I just reviewed your committed skeleton driver and noticed a mistake (not your fault as the service manual is incorrect!)

The service manual omits KC4 but it should be this:

KI 5 - CHAIN/BEAT
KI 4 - INSERT/AUTOCOMP
KI 3 - DELETE
KI 2 - EDIT/RECORD
KI 1 - SONG
KI 0 - PATTERN

I’ve done Jaguar homebrew, this works for that too.

Can't remember if it was @mixmaster or @shattered who asked for a dump of the Conner CP-2024 2.5" AT/XT-IDE harddisk's firmware ... TeamE dumped it's up on the FTP now and can be found here.

Some time ago I relayed ROMs dumped from the Olympia Olytext 20 text processing system. Yesterday I finally got hold of a complete system that included the hitherto elusive system disk. Its ROMs are identical to the ones posted previously.

[Linked Image]

The main unit is contained in a relatively small but heavy metal case that is shared between the Olytext 20 and 30 models. While the Olytext 30 is an XT compatible with a Z80 daughter card that would need to be emulated to run the proprietary word processor of the Olytext 30, the Olytext 20 is a genuine Z80 machine with 128K RAM and two 3.5" floppy disk drives (using 80 tracks, 16 sectors/track, 256 bytes/sector).

[Linked Image]

The peripherals are an amber composite monitor, a keyboard with special keys for the word processing application and some sort of typewriter or printer, in this case an Olympia ESW 2000 C daisywheel printer that speaks Diablo.

[Linked Image]

The Olytext application is a proprietary affair that maintains file compatibility with earlier Olympia applications and can drive some Olympia electronic typewriters as printers. While CP/M was already way past its prime by the time the system was released (1986), this whole "computer" affair was still a mystery to a company that had been among the world's top three office automation systems manufacturers at the end of the 1960s. Instead of opening up to the possibilities of computers, they treated them as ever more complicated extensions to typewriters.

Files are as always on the FTP and here.

I can't fiddle with this right now but here's the basic hardware: Z80, 2xZ80 PIO, Z80 SCC (8530), NS405-B18N video controller.

Is the Diablo interface serial or some ribbon cable? Old style Diablos used a proprietary ribbon cable or was equipped with a serial extension card that could communicate with any standard machine.

It would be of interest to me to know what Diablo model the printer is based on, it is probably on a label near the print wheel if you lift the cover. t could also just be Diablo command compatible of course

From what I could gather it’s Diablo 630 command compatible and was offered with IEEE-488, serial and Centronics interfaces, this specimen uses the latter.

Yeah, most early 80s daisywheel printers were Diablo 630 command compatible regardless of interface (parallel was most common IIRC, but RS-232 and IEEE-488 existed too).

Friendly 2018 reminder: I'm still desperate to get the Bandai Wonderswan+Color IPLROMs (system boot ROMs) dumped. I'll contribute hardware+funds to anyone who can try to help make this happen.
