PAL/GAL Jedec map files for TI, Corcomp, Myarc

+Ksarul · November 2, 2020

I'll try and go through all of these tomorrow. Yes--there are some interesting differences that make sense to be opposite (I think TI was taking a signal that was considered to be a normal low and inverting it to get a high input)

This matches the new JEDEC equations for the 32K card.

Not at all. The JEDEC file from the reverse-engineered PAL matches the TI equation set you posted. I saw no differences, so his new equation set is good.

I am looking to repair the revision E and F SCSI cards for programming the GAL 16v8 and MACH211 if you have the jedec files, or any other documents such as diagrams.

Thank

@Ksarul has several prototypes - we just need very clear pictures of where the PAL lines go. I think I posted some previously, but they were older pictures and not too clear. https://atariage.com/forums/topic/306514-hexbus-jedimatt-compatible-sidecar/?do=findComment&comment=4531730

Here's the chips on board:

74LS259

74LS251

74LS74

1052911-X (TI Hexbus chip - @Ksarul has tons)

F4049BPC - Not sure. Appears to be a Fairchild chip.

2532JL - 4K DSR (we have a dump)

PAL12L6 - the PAL

humeur · November 3, 2020

F4049BPC a same to MC 4049

MC14049UB - Hex Buffers.

Yes, please download all 3 zip files again, these are the latest...but some files are the same as before,

just changed the dates to keep track of the files.

Also the Corcomp DSDD files U1&U2 are for the controller with the WD2793 chip. The zip has been updated.

Here's the specs on your F4049BPC compliments of 1975 Fairchild Handbook.

I also have several tubes of the 1052911-X if somebody is doing a group project.

+Ksarul · April 4, 2021

Thanks for the datasheet, Doug. I have a bunch (at least 200) of the 1052911-X chips too, so we definitely have enough of them in the community to support a project using them. . .

+helocast · April 4, 2021

No problem, Ksarul. I probably should've just posted the whole clean 516-page PDF

for anybody else researching chips of the era (it's a huge one):

Fairchild_MOS_CCD_Data_Book (1975).pdf

Fritz442 · December 25, 2022

Merry Christmas everyone, I just added the Corcomp DSDD FDC w-1773 controller chip to the repository at the top.

Edited December 25, 2022 by Fritz442

Artoj · December 28, 2022

As I have never used PAL/GAL chips, I do understand basically how they work. If anyone could do a binary input to binary output matrix, it would make it easy to use standard logic chips to replace them. Merry Christmas regards Arto.

+dhe · December 29, 2022

My Favorite Data book - Got to love the PAL illustrations!

1981_MMI_PAL_Handbook_2ed.pdf

Artoj · January 3

I guess I will be writing a program that will convert PAL/GAL data to Binary IN/OUT and create a visual table for reference, then possibly a Logic tree to complete the crossover to standard logic chips. Already half way there, thanks to the DATA book uploaded by dhe. Regards Arto.
