Bally's Low-Cost UV-1 Zgrass Graphics System


The BALLY UV-1 Zgrass System is:


The most advanced graphics system with a user-oriented language. Ten years in 
development, it is the microcomputer most suited to producing visuals on a 
television set.

The only computer system available with the proven ruggedness and reliability 
of Bally's commercial video arcade games. Zgrass has the same card rack, power 
supplies, RGB video monitor and memories.

Based on the Bally Arcade chip set, an LSI graphics implementation with 
hardware pixel shift, exclusive OR, OR, and direct screen writes, fully 
software supported. The resolution is 320x204 with two bits/pixel which 
automatically map into four user-specified colors chosen from a set of 256 
colors. Ideal for Computer-Assisted Instruction (CAI), comes with its own 
tested and proven self-teaching package.

Usable with intelligent floppy disks, audiotape, printers, and other computers 
over a RS-232 serial line at up to 19.2K baud for file storage and 
communications. Provision for user implementation of custom drivers.

Excellent for television applications: output in both RGB and legal, recordable 
NTSC video. More software than in any available video titler!


The Bally UV-1 Hardware Comes With:


64K bytes of memory (16K EPROM, 48K RAM).

Floating point processor for extra speed.
