jbdigriz Posted August 20, 2021 Share Posted August 20, 2021 Bitsavers has turned up a board set for what appears to be a BS300 of some kind on Ebay and purchased it for detailed photos and ROM dumping. The system board differs from the one shown in the BS300 paper currently on bitsavers in that it does not have the ECC chip shown there. He's also needing a backup dump of the terminal board ROMs since one of the ones he's getting has a missing cap and may be corrupt. If anyone has BS300 software, though, particularly DX10 or DNOS sysgen'ed for the BS300, which uses the QBIC interface for the WD500 and 800 drives, or BS300/300A documentation, please post here and/or submit to bitsavers. There is a definite possiblity of a BS300 MAME driver in the offing.
