Today Hammy sent me 3 PAL chips.
We have one from the M84 Hammerin’ Harry, this one is very similar to the one we already have but it has a “-D” appended to the label ID. Next one is from the M72 Hammerin’ Harry and the PAL from Warriors of Fate on CPS1.
The Hammerin’ Harry ones have been tested by Hammy.
Thanks to Hammy for sending these.
Today I dumped the PAL from a Real Break – Billiard Academy PCB (a pool game manufactured by Nakanihon in 1998).Device was an unsecured PALCE16V8.
Today we have some new PAL dumps.
‘coolmod’, one of our finest contributors, sent in different dumps, all are untested since they come from not working PCBs.We had from him dumps from these boards:
Artemio Urbina sent in dumps (from seven devices) from a Thunder Zone PCB, according to him these are specific to the Japanese ROM set so they may not work on other versions
‘chaneman’ sent in dump of a 82S153 device found on a Pengo bootleg board.He also send info on how to run on this board an unencrypted version of original Sega game code, you will find notes on database.
The user ‘undamned’ from Arcade-Projects forums dumped the PAL marked ‘D77-20’ from the Taito F3 cartridge ‘Kirameki Star Road’, device was an unsecured PALCE16V8 @IC37:
Lastly, I converted to GAL16V8 a BPROM found on a Black Tiger/Black Dragon PCB.Dump of the BPROM (a Fujitsu MB7114 marked ‘BD03’ @11K) was taken from MAME ROM set.GAL conversion was successfully tested by the Arcade-Projects user “rewrite” on his board which was missing this chip.
Thanks to all contributors.
I now have a way of creating new DS2430 replacements for a Konami Viper Silent Scope Fortune Hunter game.
I can only do Silent Scope FH at the moment but I might expand to other titles in the future if I get hold of the hardware.
The DS2430 has a unique factory lasered registration number which is used as part of the security of these things. As long as there is a good Timekeeper NVRAM fitted then the game will reinitialise it on this game and it does not seem to play a part in the security.
If anyone needs a replacement then get in touch and we can sort something out. I will need the ROM ID from a new DS2430 in order to make a new file.
At first glance the Seibu ‘UEC-51’ (also found marked as ‘HB-5’ or ‘UEC-05’) looks very similar to its successor ‘UEC-52’ :
Both are RGB DAC in SIL package used on some Seibu/TAD Corporation PCBs.But, pin number apart (20 for the UEC-51, 22 for the UEC-52) they have different design.This reproduction project started while I was repairing a Toki PCB which had some video issue that I pinpointed in this custom (althouhg later I found the issue was due another fault).As said, the ‘UEC-51’ acts as digital-to-analog converter of the color palette data (12 bit in total so four for each color) but, compared to the other DACs (like the Taito ‘TC0070RGB’), data are not latched but buffered.Obviously also here three R2R (resitor ladder) circuits are used in final stage to perform the analog conversion.As always in my projects, for first I figured out parts and design adopted, in this case I didn’t remove all the coating but simply exposed pins of the two ICs:
Then I carried on my test on some protoyping breadboard:
Test was successful so I drawn schematics and route them to a PCB layout trying to keep same dimensions of original part.This is the final result of a populated PCB (note the use of CMOS logics on it)
Definitive testing of the repro was done on a Toki PCB:
For reference, it seems the ‘UEC-51’ can be found on these PCBs :
As ‘HB-5’ on :
As ‘HB-5’ on or ‘UEC-05’ :
See you all to my next reproduction project!
