This weekend, I was given MikroKolor Color Graphics Interface by the person who designed the hardware, Paul Andresen. The basic operation was to interface a TMS9918A VDP chip to a TRS-80, Apple II, and S-100, and the output was NTSC color composite video. A color modulator was required to interface it to a TV. A two part article was written for 80 Micro in 1982 by the person who wrote the software, James W. Cole. They took out full page ads under the name of "Andresen's Electronics Research & Development, Inc." >From their ad: "The MIKROKOLOR Color Graphics interface is designed to provide the new TRS-80 Model 100 portable computer with high resolution color graphics and text capability, utililizing a standard color television or color monitor. The MIKROKOLOR provides 256 x 192 graphics, with 15 colors plus transparent. Its 3 dimensional Sprite plances provide for simultaneous display of all levels. I has four modes of operation available: 1. Text mode: Provides 24 lines of 40 characters each using a 6 x 8 dot matrix, and provides 256 user devinable characters. 2. Multicolor mode: Provides 64 x 48 color graphics. 3. Graphics 1 mode: Provides 256 x 192 color graphics, 24 lines of 32 characters each, utilizing an 8 x 8 dot matrix with 2 colors per character. 4 Graphics 2 mode: Provides the same as Graphics 1 mode except allows 16 colors per character." I'm curious if anyone else on the list has one, and has anyone used the unit? It seems like it is a pretty neat unit!

Digital Machine - Cards I Can't Identify

by tarsi＠binhost.com

Greetings, all! I obtained a Cambridge Digital machine the other week at an auction for $25. I am going through the box to identify what is in it. Being new in the world of these sort of machines, I'm pretty clueless. I've figured out some of the cards, but the following I can't identify. Can anyone help me find out what they are and some docs or webpages about them? I have listed the card #, where it's located in the machine relative to the drives and the PSU, and any numbers, symbols, etc I have found on the card. I have also on some of them listed what they might possibly be. I have already figured out the processor card, which is an 11/73 processor (KDJ11-AA (M8192)) and the hard drive is a Fujitsu 2312K. The floppy controller is a Sigma Information Systems Floppy Controller. That and one of the cards is a DRV11-J. The memory is Chrislin Industries 512K board. The rest I'm rather clueless about. Thanks in advance, Nathan tarsi(a)binhost.com Card 1: Drive Side - Went to Tape Drive LSI-50 Alloy Eng C.P.D.

European micro's

by kenziem＠sympatico.ca

It looks like I'll be making a trip to Europe in late May or June. The flight is to Amsterdam. Are there any places of interest to visit with regards to vintage computers, swap meets, or collectors with surplus wishing a small trade (fit in carry on)?

Yeah, it's a hassle, but I think it's worth it to get easily-portable code. Only a few lines need to be changed to move the code to another machine. All in all I would recommend this book. Plus you, Fred Cisin, got double kudos ;>) Glen 0/0

Need paper tape encoding format

Of course.) Lots of unix (including many BSD/Linux) systems have a program called ppt (usually in /usr/bin/games or similar) which takes an ASCII string and outputs a facsimile of paper tape. The dormat is just ASCII in binary form, with columns arranged exactly as your little sample above, except there are 8 columns, and a hole represents a '1'. What you do with the 8th coulmn depends; on PDP-8 systems the top bit was often set for ASCII (but it has special significance to binary loaders), on some systems it would be unused, on others it would be the parity bit. Do a Google search for "ppt paper tape" and you'll find info about "ppt". -- Pete Peter Turnbull Network Manager University of York

HP IPC (Integral PC) documentation / instructions needed

by vassilip＠dsl.cis.upenn.edu

Hi, I have just acquired an IPC with the basic ROM, a 1Mb ram board and a second HP-IB board. I have downloaded the IPC images from the Peter Johnson's site but I can't get the IPC to read them. So I want to check whether the floppy drive works (the mechanism was stuck and I have to take it apart and clean/oil the mechanism). I guess that PAM is more or less useless, so I am trying to access the floppy from Basic. Basic looks similar to that of the Series 80, but I had no luck with the MASS STORAGE IS command. Is there a list of commands somewhere. Also I tried connecting a 9122D external HP-IB dual floppy, the system didn't seem to notice it was there. Finally, anybody knows how to format a floppy on the IPC? Thanks **vp

My last VMS question: %INIT-F-VOLINV, volume is not software enabled

by gunther＠aurora.regenstrief.org

Hi, last night was supposed to be the last time I was going to boot VMS before it will be forever banished from my house (because we finally have an Ultrix 4.5 tape and my uVAX-II runs NetBSD and Ultrix and can write to TK50 :-). The only reason I had to boot VMS once more was to write myself a uVAX diagnostic tape. And of course, whenever you start VMS you're in for trouble :-) I'll cut it short and ask your help for the following matter. Part of the diagnostics tape procedure is to initialize a file system on the TK50 with this command (I didn't invent this, it comes right from a DEC supplied DCL script.) $ INITIALIZE MUC6: ELAN When that runs the tape scrunches and spins happily until suddenly: %PBC0, Port is Reinitializing ( 45 Retries Left). Check the Error Log. %INIT-F-VOLINV, volume is not software enabled What the heck does that mean? Yes I have VOLPRO privilleges and I think the tape writes fine, as I have used it for other reads and writes. It happens with both VMS 7.1 and VMS 5.4. There is probably some "obvious" thing you have to do, but what? Here is the error log, if it tells you anything: ****** ENTRY 3677., ERROR SEQUENCE 110.

Some computers with internal SCSI drives do not have a separate terminator at the source (host adapter) end of the SCSI bus. They depend on a terminator being present in/on the first drive. With no terminator at all, the resting signal level on the SCSI bus is not pulled up (to about +3V) so the open-collector bus drivers on the host adapter or on the hard drive can't produce any detectable signal by pulling the bus lines down to ground. Computers that are built like this include some Macs, all NeXTs, and probably others that I don't know about. Not SparcStations, they have internal bus termination built onto the motherboard. < http:www.scsifaq.org> carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

Rest In Peace, Ludwig Van Beethoven is correct. The programmer had finally figured out the original coder's intent, and found it had nothing to do with the program at all. The original coder seems to have been amused by seeing the composer's year of death at that address and added the comment. The point of the yarn was to be careful in relying on the comments. I've gone through source code where I had a historical trail of changes, and found that some programmers change the code but don't update the comments. They should be shot for this behavoir, but then there might not be enough programmers to go around... ...if only... -dq > -----Original Message----- > From: John Allain [mailto:allain@panix.com] > Sent: Friday, March 01, 2002 10:15 AM > To: classiccmp(a)classiccmp.org > Subject: Re: Write only programming > > > > 1827: MOV AX,0001H ; R.I.P.

It appears no one has ever implemented TCP/IP on a Z-100, at least under CP/M-86. As nice as these machines are, I was really surprised to learn that there is no active Z-100 group, at least not that I can find. There is a usenet group which gets about one post each month.
