Sega PROMs from Zaxxon (Thanks to Joe Magiera)
One PROM is at board location marked U98 and is a 20-pin device.
The label on the IC has the Texas Instruments logo.
On the first line, printed on the IC, is “J214A2” and the second line has “MR016”.
As best I can determine, these are custom markings for Sega/Gremlin.
When I searched on the internet for Texas Instruments J214A2 or MR016, I didn’t find anything useful.
When I looked at the manual (PDF page 125, manual page 121), in the schematics section, it refers to this IC as an 28L22.
My EPROM programmers (EETools Top Max and Data I/O 29B) did not have this as a selectable item.
However, at Mike’s Arcade, 28L22 is listed with a speed of 100ns.
It crosses to a Signetics 82S135 and a few others.
My programmers do have the 82S135 selection, so I can read it and verify it that way.
If you need a replacement, there were a few listed and some with a much faster speed of 45ns, so any of those would be workable replacements (if you can find one).
The other PROM is at board location marked U72 and is a 16-pin device.
The label on the IC has the Texas Instruments logo.
On the first line, printed on the IC is “J214X2” and on second line has “MR017”.
Again, as best I can determine, these are custom markings for Sega/Gremlin.
When I searched on the internet for Texas Instruments J214X2 or MR017, I didn’t find anything useful.
When I looked at the manual (PDF page 126, manual page 122), in the schematics section, it does not give further reference to this IC besides “”U72” and “MR017”.
However, one of the super sleuths on the Dumping Union (Caius) identified that this IC has the same pinout as a Signetics 82S129 (and several other crosses).
My programmer can select that, so while I haven’t tried it yet, I should at least be able to read & verify it that way.
If you need a replacement, as with the other PROM, I’m guessing that either the slower speed (50ns) or faster speed (25ns) crosses will work, again, if you can find one at all.

Sega PROMs from Zaxxon (Thanks to Joe Magiera)

One PROM is at board location marked U98 and is a 20-pin device.
The label on the IC has the Texas Instruments logo.
On the first line, printed on the IC, is “J214A2” and the second line has “MR016”.
As best I can determine, these are custom markings for Sega/Gremlin.
When I searched on the internet for Texas Instruments J214A2 or MR016, I didn’t find anything useful.
When I looked at the manual (PDF page 125, manual page 121), in the schematics section, it refers to this IC as an 28L22.
My EPROM programmers (EETools Top Max and Data I/O 29B) did not have this as a selectable item.
However, at Mike’s Arcade, 28L22 is listed with a speed of 100ns.
It crosses to a Signetics 82S135 and a few others.
My programmers do have the 82S135 selection, so I can read it and verify it that way.
If you need a replacement, there were a few listed and some with a much faster speed of 45ns, so any of those would be workable replacements (if you can find one).

The other PROM is at board location marked U72 and is a 16-pin device.
The label on the IC has the Texas Instruments logo.
On the first line, printed on the IC is “J214X2” and on second line has “MR017”.
Again, as best I can determine, these are custom markings for Sega/Gremlin.
When I searched on the internet for Texas Instruments J214X2 or MR017, I didn’t find anything useful.
When I looked at the manual (PDF page 126, manual page 122), in the schematics section, it does not give further reference to this IC besides “”U72” and “MR017”.
However, one of the super sleuths on the Dumping Union (Caius) identified that this IC has the same pinout as a Signetics 82S129 (and several other crosses).
My programmer can select that, so while I haven’t tried it yet, I should at least be able to read & verify it that way.
If you need a replacement, as with the other PROM, I’m guessing that either the slower speed (50ns) or faster speed (25ns) crosses will work, again, if you can find one at all.
