HS-1 and Z-99
In sync-magazine march/april 1984 page 81 I have found this small advertisement
about "High speed interface HS-1". Does anyone know more about it????|
The interface connects a TS1000 with 2k-RAM in slow-mode with another ZX81, TS1000 or TS1500 which may run in FAST-mode. The first TS1000 works as display-computer.
The HS1 was sold as a kit for US$78 or soldered for US$ 98, the cable for $19.
Do you have an idea how the two busses are connected?
If you have any information, please email
