Re: Spare STe board.

Atari keyboard in fact is a stand alone microcomputer which communicates with Atari over the serial link. The communication protocol is documented, as well as the source code (ASM) for the keyboard microcontroller are available. My IKBD RTC module intercepts the communication between ST and IKBD, an...

Re: Spare STe board.

STe board will fit STfm case it is also possible to put it into a tower type PC case. It is not a big deal to make an adapter to connect standard PC keyboard and mouse, or you may get CosmosEx, which does this and much more. Other option is to sell it ;)

Re: Trudie - The Next IDE Board

WinCUPL has a huge memory leaks, in my case the first symptom of this is that syntax highlighting crashes when I use the editor... it also produces unpredictable output files (part of the code may be missing), after working in GUI/Editor for a while. I have used it only a few times... but more or le...

Re: Trudie - The Next IDE Board

So I guess the ancient WinCUPL? If so, then my hint is - when you finish writing code, save it and close WinCUPL, then start it again, load your project, don't touch it, and then compile it. You can also use a Prochip Designer, for writing and compiling CUPL code for ATF15xx. Third option is to gene...

Re: BLiTTER in short 520ST

I think I've seen such mod once... you need to cut just 2 tracks, as in STf you have to desolder only 2 bridges. Just 68 wires, and you're done ;)

Re: Plastic yellowing: Light + heat?

I think the yellowing may also have something to do with using gas stoves/cookers in house where the Atari is/was kept.

Re: 520STFM - TOS upgrade confusion

You may look for 27C1000 (NOT 010 nor 1001) EEPROMs, but they are likely to be 200ns ones, so on the very border line of the acceptable latency for a stock 8MHz ST. They are 32 pins, but the "excessive" pins can be tied together and hooked to VCC (except \OE which should be tied to GND). You may als...
