The Mumford Micro Speedup Board

I have been an avid reader of your magazine ever since it came out & am very glad that support for the earlier machines still exists, at least in the 'States'. In this country our User Group is the only support there is for anything but the latest MS-DOS Tandy machine. I am still using (amongst others), a much modified Model I that I bought back in April 1978. One of the modifications that I have is the Mumford Micro speed-up board, bought in June '83. I don't know if that firm still exists,...

The Author

The author of this nice package appears to be Frank Durda IV, one of the members of the MAD. group. All of you Model 4P owners are already familiar with Frank's work. Why Because he wrote the ROM in the 4P. Anybody who bothers to explore the 4P ROM will find Frank's initials embedded therein. What do you think the puzzling fdiv, stands for You got it (Long ago JBO, of Northern Bytes fame and now Software Wizard of Montezuma Micro, wrote an article about that ROM, but even he guessed wrong about...

More Chaos

I want to say how much I enjoy TRSTimes. I find something (usually several things) in each issue that interest or help me. I'm one of those diehard Model III users -no upgrades other than the RS graphics board - but I still get a kick out of it. I especially appreciate any Mod III, TRSDOS 1.3, and Z80 assembly language items. The program CHAOS BAS (by Robert Doerr, in the recent issue of TRSTimes) inspired me to edit the program so it could be run on Model III, as well as Model I. It is listed...

Clan Revisited

My Clan program is on TRSDOS and, according to the banner, it is version 1.3 Wed July 1981.1 need a date patch to extend the date acceptance. I had not felt that I needed to worry about it, but apparently the program uses the system date in some of the error trapping routines, and now I am unable to make some record entries with 1988 dates. As I do not have the CLAN program, I am not able to to give you a specific fix. However, I can tell you this if CLAN refuses to accept dates after 12131187,...

Contour

Glad to see that you were able to fit my CONTOUR program into your May Jun 1990 issue of TRSTimes. However, there was one little problem In glancing through the program listing, I noticed that occasionally the less-than' lt ' and greater-than' gt ' symbols were missing. I found this in three different program lines Line 80 should end with ELSE IF A lt gt M GOTO 70 Line 230 should read IF LM lt 0 OR LM gt 900 GOTO 210 Line 1060 should end with IF K lt 0 GOSUB 1330 While a good programmer could...
