    An unusual Apple IIe that has the platinum colouring but no number pad. Turns out it's an unusual International Platinum IIe. It's now souped-up with a CFFA3000, Titan Accelerator IIe, VGA Scaler and Mockingboard.

    Atari 800

    From the album: RetroElectroDad Computer Collection

    This Atari 800 arrived with a broken keyboard and would not boot. It now has a new keyboard from Best Electronics and boots after replacing one of the 16K memory banks.

  8. Happy days - picked up an Atari SC1435 monitor for very cheap.

      Excellent - CRT is the only way to properly display these old systems :)

      It will mean I finally have a suitable monitor for my Falcon or STE... if it works! Waiting for an ordered cable to arrive...

  9. I voted for green, because that was the colour the terminals used when I was learning to program on a mainframe and it feels like it screams retro!. But... for each platform it differs for me. For instance DOS PC - amber, Apple ][ - green, TRS-80 - white.
  10. Im so glad its back to you after its stay with me. I didnt notice anything obvious with the reset switch when I was testing it so I hope it wasnt bashed during transit. I tried to protect it from the rigours of international postage. I never did change the battery so thats a wise move! Cheers, Trev
  11. My Amiga with Workbench Amiga 1.3 was outstanding for it's time (haven't used subsequent releases). I was using MS-DOS 3 at work and wondering why everybody didn't go Amiga. Somebody at work had a Mac 128K to evaluate and it seemed primitive in comparison. MS-DOS 6 was, for me, the best DOS I worked with. Windows 3.1 was OK but 98 seemed more capable and solid to me. Then I moved into the Windows NT world and wasn't greatly impressed until XP which seemed great until I sampled Mac OSX Tiger. These days Windows 7 seems even better now that I've had to 'upgrade' to Windows 10 for work. OSX Snow Leopard was the peak of that line for me, luckily as it's the highest my vintage Macs will reach. If I had to choose two, it would be Snow leopard and Win 7.
  12. Boulder Dash, Lords of Midnight, Star Raiders, Gridrunner and Impossible Mission would be five feasible titles I'd like to see from a variety of platforms. None of which would've happened back in the TI's heyday but now with memory upgrades and large carts are very achievable.
  13. Please put me down for an Odyssey 2 extension when they become available. Great work!
  14. In September 1982 I bought my first computer, a Sinclair ZX81, then a couple of weeks later the very necessary though unreliable 16K RAM pack. The first magazine listing I remember typing in was a Star Trek game in the UK magazine Personal Computer World (Octobet '82). I vividly remember spending all evening over it and I loved it. I was very reticent about switching the machine off in case it didn't reload but I think the cassette save was OK in this case. I have looked for that very magazine issue for a few years now but until three weeks ago it had not appeared on eBay as far as I could tell, but now I have it! I plan on reliving that evening soon and once again typing that Star Trek game into my ZX81. I have not even found the game saved online so I think the effort is justified. I'll save it to SD card this time!
  15. You've been very successful this year! I'm trying to ease off a bit but it's a hard habit to break. I'm in a similar situation with the size of collection and have run out of space.
  16. This year:- TRS-80 Model I original model without the keypad but upgraded to level II BASIC, fully working. Best pickup of the year so far. ZX Spectrum +3 that was 'untested' but turned out just to need a new disc drive belt and is now fully working. Amstrad 8256 CP/M machine, beloved by authors, rescued from recycling for free and I don't yet know whether it works but it is in some state. Dragon 32 fully working. Dragon 32 in a bit of a state but served as a motherboard donor for a broken machine. Atari 1040 STe with colour monitor both fully working.
  17. Did you get anywhere with running the code? I do have an Atom though it spends most of its time in a box and I haven't used it much. In case it helps, I looked up running machine language code in Atomic Theory and Practice and there were the following commands:- LINK - link to machine code subroutine (returns with RTS, A,X and Y are initialised to the same-named BASIC variables and decimal mode flag is cleared) e.g. LINK #FFE3 *RUN - load and run a machine code file, e.g. *RUN "FILENAME" SSS where "SSSS" is an optional load address. The execution address is as stored in the file even if you relocate it. *LOAD - load a named file, optionally relocated, e.g. *LOAD "FILENAME" SSSS where "SSSS" is again the optional relocated load address.
  18. I don't think the online shop puts it up until it is in newsagents - I get it through subscription usually a few days earlier than shops have it. It's issue 142.
  19. Arrived this morning - 6 pages! I was surprised. The article covers the TI-99/4 and 4a life story with side boxes on publishers and peripherals. Way more than I was expecting.
  20. I'd hazard a guess that it will be in the "Minority Report" section - it could be two double pages worth, one on hardware and one on the pick of the software. I hope they include some of the newer homebrew titles as they're way above the standard of the vast majority of the back-in-the-day releases.
  21. My rarest according to Atarimania are both 8s - Omnitrend's Universe and Alternate Reality: The Dungeon.
  22. It's a nice machine! I didn't realise until I owned one how close it was to the MSX / Memotech - using the same graphics as the TI. One thing that hadn't occurred to me at first when I started collecting is that I'm going to have to develop some electronics skill to repair, recap etc these old machines as they deteriorate. I had to change the motherboards in my two Mac LCs and made my Spectrum 48Ks composite video but that's my limit right now. I think I've shown most of my machines working on Instagram by now.
  23. It's a sickness for me. Started with my 800XL with 2x1050 drives, 600XL, Amiga 500, NTSC SNES, Japanese Mega Drive that I bought new. Then it was buying any new console from Dreamcast onwards. Then it was buying up machines I had parted with - TI-99/4a, Sinclair ZX81 and Acetronic MPU1000. Then it was 'always wanted a VCS'. From that point on it's been a matter of collecting every computer I'd ever read or knew of and any console. As has been pointed out, I couldn't possibly find time to use them all, but from the top of my head the current inventory of retro computers not including various drives, monitors, flash storage units etc contains:- Acorn Atom, Electron, BBC Model B x2, Archimedes A3000 Amstrad CPC6128 Apple IIe x2, Mac LC II, Mac LCIII Atari 400, 800, NTSC 1200XL, 600XL, 800XL x3, 65XE, 130XE, 520ST x2, 1040ST, Falcon 040 Commodore VIC-20, 64 x2, 64C, SX-64, Amiga 500, Amiga 500 Plus, Amiga 4000 Dragon 32 EACA Colour Genie Mattel Aquarius Memotech MTX-512 Oric 16K, 48K, Atmos Philips MSX2 Sam Coupe Sharp MZ-700 Sinclair Zx81 x3, Spectrum 48K x3, Spectrum 128, Spectrum +2, QL Sord M5 Tandy Color Computer Texas TI-99/4a x3 (1 PEB) Toshiba HX-10 MSX x2 Yamaha CX-M5 MSX x2 As for the ones I use most.... an expanded 800XL, TI-99/4a with CF7A+ and Amiga 4000 are set up most of the time. The others are boxed up along with most consoles. Space is now an issue.
  24. Well, seeing as it's bumped...... 1. Opening up my unexpanded 600XL when I bought it after selling my TI-99/4a. The TI had to go even though I loved it mainly because it was a very closed system having no access to machine language. I was intrigued by the mysterious “peek” and “poke” commands I saw in listings for other platforms. The 600XL was upgraded by a 1064 a few short months later at Christmas - on my first trip to buy software for my Atari i bought Airstrike II by English Software at WH Smith in Newcastle Upon Tyne. I could only play the 16K version so couldn’t wait to get more memory and try the other side of the cassette. 2. Finding another Atari user at university and buying his 1050 disk drive with many disks of “backups”. My only brush with pirate copies from “the scene”. I went to his place to buy it carrying two boxes of blank disks and all were filled when I left. 3. Discovering RPGs with Alternate Reality - The Dungeon. I ended up playing this through three times. The packaging was beautiful and I’m so glad this is one that I bought and still have to this day. I was hooked on RPGs from that time and went on to finish Wizard’s Crown, Eternal Dagger, Ultimas III and IV before I moved on to the Amiga. 4. Many many hours spent with Synassembler and a black-and-white TV trying to be a games programmer. I was at one stage offered a conversion contract by Zeppelin (who were nearby) but I wasn’t allowed to enter into a subcontract agreement as a term of the government program I was on. That was disappointing! 5. Getting my Symbolism game onto a Page 6 special disk. I now know how much better it could have been but I was young and inexperienced! 6. Buying a Dixons 800XL plus 1050 drive package when they were really selling them off cheap. That 800XL became my main machine and it had a lovely keyboard, the 1050 meant that I now had two drives. What luxury! Shame that I binned the 800XL when it died as I haven’t found an 800XL with as good a keyboard since and if it happened now I’d hope to repair it. 7. Receiving the Mapping The Atari book for Christmas. How that book opened up the possibilities and answered all my questions. It was invaluable. 8. The intense shock the first time I encountered the Alien in RoF. It was around 2am, the house was quiet and my heart rate didn’t come back down for quite a while. From that moment the game was filled with a tension for me that had been absent up to that point. 9. Hiring games from a lending library and defeating the copy protection to create my own backups. Particularly copying Koronis Rift on disk and transferring Bounty Bob from cassette to disk (there were quite a few encrypted segments in that multi-load). I was pretty alone in my network as an Atarian so I had no access to pirated copies unlike my Commodore or Spectrum owning friends. 10. “The games are so much faster on the Atari” - a quote from my C64 owning best friend when he played Bruce Lee on my machine.
