We are thinking of building a card for our Amiga based on
the Motorola application note 'A 68020/881 Platform board
for evaluation in a 16 bit system.'
We would like to hear from anyone who has already done
this and of any software conversions and patches that are
available for the Amiga.
Also can anyone say whether there is any software ( public
domain or otherwise ) which will enable the full 68020/881
mnemonics to be used in assemblers and compilers for the
Amiga.
Thanks in advance,
--

One was made by and outfit known as CSA. I don't know their current status. The Amiga is supposed to contain the basic software hooks to take care of 68000/68010/68020 compatability, but I've never heard anything as far as 68881 support. -- George Robbins - now working with, uucp: {ihnp4|seismo|caip}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

The CSA 68020/68881 board is alive and runs well. A developer I know has one. Word is that Manx' next release of Aztec C will have a 68881 support option. Word is that treatment of the 881's floating point registers during multitasking will be fixed in Amiga release 1.2. (I do not work for or represent CSA, Manx, Amiga, or anyone else.) Charles Poirier

It will accept five plug-in boards including: 1. A 68020/68881 board (14.~ MHz bus) 2. A 512kByte 32-bit RAM board 3. An SCSI interface board 4. Room for a 20MB SCSI HD in the box (they can supply) They are phasing out their "piggyback" board ("A"-type) because of certain internal inconsistencies of the Amigas they have installed them in. They still have some in stock along with 32-bit RAM to fit with the piggyback. The Turbo AMiga box is shipping and selling from backorder. Shipping is 30-40 days ARO.

-.-.-.-.- Hi, I just got the Sept. issue of Byte. In the What's New column on page 31, there is a picture of the CSA expansion chassis. The price is $5475. That's right --- Gaaak! The features are as previously described. I guess that would make sense if one imagines the Amiga itself as a fancy terminal for the CSA box. Actually, if multitasking is more important than one high bandwidth task, buying 6 Amigas (about the same cost) seems like the way to go. --Bill Bill Mayhew Northeastern Ohio Universities' College of Medicine Rootstown, OH 44272 USA (216) 325-2511 (wtm@neoucom.UUCP)

You misunderstood the ad. $5475 is the price for a complete "Turbo Amiga" which includes an Amiga, a CSA expansion box, the 14 MHz 68020/68881 board, 1 MB (or 2?) extra memory, and a 20 MB hard disk. The expansion box alone is only $995. I have no connection with CSA--just wanted to set the record straight.

I also misunderstood the ad. Does anybody have any idea about the prices of the other pieces? 68020/68881 board $? Extra Memory $? 20 Mb hard disk $?
