(Not saying Curt ever had them, but if somebody had them, it would probably have been Curt) But somebody might have already mentioned this... Sincerely Mathy I think the only thing he got to release was the 1090 board and the z80 mechanical. Quote Link to comment Share on other sites More sharing options...

I still use Serial RS-232 for radio control and radio programming. I bought the proto boards to try my hand at developing a RS-232 card interface 1 Quote Link to comment Share on other sites More sharing options...

The original one is pretty outdated and undocumented. It would take a long while to decipher the design. I also have not seen the .rom file for it. Ken How's your progress on this??? 1 Quote Link to comment Share on other sites More sharing options...

Then we are good to go on the length and width measurements. I can guestimate the height from Ken's card. Edited June 10 by DavidMil2 edited for spelling.

Yeah, I know how that goes Were you able to source the JED or equates for U1, the PAL chip? Quote Link to comment Share on other sites More sharing options...

Ken Is this the ROM? 1090-ParaSerial-2716_crc-1bdb5.bin The PAL shouldn't be hard to reverse engineer based on the schematic. (I've already decoded the registers.) 2 Quote Link to comment Share on other sites More sharing options...

Geister Posted Saturday at 02:06 PM Share Posted Saturday at 02:06 PM Looks pretty good to me. Are you developing tooling as you go or are these all handmade? Quote Link to comment Share on other sites More sharing options...

This first one will be mostly all hand made. If people like it enough to order some, I'll set up some CAD files and try a local fabrication company (I say local, it's in a nearby town). I did buy a hole punch machine, but it's so worn out, the top punch sometimes misses the bottom and hangs up. DavidMil2 1 Quote Link to comment Share on other sites More sharing options...
