Turns out the only significant problem the DKJr was dead EPROMs all the program EPROMs were partially erased, resulting in garbage opcodes being retrieved by the CPU. The UV eraser I bought on eBay turned out to be a death-trap, so I was very happy to have an alternative. It came with a GAL adapter, a crapton of extra GAL's, the library EPROMs, emulation leads, booklets, adapter and also a nice little UV eraser.
#DATAMAN EPROM PROGRAMMER SOFTWARE#
Pretty cool! The software to download ROM images from and to the PC is a little dated, but works perfectly. It allows you to read, program, test, copy, and simulate EPROM devices, allowing you to make changes to your program on-the-fly. It's an older device, appearing first around 1992. The Dataman S4 is a pretty neat, standalone, battery powered device that allows you to download or burn EPROM's without a PC. I didn't realise at the time that other devices would require the use of an adapter, but more about that later. On paper, the compatibility list was pretty long, as it seemed to have the capability to program nearly all EPROM types, including 16 bit variants. I found an older Dataman S4 programmer online, and picked it up on my way from work. Your milage may vary, and I'm sure there are all kinds of reliable programmers out there, but I wanted one now. It usually works barely, with poor compatibility on newer OS'ses or shady, blue-screeny drivers. I also have pretty bad experiences with the software that comes with these kinds of products. Time to buy an EPROM programmer/reader! I knew a Chinese programmer could be had relatively cheaply, but I wasn't looking forward to having to wait weeks for the thing to arrive. What worried me a little was the fact that the EPROM's sitting on the main CPU board all had their little window exposed, and for all I know that board might've been sitting in bright light for a long time. I traced most signals from the CPU, that seemed to be working nicely, but it only displayed some random garbage on the screen. The Puck-man PCB worked nicely after some touchups, but the Donkey Kong Jr board gave me headaches. Slightly too valuable to keep around collecting dust, so I sold it on eBay to a collector. The Popeye PCB turned out to be a converted Skyskipper PCB. Much to my delight, it contained a bootleg Puck-man PCB, a Donkey Kong Jr. Sometime ago, I bought a cardboard box with some old arcade PCB's of of the internet for next to nothing.
