Re: RAM write wait states

I'm not sure studying the schematics is the best starting point. Yes, it is probably the most authoritative source. But it will probably be quite difficult to follow and understand, let alone extract the necessary timing information, without being familiar with the architecture. I don't want to be ...

You only need to do an proper database export and import to new version. What had happened is that someo...

Re: IKBD-to-USB?

First few bytes depend on a TOS version. TOS 2.06 synchronizes clock with IKBD, older TOSes doesn't do that (unless some software is loaded).

Re: Wanted : SF314 drive

DIN-5 also has 5V and 12V. DIN-7 (for ST) additionally has -12V. On the forum someone showed SF-314 with DIN-7F power connector - don't know if this was a common version or not, but I haven't seen another one like that.

Re: Wanted : SF314 drive

It is DIN-5F on the power supply. So basically, there is a DIN-5 socket on a cable, and plug on the chassis. It has 5V and 12V output, but 12V is not used in last models of FDD. You may use DIN-7 power supply from ATARI 520ST, it will work without any modification, and original plug will fit.

Re: Does anyone have an original SF314 disk drive With the square button ??

SF314 was the double side double density drive. You may use regular floppy drive set to drive 0, like in any ST (media change detection may not work). In STe and STf(m) you can attach only one external floppy. Reverse connecting the activity LED won't do any harm to anything, it just won't work unti...

Re: Floppy Drive SF314 7pin DIN power connector

USB charger may have not enough power to run a 5V only FDD, and if not the power adapter itself, also the tiny wire in the USB cable doesn't help. This is definitely not the oldest drive, as it has STe style eject button, even the ones with large STf-like were not the oldest. Oldest ones, had PC-lik...

Have you opened it and verified if this is an original connector? Pinout should be the same, and 2 border pins should be n.c.

Re: Exist any Intel x86 port of Atari TOS?

TOS was unique to Atari, but its user interface, GEM, did exist in a PC version (actually Atari have ported it from PC). TOS is a mix of CP/M and DOS. Initially Atari wanted to use GEM on CP/M 68k.

PC utility to manipulate ROM images

I don't know where to put it on the forum, but I've done a small .NET utility, which I've called CartMan. It can be used to split 16-bit image into two (L/H E/O) 8-bit ROMs (and vice versa), do a byteswap in 16-bit ROM image, and "stack" multiple ROMs into one ROM image. So it may be used ...

4 bombs is illegal instruction error, likely to be caused by a stuck data or address bus line. I was recently "fighting" with a SuperMon cartridge that started to throw 4 bombs during startup. Reason - loose A5 pin on one of the ROMs. So likely you have killed your TOS 2.06 ROMs. No big de...
