My question is, what sort of bps download speed can I expect to a 1581? Will it be a true 9600 download? How about downloading to a RamLink? What kind of bps download speed could I expect with that configuration? You'll get 9600bps (about 960bytes/second) on the modem. However, the modem transfer has to wait after each block while to data is being written to disk. If you're writing to a stock floppy, the disk writing time may be as long than the transfer time. However, writing to a RL or HD is fast enough (with JD) to be nearly irrelevant. Aaron -------------------------------------------------------- Aaron J.

With this you don't need any modem also. Only thing has to be done is,plugging this cable to the computers (just two computers, one to many communication with this kind of schematics causes data collision). After plugging, and loading terminal programs to the computers, just send the program, from one of the machine and receive it using the other one. Schematics for this cable are at the end of this e-mail. Final notes: . If you don't have RS232 interface to plug this cable, there is good schematic s in the comp.sys.cbm.faq. If someone asks for the schematics, I can e-mail it. . You can use Novaterm9.5 at c64 side and Lynx at the IBM side for example. . You have to use same transfer protocol at both sides (eg. xmodem ) . If you want you can put one of the terminal programs into BBS mode. . In case of not having soldering experience, this cable should be done by someone who has. Otherwise a short cut is probable. . You will built this cable with your own risk. The Schematics: --------------- 1.) DB-25 to DB-25 Null-Modem cable. db-25 db-25 Parts List ----- ----- ---------- tx 2-----------3 rx .

Greetings all, Every now and then most lists send out a reminder about basic admin. stuff and so on. This is one of those.

In the body of the message, use the command phrase: index commodor f=mail if you want a list of all the archive filenames. The files will have a name-style like "commodor log9402c". The archive files go back several years and will take a lot of time to read. The numbers refer to the date; eg: 94 = 1994, 02 = month 02, c = 3rd week. -------------------------- Alternatively: If you want to "get" a particular file, use the command phrase: get commodor log9402c f=mail in the body of the message. The "f=mail" thing at the end is important, because it forces the listserver robot to d/l the msg via email. -------------------------- This all assumes your system uses the Multinet, (ie: mx%), protocol; other systems may need the email-address prefix to read `WINS%` or `IN%` or 'JNET%' or `SMTP%` etc. -------------------------- If you want to post a message to the list, DO NOT address it to the Listserv as illustrated above. Use the *list title* instead - eg: mx%"commodor@ubvm.cc.buffalo.edu" Using this form of address will post your message to everyone on the list. ---------------------------- The main thing to remember is: a) Commands - (ie: Index, Get, Digest, Subscribe, Signoff etc) - are *always* sent to the Listserver; in this case - listserv@ubvm.cc.buffalo.edu b) Messages - (to be posted to the listmembers) - are *always* sent to the list; in this case - commodor@ubvm.cc.buffalo.edu ----------------------------- In case of problems contact the owners of the list, who are, (1996)....

If you have the Swiftlink Cartridge , 38400 bps works fine. If you want to do it by yourself there is a schematic called 'datapump', which is something similar to Swiftlink.

Hello all, I recently picked up a color BMG monitor with cable that I use on my C128. The problem is when the 128 is on, there is no color. I connected the 128 to a tv and the color works fine so I don't think that is the problem. While looking at the comp.sys.cbm faq I was comparing my DIN connector with the one displayed and they are different. The color pin (as listed in the manual) is not being used. Actually, the DIN connector on my monitor cable doesn't even have all of the pins that are necessary. Can someone tell me which pins I need to hook up? I understand that I guess only four of them are used: sound lum/sync color ground Is this correct? I guess what I need to know is which ones go to which jack on the other end (monitor)? For instance, does the sound and ground go on the audio jack, and the lum/sync and color go on the video? Is it that simple. Can I get these parts to make the proper cable from Radio Shack? I would really like to see color on my monitor.

How do you pass control between the two processors with software? I am also wondering if it is possible to trap the Z80 I/O port events on the C128?

I think I've tried this before in order to play Modem Wars. If I remember correctly the only way I could make it work is cut the telephone wire connecting the two modems and reverse the wires. I'm not sure but I think the reason for this is that you have to make sure the transmit wire of one modem is the receive wire of the other modem. Try it out if straight through phone wire doesn't work. Allan =END=
