Yannil Posted September 30, 2023 Share Posted September 30, 2023 I bought this 1050 drive off eBay a while ago and I have just got it working again. I was wondering if anyone recognised the upgrade board. I thought it might have been an IS Plate purely down to the colour of the PCB. But it is not recognised as such by the ISP software. Happy software recognises it as being Happy but might it be something else? Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted September 30, 2023 Share Posted September 30, 2023 Won't be an original happy. Probably a clone. Lazer perhaps? Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted September 30, 2023 Share Posted September 30, 2023 the builder went to extra effort to anonymise the ICs so, do we think theres a windowed EPROM under that warning? Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted September 30, 2023 Share Posted September 30, 2023 If its a "lazer" it would function as a rev 1 happy 1050 (no corrupted single density ultraspeed writes, unbuffered) and not exhibit those symptoms like the more common rev 2. Its been a while to remember but if you start the genuine happy 7.x diagnostics software, see if the ROM test results in "Pass" or "PASS" - as that differentiates V1 or V2. (Or "FAIL" if the rom has been modified and checksum matches neither). Lazer had a modified utility disk to pass on its own modified rom...

+Larry Posted September 30, 2023 Share Posted September 30, 2023 Will Happy 7.1 software run properly on a Lazer? Is a Lazer different hardware-wise than a Happy? Just curious -- I've never seen a Lazer. Quote Link to comment Share on other sites More sharing options...

It has what appears to be a header for the Happy Controller option, so likely a Happy clone. Quote Link to comment Share on other sites More sharing options...
+nasty niff Posted September 30, 2023 Share Posted September 30, 2023 Looks like this drive strange https://www.ebay.co.uk/itm/325832013551?hash=item4bdd19f6ef:g:FTcAAOSwxTNlGEL9&amdata=enc%3AAQAIAAAAwOByKaxg8QNdTGGR0AAZrHXkDqcX2KjqOlqEoU7UuXXs3NXNjaeExwcZgLBHzJsLbZDZYLA8OJqpl7NsiDWjKLTrOkAtp2Z9GO%2FxOibPCXUMI9Y5ckKu05E82btYILA8LIOCVeb9a5OYv7OSlIcYwwkED%2FVY%2BLGkc4sPtCpl4pUubtzhuHV9HzUcjPW1LYi3vkJRqQNCLS2f7SQ%2FNKR7jcOLFikV9LPx4eOi8Cx7iVCYIV4ion22rUHmMKfxGddwGg%3D%3D|tkp%3ABk9SR9j22PncYg Quote Link to comment Share on other sites More sharing options...
Zolaerla Posted September 30, 2023 Share Posted September 30, 2023 I've written a software detector that can determine all sorts of drives apart. For Happy 1050s, it can tell the Rev 1, Rev 2, Tygrys, and I.S. Plate apart and will just say "Happy Clone" if it can't tell if it's any of those. I've been debating making a separate utility just to do the detection and give a report, but right now, it's just a part of a custom OS booter I've been working on, but maybe it can help? 2 Quote Link to comment Share on other sites More sharing options...
phaeron Posted September 30, 2023 Share Posted September 30, 2023 Definitely looks like a Happy 1050 clone, as the chip and controller connections match, including the connection to 6502 pin 38 (SO) with the 10K resistor to ground. Which if true, would make the chip on the right the 6502, the one on the lower left a 74LS139, and the larger 28-pin chip above it the 8K ROM -- and probably RAM and bank switching logic underneath the cheesy cardboard protector box. 2 Quote Link to comment Share on other sites More sharing options...
