All my recent posts have been dealing with getting an FM Towns II computer in a suitable state to play Wing Commander. In the last of these I took a quick look at the analog controller I’ll be using and prior to that managed to upgrade the RAM from 2 to 10Mb. This time I’m dealing with the matter of getting a hard disk drive up and running.

Near enough all FM Towns computers include a SCSI interface for connecting up external SCSI drives and mine is no different having a SCSI-1 50 pin centronics connector on the back for this purpose. SCSI connectors have come in many shapes and sizes over the years but there are cables to convert between these and in theory it’s all backwards compatible. As such, my first thought was to find the cheapest SCSI hard drive I could with an appropriate cable to connect it up and go from there. With that in mind I bought this:-

This is a 2Gb IBM drive pulled from a laptop. It’s a SCSI-3 device with a 68 pin half pitch connection on the back. I found plenty of manuals on the web and tried various jumper settings on the hard drive (of which it has many) but was unable to get anywhere at all with it. Initially I was trying to set the drive up using a Towns 2.1 OS boot disk that came with the machine but found another guide on hard disk installation at http://illusioncity.net/guidefm-towns-how-to-create-and-format-an-hd-image-and-install-dos-with-cd-support/ .

The snag with this guide is that I needed to create a DOS boot disk and the Towns doesn’t even use a standard 1.44Mb format. I’ve managed to source a complete download of near enough everything released for the FM Towns (not one I can share unfortunately) which included the DOS disk images. To write a disk I had to connect up a 3.5 inch floppy drive to my modern PC and used a program called Omniflop. 1.44Mb floppies appear to work fine for this purpose. Omniflop is an old program but works perfectly in Windows 10 at least at the time of writing. It’s a simple enough process – just follow the instructions at http://fullmotionvideo.free.fr/phpBB3/viewtopic.php?f=5&t=1187.

The working boot disk didn’t actually help out as I still couldn’t detect the hard disk from the setup program. I clearly needed another plan so searched the web and came across the SCSI2SD device. This is one of those fantastic modern gadgets that makes retro computing so much less grief than it would have been a few years back. It emulates up to 4 SCSI devices at once including hard drives, CD-ROM and floppies, storing all the data on a swappable micro sd card. I ordered mine from Amigakit where it’s currently listed as SCSI to Micro SD Interface Adapter. I was slightly wary about this as there is a long list of supported devices on the Wiki which doesn’t include the FM Towns but it seemed the best shot.

I also ordered a case for the device from Ebay. These are 3D printed and include the cabling on the inside to connect to the board. This one has a 50 pin half pitch connector on the back. I can’t honestly say I’m too impressed with the quality of the case but it does the job. Just don’t expect to be able to get the SD card out without tweezers. You don’t want to take this thing apart too much either as the screws had barely any purchase on the first assembly.

Setting up the SCSI2SD is a matter of sticking in an SD card, connecting it to your PC with a USB cable, running the utility software and selecting a drive size. I set up a 1Gb drive but found out afterwards that Towns DOS won’t take partitions over 127Mb. You can set up multiple partitions on one large drive if you wish and there are different file table formats that you may be able to use if you know what you are doing. I stuck with MS-DOS since I know it will work.

There is no fdisk to partition hard drives on the towns and the system has a more all-encompassing setup program instead. The illusioncity guide linked above details what you need to do, although you can do the same job in Towns OS 2.1 by the looks of it. I’m glad to say that the Towns detected the SCSI2SD without any problems whatsoever and I was soon up and running. The power is drawn directly from the SCSI connection so there is no need for any power source other than the Towns itself.

That just leaves the matter of actually installing Wing Commander. I would like to think there would have been an installation program but the extra instruction sheet bundled in with the game says to manually copy all the files to your hard disk from the CD. This proved more tricky than it sounds since I’m dealing with an unfamiliar operating system in a foreign language. My first thought was to use DOS since the commands are the same. This appeared to be going OK until I noticed how just many different subdirectories I was going to have to copy one by one (there is no xcopy command on my DOS disk).

I swapped to Towns OS at this point. The file browser on this defaults to just showing some icons to run programs rather than the actual file structure. After randomly trying options, I realised that you can swap to showing the files by clicking the double folder icon at the top right of the window and selecting the second option down. After this point it’s a case of drag and drop. Wing Commander can then be started by running wc.exp and apparently defaults to English which is just as well.

It’s been a longer journey than I anticipated getting to this point but I’m there at last. I highly recommend Google Translate for anyone messing around with one of these machines that doesn’t have much Japanese. My phone struggles at times to pick up the screen clearly but it’s meant I’ve been able to decipher the menus in Towns OS and work out all the basics.

I do still have to set up the hard disk every time I start the machine since I need to replace the BIOS battery. This would be no small task in one of these things and would mean complete disassembly of the machine and probably soldering the new battery in place. I’ll leave that job for another time (if ever). For now, it’s about time I played some Wing Commander.

My quest to get an FM Towns set up continues. I’ve certainly learnt a bit but still had no success with my first attempts with an external hard drive so am going to try a SCSI2SD device next. More on that when it arrives and if I actually get it working.

In the meanwhile, I have received one more relevant bit of kit which I’ll take a quick look at here:-

This is a Sharp Cyberstick controller and is about the only option for an analog joystick on the FM Towns as far as I’m aware. There are some more conventional analog gamepad controllers but it has to be a joystick for Wing Commander.  The Cyberstick is also supported on the X68000 (should I ever happen to get one) and apparently on a handful of Mega Drive / Mega CD titles. Those Mega Drive titles don’t include Wing Commander I’m sorry to say.

It’s a fairly high end device with a good deal of customization options available. The most striking of these is the ability to remove the stick and throttle and swap their positions around. A little side benefit of this is that all the working parts of the analog controller can be easily exposed and serviced should it be required.

The unit is quite large but not as large as I might expect. Comparing it here to the Sony dual analog controller, there is a marked contrast in size and I would prefer the joystick especially to have been considerably bigger. I suppose this was aimed squarely at the Japanese market who presumably have slightly smaller hands on average. As for myself, I’m left holding on with my fingertips. The resistance on the stick is extremely low so it’s still very controllable like this.

The throttle on the left isn’t a true throttle as it returns to the center position when released. When using it in Wing Commander, it essentially acts as a switch to raise and lower speed. A true throttle would have been far more satisfying but limited the controller in other games no doubt. A switch to turn the centering off/on could have cured this but no such luck.

I’ve not played a lot of Wing Commander with the Cyberstick as of yet as I’m waiting until I get a hard drive. My main complaint would be that the controls don’t appear to be re-definable and while there are nice touches like being able to use the little toggle switch on the throttle to lock/cycle targets, the D button on the throttle only duplicates the B button on the joystick to fire missiles. This means that to use the afterburner, I have to let go of the throttle entirely to reach over for the C button in the middle. It works but surely didn’t need to be this clunky.

Truth be told, I’m a little disappointed with this controller. It’s like Sharp set out to make a flight controller and then thought it had better work with other types of games and compromised. The main body of the unit is large and heavy yet the two sticks themselves where you will have your hands 99% of the time are lightweight and a bit cheap. It comes across as a bit of a toy when compared to the Thrustmaster’s and the like that were on the PC’s of that era. As such, I’d rate this behind the Sony dual analog and especially the 3DO CH flightstick when it comes to the options for playing Wing Commander games on consoles. Neither of those systems had the original Wing Commander 1 & 2 though and this is definitely preferable to using a gamepad and/or keyboard. It’s an essential extra if you want to play Wing Commander on a real FM Towns but you’d better be more than a little fanatical about such things to make it worthwhile, or have really, really small hands.

I’m still trying to get my FM Towns in a state to play Wing Commander. It might help if I hadn’t spent so much time playing Truxton 2 on it but I have made some progress this weekend. The main problem I’m having is the lack of information and what there is often conflicting. As such, I thought I’d share what knowledge I do gain starting today with the memory upgrade.

My FM Towns II (like most of the models) comes with 2Mb of RAM. This was quite a lot for the time but that single speed CD-ROM drive just isn’t up to loading data on the fly (as shown in the fairly painful first attempt with Wing Commander a couple of weeks back). I gather some machines support EDO RAM, provided you set the appropriate jumper on the motherboard but I opted for what I hoped was the safe option of buying some 8Mb 70ns FPM, Non-Parity SIMMS from Ebay. Early FM Towns machines are limited to 8Mb SIMM’s as a maximum. I expect that’s not the case with my FM Towns II but 10Mb sounds like plenty for the games I have in mind.

The SIMM’s themselves are cheaply available, more so if you happen to be in the USA. I understand that other FM Towns models vary with many having several slots for SIMM’s but my particular UR model just has the one slot, conveniently located at the side of the case under a plastic flap:-

You can just see the Intex 486SX chip nestling behind the RAM slot. It seems pretty strange these days for a PC CPU to have no heatsink whatsoever but it clearly gets by without. I slotted my RAM in here and of course when I switched the PC on, it wasn’t detected. After much Googling I stumbled on a post at http://nfggames.com/forum2/index.php?topic=6150.0

The upshot is that pins 67-70 on the SIMM chip are used to report the size and speed of the SIMM in question. The IBM compatible chips use a completely different standard to those on the FM Towns so a bit of finagling is required. Fortunately, this is fairly easy to achieve with a soldering iron even for me.

The table above (stolen from the forum post) shows the settings required with O being the pins that should be connected. Most (but not all) SIMM’s will have somewhere on them pairs of solder points for this purpose.

The jumpers in question are at the top right of the chip I’ve used here. R1-R4 represent pins 67-70 in order. R3 was already bridged with a little connector. From the chart above, I also needed to connect R2 and R4. I just filled the gaps with a bit of solder and I’m pleased to report that my FM towns now detected the memory correctly on boot.

I should mention that the first chip I tried still refused to work as it didn’t pass the memory tests at startup. It may well just have been a faulty chip but I’ve heard that some SIMM’s can prove to be incompatible. The one that did work is an HP D2975A which is available on Ebay for under $3.

As far as improving Wing Commander goes, the difference is marked. During cutscenes, the extra memory appears to largely used as a cache, so the first time a given character or scene is shown it is still slow to load but once you have played a mission or two the CD isn’t even accessed most of the time. Gameplay itself is all pre-loaded before the mission and the game is so much more playable now, albeit with a really, really long loading time for that first mission. It’s still quicker than playing Wing Commander 3 on a 486 was.

I’m going to be needing that hard disk if I’m ever going to play Wing Commander 2 as it requires installation to run at all.  I have the hard disk but am still waiting on the SCSI cable to try it out. One hitch I know is coming is that the BIOS battery on this thing is long dead and it appears I will have to completely dismantle the machine to get to it. The hard disk will need setting up every time I switch the machine on if I don’t fix this but I might just live with it depending on how much grief it causes. I definitely want to get the hard disk up and running first..

The main thing that is keeping me from a Wing Commander playthrough is that I really don’t much fancy using the keyboard to play the game. The solution to that problem is being delivered next week so providing it works I hope to have this fully up and running before too much longer.
