I?m not sure to what degree one can/wish to build there own car. If one puts their mind to it; then anything is possible. I?m sure this applies only to die-hard builders and not representative of the ?average? guy/gal. One, and I may be stereotyping here, does not have the time to build much of anything is this hurried world we inhabit. I know this website caters to the experimenter/hobbyist in the computing world but I wonder how many of us have the time/inclination to build an old machine. I recently tried to revive my Coleco ADAM but couldn?t find old capacitors/transformers ? maybe in America they?re available! (I could run an emulator on my PC/Mac but to what end? It?s definitely not the same as running the real thing is it?) As for new machines I guess there are builders /programmers of Raspberry Pi?s but they have a limited use for power users and for ?old? computer aficionados of classic computing era! Do young people want to do this? They may be computer savvy but I don?t think too many have an interest in building anything, particularly from the vintage era. My friend?s grandson, he?s 7, told me the computer is a tool for getting ahead not for looking back. Yikes! Happy computing! Murray :)

Archiving CP/M 2.2 Source Code Programs to a PC (Fat or NTFS media)

by robo58＠optonline.net

Hi Folks, I have many diskettes worth of CP/M 2.2 assembler source code and programs that I'd like to archive in the PC environment. I'm worried that my media is degrading and I want to move it before it's too late. The media is mostly 8" SD or DD, there are also some 5.25" HD diskettes too. I have the original hardware and can view the media and run the programs. I'm looking for suggestions on how to move it to the PC environment. Thanks Robo

Archiving CP/M 2.2 Source Code Programs to a PC (Fat or NTFS

by f.heite＠hccnet.nl

>>> From: Robo58 <robo58 at optonline.net> >>> >>> I'm looking for suggestions on how to move it to the PC environment. IF your CP/M machine has a serial interface, I would connect it to a serial interface on your PC. Then use programs/protocols like kermit/xmodem/ymodem/zmodem/procomm/telix/hyperterminal to copy your CP/M files to your PC. Which one to use, depends on what software you have available on your CP/M system. On the PC side, you'll probably always be able to find a corresponding program. Have fun, Freek.

Building a PC - then & now

by c.murray.mccullough＠gmail.com

I was reading in a dated magazine article on the "freedom to build(a PC)": Well you can't build phone; can't build a car; can't build a refrigerator; can't build a TV. Do we have the freedom to build a computer? We did in the earliest days of the PC- the 8-bit era. Heck, that's all one could do! It was limited and is to this day. AMD vs INTEL control what we can do. Has anything really changed? Happy computing. Murray :)

USO (Unidentified System Unit)

by jnc＠mercury.lcs.mit.edu

> From: Henk Gooijen > I could not find the M5950 nor M3020 in any module list. The M3020 (and M1131) are variants of the M302 (and M113, respectively), so I don't think those are much of a clue. The M5950 I couldn't find anything about at all, but the M595 is a current mode converter for the DF11 - which I can't find much about, although it's in the '73-'74 Peripheral Handbook - but that looks distinctly like a possibility, from the pictures there.

Archiving CP/M 2.2 Source Code Programs to a PC

by mark＠markesystems.com

From: Jon Elson <elson at pico-systems.com> > Got a console serial port on the CP/M system? You should be > able to use a program like Kermit to suck up the files. Something like this was going to be my suggestion, too. The original request was to archive the source files, not the disks themselves. Virtually every modem-type program (MODEM7, for example) has at least XModem, and of course there are tons of options for the PC end (PuTTY seems to be a popular choice). Hopefully there's some serial port in the system, even if it's not the console. And you do remember how to write 8080 code and make CP/M calls, right? Worst case, since it's "Source" you're trying to archive, would be to write a simple program that just reads a file and blurts it out the serial port, with no handshaking at all. Running a serial capture on the PC would probably have very few, if any, errors. ~~ Mark Moulding
