I just posted a few new things on http://nonmaskable.com: - schematics for the Series I/II CMI-01 and CMI-01A voice boards - schematic for the obscure Q050 Dual TVT board (I think this was a QASAR artifact, anyone got one?) Joe

A Q050! I have a few. This card pre-dated the bit map graphics cards and could display 80x25 character cells. They were never a end user board for users of the CMI and early MFX systems but were extensively used by R&D for high speed debugging.

Hi Steve, Thanks for the feedback on the Q050. Was it supported by both QDOS and OS9? By any chance, did you work on the Series IIL? From the Series II(x) service manual, I would guess that it used the Q077 with a Western Digital 1002 to interface with an MFM drive. I'd like to know if some versions of released CMI software were aware of that configuration. Specifically, could the CMI boot QDOS and the CMI software from the HD, and what happened to the notion of the "LEFT" and "RIGHT" drives in that case? I have a IIx (kind of a strange one, it was Herbie Hancock's) and 2.5 Series III machines (1 working Rev6, 1 working Rev9, and 1 basket case Rev6). All great machines! Also, I think you know another friend of mine, Joe Sleator. He's cobbling together a IIx now. Best, Joe --- In Fairlight-CMI@yahoogroups.com, "Steve Rance" <steve@...> wrote: > > A Q050!

Was it supported by both QDOS and OS9? Yes, the TVT card (as we called it) was mapped into processor 1's address space. With the jumpers in the default position the 1st screen was mapped in at 0xD000 and the 2nd screen was mapped at 0xD800. It's been 15-20 years, so those addresses may be wrong. did you work on the Series IIL? Did you mean the Series IIIL - (3L) - I can't recall a Series 2 with the "L" modifier. But yes, I worked on all version of the CMI and ultimately MFX (and the start of CC-1) until late 2006 Specifically, could the CMI boot QDOS and the CMI software from the HD, and what happened to the notion of the "LEFT" and "RIGHT" drives in that case? As far as I remember, with only one floppy in the system and a hard disk controller, the operating system (QDOS or CMI DOS) would boot from the floppy first, if a hard disk controller was present half way thru the boot up it would swap over to the hard drive and boot the remainder of the OS from the hard disk. There was not a way to boot directly from the hard disk. Once the system had booted, the floppy drive was then assigned the "data" drive or drive 1. Then came along OS9, this was a totally different beast and new Q077 and Q777 ROMS could boot to the hard disk directly. Joe Sleator Sounds familier, but I cant put a face to the name. <http://www.fairlightus.com/> SteveRance

Do you remember which version(s) of CMI DOS could recognize and use the HD? Did it do so just by noticing that an HD driver ROM had loaded? I see in a disassembly of the boot ROM how it scans the peripheral registers looking for valid STATUS registers, and loading the driver ROMs into RAM when it finds one. So, I guess it could just decide to always use the HD as the data drive if it sees an HD driver was loaded. Was that IIIL configuration based on the Q077, or did it also use the Q777? I see in that video that the machine (which looks like a II-class machine) has a streamer tape as well as the HD. When CMI DOS used the HD for the data drive, was it just like 1 big floppy? (No directories, etc.) > Then came along OS9, this was a totally different beast and new Q077 and > Q777 ROMS could boot to the hard disk directly. In the video, it looks like he booted from a floppy. Thanks! Joe

Worked on Cue-List and MFX1 console. Anyway, one IIx is working well. Do you know of any FCNs for IIx that brought Rev2 CMI-01As up to Rev3/4? I'm reverse engineering one now. It's going quite well. Built a daughter card to hold the SSM2045. Fewer parts than the CEM3320 based one. Quentin's re-do was nicely modular in that regard.
