Un petit appel à tous les gens qui bricolent dans le #clavier pour ordinateur : je suis à la recherche d'une solution pour avoir un clavier (design classique de préférence) mais avec une sortie en #rs232, donc avec conversion #keycode -> #ascii intégrée.
Ça doit pouvoir se faire en reclaquant le #firmware du clavier, je suppose. Si vous avez des pistes, je veux bien poster une #gif89a pour vous remercier :)
SerialBackup - backup your CP/M / ZRDOS / ZSDOS system via serial, e.g. to a modern BSD or Linux box.
Only transfers changed file sets.
I have a device here that is called a "ComVerter" by a company named Frontline. It is supposed to convert between RS-232 and RS-422/RS-530, but unfortunately my (used) unit came without any documentation and there does not seem to be much info about it on the internet.
Before I take this thing to a friend with an oscilloscope, I thought I'd ask if someone know this device. :)

The technician who soldered that RS 232 cable did his job very well
I would have soldered in a much neater way but it worked

I rewrote 2 DiskSumo bottleneck routines in 6502 machine code (against original plan, I started to optimize sending):
- read a disk sector into buffer
- send buffer as #Xmodem packet
With 1200 bps #RS232, floppy disk dumping speed dropped from 90 minutes to 40 minutes, getting closer to line rate.
New machine code inlined in #BASIC lines is under 20 screen lines per routine. This is a "type in" program, so I need to optimize my verbose machine code syntax as well.
@W6KME So glad I’ve held on to a box of these real cables (both 9 and 25 pin) keeping cables, cross-overs, 9-25 and M-M and F-F adapters though multiple moves in recent years. Just used a 9 to 9 last week as a matter of fact. They can have them when they pry them from my …

@0h00000000 That's interesting. I'll check it out.
But also sets off a whole nother set of bells in my head.
Second... if an ideal #FPGA design has your design independent of your hardware, using an FPGA that lets them vendor lock you because of a hard-core is worse than using FTDI.
First... I fundamentally have hated #USB since I first wrote a paper about it in 1996 or so. It is a terrible set of hacks trying to replace #RS232 and it has failed in all manners. I should write a blog post.
