ooh, ooh!!! pick me, pick me!! I've got a PEB setup with two shiny brand new floppy drives, a nice DS/DD controller, HDX hooked up, and a vintage PC with omnifloppy raring to go! I'd also love a box of Geneve disks, but am not picky. Disk diving is a lot of fun! I'm 100% in.

Did you find someone to help you out with this? If not, I'd be happy to.

I'd be happy to help out. I'm not sure what the fees are to transfer money or send payments to/from paypal, but as long as they're willing to cover the money transfer fee (if any), I'd be happy to receive the money (at no additional cost ) and launder it on to arcadeshopper via google wallet on your behalf. There's a few folks in the community that can vouch for me.

The zip files located in the Games\Carts directory and the RPK files located in the Games\Carts\RPK directory are CART ROM images that can be used by Mess, V9T9, Classic99 and a few other Emulators. The ROM images contained in these zip and rpk files can also be used on the real hardware using a GRAM device like a PGRAM, PGRAM+ or Gram Kracker device. I think there are also loaders that might load these files without a GRAM device, but I'm not 100% sure about that. Regarding you second question, "could you use these on your nano?", I'm assuming you mean your nano PEB? If that's accurate, then you could unizip the various files and copy the bin files to your nano and then load those using a GRAM device to play on your real hardware. As OLD CS1 mentioned previously, the file is in the RAR format and can be unrar'd using 7-Zip (as he mentioned) or WinRAR etc..

While this listing is for an Amiga, I just had to share this link. Check our the sellers description, it is priceless! I wish Vegas was selling odds on this listing! http://bit.ly/NuhRNa

I was having all kinds of trouble with the multiupload link; mostly to do with my firewall software and content filtering software complaining of malware on the site and all kinds of non-sense. I finally fired up a VPN and hit the link, however I found that most of the links were dead, but finally had success with uppit. That said, I went ahead and uploaded the file to my Dropbox and thought I'd just share the link for future ease of downloading this version. Here's where I put it: https://www.dropbox.com/s/7ei2ejswxlabpnz/TI99-4Av2.rar?m= And thanks for all the effort you put into maintaining this fantastic database!!

Can anyone tell me where can I find the latest download / release of Gamebase? It looks like the links are a little old and appear to no longer be working. At least not for me anyway. I appreciate it!! Never mind!! Found it. Odd that the forum search didn't turn it up for me. http://atariage.com/forums/topic/220038-gamebase-ti994a-version-21/?p=2891834

I'm in for 2 kits for me and would be most happy to volunteer to build out kits for those that don't have the equipment or ability.

Happy to loan you mine if you'd like. Not intending to add pressure.

Wow!! The C65 auction ended at $7,625.00. Now that is something!!

Like you, I love to keep my software on floppies and code directly on the real thing. That said, the killer app part of HDX is, IMHO, the ability to read and write the same file in Classic99 and on the TI transparently is just super cool and very efficient. I can do power editing on the PC emulator, compile and test on classic99, then load and run on the TI without the overhead of file transfers etc.. Truly cool!

The last I heard, mdude shut it down and moved his store to eBay.

I wanted to confirm that the Winbond W27C512 chips are a great choice! Burned 3 and verified their use with John's v03c 64k board just 2 days ago. Worked great and saves the hassle of using UV to erase. Bump to Tursi for helping me perform the complex math necessary to select the right EEPROM . I forgot that the number in the chip represented the number of K bits not K bytes

That's a great idea. I'll pass that on to Thierry about that and also talk to him about upgrading the database component.

Hey Ciro! If he has a TI RS -232 card and a serial cable let him know that he can download vdm99 from Thierry Nouspikel's site. VDM99 allows you to use the physical drives attached to the PEB via a PC running vdm99. I'll post the links when I get home.

In case some of you don't visit the Y! groups very often, I thought I'd post an update and let everyone know that Thierry has released a new version of VDM99. You can check it out and download it here: http://www.nouspikel.com/ti99/vdm99.htm I really like the program and have found it so much easier to keep my physical disks organized along with my disk images. Here's a quick synopsis: Virtual Disk Manager 99, is a disk manager program that can handle three types of "drives": Files on your PC that contain a TI-99/4A disk image in either DOAD format (i.e. sequential sector dump) or PC99 formats (containing track information). Real drives on a remote TI-99/4A connected to your PC with a serial or parallel cable (this did not work with version 1.0, but was fixed in version 1.1). Emulated drives, inside my Bug99 debugger (you'll need Bug99 version 2.0 or higher). Starting with version 2.0, VDM99 also offers database support: You can "scan" a disk and store the characteristics of the disk and all its files into an MS Access database. You can then browse the database, or query it in various manners to locate a disk or a file, find on which disk a given file resides, etc. Note that the workspace file format changed with version 2, so you cannot reuse workspaces saved with version 1.x. One very important note! You must have the correct version of DAO installed otherwise the program crashes immediately upon launch. You can download the correct DAO setup files from Microsoft here: http://download.microsoft.com/download/vc40std/patch/1/win98/en-us/daoredis.exe All the best!!

So I'm going to expose my ignorance and ask a question. Can you explain what you mean by GPU in the context of this project? I'm not 100% sure I understand what it means to add a GPU to the FA18. I believe a GPU offloads graphics processing from the CPU and allows you to "process" graphics related instructions in parallel with CPU instructions. Perhaps "in parallel" is the wrong term. Maybe independant is a better word. Am I on the right page here? If so, I'm assuming that adding a GPU would allow us to perform some interesting functions like horizontal scrolling or multi-layer scrolling without requiring direct hardware support. I hope I'm warm, because I'm getting pretty excited with possibilities now that I'm thinking about it.

I think I see mine. Isn't it the one 2nd from the left?

No, but I did isolate the problem down to a blown buffer. I just never got around to replacing it. The excitement was in the hunt for the problem. I still intend to replace it, but more exciting projects have taken its place.

If you're looking for help, I'm happy to offer my board assembly and soldering skills to the effort.

I'll move forward on your suggestions and post an update once complete. I'm expecting my EPROM programmer and the Logic Analyzer to arrive in the next day or so. In the meantime, I'll replace the regulators, electrolytic caps, and the 244s and 255. Do the .01uF cap measurements I posted in my last post seem within reason?

I'm looking for suggestions, advice, and mentoring as I try and diagnose and ultimately repair a failed TI floppy controller. Initially it was my only card and was therefore somewhat desperate for a repair, however, a generous TI community member was kind enough to loan me one of theirs so I could be back in operation. I'm now turning this into a learning exercise and would appreciate your thoughtful advice and patience as I ask some potentially revealing and dumb questions. Symptom: The FDC is no longer recognized by the TI. Disk Manager 2 reports disk error 0. Setting CRU bit 0 to 1 via Mini-Memory turns on the LED, however, when I inspect the memory at >4000 it shows 00. Troubleshooting so far: Visual Inspection: Burn marks around the 12V regulator. Everything else looks good - to my eye. Tracing - I've tested continuity throughout the board at all ground points and voltage points. I've traced address lines etc.. So far, I have not located an issue. Voltage Test - I've tested voltage at Vcc for each chip and it that appears to be good - to my knowledge. Resistor and Caps - I've desoldered one lead from each Resistor and Cap and have tested these. I'm not certain about the tolerance for the .01uf caps on the board. Here's the readings for the caps around the buffers: .01uf CAP measurements: 10.57nf, 10.56nf, 9.20nf, 10.38nf, 11.36nf, 11.27nf, 9.52nf, 8.60nf, 11.05nf, 8.99nf, 9.45nf, 9.33nf I'm using an AMPROBE digital meter with the following ratings for capacitance tests: Range Accuracy Resolution 40nF +/- 3%+10 10pF 400nF +/- 2.5%+5 100pF 4uF +/- 2.5%+5 1nF 40uF +/- 2.5%+5 10nF 400uF +/- 5%+10 100nF 4000uF +/- 20%+20 1uF I'm not clear what the +5, +10, +20 number means in the Accuracy column. Can someone help educate me. I've been reading the manual inside and out and don't get it. So that's where I'm at. Any thoughts?
