Another perspective on the Minimodem C: it definitely does have a lot of features, but I am unsure about its reliability. I used one for about a day some months ago. It is extremely small and comes in a cheap-looking (and feeling) soft plastic case that opens (Really! You can peer right into the internals of the modem). The modem operated fine... I just don't think that I would buy it because it doesn't look like quality stuff. The 1670 is much more rugged and is nearly the same price these days. But what the heck--buy a 2400 bps modem! They are really cheap these days too (compared to a year ago). Kent Sullivan Microsoft Corporation The opinions expressed above are all mine, however silly they may be.

Here in Winnipeg we have a BBS running at 2400 baud on a C-64 . The Land BBS (204) 338-3423, 24 hrs and is a fairly serious board. It is supported by two disk drives, a 1541 & 1571. The modem was obtained from Computers Direct (see Computer Shopper) The bbs program is called Dark Star(?) and the sysop is very familiar with the workings of the C-64 and did the necessary tweaking of the software. Hope that encourages you. * QNet 1.03a2: Pokey's Place Winnipeg, MB (204) 253-1342 (HST) <<SmartNet>>

The system will even slow down, if you do only 1200 bps. The internal software has to generate each bit of a byte, start- stopbit and the parity. This is a hard job. So, two years ago, a friend of mine thought about a solution of this problem. He created a cartridge using a 6551 ACIA interface chip. With this chip the C64 is able to speed up to 19200 bps. The costs are about 30$. The problem is, there is no public domain software out, supporting this cartridge (for the C64). There _is_ software for the C128. Please ask me, if you are interested. Ingo

This works on my C128, but has not been tested on a C64. I've been told by a cbm person (who reads this list, but I don't remember his name) that it may not work on a C64 due to differences in the DOT clock phase. A friend of mine is working on testing that now. So I don't guarentee this curcuit to work on all machines (just mine 8-). If you're willing to help debug it for your machine, let me know and I'll explain what the problems would be. I'm interested in making it general enough for all 64's and 128's (but I can't afford to buy all 64's and 128's to test it on!). I will most likely be posting another version in a few weeks that takes care of these problems so if you're not the type to debug, you might just want to wait. This circuit maps the UART into the IO area at $de00. The 6551 has four registers. These are mapped to $de00 through $de03. I don't have the chip specs handy (you can get them when you order the chips, though), so I really don't remember the specifics, but they are something like: $de00 Trans/recv register. Any incoming data from the modem is put in the register. Likewise, outgoing data to the modem is put here. $de01 Status register. The bits here tell things like if the chip has data for you or if it's ready to accept data, etc. $de02 Control register. Sets parity, word length, etc. $de03 Command register. Controls when interrupts are generated and a few other things. The chip specs have all the info you need to write a driver. It's really pretty easy. When you initialize, just set the parity, baud and stuff. Then turn on the interrupts and you're ready to go. The board will then generate an IRQ when it needs attention. Read $de01 to find out why it needs your attention, process the data and return from interrupt. > Do you have driver software? I'm looking for examples of how to > configure, read and write bytes.... I had a general one that read data into a queue and then served it to the users program. It ran under C Power as a function. I accidently erased the disk, though. It was only about 50 lines or so. If someone wants to get it built into a terminal program, I'd be willing to help write the driver.

Devon: IMMMM :solution of this problem. > He created a cartridge using a 6551 :ACIA interface chip. With this chip the > C64 is able to speed :up to 19200 bps. The costs are about 30$. D.B: :I recently built a similar thing, but mine is less than $15 in :parts.Or do you mean he's selling the full built and tested :models at $30? I've got PostScript version of the schematics :for mine if anyone's interested. HMMM I would like to try and build one of these gizmos. I am sure there are many more interested in such an upgrade. Would either of you gentlemen post the schematics & parts list in this echo. Thanks for your cooperation.
