OLD HP 7220C ROM

Hi! I'm looking for HP 7220 ROM chips. There was a kit available from HP, but now it's so old they don't even know what is it. It converts the HP pen plotter model 7221C to a 7220C. The difference is that the 7221C is not an HPGL plotter and the 7220 is. The 7221C is a "weird compacted binary" language plotter. If any of you have information about this old language, have it forwarded to me. I would be glad to even write the converter program. Thanks a million. -- ================================================== =============== "Never play leapfrog !

I think on eof th eways to do it would be to read ROM content and write it on EPROM. I wrote the conversion program some time ago, but ROM change is a better solution Thanks, Bojan |
