Videx Ultraterm Driver

We've just completed a Videx Ultraterm display driver for S-C Macro Assembler Version 2.0, so now you fine-print fans can use the assembler with that card's high-density modes.  (My favorite is the 48 x 80 inverse mode.)  As with the other Version 2.0 drivers, complete source code is supplied so you can tailor the card's performance to your tastes.

This driver is included on all Version 2.0 disks after number 1274.  Those of you with lower serial numbers can return your original disk for updating.  Please include $1.00 to cover postage and handling.  We have also corrected several minor assembler bugs in the last month, so those of you with serial numbers below 1252 might want to update your disks as well.


Quarterly Disk #18

I'd also like to remind you that AAL Quarterly Disk #18 is now ready.  This disk contains all of the source code from the January through March '85 issues, including the final install- ments of DP18 and this month's 65816 disassembler.  That's many hours' worth of typing saved, at a cost of only $15.  Remember that we also sell a year's subscription to the Quarterly disks for only $45.  That's four disks for the price of three!
