I have ordered tyhe board from them. It sounded good to me, and frankly with
as much time as I spend going from edit to compile/assemble to debug, etc., any
improvement on the speed will be greatly appreciated. The topper on the whole
deal was the blitter socket. Whenever Atari makes them available, I'll be
ready...
So, here are the details I got from them:
Current first rev boards should be back this week, and should be shipped as
soon as they get them in. They said they would call if there was trouble.
The first board is for older style 520 ST (not STFM) due to the motherboard.
(No problem for me, I have a REV A board!)
520 STFM, 1040 ST, and MEGA ST versions of the board (all the same) should be
available in the first week of August.
*FAST* ROMs are needed to allow the upgrade to work properly. *FAST* ROMs
(with TOS on them) are not available at this point! If you have a 6 chip
set (most MEGAs have 2 sockets) you can hack the ROM sockets somehow to make
them *FAST* ROMs. (I don't know how, they said instructions are included).
You also need to remove your 68000 chip to install the upgrade. (I have a
soldering iron... :-)
The speed is switchable. (I guess the switch will come out somewhere...)
The price quoted for COD delivery is $299.95
This seemed very fair.
Considering all things which have occurred concerning accelerator boards:
1) I heard the JRI upgrade was not significant
2) MegaByte here in Houston (Strange Systems) are not likely to come out with
their board (although all problems have supposedly been overcome).
3) No one has one yet...
I considered this to be the closest thing to a real product. The company
(so they have stated) has made upgrades for the IBM-PC, so I would assume they
can deliver.
I will let everyone know what I find out.
