Here's a follow up to my own post from last year. I started with a CMD CQD-200/T SCSI tape controller, which was actually labeled as an MTi QTS-30 tape controller. It worked as a tape controller but a /M disk controller or /TM tape + disk controller would be a lot more useful. I reverse engineered a /TM CSR decode PAL but it would still only function as a tape controller with the /T firmware I had (F200T1C6B/F200T2C6B). Eventually I found someone with a CQD-200/M and they sent me /M firmware (F20001E1/F20002E1) and I was able to successfully use my /T as a /M with the /M firmware and the /TM CSR decode PAL. The only issue I had is that it wouldn't boot from a SCSI CD-ROM drive in a PDP-11 system. Then just recently I acquired a BA123 box and was pleasantly surprised to find a CQD-200/TM inside it when I opened it up. I copied that firmware (F200Y1A8C/F200Y2A8C) on to my CQD-200/T and now it functions as a CQD-200/TM and now it will also boot from a SCSI CD-ROM drive in a PDP-11 system (I find it handy to be able to boot XXDP from CD-ROM). So anyway, if anyone has a CQD-200/T (or MTi QTS-30) or CQD-200/M and they want to turn it into a CQD-200/TM it can be done and I can provide firmware and CSR decode PAL images. -Glen On Tue, Nov 3, 2009 at 10:13 PM, Glen Slick <glen.slick at gmail.com> wrote:
