Austin, TX 78760
Owner(s): Jerry Chamkis

AERCO made disk drive systems and other accessories for the TS 1000 and TS 2068 computers.

Jerry Chamkis, owner of AERCO, now makes microphone pre-amps and a very unique musical instrument called the Kosmophone.

He studied physics at the University of California, Santa Barbara, but disillusioned by the emphasis on military applications, he left and became chief engineer at a radio station in Houston, Texas. In 1975, he formed AERCO (Acme Electric Robot Company), where he initially produced peripheral devices and memory expansions for small computers and then moved on to computer-controlled hot wire cutting systems, broadcast equipment, and microphone preamplifiers. Since about 2000 he has concentrated on various art projects such as the Kosmophone.

TS 1000
High speed, all Z80 codes.
TS 1000
This floppy disk system for the TS2068 can control one to four 3″ to 8″ drives. Loads programs at 250k bit/sec. 64K of on-board RAM (mapped to the DOCK bank) can be used as system memory or to run CP/M. RGB output for monitor connection.
TS 2068
Supports 1-4 drives of any size, single/double density. Software driver in EPROM.
TS 1000

TS 2068
Converts the ZX bus to STD Bus. Allows for use of peripheral interface cards from numerous manufacturers. On-board memory expansion option. Memory-mapped ports.
TS 1000
Interface 2 small stepper motors (1 Amp max.) to a standard Centronics printer interface and make fully coordinated 2-axis moves. Provides 4 limit-switch inputs and all the software you need to completely and accurately control a 2-axis machine. This is available for the 1000/1500 and the 2068 machines, but the 2068 is the recommended choice
TS 1000 TS 2068
Facilitates preparation of documents and handles any size printer. Provides blinking cursor, keyboard features, insert/delete, tab, etc. 16K.
