  1. This board has been taken. Stand by as I'll have a few more of these available as time allows. Haven't setup a P-Box yet to start testing what shape the Geneves are in.
  2. Have been trying to organize the TI/Geneve stuff I still have here and came across some MYARC FDC and Geneve boards. Of course as far as I can tell so far these boards are not working boards. I did spend some time today with what looked to be an FDC just like it came from MYARC. After playing with it for a while I found the 74LS245 was fried and replaced it with a new one. This got me to the system being locked up with a cyan screen when I powered up the TI. After about 4 hours and a new PAL and EPROM updated to version 1.5 and a new 70 nano second RAM chip just for heck of it the card is as you see it in the image and working very nicely with 5.25 disks and I'm guessing will work just as well with 3.5 disks but I don't have 3.5 drives hooked up to my TI repair system. Now that the card is working I'm thinking it should have both original electrolytic capacitors replaced. If anyone is interested in this FDC I'm asking $150.00 + shipping. Contact me here privately if interested.
  3. Hi Everyone, I finally got the chance to get the Hidden Reef hardware running again and the system seems to be working as it should. Still working dawn to dark on the real job but hopefully I will complete the TIPI installation soon as well. Enjoy! The Hidden Reef BBS 718-448-9402
  4. Thanks acadiel, I'll contact you once I'm certain exactly what is broken as it could be the AC pwr supply but I haven't checked anything with my meter yet.
  5. Hi All, just wanted to let Hidden Reef callers know that thanks to my power company, Consolidated Edison, browning me out again this summer I seem to have lost another console power supply. Of course I'm now leaving for work 4:30am and getting home after dark so it may be Sunday before I get a chance to get the Hidden Reef hardware back up and running again. I will reply here when the system is up ready for log-ins.
  6. Hi All, finally just about ready to add the TIPI card to the Hidden Reef BBS P-Box for mass storage of the Up/Down load section. During the process of getting this change going I came across a handy little reference board for the 40 pin connector of the Raspberry PI 3B+ at >adafruit.com<. Might be a neat little item to have laying on the bench for those that do much playing around with the Rasberry.
  7. The joys of being a SYSOP. I found the Hidden Reef, a BBS that never crashes, unresponsive today due to flaky IDE operation. So now the up/down load section is not available until I get the parts together and install SCSI to run the up/down loads available again. SYSOPs have all the fun. :)
  8. Rave 99 was one of the companies I got the rights to when I bought out Cecure. I have one of the Rave 99 P-Boxes that actually works. I might have an owners manual but I'm not sure why anyone would want one since any boards used with it needed their power supplies removed from them. This caused much confusion in the community and countless MYARC, CorComp and TI boards were ruined when those boards were removed from the Rave 99 P-Box and installed into TI P-Boxes. As far as I know there are no existing drawings and/or manuals available for the Rave 99 P-Box.
  9. I seem to recall being told by someone who knew way more about ttl logic than I that the TMS9901 is a chip that actually "wears out" over time. Hard for me to understand how something with no "moving parts" can wear out but when I think about cards that use the TMS9901, the CorComp RS232 for instance, I believe it.

    OPA Gary!

    I remember the last time I was typing with him when he got a Geneve setup from me he was typing about the "RoHS" standard and how much reflow work he was doing for Atari/Nintendo.
  11. All EPROM versions prior to 1.6 may or may not work but are more likely to work using the Geneve than the 99/4a. The 1.6 EPROM should not be used without the complete upgrade which requires different hardware modding for each card in the series.
  12. I think I explained the WHT SCSI controller history here on AA in an SCSI thread a while back so a search for the long version of the history can be found if needed. Here's the short version on the WHT SCSI controller series history. I was the authorized WHT repair/upgrade station here in the USA until Competition Computer bought the rights for the WHT SCSI series "E", "F" and "G" boards. At that point Don requested I ship all remaining boards/chips I had to him and he shipped that inventory to Competition Computer as part of the sale. At this point any upgrades/runs of boards will need the permission of Competition Computer. Although many of the original "E", "F" and "G" cards did function on the Geneve most did not on the 99/4a. The 1.6 upgrade gave all three card verisons very stable operation characteristics with all available popular hard drives including ZIP and Syquest EZ-135 units. Hope this helps.
  13. Just for giggles shift338 do you have the correct orientation with the three resistor packs at location R1, R2 and R3?
