Hello all
I hardly ever use forums, so pardon me for being dumb.....
I take it PM is Personal Mail, if so how do you do it from this forum.
I don't have a problem with creating colour scans of everthing Cortex related so that it can go it the public domain and be of use to someone else.
The problem I am having at the moment is no access to an adobe writing software to create PDF's from my scans.
I did have adobe on my work laptop, but it seems to have turned into vapourware!
The only thing I can't scan without destroying it is the doorstop databook on the TMS9900 family, so I am not going to do that one.
I am truly amazed at the Cortex emulator, I had the same program running on the MK2 and the emulator at the same time.
Needless to say the MK2 was faster ;-). The emulator was running on an old lab PC the is a P3 clocked at 1GHz.
I would be interested in seeing seeing the source on how the Cortex emulation is done.
I have beed messing around with FPGA's for the last month and got to wondering about an FPGA replacement for the TMS9995 or even the whole Cortex (inc TMS9909 and the infamous 74LS2001). The are some IP cores avaliable for the TMS9995, but I dare not ask how much they cost for fear of going into a coma.
I am looking at building an updated Cortex on a single eurocard, using original TI chips but modern everthing else including a V9958 or the later V9959. The ancient DRAM would be replaced by a single and not so ancient larger SRAM. The "quaint, ancient, rare as hens teeth, expensive as ????? TMS2564's" will be replaced by a "nice, standard, common as muck, cheap as chips 27c512". The cassette interface can go as well..., LOLMA.
I have been scouring the internet for traces of a TMS9909 and some suitable diskdrive for it (BBC B ones should do the trick).
I have CDOS 1.2 on a 5.25 floppy (I don't know if it is any good).
That reminds me, would it be possible inthe emulator to map the Cortex drive to a physical PC drive?
I have been offered a TMX9909 by a former work colleague, he says it is a prototype TMS9909 but he can't gaurantee it will work in the Cortex or that the chip is in fact a worker.
