2. M ADAPTING ELECTRIC PENCIL TO SOL AT F000 HEX FROM C000 by Louis Bucklin Enclosed is my check for renewal of Proteus My thanks to you for your continuing efforts to bring us useful information about the Sol By way of contribution I am enclosing a listing of changes that I found necessary in order to adapt Electric Pencil to the Sol at F000 hex from C000 hex It became painfully obvious rather quickly that unless one run s all Software at F000 hex the time and potential error of switching becomes too burdensome I made considerable effort to contact Michael Shrayer Software before attempting to track down the changes in the code that were required But letters were returned and phones proved to be disconnected I found this unfortunate not only because searching for the changes was time consuming but because it appears that all hope now for the upgrading of the Pencil has disappeared While Pencil remains for me perhaps the single most effective piece of software written specifically for the Sol it could benefit from error removal and extension N ast Bucklin af In some ways the departure of the Electric Pencil is a little bit like the demise of the Sol though I expect the reasons were quite different It is an enormously valuable piece of software There ought to be a means of keeping this alive I am surprised that Shrayer didn t sell rights to the Pencil instead of allowing it simply to die This wo

8. However you should be clear on one point The Helios format disks cannot be written with the VFDC Processor Tech used a unique recording format that cannot be used by other controllers on the market It may be possible to read Helios disks with a special transfer program using the VFDC but this is not yet clear So file transfer from the Helios format to the IBM format must be done by connecting two drives to the same computer one with Helios controller and the other with the IBM compatible controller or by connecting two different machines and passing data by serial or parallel port A number of Proteus members have the Tarbell single density controller and Helios controller connected to the same drive using a multiplexer feature of the old Tarbell board They are able to pass data from the Helios format to the single density IBM format using different slots in the same drive I m sure that members who want to convert old files to the new format will be able to arrange something with these people Proteus will provide a referral service for this Anyone interested in doing this data transfer for a reasonable fee should contact me to get on our list N Of course files can be moved from one format to the other Vla cassette tape Richard Greenlaw s TAPEDISK and DISKTAPE utilities move CP M files to and from Sol s cassette tape Our tape librarian Lewis Moseley can provide you with these utilities The board does not provide an automa
9. SOFTWARE FIXES The theory of this modification is that the system runs with MCSOLOS off all the time except when access to the keyboard or the screen is needed The relocation package from Morrow comes with a relocated boot loader and system equates which expect to find the DJ2DB located at F800H I had to modify the references to SOLOS to Fxxx from Cxxx to run with MCSOLOS at all In addition I had to insert code like the following to turn off the DJ2DB and turn on MCSOLOS before each call to a SOLOS routine and just the Opposite afterward Morrow s version of CP M 2 2 for SOL comes with three special routines for input from SINP and output to SOUT Changing those special routines and making one additional change in the warm boot procdure is all that is necessary 43 bytes total In COTTY delete the jump to SOUT and in its place insert the following xra a turn off dj2db out 040h by o p 0 in bit 7 21 out Ofch turn on mcsolos by o p 0 in bits 6 amp 7 call sout 0f019n mvi a 0cO0h turn off mcsolos by o p 1 in out Ofch bits 6 amp 7 and turn on dj2db by out 040h 0 p 1 in bit 7 ret In CSTTY similar code should surround the call to sinp as follows CSTTY xra a turn dj2db off and mcsolos on out 040h out Ofch call sinp get character from keyboard push psw save character mvi a 0cO0h turn mcsolos off and dj2db on out Ofch out 040h pop psw retrieve character continue balance of CSTTY as written Change CI

They are entered by first typing a left brace and then the command Example SAVE filename u will save all incoming text in file filename on unit u until you enter All incoming text is displayed on the VDM also Anything you type between the and carriage return is NOT sent to the modem neither are the brace or the carriage return they are strictly local These commands can be used at any time that there is no incoming text CON T ON PAGE 23 The SAVE command saves all incoming text in the file filename as noted above If the file does not exist it will be created with type T and with a block size of 4CO All text is saved in a buffer When 24 lines have been received a CTRL S is automatically sent to the network to Stop the flow and after all residual characters have been received the buffer will be transfered to PTDOS Since PTDOS also maintains a buffer the transfer may not always result in an actual disk write taking place After the transfer has taken place a CTRL Q is automatically sent to the network to tell it to resume sending The SEND command sends a file to the time share system When the end of the file is reached the file will be closed as shown by being displayed and the terminal bell if you have one will beginning inging at about a 1 second rate and the message Press MODE to continue will be displayed Because this program has filter routines to prevent sending or receiving most

Semiconductor MM58167 chip which provides time and date in digital form That is the following digits can be read thousandths of seconds hundredths of seconds tenths of seconds seconds minutes hours day of week day of month and month The onboard battery provides approximately one year between battery changes under normal use When the system is turned on the clock chip derives power from the computer but when turned off the battery continues the clock without interruption Having date and time available gives your system new power Here are some examples Your software can reliably determine the time by reading the clock using the clock utility program This is very useful for date and time stamping your files when they are changed so that you can be certain of which file is the latest Programmers will find this handy for keeping source code revisions in order during frequent changes as debugging is taking place A video oriented editor which can read the date and time into the edited file is available for CP M with this board Security break in attempts in business systems can be logged with date and time for later investigation That is it is not good enough just to provide password protection to keep non authorized users out of files they shouldn t access You also need to be aware of the attempt to breach the security of the system so the culprit can be found This is a key technique in discovering embezzlement attem
