  1. Agreed, but consistency between glyphs is important all the same. I can get pretty reasonable results all the same, and have perfectly parallel lines, perfectly consistent stem and stroke (even with curves!), etc. Regenerating 2D and 3D data from old hand-drawn blueprints was one of my prior careers you see... (Also, reverse-flatpattern derivation.)
  2. Dassault CATIA is my CAD of choice-- It is internally BSpline (and or NURBS) based, and is VERY precise. It has several useful tools for manipulating spline curves, such as the "affinity" tool. (It lets you input a 32 bit precision floating point value, to precisely bias a curve according to an axis system-- User definable.) Instead of "control nodes" on bsplines, it uses a 32bit "tension" value for tangent lines. (DWG is a terrible format btw. It uses quadratic curves instead of bsplines, and has a nasty habit of turning splines into polylines. Nasty nasty nasty.) I usually use 2d IGES for 2d data exchange with CAD software for this reason.
  3. I prefer my CAD software for that, because I can use actual measurement constraints to assure the geometry of the curves is mathematically perfect. I can save it in a suitable format, then convert it to .AI with something like PStoEdit. I can assure that the curves are EXACTLY where I want them in the glyph's EM space, I can make sure that the stem widths are EXACTLY the right spacing, that the tops of letters and the depths of descenders are EXACTLY right, etc. (this obsession with mathematical perfection is important, because of how truetype fonts do hinting instructions. Without that kind of perfection, you are gonna be working yourself to death making sane hint instructions for the different point sizes.) Illustrator kinda just wings it. The file format is useful as an import intermediary, but I prefer exact geometry.
  4. Ironically, I keep a Yahoo mail account explicitly for all those sites that demand an email for nebulously defined reasons, exclusively so it can service as a trash bin for all that unsolicited email.
  5. The idea is to use a more modern SRAM. Much of the space is taken up by the sram modules, but there are more dense modules to be had these days. I was thinking more along the lines of a TSOP socket on a solderable DIP. Price would go WAAAY up, but still. Failing that, go ahead and just use tsop packages with SMT mounting like they are intended.
  6. Hmmm... Outside the box solution: One of these inexpensive backplanes... https://www.mouser.com/ProductDetail/Advantech/PCA-6105P3-5A1E?qs=HovGnFcXeQCTm1XmLEYbdw%3D%3D With one of these SBCs (which has an FDC!) https://www.bsicomputer.com/products/wsb-h610-full-size-cpu-card-2864 That would give you a modern class computer with a real floppy disk controller. It would also give you some ISA slots for whatever you might want to put in there. You would need a special chassis though.
  7. OK, another "Wish I had..." Option. 44pin interface (EG, after a JediMatt 32k card and Tipi) SAMS. (I can envision how SAMS can be expanded even bigger in a more or less back compatible fashion*) Not all of us have the desk real-estate for a PEB, nor do they want one. * Basically, you put a better mapper on, with an opaque latch driven by the data bus in addition to the CRU bus SAMS currently uses. You do this by marking a small slice of RAM as reserved for the banking register, and do the writes there. When the correct address lines (for that location) and WE are hot, the data bus latch enables and catches the data written to control the mapper. Each additional bit gained exponentially increases the banking space. Since switching can still happen in the original SAMS methodology without the special writes being done, it would be back compatible. Just if you do the special write, you basically "Bank out the set of banks". At least from a logical perspective anyway. 8 bits of additional latch should bring the theoretical max banked memory up from 1mb to 256mb.
  8. I was planning on doing this very thing in the near to distant future. (Still waiting on shipment of the adapter.) 2 DB9 female, 1 DB9 male, and a 5vDC barrel connector, on a protoboard, in a 3D print shell. Bob's your uncle.
  9. While drawing a title screen prototype for FarmerPotato's upcomming title, I noticed that with it shrunk real small, it looks real sharp. This made me have a strange idea, when I considered the FPGA Ti 99 project cited in the develpment subforum... Small Ti 99 handheld. (think about the size of the original gameboy, but a little fatter in the 'depth' direction, so full size carts can go in.) There are tiny vga (and composite) screens you can source for such a thing. It would make a neat project I think. You said the most radical, so there you go.
  10. DS, 2DS, or 3DS? (and which revision of the console) Ninty does not like the flashcarts. There are multiple devices, for multiple generations of the handheld.
  11. How about amazon? https://www.amazon.com/Panasonic-LS120-Beige-Bezel-LKM-F433-102/dp/B0045JPK7K/ref=sr_1_50?keywords=LS120&qid=1571056034&sr=8-50 Or NewEgg? https://www.newegg.com/p/2M6-000V-00004?Description=LS120&cm_re=LS120-_-9SIAA7W8VH8393-_-Product EDIT I also found this, concerning your TEAC SCSI units. https://hxc2001.com/download/datasheet/floppy/thirdparty/Teac/FC1/HW_HS_1100.PDF It appears to be a very detailed user manual for the scsi controller and disk combination you have, and includes the jumper info. On Pg11, it discusses the various formats of disk the drive and controller supports, and what "mode" to use. For high density diskettes, this would be the "2mb" mode. They are clearly referring to "unformatted capacity" for size. Their table lists 1.20mb, 1.44mb, and 1.62mb formats in this configuration category. (I suspect that the 1.72 variant of the microsoft distribution formatting is not supported?) Jumper configuration information begins on Pg42. It looks like the controller expects to be told what kind of floppy is inserted or something. (PG40) There are two cited methods for getting the drive/controller to identify the disk type as the 2mb variety, and they both seem to involve scsi messages being sent. I am beginning to think that the LS120 is the better option--
  12. The one I got (and have set aside, since it has more snow than a blizzard on a mountain top) is a UM1381. They seem to be quite common. What's so magically special about this TI-900?
  13. That latter is quite interesting. Rather than controlling the speech synth, I think it would be more interesting to EMULATE it. Especially with a Tipi. One of the things I keep reading is how power-hungry a speech sidecar is. If you can avoid having that on the expansion, it makes sense to me...
  14. Basically, Steve Jobs visited XEROX-PARC, and saw the future of computing there. That is why Mac was pushed, and IIgs was sidelined. (the IIgs was a very good computer for its time) http://www.righto.com/2016/06/y-combinators-xerox-alto-restoring.html
  15. I doubt the SRAMs inside could stand up to the ionizing radiation of the 3 month trip (best time) to get there... BUT-- the TI does have a reasonable power footprint (once you cut out that sinfully inefficient transformer)... I wonder if my "Nuclear powered laptop" idea would work... (Not really as scary as it sounds. Just a bunch of tritium gas containing sign illuminators and high efficiency PV cells.)
