From: technoid(a)cheta.net <technoid(a)cheta.net> The options installed in the machine are listed at: http://users.leading.net/~dogas/classiccmp/cosmac/cosmac.htm It's an 1802 microprocessor based system (of course) with 60K of ram, 15 slot (Microboard buss) "card nest", rom( ut21 utilities/monitor), parallel&serial i/o interfaces, integrated ascii keyboard and crt, extertnal dual 8" floppies (CDP18S801), and ports that tightly link in an external Micromonitor (CDP18S030) microprocessor ICE unit. CDOS, The disk based operating system has (I'm looking for) programs for full screen editing program and various levels of interpreters/compilers for Basic, Assembler, Pascal, etc... I found a source for the PLM compiler and MOPS (the Micromonitor Operating System) so the machine won't be completlely without software soon and I can already now hand assemble stuff and poke it in through the the ut21 monitor ;) - Mike: dogas(a)leading.net
