Transfer Apple CP/M to MS-DOS

Submitted by JMEA on June 16, 2008 - 4:59pm. Apple II

Hello. I have many text files created with CP/M on my Apple IIe (with Microsoft Softcard). I have installed a PC Transporter card and I transfer the CP/M files to DOS files (with ADOSXFER.COM CP/M utility), then from DOS to ProDOS, then from ProDOS to MS DOS (with TRANSFER.EXE PCTransporter utility). It’s a long way.
I have read about ADTPro software and I have also a SuperSerial card but I’m not sure if ADTPro can read a text file from an Apple CP/M disk and transfer it to a readable MS-DOS file. Maybe ADTPro can only transfer like a “bit copy”. In this case, can I use a CP/M emulator on my PC to read the text files?
Can anyone help me?. Thanks.

This is true. ADTPro will give you a digital image of your entire floppy disk. A tool like CiderPress or AppleCommander could then read the contents of that digital image and extract text files.

Null modem cable pinout diagram

Submitted by JMEA on June 19, 2008 - 3:34am.

Thanks for your response. I am outside USA and I need to ask a technician build a null modem cable for ADTPro serial connection. But I have found on Internet several pinout diagrams for building the cable and I am confused. Can you show me any link with the correct diagram?

Thanks

It depends on what you want on both ends. Since you have a Super Serial card, one end is going to be a DB25 male. The other end depends on your modern computer. Most likely it is going to be a DE9 female, which was a fairly standard connector up until a few years ago. Nowadays, you only see USB connectors. So, in addition to the DB25M-DE9F cable, you'll probably need a USB-serial adapter too.

If you take a read here:
http://adtpro.sourceforge.net/connectionsserial.html#Super Serial cabling
you'll see that you don't actually need a null modem at all if you have a super serial card: you can just use a straight-through serial cable, so long as you flip your jumper block to point downwards as in this picture:

My modern computer have a standard serial port and I don't need a USB-serial adapter.

I see but in any case the technician will ask to me the cable diagram (for a straight-through or a null modem serial cable).

If it's not easy to find the correct diagram perhaps you can say me a cable brand and model that you know is OK and I can buy it on USA. Thanks.

It's a standard straight-through serial cable - I don't even know what the pinout is. Here's an example from a US supplier:

Pinout diagram OK

Submitted by JMEA on July 6, 2008 - 6:42pm.

Hello again, I have used the “Common Null-Modem Connection” from http://www.nullmodem.com/NullModem.htm with Super Serial Card set to Modem but the connection fails. Surprisingly the connection is OK when I set the Super Serial Card on Terminal mode. The software is excellent. Congratulations.
