t0ri Posted May 10 Share Posted May 10 (edited) Hi, I am pleased to announce that the Vortex AtOnce-386SX emulator has been reverse-engineered and reproduced. I found the type of FPGA used and read the information from the protected GAL chip. All of this was possible thanks to very generous donors tIn and GGN. Hats off to them and many thanks for providing the devices. tIn sent the DIP version and GGN sent the PLCC version. For now, this is the DIP version for the Atari ST and MegaST. A PCB for the PLCC version for the Atari MegaSTe is on the way. When I finish all the work on the project - the documentation of both versions will be published on the www - as always - for free.

Chri O. Posted Friday at 11:27 PM Share Posted Friday at 11:27 PM Impressive 😷. On your website: Quote The plan is to check whether the Ti486SLC processor, which is compatible with the 386sx, can be used instead of the 386sx processor. Texas Instruments also sold it under its own name as TX486SLC. Later, Texas Instruments also released their own version of the chip, the TI486SXLC which featured 8KB internal cache vs 1KB in the original Cyrix 😃 Quote Link to comment Share on other sites More sharing options...

Some mess without consequences. I'll bought Tx486slc and tI486sxlc2. A bit rare and expensive chips today. Especially sxlc2 version... tOri 1 Quote Link to comment Share on other sites More sharing options...
