Edit: I have found that the Jumper Link does not want to stay plugged into the RAMLink connector when plugging in the RAMLink into the cartridge port but I could not see that with the cover on. If I put a little tension on the wire from inside as I plug the RAMLink in it does not pull to the side and lose contact. I am going to try to attach the wire in the case with some electrical tape to keep this from happening. Those who suggested the Jumper Link were correct I think. I will update this later if anything changes... Earlier: 128 mode RAMLink issue update: a4000t suggested trying it without the SIMM installed and many of you suggested the jumper clip be installed. I had tried the jumper clip during the 2 days I was trying to solve this issue but, since it had no effect, I left it out of the video. I have gone ahead and reinstalled it since it can't hurt and then I turned to the simm. So far, after removing it (And all the external drives) it is running on my bench. I had run a RAM test on the SIMM with no issues found but now, with it removed, things are stable so far. Apparently the RAMLink reserves some memory since the 1760 now reports 1728 blocks free instead of the 1984 it reported with the SIMMM installed.

This may seem like an odd question, but, why use Jiffy DOS on a Commodore 128 computer and its 1571 Disk Drive? They both have a burst mode (fast made). So, what else is Jiffy DOS used for? 🤔
@RavenWolfRetroTech5 ай бұрын
Remember that in a list of questions, every other one is odd! Even if the speed is similar, I really love the abbreviated syntax for DOS commands in JiffyDOS. Besides that I have the HD-20 and RAMLink that support JiffyDOS and I don't think I would do well using different command syntaxes for some drives. Then there is the elephant in the room! We all know that most 128s spend the majority of their lives in 64 mode. Back in the day I used 128 mode for 80-column text editing (With Word Writer 128) and Assembly coding (With the LADS assembler). Even then the code I was writing would only run in 64 mode as would most of the software and games I owned,

The ZuluSCSi can default into a "Fallback" mode where it works more like a SCSI2SD instead of a Zulu or BlueSCSI (which is the .hdf files) - that's probably why yours works. If you took that SD card off a SCSI2SD V 6 it just sees it as a hard drive. I found this out accidentally myself, and confirmed it with Alex Perez. It's not really designed to work in that mode, but it does.

Interesting. I don't actually have another SCSI2SD Device. I am pretty sure what happened was that I accidently put my Amiga SD card onto it because I was later unable to find it when I needed it.

If I recall correctly - after some 25 years... If you have 16MB RAM installed and plug, say, a 1750XL 2MB REU into the pass-thru port (I think)... you'll have 16MB RAM in the RAMLink + 2MB RAM in the REU as expected. They do not combine into a continuous total of 18MB, though. GEOS sees them as separate entities. On the other hand - and again, if I recall correctly - plugging the REU into the front cartridge port causes the 2MB RAM in the REU to overlap addresses with 2MB of the RAMLink RAM, effectively giving you 14MB + 2MB of RAM, again, as separate entities. Somebody correct me if I'm wrong about this. I just remember getting different results like that with my 1750XL REU whenever I'd plug it into the different ports. Better to go with the 16MB + 2MB, IMO.

As a consumer this is correct. Improper cleaning could cause damage and there are high voltages in the drive that could cause injury to the unaware. I do use a cleaning diskette regularly, However, the proper way to clean a drive by a technician when servicing is with a swab and alcohol. In fact, in my floppy disk cleaning video there are some instances where the cleaning disk would not clean the heads and even a swab took several minutes to remove the severe contamination from bad disks.

Do you have an RR-Net cartridge (and a WiFi bridge / Ethernet to WiFi adapter to connect it to)?

As awesome as all that is, it'd render all my games unplayable, as all my games are on cassette. Over 100 tapes, most of them originals, though a massive number(not quite half, but might be close) are "covertapes", which were cassettes that were taped to the front of magazines, usually having a commercial game demo on one side and a freeware/PD game on the other. Would've loved a setup like that, but I couldn't even muster the cash for a 1541. Of course, I was 5 years old, what'd you expect?

If changing the JiffyDoS switch on the RAMLink to disabled did not reenable the cassette port then you could just unplug it. I too used a Datasette for a year before I could scrape up enough to buy a disk drive - and I was 19. It sounds like you have a nice collection!
@fattomandeibu6 ай бұрын
@@RavenWolfRetroTech I think the key thing to keep in mind with C64s and cassettes in England, is game consoles such as the Nintendo Entertainment System and Sega Master System didn't arrive until 1988, so until then if you wanted to play video games, it was either an Atari 2600 or a computer. Being parents(oftentimes low income, as anyone with more cash would've got an Atari ST or Amiga) looking for cheap toys for their kids, cheap computers like the C64, Sinclair Spectrum and Amstrad CPC started shifting in large numbers, but sans floppy drive to keep cost down. The advantage of cassette, was that the games were ridiculously cheap(and a lot more readily available in shops than disk games) and could go for as little as £1.99(approx. $3). They'd bring out new games in big boxes and sell them for £9.99(about $15), then after they sold, I think 250k copies, they'd put 'em out in regular jewel cases and move them to the £1.99 section. That, combined with how computer magazines would always have a tape stuck to the front cover, meant I could pretty much get at least a new game every week and ended up with a kinda accidental collection.

Those are some k1ll3r upgrades (had to 1337 myself there, as the AIs can go crazy on ya). I finally after many years managed to get a 1571 for our 128 but two issues: the 128 is not working atm and the 1571's power board managed to break during shipping. I think it's OK otherwise but yeah, I hope I can find a new board so I can solder that board together and make the 1571 work. My crown jewel so to speak is the 1570, now while not as cool as the 1571 (it's just a 1541 with burst), it's rare, so I treasure it. Always wanted a 1581 so might look for a modern solution to that. Anyway, huge tangent aside: your game looks really interesting. I think it runs on a stock 128 but takes advantage of various upgrades?

Bummer about the power board. One good thing is that, since the drive heads go bad now and then and cannot be repaired, you should be able to find any other part you need for a 1571 from collectors who often have an abundance of everything else. I'm amazed you have a 1570, its such an rare and interesting drive. My game runs in 64 mode. I started making it on my Commodore 64 in 1983 or 1984. I used a 128 later for text editing and compiling in 128 mode but the game still needs 64 mode.
