Hi Everyone....
I am looking for any guru type who can tell me what to do......
In my note 1243 I mentioned I was getting my MEGA 2 upgraded. I
had an additional 2 Meg Ram (DRAM), and a T16 "Add-speed" (By Fast
Technologies......
Now most of the things I have on my HARDDISK (MEgafile 30) won't
run! They act like they are executing and then they get 2 or 3 bombs
and ALWAYS say "Bus Error".
They installed a switch to turn off the caching, and when turned off,
some of my telecommunications software works, and some games will work
for a little while before they get the same BUS error.
What should I do? Anything I execute from my floppy drive works, so I
assume that the additional speed is too much for the Hard disk drive.
Is there some software I can use to slow down the hard disk access
(like was done in the early IBM PC days.....???? Has anyone fought
this battle? )
Or am I now stuck with a non-functioning Atari because I wanted to
speed it up?
ANY suggestions would be appreciated...
Thanks (sigh)

I'm not sure but it sounds more like you need the buffers in your mega
upgraded. This is a known problem with add ons in the mega, they load down the
bus to much for the buffers ('244's?) to handle.

| 1252.2 | Replace the Driver | VNABRW::KRONSTEINER | Thu Mar 05 1992 07:13 | 10 | |
Lets assume the ST-memory is ok. there is a good chance that the
bus-drivers (buffers latches) work at their limit.
Start to replace the 74ls373 with (74f373, or 74al(s)373, or 74hct373)
next do the same with the 74ls244.
I changed to F- type TTL-chips and was able to reduce the Waitstates
for the rom-access on my accelerator-board. ( got bombs with the LS)
With HCT-type chips I got bombs on an intermittend base.
Have no experience with AL or ALS chips but they should work also.
