A call from the wild! Another good month. anit your letters coming! As for me, my wife and | had a baby boy on September 16. So if {| seem a bit tired, that's the reason. This month | will begin the first of two parts on the ROM character generator.

Character Generator BASIC ROM—Table. The character generator table in the BASIC ROM is a set of 8 x 64 = 512 bytes beginning at address 7680(1E00H) and ending at address 8191(1FFFH). There are 64 characters defined for the T/S 1000 in the table. Each set of 8 bytes names one character. Stack the 8 bytes, one on top of the other, and you will see how the character is “drawn.”

oul a

f = y ba be vebdl,

Let's look at an example. If you were to PEEK bytes 7680 to 7687 you would find 8 bytes, all zeroes. The first 8 bytes are used to generate the first character in the T/S 1000 character set. Think of the 8 bytes stacked one under the other and convert from decimal to binary:

(PEEK 7680) =0=| 00000000 | (PEEK 7681) =0=| 00000000 | (PEEK 7682) =0=| 00000000 | (PEEK 7683) =O0=| 00000000 | (PEEK 7684) =0=| 00000000 | (PEEK 7685) =0=| 00000000 | (PEEK 7686) =0=| 00000000 | (PEEK 7687) =0={ 00000000 |

The arrangement of characters shown in the box is how the computer “draws” the characters “space.” The zeros represent blank space. Now, since each 8 bytes represents a single character, let's figure out how to-find the start address of any character in the table.

10 INPUT A$

20 LET CHARADDR = 7680+8*CODE A$

Therefore, the start in the character generator table address of the character “A” is:

DOES 3 JUNGLE JIM USE A GORILLA PRINTER?

CHARADOR = 7680 + 8 * CODE "A" =

7680 + 8 * 38 = 7984

Let's see the way the computer draws this character:

(PEEK 7984) =0= | 00000000 | (PEEK 7985) =60= | 00111100) (PEEK 7986) =66= | 01000010| (PEEK 7987) =66= | 01000010 | (PEEK 7988) =126= | 01111110 (PEEK 7989) =66= | 01000010 | (PEEK 7990) =66= | 01000010 | (PEEK 7991) =O= | 00000000 |

Doesn't it look like the “A” printed on the TV screen or the printer? Here’s a program to draw the characters in large letters on the screen:

5 CLS 10 PRINT “WHAT CHARACTER?” 15 INPUT A$ 17. IF CODE A$ > 63 THEN GOTO 5 20 CLS 25 PRINT “GENERATOR BYTES FOR—", A$(1) 26 PRINT 30 LET CHARADDR=7680+8*CODE A$ 35 PRINT TAB eee a iad 40 FOR I=CHARADDR TO CHARADDR+7 50 LET DECIMAL=PEEK | 55 REM CONVERT DECIMAL VALUE TO BIT PATTERN OF CHAR 58 PRINT TAB 5,"*" 60 FOR P=7 TOO STEP -1 65 LET BIT=INT (DECIMAL/(2**P)) 70 IF BIT=1 THEN PRINT okt 75 IF BIT=0 THEN PRINT “” 80 LET DECIMAL=DECIMAL-BIT*(2**P) 90 NEXT P 100 PRINT “*” 110 NEXT I 115 PRINT TAB 5,“****"**"""" 120 PRINT 130 PRINT “WAITING” 140 PAUSE 65535 150 GOTOS5

FASSWORD SECURITY by John Kemeny

This article could iso be titled “if you break my ade you will break my heart.” The BREAK key is used to interrust a BASIC erogras. The program halts with some @rror report on the bottom ef the screen. In fact, the STOP statement is just a type of BREAK. Machine code programs ordinarily can not use the BREAK feature.

In many applications you do not want the user to be able to BREAK into your program. For example, you may not want the clerk entering sales slips into a@ program that calculates pay- roll commissions to have access to sensitive salary data. But more generally, you don’t users who accidentally hit BREAK to be confronted with a screenful of listings.

The T/S 2066 has a siaple way to keep users from BREAKing @ program, namely by inserting, as the first program line:

10 ON ERR 60 TO 10

This causes conditions which would otherwise generate an ~wror report to execute 60 TO 10 nstead. Interestingly, @ normal ermination, where the programa goes past the last line, will halt the program--so put a STOF atatement at the end when using this technique. ‘

Unfortunately, this siaple technique prevents anvone from BREAKing a running program. A better method would allow users who tnew a “secret” password to be able to stor the program. The following short routine does just that.

10 ON ERR GO TO 9000

20 REM your program here

z0 GO TO 20

9000 REM password routine

9010 LET p$="secret"

9060 LET qt=q$+as

9070 IF LEN p$>LEN q@ THEN 6C TO 9040

9060 IF pté=qs THEN ON ERR RESET

9090 ON ERR CONTINUE

The variable pt holds the password and can be changed to any string. Lines 7050 to 9070 are used to debounce the user’s input. It takes advantage of the fact that null string “" can be added to the input qs at will. he BEEP at 9020 is necessary to

Stagicate to the user to start entering the password. This is because the BREAK feature is disabled while in the routine, so the user can get out of sync.

A COZY NOOK FOR MACHINE CODE IN THE TS2068

The area in RAM used for Bank switch- ing starts at 25365,(in the single display node )and contains 323 bytes. This space can be used to hold ma- chine code,so long as bank switching is not used. I have tested this area by loading it with zeros and by using 4t for machine code and have experi- enced no difficulty with the opera- tion of the TS2068.

Unused fixed addresses are located in the system variable area at 23681,

8-16K Switch for Cheetah 64K Rampacks by Doug Hoiles

Last year I purchased the English made Cheetah 64 kilobyte rampack for the sole reason of its very low price. Fortunately, it turned out to be a good quality unit, but with two flaws: virtually no documentation and no way to switch out the 8-16k block to enable the use of other add-on peripherals that operate from ROMs per- manently wired to use this address space. This was no problem initially, but about 6 months later I purchased a word processor module with ROM software that occupied this space. Natu- rally they were incompatible, My options were to buy a new, smaller RAM that did not occupy this space, buy a switchable RAM for well over $100, write only very short letters (under 2K), or figure out for myself how to modify the Cheetah to switch out the 8-!6K block. I chose the latter, but considering how little I knew about computer logic, it wasn't easy.

First, I had to study the board and draw a schematic.. I probably did not need the entire schematic, but not knowing what I was doing, | figured that too much information was better than not enough, so 1 effectively completed it. I then borrowed a Texas Instruments TTL hand- book that showed the function of the logic chips in the package so I could decode the operation of the device. 1 also had to contact MOSTEC for information on their 64k dynamic RAMs. T still do not know how everything works, but I was able to figure out which traces had to be cut and where to attach the jumper wires to the DPDT switch which I mounted through a small hole cut in the back of the case. On the second try! I still do not know why my first try was unsuccess- ful, but I have two short pieces of wire rejoining traces erroneously cut that first time. It looks kind of messy, but it works.

If you wish to make this modification for yourself, here is how to go about it. There are probably other ways that would work too as there are usually more than one way to do something in digital logic, but this approach works by blanking the column adjust strobe to pin 15 of all RAM chips when it would otherwise be strobing the 0-16k addresses, thus preventing "refresh" of the dynamic memory. 0-8k must also be blanked since the Sinclair ROM works in these addresses and is so blanked in the factory unit, 1 will not cover the theory of the logic further as that would be too lengthy, but I will be happy to discuss this with anyone who wishes to call me at (408) 737-1776, at least to the limited extent of my understanding.

First, buy the smallest double pole, double throw switch that you can find. I! mounted a slide switch on the inside of the back of the case so that the slide just barely sticks above the surface of the case through the hole I cut in it. The switch stays with the board on dissassembly and is secured to the case with two small woo. screws which, when assembled, screw into twe ¥"lengths of 3/16 dowels glued to the switch or you could probably use sheet metal screws thru the wing holes. You will also need some short lengths of small gauge, flexible wire, I used 22

gauge wire because I had some handy,.but | recommend 28 gauge stranded with thin insula- tion for flexibility and ease of wiring. It must, of course, be solderable.

Next, remove the board from the case. See figure 1. The top eight ICs are 64 kilobit dynamic RAMs. The bottom five ICs contain the decoding and addressing logic. The left two ICs are 74LS157s and serve primarily to direct data to or from the correct addresses in the RAMs, The next two are 74LS139s and it is in this area that you must modify the existing circuit and attach the new switch leads, Figure 2 is a front view of IC4 (showing parts of IC3 and IC5) and shows a trace which must be cut running fro:n

in 14 of IC4, between pins 3 and 4 of IC5 to ROMCS (pin 23, bottom) on the edge connector. The other trace which must be cut is on the bark of the board and is shown in figure 3 running from pin 14 of IC4 to pin 12 of 1C3. Cut the leads where shown as pin 12 of IC3 and pin #4 of iC4 must be isolated from each other as wei: 4s from the edge connector,

Four wires to the switch and two jumpers on the switch all solder on the back of the board and the detai! in figure 3 should be adequate to show you how to wire it. Use the schematic and the detail of the 7415139 chio and you should

MODIFICATION FOR THE CHEETAH 64K RAMPACK.

have no trouble figuring out where to cut and where to solder. If unsure use an ohm meter to trace all leads before cutting or attaching your leads. All that you are doing is changing the ROMGS output signal from pin 12 to pin 13 of 1C3 in the “out" position and back to pin 12 in the "in" position. In both switch positions, this output signal goes to pin 14 of C4 and to the edge connector.

I should point out a possible problem before turning you loose. While my word processor module works fine occupying this address space with the switch in the "out" position, my Hunter CMOS RAM board does not. [t works fine by itself, but not with the Cheetah. I have not yet taken the time to determine if it is a decoding problem with my modification or an unrelated problem, but if you wish to make the modifica- tion for this use, you may want to investigate further before acting.

As with any modifications to hardware, | take no responsibility if it does not work, you do it wrong or if Cheetah may have modified the circuit so things are possibily not as described (unlikely), Work slowly, be careful, understand before you cut, check with someone else before acting if you have any doubts and you should have no problems.
