  1. You can also just use almost any 3-1/2 drive as DSK2 to test with. Just cover the 2nd hole on the floppy with tape then format the disk. Use a straight through standard cable to the drive.
  2. Sorry humeur, I don't have any SCSI cards to get them from.
  3. Yes I agree, but someone with one has to do it.

I wrote a GAL with input 8 LOW and it does not detect any drives.
  7. Yes TY Jim, I will be going back over these files again and have repaired the TI RS232 files. Many I have done have multiple conditions\patterns that I have seen. This is why I NEED testers before we post these files. I have also added the 2 Triple Tech PAL's to the list.
  8. Yes I see what you are saying, but no...I'm not looking at AND's, OR's or any of that. I'm simply cycling the inputs to get an output pin to go low and write down the each input switch position. I'm not compiling anything, just entering them into the PAL.jed file as 0's and 1's. Then converting them to GAL.jed with PALTOGAL.exe to write them to 16V8 chip. Not a very Hi-Tech way of doing this...but it seems to work. LOL
  9. mizapf, I'm not exactly sure what you mean by equations. All I'm doing is creating patterns/sequences for the output pins from the inputs.
  10. Yeah NP RickyDean, when I get them all retested I'll release them all here.
  11. Hey all, I am in need of some PAL\GAL chip testers. I have manually decoded the following PAL's: PAL12L6 map files for GAL16V8 chips ------------------------------------------ Corcomp_DSDD_FDC_U1_PAL.JED Corcomp_DSDD_FDC_U2_PAL.JED Corcomp_MES_Lower_U2_(LB1A)_w-o FDC_PAL.JED Corcomp_MES_Lower_U2_(LB1A)_w-FDC_PAL.JED Corcomp_MES_Upper_U10_(UB2B)_w-FDC_PAL.JED Corcomp_RS232_(REV-F)_U8_PAL.JED Myarc_MEXP-1_32K-128K-512K_PAL.JED TI_PHP1220_RS232_PAL.JED TI_PHP1240_FDC_PAL.JED TI_PHP1260_32K_PAL.JED TI_PHP1270_P-CODE_PAL.JED PAL16L8 map files for GAL16V8 chips ------------------------------------------ Corcomp_MES_Upper_U9_(UB1A)_w-FDC_PAL.JED Corcomp_Triple_Tech_U7_(2CLKA)_PAL.JED Corcomp_Triple_Tech_U23_(2-3TA)_PAL.JED PAL16R4 map files for GAL16V8 chips ------------------------------------------ Corcomp_MES_Upper_U11_w-FDC_(UB3A)_PAL.JED What I need is people that can program these into some GAL16V8-25LP chips and install them on boards to test. I have tested all them on my boards successfully but would like more board testing. I have both the PAL and GAL converted files. Please PM me if you can test any of these.
  12. Try this one, although the ADVLAND does work correctly. The only file I see as 'ADVENTUR' is the module files to work from extended basic. ie: ADVENTURE, ADVENTUR_1 and ADVENTUR_2. And yes all the files in that zip file on here were v9t9 files, except for LAKESAN which I created on real iron last year. ADV01.zip
  13. Does anyone have a version of 'Super Disk Manager v4.0' that can be burned to a eprom to use on a cart board like a Red Board. I would like to have it as a single cart like 'Disk manager 2'. I have only found a grom version 'Super Disk Manager v4.0 (1984)(99-4A Users Group).G.BIN' and and a Gram Kracker dump. Or can these be converted to that? It is on my Finalgrom cart but would like it as a separate cartridge.
  14. I also have a Corcomp fdc story, I have 3 corcomp fdc's(2 are mine and 1 is a friends) with the 2793 chips. I purchaced both about 5-6 yrs ago and both controllers didn't work correctly, they had inconsistant/flaky operation, error 16, 'not initialized' messages. Both would not read/write/format DD disks. They would sometimes read/write SD disks but were inconsistant. I tried to repair one of them about 3 yrs ago by cleaning terminals, testing voltages, replacing the ele. capacitors, swapping the socketed chips...with no improvement. Then just put them aside and moved on to other projects. Reading this topic got me thinking about these cards again, so I broke one out. Started testing again and adjusting the 50k and 10k var. resistors again with no improvement, so I reset them back. I then went to the var. capacitor and adjusted it with no improvement again. I looked very closely and saw slight green funk in\under the capacitor, on the schematic it shows a fixed 10pf & var. 4-60pf capacitors on that circuit for a total of 14~74pf. Not having any variable capacitors, I just clipped on a 22pf cap(across either capacitor) for a total of 32pf and the card came to life. It formatted/reads/writes DD and SD disks with '0' failures. I let it run for about a week cycling on and off, tested with diff. drives and disks again with '0' failures. So I broke out my 2nd controller, removed the cover and simply clipped on the same 22pf cap. and turned it on...0(zero) failures! I tested it like the other one for about 3 days reading, writing, formatting with no failures. So I got a hold of the 3rd card and we did the same thing, clipped on the 22pf cap. On first test it was a little lazy and said 'not initialized' once, then after about 30 seconds it began to read/write correctly. I swapped it with a 27pf cap. and it began to work flawlessly, I kept the card for about a week testing cold startup and long runs, '0' failures ever since. I ordered some variable caps(5-50pf) and replaced them now all 3 cards work. Maybe this will help someone else.
