Hi guys, My LPFK reverse engineering attempts have drawn a blank -- does anyone happen to have a copy of the PC drivers for this thing? IBM part numbers were 39F8224 and 39F8225, for 3.5" and 5.25" format respectively. These discs contained diagnostic software and drivers used to connect the LPFK to a PS/2, PC-XT or PC-AT. Rumour has it there was also a connection pack, #4025, which consisted of the diagnostic disc, serial cable and power supply. There's also a document referenced in the RS/6000 Graphics Handbook -- "IBM 6094-020 LPFK Options Instructions, GA23-2403". Does anyone have a copy of this, and is there any useful information in it? At this point, I don't think there's anything else I can really do without either some software that can talk to the LPFK (and maybe a disassembler...), or some actual protocol documentation. Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
