I have found the model on a sticker in the back, it's a 1335 Micropolis drive: http://www.mfarris.com/hard/specs_micropolis/ … polis_1335.html Still it does not boot 🙁
Micropolis ST-506 MFM HDD: geometry values?
Posted on 2017-05-15, 10:50
Hiya! I just received an old Olivetti 286 PC that came with a Micropolis ST506 MFM HDD on a WD1006V-SR2 controller : http://i.imgur.com/nppCX85l.jpg the DALLAS RTC has died (ofcourse...) so the geometry info in BIOS is lost. But I am unsure what to enter as MFM drives are not my specialty :lol: I …
Re: Roland ACB Adapter With High 1200mA For SC55 Help
Posted on 2017-05-14, 19:12
Ofcourse I wasn't suggesting one should use a 24v PSU 🤣 , just what the 7805 could take as max. I did not think of the rest of the components being rated lower than 16v TBH, my train of thought stopped on the 7805 heatsink that won't like the extra heat once you go pass the 10+ v mark ... 🤣
Headland HT12/A 286 chipset: UMB driver?
Posted on 2017-05-14, 16:28
Hiya! I have a couple 16mhz 286 motherboards with the Headland HT12/A chipset and I was wondering if there is a UMB driver for it. I have tried "The Last Byte Manager" that provides up to 64kb of UMBs for the HT12 chipset but all it does is hard-lock both machines... :depressed: Perhaps there is a …
Re: Roland ACB Adapter With High 1200mA For SC55 Help

The SC-55 really uses a 7805 to power it's electronics so it can take more than 9v - max is 24v or something IIRC. The only issue is the heat and the included heatsink is designed to work around 9v ratings. The higher voltage reading with no load is perfectly normal on unregulated PSUs.

1200mA will work just fine, the SC-55 will only draw what it needs and the PSU will provide that. It's the other way around that won't work: 500mA PSU and 1200mA device. Getting a higher voltage reading on these old unregulated PSUs without load is perfectly fine, if you measure it connected to the …

Diggers by Millennium Interactive happens to be one of my favourite DOS games ever.

Re: EGA cards: are there significant differences between models? Recommendations?
Posted on 2017-05-11, 18:19
I have only tested CGA and VGA on my XT build they seemed OK. I would guess that since EGA/VGA games are more demanding on the system a 8088/V20 is not enough. Unless you are referring to EGA games being faster on a VGA card and slower on an EGA in the same XT? I will post pics of the monitor once I …

Thanks for all the suggestions and input, I'll look for a Paradise or EGA Wonder card then - it is also interesting the original IBM card is slow, nice to know. I will study dr.zeissler's link, really interesting. I have benchmarked several ISA VGAs on my 286/16 system with Wolfenstein3D - WD90C30 …

Hiya! The time has come to delve into EGA territory since I found a color EGA monitor :lol: (the plan is to use a 286/16 system already in my possession and replace it's vga card with an ega one) I never had an EGA card so I am unsure of the details, do they come in faster/slower variants like VGA …

Added bonus is that it also acts as a full USB soundcard when it's connected via USB ie it plays system sounds not just midi. I have tested it in a pc as low …

From my tests I concluded that all the Nvidia cards from riva128 and up to (at least) the GF4 cards all have the sane VGA core. I benchmarked several on my 233mmx , for example a riva128 and a GFMX440 have no difference in speed under DOS. What is nice about the nvidia cards is the VBE3.0 BIOS - so …
