Check ps-2.kev009.com/ohlandl/SCSI/MCS.html The board looks very similar to the MCS-600 probably a OEM version for Quantum to support their tape drives. I would give the drivers a try.

Feel free to contact me, I just did not check my mails for weeks. I will be lucky to share my collection with you. Just did a swap on cfgs with another user on a german classic computer forum. I would contact via PM, but I think I need a post count of +50. Are you on vcfed,org? Was that 1st1? he's …
Re: Compaq Deskpro M and XL models.
Posted on 2020-05-19, 06:03
The Prosignia 300/500 has a different planar, but the CPU complex is identical with the XL. I swapped them so often, I still dont know what board originated where. The only difference might be the bracket, but I am not even sure about this. I do not remeber plugging a fan to the CPU board, only to …

The PS/2 floppies are also knows for dried out electrolytic caps. There are manuals online how to use a standard 34 pin floppy on the 26 pin PS/2 header. For the MCA sound boards, there is an ongoing project for Adlib clones. Even for PS/2 enthusiasts the MCA sound boards are rare and allways …

Other options are local car boot or garage sales. even if there is often nothing to find, prices are often very cheap. Especially if the seller doesn´t know what they sell, and you make an offer for the whole box. I remember finding some real nice pieces and leaving even more behind on some flea …

Quick add on: Deskpro 486/33L has CPU board while 486/50L has CPU on planar. Some L and Systempro CPU board are single use only and cannot be used for Systempro dual CPU, while 386/486 combo is supported. I probably can provide info on the Systempro and Deskpro N due to complete system reference …

Hi there, Eisapc, are you knowledgeable with electronics and using multi-meter? I'm interested in power supply pinout for Deskpro M. Sure I can, it may just take a few days. Machine and multimeter are at hand, I just will be off for the weekend. Fot tweaking the XL Socket 5 Pentium boards I was …

Did you try to unplug the HDD to see if it boots from FDD? One reason might be a defective FDD drive. I can not remember if there are switches on the motherboard to overwrite boot priority in the BIOS setup. The adaptec does not need dos drivers for the disk, but for the CD if it is SCSI.
Re: Compaq Deskpro M and XL models.

Having multiple Deskpro /Ms and /XLs I can confirm these are perfect DOS machines. Both can be easily upgraded by swaping the CPU board to P66 for the M or PPro for the XL . The P90 board of the XL can be tweaked to P120, but never found a way to make it run @133 MHz. Some Prosignia used the same …

The @FFE0.ADF and option disks containing adf and drivers are linked on the mentioned site. Problem might indeed be located in the 32 bit interface of the card and the 16 bit PC. The 486slc2 is a kind of overclocked 386sx, no real 486 at all. There are no references for the board to be compatible …

Isn´t the BIOS support limited to 2 disks only? Running more than two disks will require the driver.

So have you tested TIGA under Windows? My understanding is that it shouldn't be worse than 8514/A, which was it's main competitor. Apparently Hercules' main target market for their TIGA cards were Windows users. I've never owned a TIGA card, so I wonder if there is much variation in performance …
Re: Performace RAM: EDO 168 vs EDO 72

These IBM use buffered 5V EDO DIMMs. The only other machines using these I know are the Vectra XU6/200 Dual PPro and some IBM RS/6000. Due to the buffer it might be slightly slower then conventional EDO RAM, as mpe allready mentioned. if I remember right both types of slots can be populated to max …

I own some Disc Coprocessor Boards (DCB) made by Novell and others. These are as well simple SCSI or SASI Controllers used to attach drives to Netware servers. Boards do not even have a BIOS nor any kind of CPU, only logic chips. Other gues could be QIC-02 or QIC-36 Interface used for tape drives.

Not sure about the SMART 2/E, but I can confirm the SMART working in the Prosignia and due to the fact it based on the same technology it is most probably supported. Missing W9x drivers for these controllers are definitely an issue. Did not think about tis due to the fact mine are running Netware …
