2110 - Summary/Objective
2111 -
211101 - Follow up ref SDS 3 0000, ref SDS 2 NQ7O.
211102 -
211103 - On 020205 Morris commented that doing the code to increase memory for
211104 - SDS would take a week, and then 6 months to debug. ref SDS 1 Q54L
211106 -  ..
211107 - The other day, Gary submitted a letter to Morris relating recent
211108 - reseach that may contribute to improving memory for Medit. The copy of
211109 - the letter I received says.....
211110 -
211111 -     1.  This is a 16-bit DOS Extender.
211113 -          ..
211114 -     2.  It allows access to 16M memory using RAM only, or to 256M if
211115 -         the virtual memory feature is enabled.
211116 -
211117 -            includes the development tools and two run-time licenses
211118 -            for $375 Additional run-times are normally $25 each.
211119 -            DOS/16M is sold with a full 60-day no-questions-asked
211120 -            return privilege.
211122 -  ..
211123 - Gary's SDS record for today shows planning for the next version of SDS
211124 - and discusses using a DOS extender to improve the current version of
211125 - SDS while the next version is being developed. ref SDS 4 LM5O
211126 -
211127 -              [On 030801 reviewed Gary's planning for a DOS extenter;
211128 -              sent a letter to Morris asking for comments, to follow up
211129 -              Gary's letter today. ref SDS 5 QF91 and ref SDS 5 VL4I
211131 -               ..
211132 -              [On 030803 Morris responds saying a DOS extender could
211133 -              not increase the size of a file used for SDS; this might
211134 -              mean that Medit could handle multiple files under 640K,
211135 -              and that would be a big interim solution. ref SDS 6 B59I
211137 -          ..
211138 -     3.  I have the following notes on converting to DPMI:
211139 -
211140 -            ttp://saturn.spaceports.com/~dosuser/dpmiconv.htm 211142 -          ..
211143 -     4.  If you have a lot of code in compiled form, such as libraries
211144 -         (.LIB or .OBJ files) purchased from third-party vendors (ie.
211145 -         not the compiler makers), or if you use a lot of assembly
211146 -         language, then you'd do best to go for 16-bit DPMI. In this
211147 -         case, you should be able to link the old modules with your
211148 -         program to get a working DPMI executable.
211150 -          ..
211151 -     5.  I recognize that using a 32-bit DOS Extender would entail
211152 -         significant code change, but the above appears to indicate
211153 -         that the usual change to a 16-bit extender is far less
211154 -         painful.
211156 -          ..
211157 -     6.  I have never programmed using a DOS Extender. Does this sound
211158 -         like a plausible thing to attempt? I intend to make certain
211159 -         that I can build Medit (SDS) on my own, and then I will
211160 -         consider whether to try using this or some similar too.
211162 -          ..
211163 -     7.  Thanks,
211164 -

211178 -           I have a 16-bit DOS program written in MASM that could
211179 -           really use an extender.
211181 -            ..
211182 -           Unfortunately, there is no pricing information on your site.
211184 -            ..
211185 -           Could you send me pricing information on your products,
211186 -           please.
211188 -          ..
211189 -     2.  DOS/16M is sold as a package, containing the development
211190 -         tools for 1 developer and and some number of run-time
211191 -         licenses.  The development tools license (the Initial
211192 -         Development Kit (IDK) license) costs $345 per developer.
211193 -         The run-time licenses are $25 each in small quantities.
211195 -          ..
211196 -     3.  We provide two bundles.  The first is for small developers,
211197 -         and includes the development tools and two run-time licenses
211198 -         for $375, normally $395.  It is appropriate for exploration,
211199 -         "one-off" programs, and custom development projects.
211201 -          ..
211202 -     4.  The second bundle includes the development tools and 50 run-
211203 -         time licenses for $1495, normally $1595.  Although this
211204 -         package is large enough to satisfy most folks needs, you
211205 -         may still need to distribute more than 50 copies of your
211206 -         program.  If so, you will need to arrange for additional
211207 -         run-times.
211209 -          ..
211210 -     5.  Additional run-times are normally $25 each, although there
211211 -         are a number of alternative, volume-purchase arrangements.
211212 -         To select the most cost-effective plan suitable for your
211213 -         situation, please send us an estimate of the number of copies
211214 -         to be distributed over each of the next two years, and the
211215 -         revenue you expect to receive per copy.
211217 -          ..
211218 -     6.  Shipping for the development kit is $20 in the United States
211219 -         (for UPS 2-day Air), and $40 otherwise (for Express Mail,
211220 -         which usually takes 2-3 days.)
211222 -          ..
211223 -     7.  DOS/16M is sold with a full 60-day no-questions-asked
211224 -         return privilege.  The guarantee and the exact terms are
211225 -         spelled out in the DOS/16M IDK license, which we can
211226 -         fax to you, if you will send us your fax number and which
211227 -         bundle you are interested in.
