For a possible 7800 game test down the road, I am looking
for someone with all of the following:
- 7800
- eprom burner
- 7800 cartridge which accepts a 16K or 32K eprom

Thanks.

I'm sure nobody's really interested but here's a quick
status report of my "factor Z" attempt...
Several weeks ago I started at sqroot(Z) and I am working
backwards checking for a remainder.
Z=

As you can see, I haven't made much of a dent but this is
running in the background so no biggie.
And FWIW here's my bruteforce code using the Miracl library...
val = getdig(NEWZ,0);
loop: copy(Z,TEMP1); // TEMP1 = Z
divide(TEMP1,NEWZ,NEWZ); // TEMP1 = Z %
NEWZ
if ( size(TEMP1) )
{
val -= 2;
if (val<0) // skip 15
{
val = 13;
subtract(NEWZ,FOUR,NEWZ); // NEWZ = NEWZ - 4
}
else if (val==5) // skip 5
{
val = 3;
goto ahead;
}
else
{
ahead: putdig(val,NEWZ,0);
}
goto loop;
}
