Size: 625 ($271) bytes
Screenshots
Features
- Detects Apple ][, ][+, //e, //e+, //c, //c+
- Pretty-print model instead of generic
II
(bloats the code slightly but worth it.)
- Pretty-print model instead of generic
- Detects 48K/64K/128K
- System information in all uppercase (for Apple ][ without lowercase)
- Cleaned up fugly logo by Albert Lai
- Logo is now 70 chars wide
- Logo is bit packed 2 bits/char; expands 70 chars * 4 px = 280 px
- Logo takes up 70*12*2/8 = 210 bytes compared to 79*12 = 948 bytes
- X is now symmetrical
- Fixed L,i,n kerning
- Fixed x Penguin kerning
- Fixed L to fit
- Chopped off 2 columns of penguin to fit 70 chars

See: ascii2hgr2bit.c for packing ASCII to 2 bits/char. NOTE: PackedLen isn't needed if full 40 bytes HGR width is unpacked to.
Inspired from non-optimized version. Size: 1,573 ($625) bytes
Note: Lowercase doesn't display properly on ][.
