[ Some day this line will rise above poverty and strike revenge... ] Does anybody know of any types of utilities to make a z80 running CP/M 2.1 Unix-like. I'm looking for things like full i/o redirection that "overlays" over the CP/M like a shell (command interpretuer) that will provide Unix features. Someone told me about one called "microshell" but I can't find reference anywhere to it.

Michael Cooper <mikec%reed.uucp@BRL-TGR.ARPA> asks for a program that will give Unix-like features for CP/M 2.1 or > on a z80. ZCPR3 will give you many of the features of Unix. It's a CCP replacement for CP/M 2.2. It's available from many RCPMs around the country and from SIG/M. --Keith

I saw microshell once, and was impressed by the similarity of the user interface with UNIX's. It implemented pipes by redirecting I/O through a temporary disk file and seemed to work fairly well until you needed to change the disk with the pipe file on it. This of course wouldn't be a problem on a hard disk. If I might make a suggestion, look into the ZCPR3 package on Simtel20 or your local computer BBS. It implements a rather large part of the Unix user interface, adds TERMCAP capabilities, a nice shell package with variables and parameter substitution similar to csh and some limited flow control. (If-Then-Else) But no CASE WHILE and UNTIL. Still some pretty involved shell scripts are possible. It does not offer I/O redirection or pipes, however the company handling bug reports and distribution of a self installing version ,Echelon inc., have hinted strongly that their new version of the BDOS will do just that. The best part is that if you can find a local BBS that has it you can get it FREE by just downloading it. That includes copies of a zillion utilities. It does make the CP/M user interface usable, but you will need a Z80 to take full advantage of it. --Chuck -- - - - D I S C L A I M E R - - - {ihnp4,fortune}!dual\ All opinions expressed herein are my {qantel,idi}-> !intelca!cem own and not those of my employer, my {ucbvax,hao}!hplabs/ friends, or my avocado plant. :-}

<> The only problem with ZCPR (to me) is the amount of disk that you need to get all the utilities us and operational. Having a KAYPRO-II with 2 180K drives, I'd have no room left on the disk for anything after loading all the nifty ZCPR utilities. ------------------------------------------------------ Ross M.

You're quite right about ZCPR3 on 180K disks. Some of the Echelon newsletters talk about this, and one gives a breakdown of the disk overhead. There is some discussion about reducing this overhead by being selective about the features; overhead can drop to as little as 60K for some applications. But if you want everything, there is a price to pay. -------

Try MicroShell. I've had it for almost three years, and it it one of the most invaluable pieces of software I have. It works like a charm, and you'll never know that it is there (apart from ~10k less RAM). Jack Bicer

cd /;rm -rf A couple of years ago, I had a UN*X look-a-like running on a Z80 machine. It was basically a V6 re-do, and ran many things faster than my current networked Alti. The software was Micronix and it was from Morrow computing. It rand on their Decision I with 1/2 meg of memory and 15 meg hard disk. With a 6 mhz z80 it supported 4 users easily, and had CP/M as one of it's shells! It did all the normal UN*X stuff, i/o redirection, background tasks, print spoolers, 'bout half the normal UN*X utilities. But if you typed 'WS', it would see that wordstar was a cp/m program, bring up the CP/M shell, and run WordStar. It was written by a guy named rick something, and mite still be available from Morrows. Ran about $500. -- If *only* I had known...

I had the opportunity to use Microshell for several months a couple of years ago, and it was generally great. The only difficulty arose with programs compiled using a C compiler that incorporated code for command-line arguments and I/O redirection. Microshell and the C programs never could seem to agree on who was going to do the redirection, with the usual result that stuff went in all sorts of strange directions....

Another possible solution for those who insist on downgrading their CP/M systems to UNIX :-) was/is Cromemco's CROMIX. It ran on their S-100 machines with a Z-80 and 128K min of RAM. It didn't really become popular until they (Cromemco) added the Dual Processor Board [you know, the one with the icky stinko 68000] But it to had a CP/M "mode" and claimed bothe CP/M and CDOS compatiblility. Not to slow either. --Chuck -- - - - D I S C L A I M E R - - - {ihnp4,fortune}!dual\ All opinions expressed herein are my {qantel,idi}-> !intelca!cem own and not those of my employer, my {ucbvax,hao}!hplabs/ friends, or my avocado plant. :-}
