No development since 1996.
Building this yourself, probably pointless.  You'd have a near unique bit of hardware and practically nobody around to develop for it.

One day, we'll have a modern-day 7 or 14 Mhz 65816 expansion that'll co-exist with at least some of the other ones like U1Meg, VBXE, IDE +2 etc.

True true ).
Just for info...

[Rybags]

That thing looks massive too.  Looks like maybe it lives outside the machine connected via PBI ?

My wish would be for something compatible and minimalist and internally installed.  Really all that's needed is some fast Ram and maybe local fast Rom (flash-mem), if people want RTCs, IDE, whatever, then let them do that seperately.

Rybags maybe ATMEL ARM (hmm ultrafast 6502 emulation - so you will be abble add your own instructions for example) will be cheaper than original 65c816...

Interesting!  I have heard of several different accelerators, but not this particular one.  This one looks a little similar to the one from a Polish developer a few years ago, but it was an XE version.

Yep,

further information can be found in the Abbuc magazine - but only in german language. Last not least, this project is long long dead and obsolete. Whenever someone comes up with a 65816 project, this lasts for a few years, but sooner or later the project seems to be dead and very few Atarians built or ordered a 65816.  I remember these projects:

- Atari in the 80s, nothing ever came out of it, no software, no hardware; but I guess Curt Vendel still has all the plans and schematics;

- "Dataque" (Jeff Potter and Chuck Steinman) in the early 90s, nothing ever came out of it, no software, no hardware, nothing;

- Hyper-Speed XL/XE by Mario Trams, in the middle of the 90s, plans, schematics and some software released in Abbuc magazine, nothing ever evolved though (seems as no-one ordered the hardware)... Mario also demonstrated his enhancement at two (of the annual) Abbuc meetings...

- someone told me there were also plans (or at least articles) in Atari Classic magazine, but since I don`t have it, I don`t know if its true...

- FTE ?!? After all their big plans with SpartaDOS, SDX, Action, Basic XL, Basic XE, etc. it would not surprise me if a 65816 was also planned... but nothing ever came out of it...

- KMK/DRAC030 released some sort of manual, software, a compatibility list and other stuff here:

http://drac030.krap.pl/en-pliki.php

- Bob1200XL released a 7Mhz version for Abbuc hardware contest some years ago, he also talked about his 65816 here at atari-age:

http://www.atariage....page__hl__65816

simply use "65816" as search function for more 65816 related topics here at atari-age...

- afaik, just two years ago Guus Assmann released a 65816 pcb at Abbuc hardware contest (this time both the 6502 and the 65816 were on the same pcb)...

Nevertheless, after all these hardware, software, text/information releases about the 65816 the thing did not really evolve. Looks like most Atarians want to keep their 8Bit Atari as an 8Bit Atari (and not a 16 Bit machine; if so one could easily buy a "Commodore ST" or an "Atari Amiga" )

(above edited for clarity and relevence)

There were some Dataque 65816 boards made, someone in a Atari User group i was in, had one... Altho i havnt talked to him about atari in probably 20 years, last time i did talk to him, i think he got rid of all his Atari stuff tho, but not sure...

I do know where to find him, if need be I can contact him and get details...

sloopy.

Most of the 65816 systems (that I've been familiar with) have been either incomplete or "sort-of" worked.  By this time, Atari users expect certain things from their systems, and I think that you could put this in an overall category of "legacy compatibility."  We'd like our Black Boxes or MIO's to work properly.  Many pieces of software take advantage of expanded memory (not linear).  A good accelerator (IMO) needs both linear and expanded memory to offer the user a desirable upgrade.

Dataque's Turbo8/16 worked (I saw it one our user group meeting) but really offered little tangible benefit to the user.  It was 1.79 MHz.

There was a commercial 1.79/7.16 MHz release (saw one at Las Vegas in 1998), but the company was already out of business by the time I checked.  Several of these were supposedly sold to cable TV operators.

Bob's XL7 works and is a neat development, but it lacked the ability to use a hard drive and had no expanded memory.  (BTW, you ought to see KMK's MultiBasic FLY on the XL7.)  I haven't heard any updates on Guus's work on revising that accelerator for quite some time.  (???)

Fte's "Sweet-16" works fine at 1.79 MHz, but has no linear memory, so you really can't do a whole lot more than with a 6502.

There was another 1.79/7.16 MHz accelerator that ran at 1.79 in base memory and 7.16 MHz in extended (linear) memory.  Several folks took a whack at developing these, but afaik, only one prototype ever actually worked as intended. (?)

Perhaps Bob1200xl will update us on his current WIDE project.  I truly believe this one will work, and will offer "a complete package."

Will these ever be "mainstream?"  Probably not, since there will likely not be much software developed that can take advantage of the hardware.
But will it be neat? ABSOLUTELY!!!

John Maris (from the Dutch Pokey magazine) made an experimental prototyp 65816 130XE for me. I had to test it and make some programs on it. As lack of time caused by school etc, i didnt do a lot with it. I tested some bankswitching techniques and the newer op-codes for the 65816. We had some ideas of converting SNES games to the 65816 or so, but nothing really came out of it.

Simply said: I had an 65816 + stereo-sound upgraded 130XE, but didnt do much with it.

Hello guys

IIRC John Maris is a member of AtariAge since yesterday.
