So it turns out that IDE over ISA didn't work, but experiments with a normal non-proprietary FDD have actually been successful! :) I took out the proprietary floppy drive, put in the ISA I/O controller card and attached a normal floppy drive from Mitsumi on the controller's FDD connector. For now I …

Put the Adaptec and quantum in the Toshiba ..but it fails to boot ..hanging (cursor flashing) after memory check. Perhaps I need to disable the Connor in bios rather than just pulling the ide connector ? How do I enter bios on the Toshiba ? Can anyone advise ? I have had the same experience in …

The retr0bright process can weaken the plastics so there are two camps of thought and it usually is divided between collectors who like the better looks and then the preservationists who want to keep the articles in as original condition as possible. I am not a collector. I don't hoard the objects …

The controller card has arrived. I will try out later whether this will help in circumventing the BIOS limitation in regards to booting from HDD and FDD. I will put in the original unmodified BIOS chip that only lets you boot from Conner hard disks beforehand to make sure this also works with an …

thats a nice keyboard! Yeah. A super groovy guy on the western frontier found that unobtainium keyboard in his stash of hardware and sent it my way. I got real lucky! A tad yellowed, but it toally fits the system model-wise and the stain can be tackled at a later point in time anyways. Neat system …

Got a Data Technology Corp. DTC2280 Super Controller Card. 2x Serial, 1x Parallel, 2xIDE, 2xFDD + Game Port. this will come in handy for sure. 9DQ1nCL - Imgur.jpg Interestingly the manual talks about "Jumper 11" that is supposed to switch the Parallel bi-directional mode, but it is missing on my …

Yeah, because it could very well be that, although the non-proprietary FDD and non-Conner HDD I aim to try will be successfully detected and are usable over the controller card, the Toshiba still would deny to boot from them. I will put in the old unaltered BIOS for this test to make sure this will …

There are 8bit and 16bit ISA controller cards, if I remember correctly. I ordered one of the cheapest 16bit ones of ebay that I could find. As with regards to adding sound later: I also thought about possibly adding a Soundblaster card. But as you said it would have to be 8bit then as the controller …

Other models of the Toshiba T-series that seem to be affected by this limitation turn out to be the T2000 as well as the T5200. Refer to this thread for more information regarding the T5200 --> A couple of retros I'm working on.

I am hoping to solve 2 problems at once here..: IF it is possible to use/boot from a standard non-proprietary floppy drive AND another non-Conner HDD with the help of an ISA I/O controller card (expansion ISA cards that bring with them extra serial/parallel and most importantly IDE and FLOPPY …

The service manual will help you greatly when it comes to disassembly of these machines, a lot of things aren't that obvious. You have to dismantle the whole display and guide the cables back through the cable binder in order to be able to get the top of to reach the back part of the planar. I will …

If the BIOS limitation is present, then everything besides a Connor will result in the Toshiba aborting the boot completely, no chance. I wonder if the BIOS alteration like done by HighTreason for the T3200SX would be possible for this model as well. I would definitely try out either I/O card …

I'd also prefer an ISA card. LPT port getting pretty crowded by now. You have to keep in mind that these range of products seem mainly aimed at ppl with either a modern PC that still have a parallel port but ofc no ISA so they can enjoy old games with correct sound, or ppl with older laptops that …

I was wondering whether an ISA I/O card with an IDE header would also be a suitable solution to the "only booting from Conner drives"-limitation. I wonder whether this limitation only applies to the IDE header on the mainboard. Another model series also suffering from these limitations seems to be …
