In case anyone is interested, I sent Al Kossow the (PDF) manuals for the Qbus Matrox QRGB-Alpha and QRGB-Graph boards. He did not respond to or acknowledge my e-mail. In addition, the PDF manuals are still not available at bitsavers. Al, if you are reading this, did you discard my e-mail? If you are interested, I can send the e-mail again. I have other manuals as well. If anyone needs these manuals immediately, I can e-mail them to you. They are 13 MB. If you can not accept an e-mail that size, I can break the e-mail into two parts. Evidently, Glen Herrmannsfeldt scanned these manuals. He also sent them to me. The e-mail from Glen with the manuals arrived after Lou Ernst mentioned that Glen probably had the manuals, but had not scanned them at the time (a few years) ago. After I reminded Glen, he sent to to me. THANK YOU to both Lou and Glen. Sincerely yours, Jerome Fine
