18f252 tait programmer
For most HEPAX functions there are alternatives anyway. I have come to the conclusion that is is almost impossible to support, and I suggest to forget HEPAX, although it is a great module. I have studied HEPAX intensively during the last couple of days to enable support for it in my MLDL2000. Message #5 Posted by Meindert Kuipers on, 10:00 a.m.,

Hope this helps to clarify some aspects of the Clonix proyect.

The most relevant of them being the possibility of repairing/substituting a 41 OS ROM's with a properly programmed PIC, the last is only applicable to Fullnut machines though. Some *very* special applications have not been discussed as they are not intended for the common use. Some intermediate versions may arise in the meantime. The Clonix41_man1.doc is, obviously, a draft, the definitive edition will be (hopefully) ready in a couple of weeks. I'm also waiting for this as the only way to find out if there's something to change/improve in the proyect. It should also be advisable for you all to wait for those first impression from my (un)volunteers beta testers, to form a better picture of the whole thing before making a decision. I've already sent the very first three Clonix modules to the main proyect contributors, hope they receive them in short and send their feedback. If you don't want to face this task, send your JDM programmer along with your housing module and I'll do it for you. They can usually be found in many electronic components stores as well as at eBay (search for "18f252" including descriptions) they go for $10 - 15.Ĭhanging the 5.1v Zener for a 5.6v rated one is highly advisable. Almost *any* PIC programmer is suitable for the task, IMHO the simpler the better: JDM programer schematic (public domain) is attached along with the Clonix info into the Hardware folder if you want to face a small DIY proyect. A 41 edge -> DIL adapter will go along with every module, this is needed to connect the module to the PIC programmer and(re)program or read the Clonix. Early machines as well as 2x (1.7x in fact) speed up 41's are fully supported.

c)HEPAX rom can be emulated though, but it needs a specific code which isn't fully tested yet and d) HEPAX rom *without* its RAM file system is (to my mind) of little interest. Actually it can handle ENBANK3 & 4 also, but I've decided to supress this feature from the PIC code because a) only HEPAX use it. So it's up to you to decide how much they're worth :-) Have No Idea (literally) about pricing, first units will run its own luck at this very site (FSOBO) or eBay (I'm still regarding pros and cons of both options). As for now I have only got tree spare shells. A reasonable rebate will apply for those that can send one or more spare modules. Currently (and I've got no solution for that in the short) an empty or useless module is needed to built the Clonix in. The first Clonix modules will be ready to ship by Xmas time. Particular questions will be answered in detail by direct mail also. Now I'm going to (ab-)use David's site hospitality and try to shed some light regarding common questions that some of you have sent me by mail. Thanks for both your compliment words and, of course, the (promissed) beers -) Don't forget to save some pints for John Ioannidis! His original code has been a "solid" root to grow my Clonix proyect form.

But one beer you'll get if we meet here: Message #2 Posted by Mike (Stgt) on, 5:34 a.m., I bet for sure you can find it on your own. This is to let you know that the Clonix-41 is alive, and the related (preliminary) info is on-line. Message #1 Posted by Diego Diaz on, 5:23 p.m. Vcc -> External power supply and Dc/Dc converter, or Jdm schematic to obtain voltage necessary for programming mode.HP-41 Clonix module. So, you must do a comprmise of this characteristics to have good programming requierements.Įxample for Jdm compactible Prog : ( you must use rs232 signal converter : max232, 233, or level shifter with transistors, or more simply, resistors and diodes. Look the EEPROM Memory Programming Specification of this devices, from microchip ->Īnd design your own programmer, why not, you must connect PGC ( programming Clock ) PGD ( Programming Data ), PGM ( Lvp enable ), Mclr ( Reset ) Vcc and Gnd ( Power supply ) to your programmer, and respect ac/dc and timing characteristics requierement for programming for these two devices.
