During this time period two standards organizations JEIDA and PCMCIA were working on the standardization of memory IC cards These cards were designed as strictly non volatile silicon storage JEIDA was the first to propose the 68 pin connector standard for memory cards In 1989 PCMCIA adopted the JEIDA 68 pin standard and worked with JEIDA on further developments As the notebook market grew the need for a standard I O bus was seen The PCMCIA groups saw an opportunity to meet this need with an expanded version of the 68 pin interface Further development occurred and within one year release 2 0 of the standard was completed Release 2 0 was a major update to Release 1 0 and included full hardware support for I O devices Release 2 0 coincided with JEIDA s 4 1 release and is identical The PC ACB MP adapter provides your portable PC with a single channel multi protocol serial interface utilizing the Zilog Z85233 ESCC which is suitable for the most popular communication protocols including HDLC SDLC X 25 Bi Sync Mono Sync and asynchronous The PC ACB MP utilizes the Sipex 505 multi protocol electrical interface chip that allows the PC ACB MP to be compliant with EIA TIA 530 530A EIA TIA 232E EIA TIA 485 and ITU V 35 What s Included The PC ACB MP is shipped with the following items If any of these items are missing or damaged contact the supplier PC ACB MP PCMCIA Serial Interface Adapter DB 25 cable assembly Loopback Pl
