  2. Incidentally, if anyone would like to try my 1986 ZX Spectrum conversion of this game, it's available to play online at the archive.org: https://archive.org/details/zx_Planet_Proton_1986_Your_Sinclair
  3. Thanks for this. It plays almost identically to my ZX Spectrum version; though mine has graphical improvements granted by the higher screen-resolution. I THOUGHT I'd played it on a Ti-99/4a back on the day, but it WAS over 30 years ago! Maybe it WAS the Vic-20 game I'd played (though someone on the Ti-99/4a section seems to remember a similar game on the Ti). I'm not sure if it was a type-in or not on the Ti; though again, my memory isn't what it used to be!
  4. Your link didn't work. I take it this page, relating to the UK1541 is where you intended to send us? http://www.indieretronews.com/2015/01/uk1541-latest-c64c128-product-but-is-it.html Looks interesting but the developer comes across as arrogant, branding it as an "Ultimate Killer".
  5. To be honest, I've only ever "SAVE"d to tape. I have few tape programs for it (being 4K). Most of the cassettes I have, contain more areas without Ferric Oxide than with. At the time I bought it (about 5 years ago), mine was only one of two known to exist and the only one known to be in working order by the users "in the know" within the TRS-80 Google newsgroup. I was asked to create a dump of the ROMs in order to verify them against a set of ROMs dumped from the other machine. As mine still works and still has its original warranty seal intact, I was set against opening the machine and pulling the ROMs but was told that if I switched on from cold and then immediately typed "SAVE", the micro would dump its entire memory to tape. I recorded the dump as a WAV file; direct to a digital recorder and ran the resulting file through a program I'd been sent which extracted then CRC-checked the ROM from within the WAV file. This was then compared with the NTSC version of the ROM and verified as byte-for-byte identical. Apparently, there are no differences in the ROM code between NTSC and PAL machines. As you mentioned, Operating at 50Hz may make a difference to its operation, but I've been unable to verify this.
  6. They were. I own a UK Model III, Level I with 4K. Tape-only for me.
  7. Pronouncing Sysop as anything other than "Siss-Op" is like pronouncing ZX (as in Spectrum) "Zee-Ex" instead of "Zed-Ex". Ugh!
  8. Depending on what you plan to place in there? There's not a lot of room. Bear in mind the 1541 had its own 6502 CPU on a circuit-board which stretches the entire length of the drive. All the circuitry is above the floppy-drive. I have a couple of these if you need internal photos but don't expect to be able to squeeze much in there. Honest!
  9. Jet Set Willy. Biased, I know but it's a great pick-up and play game as well as a fantastic, accurate conversion of the ZX original.
  10. Hey, Atarileaf, has our friend Mark run out of NOS/Refurbished Coco3s yet? I was lucky enough to grab one about 3 years ago, pre-fitted with 512K and a SuperIDE. The price wasn't bad for (what was effectively) a new micro but postage and duty on its arrival in the UK sullied the experience somewhat. I figured I'd go with an NTSC model due to the PAL ones suffering from loss of colour (UK spelling) when playing games which rely on the popular use of artefacting to boost the number of available colours. UK/PAL Cocos often played these same, colour-enhanced games with monochrome, blocky graphics due to their inability to replicate NTSC artefacts.
  11. I put one together a few months ago. It's a really nice board. Here's my build. http://atariage.com/forums/topic/232781-building-a-supercart-from-arcade-shopper-pcb/?p=3133707
  12. With these types of spring, I've found that if you use snips to cut-off the ring at one end, then insert a hobby-knife a couple of loops in, you can bend up the coils to 90 degrees to make a new loop. The trick is finding one of similar tension to the original. I've fixed a TRS-80 Deluxe joystick using this method. The joystick is a little stiffer than it used to be but works better than it has in ages!
  13. Mine is a Model III, Level 1 with 4K (not 64K) on the raised silver sticker. Would that do?
  14. I think you may have mis-read my post. I never said the OP's picture showed a C64G. I've highlighted the part of my post you may have misunderstood. Please read my posts PROPERLY before "correcting" me in future. Thank you.
  15. The images definitely work. As Imperious says, the cart images require 32K to run. Either a PEB or nanoPEB is needed. Assuming you have 32K, try "inverting" the image before burning it to EPROM. User RasmusM released a Java-based ROM bank-inverter. If I find a Ti ROM image which doesn't work I find inverting it usually gets it going. Ramsus' Bank-inverter tool can be found in this very thread here: http://atariage.com/forums/topic/193163-512k-cartridge-status/page-16?do=findComment&comment=3025762
