Plus / minus 1 V doesn't matter.. as long as amperage is the ~same or larger. As to plug, it can be changed, some power adapters come with number of exchangeable plugs. Also, you have to have old battery pack in the computer. If you don't have it, it's OK - just make sure you connect 10k resistor in …

I have 3 of those machines (transmissive, transreflective and colour) for quite some time, and only one working pen (and they are VERY hard to find nowadays) I know that there are compatible pens that work with st1000 (I tried the friends pen a long time ago, I think it was HP tablet? don't remember …

It came with NiCad 6-cells battery (so, 7.2V) . I think you can try to replace it with 2 Li-Ion cells (7.2V). I am thinking about this because mine seems like dying. https://www.instructables.com/Weekly-Project: … nd-a-Project-G/

Any news? If someone send me modified BIOS, I may find a courage to attempt to remove EEPROM and reprogram it.

I have the same machine (PC-4600, with HD).. I used it for some (slow) EPROM programmers that do not work on faster machines.. Because of some screeching noises from HD (when head is moving) , I would like to replace it with CF card.. (I did that for my Stylistic st1000, now it is faster than ever …

Very interesting :-) I have T1850 with HDD problem (FDD as well, but this can be sorted by replacing belt). De-soldering the original eeprom is not a problem, but editing BIOS is.. In case somebody did this and their machine worked, I would greatly appreciate the modified file :-) Thank you in …

Let's see if you can download the bios from here, if someone knows how to upload it directly to the forum, do it. https://drive.google.com/file/d/17oBbn39YTnjyFex0tOs6h80JizBZN8wJ/view?usp=sharing If you have progress or want to try the modified bios send it back to me: z7upower@yahoo.es I also …
