C64/C128 Hardware

In this page, which I have put an 1541 memory expansion document, I presented some useful hardware projects and documentation about construction of add/ons for C64/C128.

Tower-C64 documents

Peripherals

Upgrading 1541's memory to 32K : With this old document its possible to use Maverick's additional features.

Modification of a PC Mouse for C64 : This text describes how to adapt PC mice to be used with C64/C128 computers. Cheap approach to use a mouse with GEOS. Related mouse test programs, and an GEOS input driver for PC-mouse are available also.

RS-232 Interfaces

Different RS232C serial port schematics are located here. The main concern is the simple nature of them. There will be some multi-port schematics soon. I'll also include the simplyfied and improved Datapump schematics either.

Simplest 2400bps interface : This interface uses only one IC and very few wirings. You can build it in minutes. It is the cheapest method I guess.

2400bps interface with rts/cts : Addition of some wires to above interface make it capable of rts/cts flow control.

9600bps interface with rts/cts : Using the 9600bps hack of Daniel Dallman, and modifying presented simple interfaces, this high throughput interface can be constructed. It still use one easy-to-find IC, but wirings are a little bit confusing.

C64 icin rts/cts'li 9600bps user port arabirimi : (Turkish version of the above) Daniel Dallman'in yuksek hiz hilesini kullanarak C64 ile 9600bps'e C128 ile de 19200 cikabilir. Ucuz ve kolay bulunur bir entegre kullandigi icin yapimi zor degil.

Building Null-Modem Cables : Wiring schemes for different null-modem cables are documented here. This cables are used to transfer data between any two computers, such as C64-C64, C64-PC, PC-Amiga, C64-Amiga, Mac-Amiga,... any combination is Ok.
