Hi all,
I recently acquired an Dev.Box HKT-01 that was in bad shape. The GD-ROM drive latch was broken so the drive would not stay in. I fixed that with some super glue and 3d printed rings to hold the latch together. In addition, after some troubleshooting, I had to replace the ATX power supply. Luckily I had one that did -5 volts. The cables were barely long enough and I had to route the PS cables from the left side instead of right but it sorta works.
At the moment I get nothing but a black screen. I tried VGA and composite. Tried the internal test and still nothing on screen. The caps on the board all look good and the solder joints are shiny so I think they are okay. I've done lots of capacitor rework (I restore vintage computers) so have seen much worse caps but I will consider recapping if needed. When the power supply was weak, the SCSI hard drive had issues. The power supply failed completely after maybe 10 power cycles so I knew that was toast. I believe that replacing the power supply got the drive going (although it's a bit noisy as it spins up and down which I don't like hearing). So I need to archive the drive.
Question 1: Should I see the internal test if the box is working at all?
Question 2: I am guessing I need to replace the battery or can I remove it completely? That's a rechargeable one, correct?
I have ordered an Adaptec AHA-2940 and the HD50 cable (too new for what I usually work on). I have a PC with an Adaptec AHA-1542 card so I would like to back up the drive (if it's working) before I do anything.
Question 3: Is the drive straight FAT32 so I can attempt to connect it to a Windows 95 box (my diskette archiving box) an just copy it to a USB stick or use WinImage or something?
Anyway, I will update progress here. It is a SET5, specifically 5.24 according to the serial number? I've read off the EPROM marked "SET5 7676 VO.71 98-11-13" and it's on an ST27C160. My checksum is off, however. I assume the checksum is supposed to be "7676" but it's actually "7671" when read. I am thinking that may be a possible problem too?
I don't know where to find the board model numbers but if I need to find those, I will. For now, if someone can assist with the questions, I prefer not to try anything if there is something on the hard drive. This one is in Canada.
Thanks for any help.
