You know it's rare if the only reliable picture you can find online is a low resolution one on a German Ebay link aggregator site ...

https://picclick.de/Minolta-PCW-3-302592823215.html

On behalf of TeamE I've posted ROMs and pictures for a Minolta PCW-3 office system (looks like a PC/typewriter combo in the vein of the Olytext 20) on the FTP and here.

There's another German site by a couple who are tentatively collecting information about the PCW-1, and that is a 186 PC running on DOS 2.11. I've sent them an email ... let's see if something transpires.

I finally had the courage to tear apart the BASF Digilog 7120 I got a few months ago.

[Linked Image]

It turned out to be easier than I thought because the whole monitor/disk drive frame flips up and supports itself in that rails contraption on both sides - pretty cool, but the machine is still a major PITA to work on.

Before I open it up again to dump the keyboard controller EPROM (a 2708, no less), I need help identifying this chip

[Linked Image]

in case it needs to get dumped as well.

I've uploaded photos, some documentation and dumps of the various PROMs, EPROMs and PALs found on the BASF 7120's boards ... it would be great if someone could take a look in case I missed something.
I've searched available Motorola documentation from the 1980 timeframe, but I couldn't find the above IC. Files are on the FTP and here.

A guy on the German VzEkC forum documented his PDC Clipper and put the files on his FTP.

ftp://ftp.dreesen.ch/PDC_Clipper/Pics/20181127_155004.jpg

This is a C64 mainboard mated with new ROMs, an electroluminescence display, a 3" floppy drive and optional BTX module with acoustic coupler put into a nice briefcase. He's provided ROM and disk dumps, documentation and pictures.

I've put the stuff on the MAME ftp as well, crediting him in the archive.

Just spotted a ROM dump of an Argentinian TK90X-A (according to this post, the Brazilian one is a TK90X-B and has more internal differences than just the ROM), which can be downloaded here: https://www.dropbox.com/sh/vqoi6b4kaijy0id/AACIp5U8TA895f8Na0JoILYxa

Real hardware footage, here: http://www.youtube.com/watch?v=YlGKMOmk9Wg

Sources: this tweet and this post
Things that she mentions:
-The computer is not necessarily faulty even if it shows some corrupted attributes on startup (other TK90Xs she had did similar stuff).
-That model has black keys, which makes it from 1985-1986 (later models were released with grey keys).
-This ROM displays a "Ejecutado 0:1" message instead of "OK 0:1" as in other dumped versions.
-She dumped this ROM via software using a "SAVE" command, recording the audio, converting to TZX and then trimming the data.
-The "Portuguese" ROM in the download link is a one-byte modification that she made herself. Not sure how MAME handles this kind of variations (would it just change that specific byte from the "Machine Configuration" menu instead of using a modded ROM? Also, a Brazilian version with that ROM revision might not actually exist..).

EDIT: Oh, just remembered that the Amstrad CPC may be a similar case, with the different manufacturer names.

It obviously didn't make it very far, but have been trying to fill in the gaps on info on the unit. I actually will be taking it to a friend this month or so who will dump it to see what code is there on the ROM chip.

With ByteSwap: http://s000.tinyupload.com/?file_id=93571807841560828608

Feel free to have at it and see if there's any info to be had. I doubt the prototype ever really becomes working again, but worth it to archive the code.

at best it looks like some kind of graphic rom

at worst, bad dump / fried chip

note, there's a Dallas DS5003FP and battery on there too, which I can only assume is somehow related to the DS5002FP suicide chip you find on Gaelco boards etc. I can also only assume the code is/was in the SRAM, and is probably long dead. If the battery voltage is >2.8 (and at no time has anybody removed the battery or accidentally triggered the suicide mechanism, which can happen if you so much as look at it funny) then the sram might in theory still contain the code, and the dallas might in theory still contain the key for it, but if it's been sat disused for so long, in unknown conditions, that's kinda unlikely.

it is likely that all the code was in the SRAM anyway and all that is dumped is something display related.

More from where that came from, so that it doesn't get lost:

As far as we could tell, it was used to demonstrate and test controllers and peripherals. The code even mentions the Activator and the Mega Mouse.

There is another version of this ROM out there (Version 4.0), but given the earlier date and lack of version number on this one...it could possible be V1.0. If anyone has a concrete idea as to what this was for, I'd love to know. Otherwise, feel free to mess around with it!

It should also be noted that, in this ROM, the VDP is set to run in H32 mode (a resolution setting that uses a width of 256 pixels - 32 tiles), rather than the commonly used H40 (320 pixels in width - 40 tiles).
Pretty cool tidbit on the VDP. I wasn't expecting some grail item, but always was curious as to what it's actual function and story were. Attempts elsewhere to figure out what this was got me the wise guy answer of "it's a universal driver test program."

Also, images of the cart and such below. I'm not able to use the IMG tag yet, so will have to work with links for the time being.
