I’m also still very interested in this. Especially the PC-Speaker MixIn feature that other cards don’t offer.

Re: Anyone ever see one of these Gateway 2000 CrystalScan 1024s with both DB9 and DB25 inputs?
Posted on 2023-05-13, 10:52
I have the same monitor (mine is not relabelled as Gateway but branded MAG Technology) and question about the DB25 port function. I suspect it is an analog video input as I found evidence that this model could be a multisync monitor, not just an EGA one. I'm trying to figure out the pinout... …

Just noticed that there is a topic about the same monitor (relabelled as a Gateway 2000 CrystalScan 1024 ): https://www.vogons.org/viewtopic.php?f=63&t=62750 The same question about the purpose of the DB25 is asked but without any answer yet :( I have poked in the DB25 connector with a multimeter in …
MAG PMV14AC EGA CRT monitor: is it multisync VGA capable?
Posted on 2023-05-12, 17:20
I just received that monitor that was sold on eBay as a color EGA monitor. s-l1600 (1).jpg s-l1600 (2).jpg I’ve tested with a TTL EGA source on the DB9 port and it works as intended. I was wondering if it could also work with analog VGA. Maybe through the DB25 port? I scoured the web for the pinout …
Re: Victor V286P - clone of what?
Posted on 2022-11-16, 11:28
My VGA V286P finally arrived. It has the same VER2.06P BIOS as yours. Regarding the HDD replacement, I haven't opened the machine yet but it says here it's 3.5 inches RLL ST-506 drive: pretty difficult to find, especially in working condition. So I guess the best solution is indeed XT-IDE based, or …

Hello, I have the CGA version and just bought the VGA version on eBay (shipping ongoing). The CGA version powers on but usually doesn't display anything on screen (both on the plasma internal monitor and on an external one). On very rare occasion I made it display the setup screen (see photo) but …

Thank you!
Re: Video + multi I/O VLB card jumpers configuration
Posted on 2022-08-13, 09:56
Thanks! Also I just found something quite similar (same brand, same GP-4032 reference) but with different jumper blocks locations, except for the JP1 to 6 one which indeed seems to used to enable/disable all the features except for the IDE (looks like there are no jumper for the floppy). https:// …
Video + multi I/O VLB card jumpers configuration
Posted on 2022-08-13, 09:24
Hello, I just acquired the following BCM Advanced Research Inc. Rev 1.1 VLB ISA card with onboard video, floppy, IDE, joystick, serial and parallel features. However I couldn't find any documentation about it regarding the configuration of the 14 (!) present jumpers. IMG_5184.jpg IMG_5185.jpg The …
Re: Toshiba T5200 mods and upgrades
Posted on 2021-03-26, 13:37
Nope, the back board was fine. I've transferred and tested it OK on the plasma panel of one of my other T3200 (which board actually had issue since the display showed vertical lines, but there wasn't apparent leakage on this one either). The panel of the T3200 shown in the photo was just smashed …
Re: Toshiba T5200 mods and upgrades
Posted on 2021-02-09, 21:26
Have you, by any chance, modded / changed / dabbled in Toshiba T3200 as well? If so, how close are the insides to T3200SX? Enough to reuse, say, power supply or memory banks? I'm the owner of three T3200 (plain, not SX), one with a smashed plasma display. Rather than trying to find a replacement …
Re: MDA/CGA/EGA/VGA to HDMI using Raspberry Pi Zero
Posted on 2021-01-25, 14:45
The item can now be bought on eBay (only one left when I write this, but the seller seems to keep adding new batches). I did some basic tests with mine and I'm really impressed with the overall result. My main purpose is to get the best possible result on a LCD for old games without any deformation …

Hello Ian, Would that be possible to order a couple of these without going through stardot.org.uk? I'm personalty not (yet) into Acorn, having started recently in vintage computers and still sticking to the PC area for now. So it'll be inappropriate to subscribe to that other forum just to order …

Hello there, Sorry for necroposting but since I found this thread, I've been looking for an Acer Magic S23 and I recently found a couple. However I'm blocked with a really annoying issue. Upon testing, everything seems OK except for one thing: whenever I do a warm-reboot (ctrl-alt-del or restart in …

That is very generous of you! I'll be more than happy to pay you the shipping fees to my place (Paris, France). Also, I have one more question that I'd like to share on the public thread before I order the 256K x 1 bit chips: Is the 74LS158 chip in socket U84 required as for the 640KB modification …

Hello Greg, Does your shipping offer for a GAL still stand? I would be very interested to fill my IBM 5155 motherboard with 1 MB of RAM for having access to UMB. That would also allow me to save ISA slots (1/4 of them are currently occupied by RAM expansions to get to 640 KB). Thanks in advance!
