- First: Are you able to use double-sided (800KB) disks with
- this computer?
- If you can format disks two-sided try the following...
-
- Obtain the 'NewLife 1' CPU upgrade from NewLife
- 1-800-663-6395 Ontario, Canada.
-
- This will give you Mac Plus equivalent if not a bit faster.
- There is also space for up to 8 SIMMS to a total of 4MB.
- The SCSI connector allows use of HARD DRIVE.
-
- Second:Get 8 256KB SIMMS. Since they should be FREE (no use to
- anyone anymore) get a dozen. You will have extras in case
- one is bad and you can swap/test combinations until they all
- work. (Static charges might kill a SIMM)
-
- For $300 (especially US$300) you should be able to have a 2.5MB
- Mac Plus equivalent. There are 16 and 25 MHz upgrades for the 512
- but they are more money.
-
- Remember that the above advice is dependent on your Mac being able
- to format double-sided (770-800KB) disks. If you can only use
- 400KB (single-sided) disks then you have a 512K Mac which must be
- upgraded with the 128K ROM and 800K drive kit. You might want to buy
- a used Mac Classic or something else for less than a $1000.
-
- If you do upgrade with the NewLife you should try to get a used
- hard drive. It makes an improvement on speed of use and convenience.
- I have seen System 7.0.1 (maybe System 7.1 too), System 6.0.8,
- Word 5.1, Excel 3+4, and most other recent software still be able to
- work on a 512Ke (double-sided disks) with the NewLife. You may want
- to use System 6.0.x for slightly faster responses.
-
- Note: There are no guarantees that you upgraded 512K is going to last
- very long. I have seen the 512Ke with NewLife still going after two years
- though...
