Has anybody started working on a mindset driver for MAME? Two Mindsets, one confirmed working, were discovered at the liquidation of computer reset in Dallas. If I had a technical manual, I would already be dumping the BIOS...

There's some documentation on Bitsavers. If the ROMs and disks get dumped I'm confident we could have some fun with it.

I've poked around the internet looking for info on these, found this so far:

From Bitsavers docs:

U59 252004-005 ROM OS Lo
U60 252004-006 ROM OS Hi

U78 253001-001 i80186
U17 253002-001 i8042 (KP Custom)
U-- 253003-001 SG Custom
U43 253004-001 RHB Custom (VLSI VC2030B)
U42 253005-001 RP Custom (VLSI VC2029) ( " CPU V3089 VC2029 VTI 48-Pin DIP Ceramic Gold " ?? )
U16 253006-001 i8042 (Sound processor)

From http://www.digibarn.com/collections/systems/mindset/

Roger Baderscher (President of Mindset) was the head of Atari's Home Computer Division from 1980-1982 and had quietly commissioned the design of a new modular computer system while at Atari, using Atari Industrial Design resources and tapping into one of Atari VLSI engineers Chris Rhode. Roger, Chris and about a dozen Atari Home Computer division engineers would leave Atari in 1982 and form Mindset, and their quiet skunkworks project would become a reality.

I've got some nice brochures and other materials I can scan and send to you, I have every module, expansion pak and controller made for the system and Chris Rhodes has promised me that eventually when he digs up his old schematics and notes he'll send them my way for the M-1001 Mindset. I also have 2 M-3000's which are the rackmount JVC'd versions of the Mindset system that JVC used in-house after they bought Mindset in 1986.

From http://atariage.com/forums/topic/42993-what-the-st-almost-was/

The ST would later have a Blitter chip, similar with the chip designed by Chris Berg (former Atari engineer) for Mindset.

That was actually from Curt Vendel. He has not been in good health, I don't know how he is doing today. He sold his collection in 2013 to ???
http://www.vcfed.org/forum/showthread.php?35096-Mindset-Computer-Corp-collection-for-sale

Curt had a web presence for his Mindset stuff, but it doesn't seem to be on line any more.

CHM has a couple of systems and a fair bit of software.

I thought I imaged the disks. Since there were so many ASICs I thought the chances of simulating it were pretty slim
and there hasn't been any interest until now.

There's possibly only one game for it (Vyper), but it's by Synapse. Imho, they were one of the best game publishers of the early 80s. smile

Curt is doing great today, it was touch and go for a while, but he has made a full recovery, and is, as of recently, focused on Atari-centric preservation, while doing various bits of contract work to get the 7800 expansion module out the door.

I'm wondering, if someone were altruistic enough to get the VLSI decapped? wink

I'm a little confused about the concept that we're dead in the water on ASICs without documentation or decaps or whatever. MAME's entire history is reverse-engineering custom hardware, including hundreds of ASICs. Yes, we'll take anything we can get, but let's get the ROMs to start up before we declare things DOA smile

that's true.. and having spent time with this machine, when it was new, it was really an amazing system, ultimately squashed out because of the onslaught of IBM...

@Al Kossow, I tracked Curt Vendel's Mindset hardware and software directly to the CHM. He had everything that ever existed, including all the development software, and it is now in the CHM collections.

This is highly problematic, because that means it's in the warehouse, and the warehouse is literally like the ending scene in Raiders of the Lost Ark. This means, it will never again see the light of day, unless some billionaire decides he wants to look at it.

(Sorry, I have _very_ bitter feelings toward the CHM and the way they treat many of the things they've curated.)

Ok, I'll simply apologize. I'll take the hit and say that my feelings toward the CHM are wrong.

All I want is a better interface to computer history museums and the ability to interface these artifacts with those who have the want and ability to preserve them, before the actual artifacts fail, because they are all on borrowed time.

I know our collection VERY well, and everything Mindset related came in before 2003.
https://www.computerhistory.org/collections/search/?s=mindset
We have all of the software I know of in the building I work in, and I thought I had already read the diskettes.
I'm checking with the registrars if there is anything Mindset related that came in that I don't know about.

I checked with the registrar and the only thing post what we have cataloged is an offer in 2015 for a mindset cpu and expansion box from Bruce Levy
which we declined.

We do not have Curt's computers

It's just a rom, you don't need a tech manual to dump it.
Are you going to do this, or do I need to request one of our machines and do it myself?

I do not have the machine here, but will try to do it when I can get access to it (hopefully it will be at the DFW retro meet this weekend). Need to thumb through the tech refs to find where it is on the memory map. If you get to it before i do, great. smile

Actually, thinking about it, I'll just bring my TL866 to the meet and dump it with that.

MAME is inevitable, Mister Anderson. (WIP by Olivier Galibert).

TSCHAK: hopefully the machines you can get to have different ROM versions. CHM's is 1.07 so there's plenty of variety. And dumps of cartridges would be welcome.

Also, if anyone has the "Software Developer's Guide" (SDG), I'm *extremely* interested. It seems to have a lot of hardware information.

Might anyone have the vyper game around somewhere? I’m guessing it must be quite rare

Amazing! smile

And yeah, will work with the machines that are here in DFW to get ROMs. The massive excavation and liquidation at Computer Reset has been happening for the last couple of weeks, and two and a half units have been found so far, there may be more.

PLEASE try to save any Mindset keyboards before the keyboard collectors get them!!

also, joysticks, mice and any cartridges

yeah, believe me. I fucking _HATE_ keyboard poachers. We were able to save two complete systems, and one is missing a keyboard. I am hoping there is at least one more.

As it also happened, Computer Reset was the recipient of _ALL_ of IBM's PCjr liquidation.

Five trailers full.

Give the keyboard poachers all the PCjr "chiclet" keyboards. That'll teach 'em.
