ROM. The monitor is the part that actually does the memory sizing. It
needs RAM for its register save/restore and breakpoints. It starts
testing high, and progresses downward until it finds a byte that it
can't change (the ROM). Unfortunately, this test fails when the monitor
and BASIC are in RAM.
I'll get to it. Just too many other things to do...
