Don't forget there's no magical "Cosmos Bus", everything has to go through the ACSI port. So more stuff on ACSI -> much less responsive hard disk drives.

Re: Falcon 030 Hw mod

Accidentally found this old thread, just for the sake of completeness, yes, this seems to have an attempt to install second clock patch after the previous one (presumably the 74F08 version) didn't work. However it's done a really strange way, it's fed from R216B, i.e. after the clock signal split be...

Re: ct60e with magic 6.20

I have also noticed that if I don't boost Videl resolutions (standard 640x480x4b instead of 800x592x8b with VI2), SCSI transfers under TOS + CT60 seems to be stable. I didn't have time to do many tests nor to test this with Magic to confirm this observation, so I will stay with "seems". S...

Re: Automation project with an ST

It's perfectly doable and to various extent used by many current Atari programmers. :) The only challenging part is bootstrap process, i.e. how far you want to go (emulate a hard disk, boot from cartridge, emulate a floppy, ...) after that everything is under your control. Also, perhaps you should c...

Re: chipmunk (serial numbers database) for Atari computers

Yes, the Blitter is part of the Combel IC. I guess for cases like this (where it's clear that some part is done only one way) it should be preselected automatically. The more I think about the Blitter, the more I think it shouldn't be there at all. For instance, Falcon has an option to have CODEC so...

Well, it's a sticker so no rocket science to remove "D/C" and put "J" there. ;) Yours is PAL-B (so was the other "J" I saw), the -003 tells that.

One of my Falcons has motherboard revision CA401332-003-REV-J. Produced in July 93 according to the serial number. Interestingly, you're second person to to tell me this (rev. J from 7/93). Rev.

You can do similar trick as Evil/DHS did years ago:

Re: Falcon serial numbers

I'd love to know whether there were any Atari (!) Falcons in revision later than D/C. From what I've seen I think there weren't. C-Lab later produced Ks but it seems that Atari never really got past D/C.

Re: Almost there... (XaAES crash and Mint reboot)

It seems like CT TOS does not use the video setting from NV-RAM at all, even when "replace NV-RAM" is unchecked in ct60conf.cpx. On my Falcon NV-RAM was set to VGA, 80 column, no linedoubling, 2 colours. But when booting in 060-mode it used RGB, 80 column, linedoubling, 16 colours. I had ...

Re: Almost there... (XaAES crash and

Just make sure you can boot to MINT & XaAES without NVDI. This is really a terrible advice. That NVDI requirement is there not for fun, CT60 can't patch Blitter accesses so as soon as the OS asks underlying VDI for something and that something uses the Blitter -> crash. NVDI replaces all routin...

I'd say you should go with the US -- you certainly can't use CE's mapped disks (it requires an Atari OS) but raw access should work.

Did you make sure that the BOOT video mode - not XaAES video mode - is a VGA mode? Also, what happens if you let the TT-RAM-test finish? Does the TT-RAM pass the test?

Low pass filtering of the clock signal. One reason to do this is to minimize EMI issues.

Actually as I've realised, this is really removed in C and later revisions, same as R221 is 0R, not 33R anymore.

And perhaps it is -- one of the Atari ECOs recommends to remove C208 from the base clock line (the one which feeds the infamous three/four resistors):

Re: Falcon 040 Afterburner for sale

Yeah, but the CT60e is made like this deliberately -- to provide better stability and yes, to allow the keyboard + addons fit in the standard case. I don't see any deliberate design choices in the AB. :D

Thanks! And since you're so smart ;), what it is if there's a capacitor instead of resistor used? (i.e. one end touches the signal line, the other ground).
