EINSTEIN BBCBASIC PROGRAMS text listings. SRLRUN.doc A bbcbasic assembly program for the Einstein which will create "SRLRUN.COM" on the Einstein's default drive. This can be used to download back *.com" files sent as an ascii text hex dump from the Einstein by READCOUT.BBC. (will work with Xtal DOS version 1.11 but not with 2.05.) srl9000.txt SRL9000 is the same as SRLRUN but positions itself lower in memory and will work with Xtal DOS v. 2.05. SRLRUN.COM & SRL9000 is loaded from the DOS prompt. It will just sit on the Einstein's screen until an ascii hex file created by READCOUT.BBC is downloaded from a PC. It will translate the hex back into code, load it into the 'TRANSIENT PROGRAM AREA" call and run the program. No need to load it on an Einstein disc first. For more about SRLRUN goto ADDING BINARY & BBCBASIC PROGRAMS FROM A PC DIRECTLY INTO THE EINSTEIN'S MEMORY READCOUT.doc When run this program will display the directory of all files on the Einstein's current default drive. It will prompt for a file name to be typed in. Ideally a *.com or binary file. File information, a "/" , then an ascii hex dump of the file sent followed by an "=" and more file information will be sent to the PC's Terminal. By using "CAPTURE TEXT" these files can be saved on a PC. Later they can be sent back to the Einstein loaded with "SRLRUN.COM" a com file created by "SRLRUN.BBC" a bbcbasic assembly program.

CPDWrite CPDREAD and DSK images CPDWrite.zip This is a fickle piece of software. We are told a 286 is too slow for it and I've found it will not work with my AMD 475 htz PC. With a 486 with win/95 installed it works OK in DOS but Not from win/95 DOS prompt. Boot from a floppy into DOS or shut down windows by using "restart in MS_DOS mode". In the cpdwrite.zip archive are four files for cpdwrite and a BBC.dsk image. Create a new folder cpdwrite on the PC extract all files to it. I have already set up "Cpdwrite.cfg" for 720k 3 1/2 floppy in a 1.4mb drive. Blocking up the right side hole on 1.4mb. 3.5 floppy will create a 720k floppy. So to try! With a 720k 3.5 floppy in A drive at the "c:\cpdwrite > " prompt type "cpdwrite bbc.dsk <ENTER>". Tracks should be read out on the screen then a return to the DOS prompt when finished. Try this in the Einstein TC01. If it dosn't work try writting the dsk image to the floppy's second side in the PC by using "cpdwrite bbc.dsk s" command. Post feed back on this please. If it works for more people there can be more dsk images for downloading. Responses from those having difficulties with CPD software. cpdread720.zip Zip archive contains all files to read 3.5 720k disks with 40 track per side Einstein formated. Seems to work on most PCs. CPCREAD.CFG already set up for 3.5 Einstein disks to be read from drive A. Create "cpdread" folder on PC hard drive extract all files from zip archive to it. With an Einstein 3.5 disk in the PC's "A" drive at the dos prompt "c:\cpdread>" type "cpdread filename" <ENTER> no file extension needed. If all goes well a disk image file should be in the cpdread directory. Not much use having CPDRead if haven't got CPDWrite working or Einstein emulation on the PC except to send disk images to those that have.
