I got no answers, but a couple of requests to post an answer if I found one. Here's what seems to work so far. DOSVEC ($0A) memory location points to what SpartaDOS refers to as COMTAB. ICD has documented its use of COMTAB memory, here are the relevant bytes to test: 1. COMTAB + 0 - jump instruction ($4C) 2. COMTAB + 3 - jump instruction ($4C) 3. COMTAB + 6 - vector (NOT a jump instruction) Atari DOS's, as well as SuperDOS, SmartDOS, will fail test 1 and 2. Test 3 is necessary because MachDOS passes test 1 and 2; but MachDOS DOES have a jump instruction at COMTAB + 6. SpartaDOS and DOS XL will pass all three tests. PS: One of the Sparta COMTAB vectors is to a file crunch routine which returns the next word on the file line in a small buffer in COMTAB. However, this is the usual Atari machine language format, incompatible with Action strings. I did a filename cruncher which returns the filenames in Action strings, if anyone thinks it will save them time send me mail (I don't receive the newsgroup distribution at present). The routine works with SpartaDOS and DOS XL. Dick Curzon Digital Equipment of Canada PO Box 13000 Kanata Ontario K2K 2A6 Canada.

I have an XM-301 modem now, but am tired of waiting for it constantly. Any suggestions are welcome. I KNOW that this question is boring to those users who could care less, so I ask that you e-mail me. Thanks. Tim Charron tpcharron@Watmath.waterloo.edu p.s. I'm going to be in Toronto the start of September, and if anyone in the area has a modem they're willing to sell, give me a call (after Sept. 8). I'm in the phone book. ------------------------------ Date: 15 Aug 87 02:58:23 GMT From: hp-pcd!uoregon!omepd!littlei!reed!percival!actor@hplabs.hp.com (Clif Swinford) Subject: Re: More than 16K on a 600XL? To: info-atari8@score.stanford.edu The store where I work sells a memroy expansion board for the 600XL for $40. It works well, but has no casing, so it's not suitable for use in an area where small children would have access to it. If you can't find one elsewere, call (503) 223-6380.

It was written in ACTION! and compiled with the run-time libraries, therefore the ACTION! cartridge is not necessary to run this program. I am unable to distribute the source code at this time as the code for the 80 column driver is copyrighted. The program emulates 80 columns by using the Graphics 8 mode. I find the font quite readable, more so than some other 80 column emulations I have seen. To use it I suggest you have either a monochrome monitor or a good B/W TV set. It is all but unreadable on a color set due to artifacting. The program has been tested on a 130XE using Atari DOS 2.0, 2.5 and SpartDOS 3.2 under both the XE/XL OS and the old 800 OS (version B) loaded in from a Translator disk. If you experience any compatibility problems please let me know. Vt52em supports a subset of the vt52 terminal capabilities. These include cursor positioning, most of the edit and erase funtions (insert line and delete line, erase to end of line, etc., etc.), and inverse video (standout mode). Some things it does not support are blinking and half-intensity text, graphics mode, and status/25th lines. It also does not support hard tabs or a DEL/Rubout key (ascii 127). These are slated for a future release. IF connected to a Unix/Xenix system do an 'stty -tabs' to have all tabs converted to spaces (soft tabs). The program also does not include any form of file transfer. I wrote it primarily as a means to use Unix/Xenix programs requiring terminal emulation. Included below is a Unix termcap entry that will supplement the standard vt52 entry and take advantage of the added features of vt52em: a1|atari|atari vt52em:\ :am:al=\EL:dl=\EM:so=\Ep:se=\Eq:tc=vt52: If using an Atari DOS (2.0 or 2.5) you must pre-append the program to an RS232 loader, rename it AUTORUN.SYS, and boot the disk with Basic disabled. With SpartaDOS you may run it from the command line as long as the RS232 handler has already been loaded in. Using the Program After booting the program, and passing the title screen, you are placed in a command mode. Typing a '?' followed by RETURN will display a list of all the commands and their usage. Most of the commands should be self explanatory. The program implements control-S/Q flow control to prevent buffer overflow at bauds of 1200 and 2400 (screen writing in Graphics 8 is SLOW, about 1200 baud max). This feature may be turned off or the start and stop characters may be changed if the system you are on uses different ones. Pressing when in command mode will put you in Terminal mode. Pressing
