I've been trying to find something which does this between my Z-100 (generic MS-DOS - not PC-DOS) and an IBM-Contemptible; specifically my recently acquired Zenith 286 Laptop. Simtel's modem programs don't seem to like the Z-100, presumably because they make direct bios calls. Kermit [ S L O W ] can be made to work, and I assume the Z-100 version of Procom with PC-Procom in the Laptop would work, but even with the PC Emulator running in the Z-100 I can't get anything really efficient to run. The Laptop comes with ZCOM which must be similar to LAPLINK (which I do NOT have), but I can't make ZCOM behave in the -100. Kermit is my last resort, but has anybody actually made one of the better things run on a -100? And am I correct in thinking LAPLINK is not PD? I don't need it unless it will play on the -100. Can anybody check whether its documentation makes a distinction between PCDOS and MSDOS and/or whether it says it won't work with non-compatibles? -- Don Malpass [malpass@LL-vlsi.arpa], [malpass@gandalf.LL.mit.edu] ...

Most communications software talks to hardware and won't run on the 100, even under pc eumlation with zpc. ` I use KERMIT at 9600 baud between my 100 and z183. Slow, but it works.

Slow, but it works. I have succesfully hooked up my old H-100 to a Z-183 using procom on the 183 and a terminal software package call BESTERM on the 100. Both supported XMODEM transfers. Also, I have BBS software that will run on the old 100 (under MS-DOS), which similar results can be made. I seem to recall 9600 bps was ok, but 19.2 only worked in one direction (not both). Both of these solutions run on the H-100 under it's normal MS-DOS (version 2.x or 3.x), and can work with only 3 x 64Kbytes of memory installed. .....rfj.....

I also have connected a Z-181 to my Z-100 through the serial port. I used Binkley and got file tansfers of 9600 baud using Zmodem. Of course, to run Zmodem properly on the '100 you have to use a RAM disk. I tried it from a floppy and it bombed. I got one file to transfer at 19200, but then it would not work again. Must be too fast for the '181 :-)

Must be too fast for the '181 :-) According to the specs for the serial chip in our Z100s, (I know, specs mean nothing) we should be able to get as much as 38400bd out of it, we may have to get the machine running at >10Mhz but it supposedly can do it. peace, Scott

As much as 38400k ... Sure the chip can run at 38400k ... but that assumes no overhead for the operating system. IBM-PC Kermit (not to be confused with Z-100 Kermit) can do transfers at up to 115Kb, but it intercepts the interrupts. Its difficult to rewrite the Z-100 routines for mere 4 fold improvement when you can transfer an entire hard disk with one command (Kermit has an associated program to send directories), and most Z-100's don't even have a hard disk. Unless, Scott, YOU want to. :-) Drew -- Drew Derbyshire Internet: ahd@clutx.clarkson.edu U.S. Mail: 108 Decatur St, Apt 9 UUCP: kendra!ahd@garp.mit.edu Arlington, MA 02174 Telephone: 617-641-3739

So what's the problem of running a Z-100 at >10MHz? They can run very nicely at 10.7MHz. Standard new motherboard with ZDS factory 256K DRAM 8MHz or new motherboard with HA-108 chip upgrade. 150nsec 256K DRAMs work okay, but I feel better with 120nsec. Just replace the 8088-2 with a 8088-1 (10 MHz) and up the crystal to 32MHz, also replace all NEC ICs except the keyboard controller (and I don't trust that) with non-NEC brands if there are any in your machine. DO NOT USE a V20 CPU at any rating. The 10.7MHz Z-100 will now blow timming windows in the Z-100 RS-232 and floppy controller diagnostics - this is a fault of the diagnostic software using loops to time events that are now too short. All other diagnostics will run normally. I can make available at cost PC Boards for a baby-board assembly so you don't hack the Z-100 crystal on the motherboard. The device is a PCB, wire-wrap socket, resistor, crystal oscillator, two wires to a toggle switch on the rear panel. You get the 8MHz from the motherboard one way, throw the switch and get the speed from the oscillator the other way. You remove U236, stick it in the device and put the device in the socket that you removed U236 from. If you socket the oscillator, you can safely experment with system speed increases, using the motherboard 8MHz to fall back on. Cheers, Gern -------

One small problem: The highest *standard* IBM-PC baud rate is 9600 baud.
Above that, you can't get within spec. So you *can* talk from one IBM-PC
to another above 9600 baud, but don't expect to talk to *standard* machines
like the Z-100.
I tried it. It don't work. Nohow.

So what's the problem of running a Z-100 at 10.7Mhz? The list you gave was a fairly impressive reason. I'm sorry Dave, rebuilding my Z-100 from the mother board up doesn't thrill me, I never did find a cheap hard drive controller for it. That fact that kendra (Epson Equity III+ PC/AT Clone) has a 71 meg disk AND controller for the price of a Z-100 disk controller is not lost on me ... nor is it lost on Clarkson, which is almost ready to give them away to charity.

I believe I bought the 8 MHz speed up kit you refer to. What does it cost to get the other half of the speed-up?

Worked fine after I figured out how to do it. :-) It helped to have the BIOS and ROM sources for reference. I wasn't able to get it to work until I started speaking directly to the uart.

I have no idea what you think you bought... Do you have a new or old motherboard, with or without hacks, what is the 8088, what is the crystal near U236, what is the oscillator on the (?) board that may be inserted in the U236 socket, does the (?) have a 'G' on the bottom?.......
