CP/NET

by SPEDRAJA＠ono.com

Thank you, Rich ! It would be very useful for me. The version of CP/NET that I'm using is 1.1, but the 1.0 is a good choice too, I think (with the documentation). Yesterday I proceed to extract and compile the RS232 version of SNIOS. Actually, the CP/NET requester do a full load, but cause of one parameter (always$retries, if I remember well) appears to hang itself and don't returns to CP/M. The problem can be too in the particular CCP that comes with CP/NET, and this can fail in the reload after the load of CP/NET main block, but this is a matter to investigate. Once I solve it, I must locate what SIO is using CP/NET to try to establish communications. Next step would be to check what SIO or Serial Ports are defined under ALTAIRZ80 with its IO Device or Port Identifiers. After this, it must be modified the SNIOS to select one free and safe IO port. And finally comes the SIMH matter... Map one of the simulated SIOs with one real RS232 can be relatively easy under Linux/Unix, but not under Windoze (perhaps with one IP to RS232 mapper I've used sometimes) and this make me think in one interprocessor solution (that links two copies of SIMH running at same time) applied in the HP2100 simulator. This would suppose to link the simulated RS232 of a couple of SIMH with one chain mechanism already implemented in the HP2100 sim. But, of course, the funny thing would be to connect one Altos 586 with MP/M with one PeeCee with SIMH running ;-) Thanks again. If you want to send me the CP/NET stuff by mail, this is my address: Sergio Pedraja Calle San Luis 4, 1 39010 Santander Spain I pay the shipping costs. But, of course, the email is more economic :-) Cheers Sergio ----- Mensaje Original ----- Remitente: "Rich Beaudry" <r_beaudry(a)hotmail.com> Fecha: Jueves, Agosto 21, 2003 5:22 am Asunto: CP/NET > Sergio, > > >I am trying to obtain one copy of CP/NET or MPM/NET. > >In .dsk format suitable to be used with SIMH simulators. > > <snip> > > >I can't locate two binaries, MAIL.COM and SERVER.RSP > > I have a disk (8", SSSD) labeled "CP/NET 1.0".

Low Level Format

by Innfogra＠aol.com

There is another command to run. To get rid of the partitions you will need to use FDISK. Once you get rid of the three partitions and reformat it as a single partition you should be OK. I would use DOS 6.22, because that is what I have. Paxton Astoria, OR

CP/NET

Sergio, >I am trying to obtain one copy of CP/NET or MPM/NET. >In .dsk format suitable to be used with SIMH simulators. <snip> >I can't locate two binaries, MAIL.COM and SERVER.RSP I have a disk (8", SSSD) labeled "CP/NET 1.0". I also have a photocopy of the User's Guide for CP/NET (3rd Printing, 1981). The files you are looking for are not there, but perhaps you have a different version of CP/NET. Mine appears to be complete, judging from a quick look through the manual. There are two .COM files for electronic mail (SNDMAIL.COM and RCVMAIL.COM), and there are also "server" versions of these files. Also, the only difference I can see for the server side is a change in NETWRKIF.RSP. There are full directions for altering the server and client setups in the manual. >In the good side, I could generate the NETWRKIF.RSP >file using the indications in the CP/NET manual.

I think >it would be great to allow the simulation of one >MP/M-CP/NET-CP/M network with a couple >(or more) of SIMH AltairZ80's running at same time. My manual also only mentions serial devices (in fact, it even suggests sample 7-bit and 8-bit serial protocols, and message formats). According to the manual, NETWRKIF and SNIOS would have to be altered for a new device. It would most likely be very difficult to alter them to work with new networking hardware. If SIMH connects the emulated computer's serial ports to the real PC ports, then perhaps it would be best to go with two computers, hooked by serial cables, one running MP/M and CP/NET ("master"), and the other running CP/M and CP/NET ("slave") Hope this helps, and if you want, I can supply a PC-format disk with all files from my CP/NET 1.0 disk. I could also supply a scan/photocopy of the manual as well.... Rich B.

Floppy interface

This will help in understanding normal formats. Of course, you do not have to use these. There are a number of control and status signals to deal with head load, motor control, stepping, index detection and door closed. There are usually to data lines, one for read and one for write ( with the exception early 8" that had built-in clock/data separators. Typically, the clock and data are encoded with one of several methods. FM, MFM and M2FM are a few. These are methods of keeping the clocking with the data. On floppies, it is necessary to have regular transitions of the write signal ( no long strings of constant levels ). This is because most early read heads used coils and required edges to be detected ( coil heads are differentiators ). New hard disk heads may use techniques that see the actual strength of field. Most soft sectored formats use illegal clock/data sequences to make the beginnings of sectors( by illegal I mean that they can't exist in the data portion ). These are usually called address marks. Like I said, look at the data sheets. They explain these things. Dwight

Data Systems Design DSD-880 8" floppy and Hard Drive

by TRASH3＠splab.cas.neu.edu

I was going to do this offline, but I have had a couple of requests for this info, so I will put it out to the list. I do not have the manuals scanned, so I will excerpt from them. If any of you reading this have one of the systems (or part of) that ends in an 8, meaning an 8 MB drive, I would especially like to hear from you in order to try to see if it is the electronics or the actual drive that I have that is bad. I have 3 working 30 MB systems, and I think I will be getting rid of them soon, as I have moved the software over to a PC. Here goes the explanation on the DSD 880 series from my perspective. Data Systems Design (Qualogy) made two disk subsystems for Digital Equipment Corporation (DEC) computers. It is possible they made other models, and other adapters for Prime or DG, but I don't know anything about them. The subsystems were external, in a 19 inch wide case, about 24 inches deep, and about 6 inches high. They used a ribbon cable, 26 pin to connect to the backplane adapter. The adapter had diagnostics upon bootstrap and a bootstrap prom on it. The models were DSD 880xnn, where the X was either an S or a D, meaning a single sided 8" floppy drive or a double sided 8" floppy drive. The nn was either 8 or 20 or 30 for the megabytes. The floppy emulated an RX02 or the double sided emulated an RX03 with a patch to the OS. The winchester emulated an RL01 (8 MB with some waste), a short RL02 (10MB) with a couple of megabytes of bad blocks, or 2 or 3 RL02s with a patch to the OS for 3 RL02's. I am also doing this mostly in context of RT-11. The manuals I have are dated 1982 and 1984, so that gives you some idea of the age. The bootstrap will boot either the floppy or the hard drive. There were two different formatter/controller cards, models 8840 and 8841. There were a few different adapter/interface cards, 8832 and 8836 for q-bus and 8830 for unibus. The winchesters had head and spindle locks located in access doors underneath, for shipping. There was a modification to the 8836 to support 22 bit addressing. The 8832/8836 are dual wide boards, while the 8830 is a quad board. The configuration of the 8832 and 8836 are in two jumper blocks at location F4 and D3 on the card. These control the location of the RL CSR, the boot address/enable, the floppy CSR, dma burst length, the RL and floppy vector addresses and the priority levels. The unibus version has similar features in 5 locations. The units shipped with a diagnostic floppy that had a diagnostic monitor, a floppy and winchester exerciser, a diagnostic program for the winchester in RL emulation and a scan program for bad blocks. The hyperdiagnostics panel is similar between the 8 and 20/30 drives, except the mode 0 stuff is different. I will start with mode 1 stuff, where the panel has mode and class (left,right) Mode 1: floppy disk format stuff class 0 format double density class 1 format single density class 2 set media to double density class 3 set media to single density class 4 set media double density and scan class 5 set media single density and scan Mode 2: system tests class 0 floppy disk exerciser and write class 1 ditto, but no write class 2 fixed disk exerciser class 3 floppy/fixed disk exerciser, write floppy class 4 single pass of class 3 class 5 single pass of class 3 without write class 6 floppy/fixed disk exerciser, no fixed/floppy write class 7 fixed disk write enable, use this before fixed write tests Mode 3: more hardware tests class 0 controller switch and indicator test class 1 general controller tests, alu,mem, crc, pll class 2 alu and serdes test class 3 memory test class 4 crc test class 5 pll test class 6 display microcode version mode 4: floppy disk alignment stuff. pretty specific, must have sa800/sa850 floppy maint manual mode 5: read/write tests class 0 single pass sequential scan floppy class 1 butterfly seek floppy class 2 butterfly read floppy headers class 3 sequential write/read floppy class 4 sequential scan hard drive class 5 butterfly seek hard drive class 6 sequential write/read hard drive class 7 fixed disk write enable ( do before 6) Mode 6 and 7 are for offline backup and restore, except 7 - 7 which is to set the floppy-type flag on the winchester bat track map to tell the system if it is a single or double sided floppy, or no floppy. Finally there are 40 or so error codes that can pop up in the diagnostic display. Hope this satisfies some of the curiosity. Joe Heck

Article Reference: Linux -- The New CP/M

by jwstephens_2000＠yahoo.com

Microsoft wins because of the thing he mentioned about development support. They support developers. Developers love Linux and support it, but it is a pain to develop for Linux compared to microsoft. The business case he makes about absorbing and running microsoft applications is probably right too, but I doubt that Microsoft will allow it to happen. There are too many "no reverse engineer" minefields in the EULA now to allow it to happen anyway. As he said, rolling out thousands of units during the implementation of a massive application needs really solid support and tools. I don't think that the fact that everyone can roll their own development is necessarily a plus for Linux. Having the mass that an IBM or Microsoft lends with their market position to making it possible to have a single product from top to bottom to use is way cheaper than the current Linux way. You have Redhat and SUSE, but they still have the problem that if you make a commercial Linux App you have to have a RH7.1 RH7.2 RH8 and RH9 all with different nuances (and not minor ones) to support the market, where with Microsoft you usually need only one, or can buy a package to handle the differences from someone.

Can you help me? ? Fabio
