What a great find. Everyone here is going to have their own anecdotal personal opinions on this. Here are mine.
It has workbench 1.3.
Good to go!
No really, I'm serious.
It has 5 megs of ram.
In all reality, this is plenty for nearly everything on your list except 1 thing. (more on that later)
It came with a 3 ¼ and 5 ½ floppy.
Those 5.25 floppy drives are quite rare, and more a sign of the times. I've never had a need for one, but I have friends who will get them simply from a collection standpoint, or if there's an IBM PC bridgeboard installed (also rather rare) - which you have! It's an interesting thing.
It came with 2 1042 monitors.
It has 1 meg chip ram.
I'd upgrade to 2MB, but it's not really a huge requirement. More a nice to have and something I'd put low on the list of to-dos. It's not easy to get to under normal circumstances. You have to remove the entire hard drive caddy.
Hook it up to a modern LCD.
You can do this with a buffered video cable and an LCD monitor that supports Amiga modes. I have ... a couple. I prefer the RGB/CRT look most of the time, but LCDs are easier to replace (far cheaper, more plentiful) and use less power. But to each his or her own. I would recommend some LCD options but I can't remember if you said if you were in the USA or elsewhere.
Speed it up.
You won't need an accelerator to play Monkey Island. I have an A2000 with a GeForce 030 @40Mhz. It rocks. But if you want to play Monkey Island and other games like that, it won't offer that much to be completely honest. But I do love mine.
Use a modern mouse.
There are various adapters that allow for this. Depends on what flavor you want.
Get it on the internet.
For me, this is 100% the last
thing I'd ever want to do with my Amigas. I will BBS with them nearly every night using a WiFi modem via the serial port, but the last thing I want to do is stick them on the 'net. Even a maxed out A4000 filled to the gills is going to offer a very shitty experience imo for the price. It will be slow, it will strip out nearly all of the interface, and a lot of sites simply won't work at all. And this is where you might actually benefit from gobs of RAM, a whacked out accelerator and more chip RAM. And will it make it amazing? Nope. You could hit this site with it, for example, but now that https is a requirement only 1 browser that I know of will work. You'll have to pay for it (even in 2020). And it'll still suck. To get a TCP/IP stack you would want to likely swap out your KS ROMs to 3.1 at a bare minimum. But just know you'll be sacrificing potential software compatibility to gain that glorious internet experience on your Amiga 2000.
Update the GUI.
Do you mean with MagicWB or icon packs? Or moving it from 1.3 to ... whatever? I could offer you some custom 1.3 icons
to swap in. =)
Modern storage: ide, flash, usb stick etc.
From what I understand, you have 2 SCSI cards right now. Assuming those drives are dead yet the cards work, if it were me I would attach a (modern) SCSI2SD card
in there and use SD micro memory. You could easily add a few gigabytes of hard drive space and not have to barely lift a finger. The larger the drive, the longer your machine will take to boot, btw. A lot of people here will add 4GB drives, or beyond. My current A3000 machine I'm building I put a 512mb sd card in there. It boots in 7 seconds, and half a GB of space feels ENORMOUS on these machines, to be honest. And you can always add more drives if you really need to. That's the beauty of the A2k/A3k in that there's tons of space to hide crap. Your machine's noise would dramatically drop, as would its power needs.
FWIW, I replaced all of my fans to quieter ones, too. My A2ks and A3ks are not silent like a C64, but they are very quiet.
I use the SCSI2SD cards in my 1.3 and 3.1 machines. You can move to IDE if you want to, but you don't have
to unless you just really want to. SCSI is fast and stable and at your fingertips. If your Dataflyer has the RAM board option, all the better.
Lastly, if you want to use a USB stick with your A2000, you might consider removing the 5.25 drive and putting in a Gotek. But I'd keep your original 3.25 floppy drive, too, assuming it works. I totally understand the convenience of a USB stick to move files here and there. However, for the A2000 another very cool option is the Rapid Road with X-Surf. But that does require WB 2.0+ and RAM and a mild accelerator (not much). So, there's that thread on the sweater being pulled...
I hooked it up to the monitor and it will start with a 1.3 disk in the drive but I can’t get it to boot or recognize either hard drive.They had to be in the machine for a reason. Was there a trick to get it to boot from a hard drive?
This has the potential to be a rats nest. There are a lot of variables involved since you have two SCSI cards and 2 drives. Problem is, we've no idea which drive was the boot drive. Did you try to remove one drive, then boot? Then, try the other? When you turn the machine on, if no drives are detected at all that's when you'd put in your Workbench 1.3 disk. This can be a pain, but if you have HDinstTools on a floppy disk you can see if the machine detects the drives at all. You might have to go floppy first just to diagnose the situation. If neither drive is detected, well then that sucks. And that'll probably be the first major project you'll need to solve before doing anything else.
Technically you could play Monkey Island off floppies, but I doubt you'd want to do that with all that hardware on your desk.
That's my take!
