TI Workshop Wiesbaden RS-232C Serial Interface

New page

== RS-232 Serial Interface ==

This card provides the TI-99/4A with two RS-232C serial ports (also known as V24 ports in Europe) and a single parallel port. The card has a set of internal wire straps that can be changed to change the address of the card and allow a second RS-232 card to be inserted into the PEB. Ports on the card with the modified address are accessed as RS-232/3, RS-232/4, and PIO/2. The DSR on this card can be modified to make it compatible with the [[TI-99/8]].

The interface card from TIW contained a parallel interface for attaching a Centronics printer, and two serial ports. In addition, it had circuitry for single-step debugging.

The card was designed and built by three people:

* Michael Becker from the system 99 user-group (SNUG) did the hardware-design and the PAL-programming
* Horst Wiese from TIW did the layout and
* Juergen Stelter from TIW had assembled them all.

It is a clone of the Corcomp card, but with a PAL for decoding and some buffer chip to save the rare and expensive TMS9901 PIO-chip, which is almost always blown in defective CC-cards. The DSR is still the same as for the CC.
It is a very rare item; possibly because of quality problems with the pcb only a few were built.
