The HP 95LX (MS-DOS 3.3 in ROM) came out slightly after the Poqet, and it also does not have a fully PCMCIA 1.0 compatable card slot. The HP 100LX (MS-DOS 5.0 in ROM), which came out in 1993, has does have a fully compatable slot, PCMCIA Revision 2.0, IIRC. The PCMCIA (Personal Computer Memory Card Industry Association) was formed in June of 1989. -----Original Message----- From: Fred Cisin [mailto:cisin@xenosoft.com] Sent: Thursday, September 25, 2003 7:39 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Old DOS on topic yet?

Does anybody know offhand exactly when the PCMCIA standard came about? PCMCIA = "People Can't memorize Computer Industry Acronyms" The Toshiba 1100, and the Atari Portfolio wer out about that time, and like the Poqet, they had versions of DOS in ROM. (The Portfolio was a wannabe, Toshiba and Poqet were MS-DOS)
